How to grow pea planting techniques and matters needing attention

Pea must be no stranger to everyone. It is a popular vegetable. Eating peas has the advantages of protecting eyesight, moistening intestines and defecating, so many people like to choose it to eat. Now there are a lot of people who want to plant it, but before planting, you need to know its planting technology, and there are a lot of things to pay attention to.

How to grow peas

1. Land selection: the fields with flat terrain and convenient irrigation and drainage are selected for planting, which requires that the soil contains high organic matter, from sandy loam to clay, and it is suitable to be slightly acidic to neutral.

2. Land preparation and bedding: select the land that has not planted legume crops in the previous year, apply sufficient basic fertilizer, and match the three ditches to ensure smooth drainage.

3. Sowing: autumn sowing is mostly carried out in the Yangtze River basin, sowing from late October to early November, or from late February to early March in early spring. In order to buy time, it is best to use plastic film mulching to promote early emergence; in South China, it is sown in stages from September to November, and harvested in winter and spring of the following year.

Planting techniques and matters needing attention of pea

First, planting techniques:

The main results are as follows: 1. Sowing methods can be on demand, sowing and strip sowing. The on-demand line spacing is 35 cm. The distance between plants is 10 cm, 2-3 grains per hole, and the amount of seed used is 10-20 kg.

2. The amount of seed used for sowing is 1520kg per mu. However, the practice for many years shows that the strip sowing method is the best, which is not only seed-saving and convenient for weeding, but also beneficial to fertilization and green pod harvest. The method is to paddle the soil moisture according to the standard of soil moisture ditch width of 30 centimeters and soil moisture surface width of 1.5 meters, requiring soil moisture to be flat and fine.

3. Sowing according to the specification of sowing width 0.15 meters and empty width 0.25 meters, and then covering with soil moisture ditch fine soil, the soil covering depth should be strict seed cover, and the soil covering depth is 0.2 mm. If the soil cover is too deep, the emergence of seedlings may be affected by the hardening of the soil surface in case of heavy rain.

4. If the soil cover is too shallow and the seeds are exposed, it is easy to be destroyed by birds, rats and other animals, resulting in a lack of ponds. The number of sown seeds per mu is controlled at 37000 ~ 43000. That is to ensure that the basic seedlings per mu 3.4. Ten thousand to forty thousand plants.

2. points for attention:

1. Shading and cooling measures in summer, due to high air temperature, fast growth, short growth period and small pods, timely shading net can effectively reduce the direct sunlight, reduce the air temperature and soil temperature, increase soil moisture, and promote the growth of individual plants. increase yield.

2. Peas cultivated in greenhouse in winter should be covered with plastic film in time to protect against cold and heat preservation. Before the coming of short-term strong cold current, cold-proof materials should be temporarily covered to protect young green bean pods from freezing damage.

Field management of pea

1. Chemical weeding. Before bud sowing, use 50% Acetochlor 100 ml or 20% diachlor 200 ml to 50 kg of water, spray the whole field. Pesticide application is best carried out when the soil is moist after rain, and human and animal trampling on the soil layer is prohibited after spraying, which can obviously improve the control effect.

2. Pest control. From the production practice in recent years, the occurrence of diseases and insect pests is relatively light. The occasional diseases and insect pests and their control methods are as follows: kill 6ml of 10% imidacloprid 20g plus enemy to control leafminer, aphids and cabbage insects. In the treatment of insects, 75% chlorothalonil can be added to control diseases at the same time.

The harvest of peas

Due to the different growing seasons and cultivation methods, there is a great difference in the days of picking green pods after flowering. In summer, due to high temperature and rapid growth of pods, it takes only 20 days from flowering to harvest, while in winter cultivation, it takes more than 30 days from flowering to harvest. Therefore, we should flexibly control the harvest date according to the use of pods and the degree of strong seeds. The pods that mainly eat green beans have been fully bulged, and the beans have reached 70% fullness, and the pods are about to be harvested when they begin to change color.

The planting method of pea is actually very simple. When planting, you need to choose a good site, and then sow seeds at the right time. The protective measures taken in winter and summer are different, so we should pay more attention to them. In the later stage of planting, we need to strengthen management, weeding and pest control work should be done in place, so as to ensure its growth.
