The yield of peas is not high? Master these five planting techniques

Pea is a kind of vegetable that everyone is familiar with. Now we can not only eat fresh pea, but also tender pea pods. Some friends say that planting peas is difficult to manage and the yield is too low. In fact, as long as you master the correct planting method, high yield of peas is still very simple. Let's get to know it together.

Peas planting

1. Seed treatment

Before sowing, select seeds, pour the seeds into 40% salt water, and remove the floating seeds that are not full and pests. Expose the seeds 2 to 3 days before sowing to improve seed viability and emerge early. In plots that have not been planted with peas, inoculation of rhizobia during sowing can increase the yield of peas.

2. Field fertilization

Generally, 2,000 kg of decomposed farmyard manure, 20-30 kg of superphosphate, 7-10 kg of potassium sulfate or 50-100 kg of plant ash are applied per acre. For fields with poor soil fertility and early-maturing varieties with a short growth period, 5-10 kg of urea should be added to the base fertilizer to grow into strong seedlings early and quickly form nodules.

3. Sowing

Open-field cultivation of peas generally adopts flat-border hole sowing or drill sowing. Low-wet land can be planted in ridges. When drought is used, peas are sown in two rows with a hole spacing of 21-24 cm, and 3 to 4 seeds per hole. There should be 3 to 5 true leaves before winter, because the seedlings in this period are more resistant to cold.

4. Field management

â‘  Top dressing

If the nitrogen in the base fertilizer is insufficient, when the seedling height is 7-9 cm, 5 kg of urea can be topdressed per mu to promote the healthy growth of the seedlings. After the seedlings return to green in the early spring of the second year, cultivating and topdressing are used to remove poorly growing or too dense seedlings. During the vigorous growth period, watering and topdressing should be carried out once, compound fertilizer 20-30 kg per mu, 10-15 kg superphosphate, flushing or furrowing. Topdressing after pod formation, apply 5-10 kg of urea per mu, and spray 0.2% potassium dihydrogen phosphate on foliage during pod formation.

â‘¡ cold protection

Cultivate the soil during cultivating to protect the roots from the cold. In cold areas, you can sprinkle a layer of straw on the border surface or cover the old film to protect the seedlings from the winter.

â‘¢Plant management

The trailing vines are inserted before the vines are drawn, and most of them use the "person" frame. Simultaneous pruning, leaving 3~4 branches at the base and 1~2 branches at the upper part.

5. Harvest

The peas that are used as tender pods are harvested 8-10 days after the flower fades, and the pods have fully grown and stopped elongating. Starting with fresh bean grains, the pods are harvested 15 to 18 days after the flower fades, and the bean grains are obviously bulging and the seed coat is not hardened.
