Planting time and method of pea, whether pea is self-pollination or cross-pollination

Peas are self-pollinating plants. In the butterfly-shaped Corolla of pea flowers, a pair of petals are always tightly wrapped around stamens and pistils, which determines that pea pollination is self-pollination and closed-flower fertilized plants. Other self-pollinating plants include barley, wheat, soybeans, beans, henna and so on.

Pea is self-pollinating, because it is a monoecious plant, and the pollination time of pea is closed pollination before flowering, but if you want to improve its pollination rate, you need to spray some drugs to promote bud growth before flowering, about 1-2 times can achieve the effect of increasing pollination rate, and the yield of pea will naturally increase.

Peas are strictly self-pollinating and closed-pollinated plants, which are pollinated before flowering, so option An is correct.

Peas are self-pollinated and closed-pollinated. This variety of peas looks so beautiful, with red flowers and white flowers, peas are pollinated by wind and insects, peas are pollinated when they bloom, and there is little possibility of genetic mutation. Pea pollination, self-pollination and closed pollination, pea self-pollination, closed pollination, so it is pollination before flowering. Bean flowering stage pollination is the form of self-pollination.

Peas are self-pollinated. According to the relevant public information, the pollen in the pea stamens will automatically fall on the pistil stigma to complete the pollination process, which belongs to self-pollination, and peas can also be pollinated by external force. generally speaking, they can rely on wind and insects to help pollinate, so as to achieve a better pollination effect. Pea, the name of traditional Chinese medicine, is the seed of Pisumsativum of pea genus of Leguminosae.

Planting time and method of pea

The main results are as follows: 1. The requirement of planting method for loam is not too high, as long as the soil layer is deep and the salinity is low, which is helpful to the survival of seedlings and the growth of crops. Choose the appropriate pea variety according to the need, after sowing, it is necessary to loosen the soil shallowly, keep it soft and help the root growth, and the seedling growth will become strong. Wait until the seedlings grow out, to remove weeds in time, can not compete with the seedlings for nutrients.

Peas are seasonal vegetables, so they can be planted all the year round. The planting methods of pea are as follows: plot selection, seed selection, cultivation density, combined application of base fertilizer, irrigation management, weeding and disease prevention. The planting time of peas can be planted all the year round. When planting peas, the sowing time can be flexibly controlled according to the stubble and season, and the appropriate sowing date can also be determined according to the time requirements of pods on the market.

3. Time: planting should be carried out at a suitable time as far as possible. in general, it is best from March to May in spring. If the seeds are planted at this time, the seeds will germinate more easily and grow better. Autumn can also be planted, preferably in September, when the climate is relatively mild and suitable for its growth.

4. Planting in spring and autumn: in the planting time and method of pea, we choose to plant it in spring and autumn, when the climate is cool, it can meet the cool growth habit of pea. Generally, for the north of the Yangtze River, because of the low temperature, spring sowing is mostly carried out from March to April in spring, while in the south, sowing is carried out after September in autumn.

5. Planting time peas have strong adaptability to the environment, which can be planted from February to April in spring, May to June in summer, August to October in autumn and November in winter, but sunscreen measures should be taken in summer and warm measures should be taken in winter.

6. First of all, you should choose a good place for land leveling and planting peas. As the root system of this plant is well developed, it is resistant to drought but not waterlogging, so it must be planted in a dry environment. Deep and well-drained soil can also prevent the roots from being flooded, which is very helpful for their breathing. In addition, whether the soil is fertile or not also plays an important role in the development of plants. Sowing time peas are sown at different times in different areas.

The methods and steps of planting peas

Plot selection: peas are suitable to be planted on fertile and clayey soil, and the land with deep soil layer and good drainage has the best effect. Seed selection: select varieties that are suitable for local climate and resistant to diseases and insect pests, such as mung bean No. 3, Pea No. 2 and so on. Cultivation density: row spacing 40 cm 60 cm, plant spacing 6 cm 10 cm. Sow about 25,40kg per mu. Combined application of base fertilizer: 15 to 20 tons of mature organic fertilizer per mu, and 150 to 300 kilograms of compound fertilizer or urea.

Before planting pea, it is necessary to select fertile sandy loam and carry out deep ploughing to ensure the permeability and drainage capacity of the soil, so as to avoid rotting roots. Before planting, it is necessary to apply rotten farm manure as base fertilizer. Seed selection and sowing pea seeds can generally be used with mature peas as seeds. When selecting seeds, you should pay attention to choosing large and full seeds and basking in the sun for a few hours.

The planting method of pea is divided into soil preparation, fertilization, sowing time, sowing method, field management and harvest. Prepare the ground. The requirement of pea for loam is not high, as long as the soil layer is deep and the degree of salinity is low, which is beneficial to the survival and growth of seedlings. Spring sowing varieties require deep ploughing in autumn, with a tillage depth of about 15-25cm. The top of the spring is raked and crushed.

Land selection and ploughing: when planting peas, choose to plough the land with deep soil layer and apply base fertilizer. Soak and sprout: pick full seeds and soak them, remove them and wrap them with cotton cloth to accelerate germination. Planting into the soil: dig planting holes at a distance of 20 cm and sow seeds on demand. Field management: grow 4 true leaves and transplant with a height of 8 cm.

