Winter pea cultivation technology

It has a high protein content, accounting for 22% -24% of the weight of the kernel, and is rich in various amino acids necessary for the human body, as well as fat, carbohydrates, minerals and carotene. The open-field cultivation of peas in our county generally winters with seedlings. The harvest starts in early April to late May of the following year. The main cultivation techniques are as follows:

First, select good varieties. There are many varieties of peas suitable for popularization in our county. The early-maturing dwarf upright hybrid peas such as Zhong Pei 4 and Zhong Pei 6 are better.

2. Preparing the ground finely and applying sufficient base fertilizer. Avoid continuous cropping of peas. Before sowing, you need to prepare the ground finely, make a good hoe, and apply sufficient basal fertilizer. Generally, you should apply 800-1500 ㎏ of rotten pigs and cow pen dung per acre, and about 25 过 of superphosphate.

Third, timely sowing, narrow rows of dense planting. Winter sowing peas are generally sown from late November to early December. They are usually planted by hole sowing, with a row spacing of 33㎝ and plant spacing of about 17㎝. Sowing 2-3 seeds per hole, 6-8 亩 per acre, and 3-4㎝ covered with soil. . Before sowing, water the bottom to keep the soil moist. After sowing and before emergence, rodent medicine should be placed on the field side to prevent rodent harm.

Fourth, strengthen field management. Seedlings should be weeded 2-3 times. That is, when the seedling height is 5-8㎝, the middle tillage will be carried out * a little deeper, and it is better to use slack pine compacted land; when the seedling height is 10-13㎝, the soil will be raised during the second tillage to protect the roots from the cold, which can be shallow. After emergence, we need to control the supply of water and fertilizers, so that we can survive the winter with small seedlings, which is not susceptible to freezing. After returning to the spring in the spring, combine the seedlings that have been over-dense in the middle cultivator, and apply the seedling fertilizer once before setting up the stent, and 1-2 times after the pods (acupoint application), and apply ternary compound fertilizer 5-10 复合 per mu. In case of heavy rain in spring, the ditch must be drained in time to prevent damage.

Fifth, control pests. Pea diseases mainly include downy mildew, powdery mildew, brown spot, etc. It can be sprayed 2-3 times with 50% metalaxyl or 90% ethyl aluminum phosphate 500-600 times, and can also be carried out with carbendazim, tobbutzine and other pesticides. Prevention. Pea pests are mainly aphids, green worms, leaf miners, etc., which can be controlled by spraying 20% ​​deltamethrin 2000-2500 times.
