The latest key points of high-yield planting of pea

Pea is a kind of vegetable that we are very familiar with. We can not only eat its fresh beans, but also tender pods have become a delicacy on the table. Many farmers are responding to the fact that pea cultivation is difficult to manage and the yield is low, but in fact, they have mastered the correct planting method. It is quite simple to have a high yield of peas. Let's take a look.

1. Seed treatment

To plant carefully before sowing, you can pour the seeds into 40% salt water and fish out the unsubstantial and pest-infested seeds that float on them. In order to improve the seed vigor after sowing for 2-3 days, the pea yield can be increased by inoculating rhizobium in the land where pea has not been planted.

2. Fertilization in the field

In order to increase the yield, we must first ensure that the soil has sufficient nutrients. Generally, 2000 kg of rotten farm manure, 20 kg of superphosphate, 10 kg of potassium sulfate or 50 kg of plant ash are applied per mu. This can increase sufficient nutrients for the whole growth period of pea. For the plots with poor soil fertility or early-maturing varieties with short growth period, 5-10 kg of urea can be added to the base fertilizer to promote strong seedlings and quickly form root nodules.

3. Sowing seeds

Look for the method of hole sowing or strip sowing in the open field of peas. In low humidity and low humidity, you can use the method of ridge cultivation. In times of drought, you can open a ditch to water it. Generally, each row is sown in two rows, the distance between holes is 21cm, and each hole is sown with 3 grains. Before the beginning of winter, the seedlings already have 3-5 true leaves, so that the seedlings can survive the winter safely, otherwise they are easy to die during the winter.

4. Field management

If the nitrogen fertilizer in the base fertilizer is insufficient, when the seedlings grow to 7-9 cm, 5 kg of urea per mu can be applied to promote the growth of the seedlings, ploughing and topdressing the seedlings after turning green in the second year, and dredging the seedlings with poor growth at the same time. In the period of vigorous growth, combined with watering and applying one-time fertilizer, there is a great demand in the podding period, in addition to soil fertilization, foliar fertilizer is also needed. Ploughing and cultivating the soil before the beginning of winter, root protection against cold, in cold areas in winter can be covered with a layer of straw or film to protect seedlings safely through the winter.