How to grow peas

Plot selection: peas are suitable to be planted on fertile and clayey soil, and the land with deep soil layer and good drainage has the best effect. Seed selection: select varieties that are suitable for local climate and resistant to diseases and insect pests, such as mung bean No. 3, Pea No. 2 and so on. Cultivation density: row spacing 40 cm 60 cm, plant spacing 6 cm 10 cm. Sow about 25,40kg per mu. Combined application of base fertilizer: 15 to 20 tons of mature organic fertilizer per mu, and 150 to 300 kilograms of compound fertilizer or urea.

In general, peas should be sowed by spot sowing. 2-6 seeds should be planted in a hole with an interval of 10-20 cm. After sowing, they should be covered with soil 5-6 cm thick. If the climate is dry, they can be thicker. When the seedlings grow to 8-10 cm high and have 2-4 leaves, they can be transplanted.

Cultivating strong seedlings of suitable age is one of the links to increase the yield of pea, and the seedling age is not the same in different seasons and different conditions. The seedling age is 20-25 days in autumn and winter, and 30-35 days in winter and spring, and 35-40 days in spring and summer.

When will the peas be planted? When to grow beans, what time is good?

1. Peas are sown at different times in different areas. In the areas north of the Yangtze River, most of them are sown in spring, which is usually carried out in March-April and can be harvested from July to August. On the other hand, the area south of the Yangtze River is sown in autumn, and the seeds will be sown in October-November and harvested in April-May of the following year. Soaking seeds to accelerate germination peas need to be germinated before sowing.

2. The planting time of overwintering peas is suitable to be planted from October to November every year, and can be harvested from April to May of the following year. When planting overwintering peas, if sowing too late, it will lead to slow growth of plant roots and lower yield of overwintering peas. If sowing too early, it will cause the seedlings of overwintering peas to freeze to death.

3. There is no need to postpone. Beans are generally planted from mid-late February to the end of March in the lunar calendar, and can be planted in the Gregorian calendar from late March to the end of April. After this time, beans are generally planted at the bottom of the harvest. Melons and beans are planted around the Qingming Festival, so there are many crops that can be planted at this time, such as melons, beans, except peas and broad beans, which should be planted in the ninth month of the lunar calendar.

4. Vegetables suitable for growing in spring (January to March of the lunar calendar) include chili, green pepper, colored pepper, onion, cauliflower, sweet pepper, pea, celery, lettuce, shepherd's purse, rape, spinach, Toona sinensis, spring bamboo shoots, Malan head and bottle gourd. This is also a good time to grow leeks. At the end of spring, you can consider planting lotus mist.

5. In the Yellow River basin, under the natural environment, the planting time of grain is roughly as follows: spring crops, such as millet, rice, corn, sorghum and other crops, began farming in late April. Nong Yan said: around Grain Rain, he planted melons and beans, sowed melons and reaped melons. That's what it means. Summer crops: the above cereal crops should be planted in the first and middle of June, and in late June at the latest. If it is in the area outside the customs, it should be postponed for one month.

6. Gu is one of the 24 solar terms, which usually occurs between April 19 and April 21 every year. In ancient Chinese farming culture, Grain Rain is regarded as the last solar term in spring, and it is a suitable time to sow melons and legumes. According to the traditional explanation method, Grain Rain before and after planting melons and beans have the following basis and suggestions: soil temperature: before and after Grain Rain, the soil temperature gradually increased in the late spring.

Planting method and time of pea

The adaptability of pea planting time is relatively strong, so it can be planted in spring, autumn and winter. in the middle and lower reaches of the Yangtze River, the most important thing is overwintering cultivation and sowing from late October to mid-November. it can also be sowed in February-March in spring, the growth cycle is relatively short, and it can be harvested in summer.

Select land preparation, select plots with deep layer and strong drainage performance to sow, and the land needs to be turned over before sowing; sowing time can be carried out from March to April in the north and from October to November in the south; soaking and accelerating germination, it is necessary to soak the seeds in clean water, fish out the dry and shrunken seeds, and sprout with gauze; sowing method, the germinated seeds can be evenly sowed to the soil.

First of all, you should choose a good place to flatten the land and grow peas. As the root system of this plant is well developed, it is resistant to drought but not waterlogging, so it must be planted in a dry environment. Deep and well-drained soil can also prevent the roots from being flooded, which is very helpful for their breathing. In addition, whether the soil is fertile or not also plays an important role in the development of plants. Sowing time peas are sown at different times in different areas.

The planting time of pea is different in different areas. Peas are mostly sown in spring in the north of the Yangtze River, usually in March-April, and can be harvested in July-August, while those in the south of the Yangtze River are sown in autumn. Sowing is in October-November and harvest in April-May of the following year.

Planting time and method: planting time: peas have strong adaptability to the environment, which can be planted in February to April in spring, from May to June in summer, from August to October in autumn and in November in winter. however, good sun protection measures should be taken in summer and warm measures in winter. Soil selection: choose loam or sandy loam with deep soil layer, high organic matter content and good drainage and irrigation conditions.
