When will spring peanuts be sown?

In the south, spring peanuts can be sown in the middle of February-March, while in the Yangtze River basin, spring peanuts can be sown in late March-April, and the suitable sowing time for spring peanuts in the north is from late April to early May.

Cultivation techniques of Spring Peanut

1. Bottom fertilizer for soil preparation

Spring peanuts should choose sandy soil with high soil fertility and convenient drainage and irrigation. 150 piculs of high quality farm manure, 100 jin of compound fertilizer and 2 jin of boron fertilizer should be applied per mu. After ploughing and raking, the three ditches should be opened according to the width of 5.2 feet and the depth of 0.6 feet.

2. Select varieties

It is suitable to choose with strong resistance, short growth period, suitable for close planting, high and stable yield, 300Mu 350 kg per unit area.

3. Sowing and close planting

Seed treatment before sowing, seed dressing with 25 grams of ammonium molybdate or 50 grams of peanut rhizobia per mu can increase production by 10-15%. Seed dressing should be done on the same day and sowing on the same day.

4. Fertilization

According to the law of peanut fertilizer requirement and soil quality and soil nutrient content, peanut special fertilizer should be applied, which can increase the yield by more than 10% compared with conventional fertilizer at seedling stage and early flowering stage. Spraying 0.3% borax solution in the peanut stage and 0.4% potassium dihydrogen phosphate solution in the fruiting period could increase the yield by 913%. Vigorously promote plastic film mulching and chemical weeding and promote early flowering and needle bearing, increase the full fruit rate and increase the weight of 100 kernels. At the same time, it can shorten the growth period and create favorable conditions for the second high yield. Spring sowing plastic film peanuts use plastic film 6 kg per mu. Before laying the film, use four taels of "pull cable" or "du er" herbicide with 50 kg of water to control weeds. After spraying, cover the plastic film to protect the topsoil layer containing herbicides.

5. Field management

Break the membrane and expose the seedlings in time, check the seedlings and replant. When the cotyledons are spreading, the membrane should be broken manually in time to prevent the seedlings from burning at high temperature, and it is appropriate for large cotyledons with holes to grow out of the ground. Replant the fields without seedlings and broken ridges in time. Timely ploughing and weeding, clearing ditches and draining after rain, maintaining soil permeability and increasing soil temperature are conducive to the early formation of rhizobium and the early development of strong seedlings.
