High-yield cultivation method of pea.

1 seed treatment

Sow carefully before sowing. You can pour the seeds into 40% salt water and take out the seeds that are not full and have pests floating on them. Sow in the sun for 2-3 days to improve the vitality of seeds and make them emerge early after sowing. In plots where peas are not planted, inoculating rhizobia at sowing time can increase the yield of peas.

2. Fertilization in the field

In order to increase the yield, we must first ensure that the soil has enough nutrients. Generally, 2000 kg of decomposed farmyard manure, 20-30 kg of calcium superphosphate, 7- 10 kg of potassium sulfate or 50- 100 kg of plant ash per mu can improve sufficient nutrients for the growth of peas in the whole growth period. For plots with poor soil fertility or early-maturing varieties with short growth period, 5- 10 kg urea can be added to the base fertilizer to promote strong seedlings and rapid formation of nodules.

Step 3: Sowing.

Looking for peas in the open field by hole sowing or drill sowing. Ridge planting can be used in the case of low humidity and low humidity. When it is dry, you can dig ditches and water them. Generally, two rows are sown in each border, with the hole spacing of 265,438+0 ~ 24 cm, and 3~4 seeds are sown in each hole. Before winter, the seedlings have 3-5 true leaves, so that the cold resistance of the seedlings can survive the winter safely, otherwise it is easy to die during the winter.

4. Tian Tuan management

If the nitrogen fertilizer in the base fertilizer is insufficient, when the seedlings grow to 7-9 cm, 5 kg of urea can be topdressing per mu to promote the growth of seedlings. After the seedlings turn green in the second year, intertillage and topdressing should be carried out, and at the same time, the seedlings with poor growth should be removed. Combined with watering and fertilizing once in the vigorous growth period, the demand is large in the pod setting period. Besides soil fertilization, foliar fertilizer is also needed. Before winter, intertillage should be carried out to protect the roots from freezing injury, and in cold areas, seedlings should be covered with a layer of straw or film in winter to protect them from overwintering.
