Detailed Explanation of Field Management Techniques for Peas

Peas are a common seasonal vegetable in our daily lives, generally sold only during a fixed season. Its tender pods, seeds, as well as its young shoots and sprouts are all edible, so it can be said to be not only a legume vegetable but also a sprouting vegetable. Peas have strong adaptability to the environment and can be grown throughout China, so today let us take a look at how field management work for peas is carried out.

1. Cultivation and Weeding

The growth rate of pea seedlings is relatively slow, so timely cultivation and weeding should be carried out to prevent weeds from growing rampantly, causing weed infestation and affecting the normal yield of peas. During the growth process of peas, generally three rounds of cultivation and weeding are needed. The first cultivation is shortly after the seedlings emerge, roughly when the seedlings have grown to about 10 cm. The second cultivation is generally when the pea seedlings have grown to about 25 cm, while the third cultivation only needs to be carried out before flowering, mainly based on the growth conditions of the pea seedlings and the growth conditions of the weeds.

2. Pinching and Staking

When the pea seedlings have grown to about 30 cm, in order to make the pea seedlings produce more side branches and increase the yield of peas, the pea seedlings need to be topped and pinched, removing the heart leaves to promote the growth of side branches. After the side branches have grown to a certain extent, the growth of lower-level branches is further promoted, until the pea seedlings form a complete plant shape, and finally topping is done to inhibit the continued growth of the pea seedlings. And when pinching, stakes should be set up, preferably one stake for each plant, with the stakes connected by thin ropes, and the seedlings guided onto the stakes to climb and grow, so as to increase the yield of peas.

3. Watering and Drainage

During the growth process of peas, if dry weather occurs, the soil is dry, and there is no moisture, timely watering should be carried out to prevent the pea plants from dying due to lack of water, especially during the flowering and pod-setting stages of peas, when the water demand is very high. If the water supply is insufficient, the impact on yield and quality is very great. But if cloudy and rainy weather occurs, or if there is continuous rainfall, then we should promptly dredge the field ditches for drainage, and at the same time observe whether there are hollows and depressions in the field, and try to drain the accumulated water from the field.

4. Reasonable Fertilization

Peas have strong nitrogen-fixing ability. When base fertilizer is applied normally and soil fertility is sufficient, and the nitrogen content in the soil is relatively high, there is no need for nitrogen topdressing. However, the growth of peas has a relatively high demand for phosphorus and potassium fertilizers. Generally, we mainly supplement the phosphorus and potassium fertilizer needs of peas to promote the growth of peas and increase the pod-setting rate of peas. During the flowering and pod-setting stages of peas, it is necessary to appropriately spray foliar fertilizer and caiguo zhuangdiling, which can enhance the pollination success rate of peas and increase the pod-setting rate of peas.

5. Thinning Flowers and Leaves

During the flowering stage of peas, especially at the full flowering stage, some flowers need to be appropriately removed, otherwise the pollination rate and pod-setting rate of peas will be affected, especially because insufficient nutrition leads to serious flower and pod drop in the later stage. In addition, during the later growth process of pea seedlings, the branches and leaves will become increasingly dense. In order to carry out sufficient photosynthesis and maintain good ventilation, some branches and leaves of peas need to be appropriately removed.

If the above points of work are generally done well in the field management of pea planting, then the planted peas will usually be high-yield and high-quality. Of course, one more point to note is to do a good job in the prevention and control of pests and diseases.
