How to put Spring Peanut on the Market in advance and plastic Film mulching cultivation technique of Spring sowing Peanut

Spring sowing peanuts, mulching, can improve ground temperature, early sowing, promote growth and development, can be listed early, increase benefits, improve the rate of full fruit, that is, increase production and improve quality. In order to better promote the plastic film mulching cultivation technology of spring sowing peanut and realize high quality and high efficiency of peanut, the plastic film mulching cultivation technology of spring sowing peanut is introduced as follows:

Field Management of Plastic Film Peanut

I. Preparations:

1. Select excellent seeds and prepare mulch film. Excellent seed is the key to whole seedling and strong seedling, which can improve quality and improve quality. Jihua 3, Jihua 2, Luhua 14 and other varieties can be selected, and peanut seeds for drying, seed selection. The thickness of plastic film is 0.05-0.08 mm, and the dosage per mu is about 3.5 kg.

2. Soil preparation, fertilization and soil moisture cultivation. 5 square meters of coarse fertilizer (decomposed chicken manure or manure), 70-100 kilograms of calcium superphosphate, 20-30 kilograms of ammonium bicarbonate, 12-16 kilograms of potassium sulfate, 1 kilogram of boron sand, 1 kilogram of ferrous sulfate or more than 100 kilograms of compound microbial organic fertilizer, 50-75 kilograms of calcium superphosphate, 10-12 kilograms of potassium sulfate and 12-13 kilograms of urea are applied to each mu, and all organic fertilizer and 2/3 of chemical fertilizer are applied at the bottom in combination with soil preparation.

Second, timely sowing and mulching, reasonable dense planting.

The suitable sowing time is April 10-15, that is, the soil temperature of 5 cm is stable through 12℃. The sowing density is planted according to the big and small rows, the small row spacing is 30cm, the large row spacing is 55-60cm, the hole spacing is 17cm, 2 seeds are planted in each hole, the seed amount per mu is 15 kg, and the sowing depth is 3 cm. After sowing, 2-3 liang of 50% acetochlor herbicide is mixed with 50-60 kg of water, evenly sprayed, and then covered with film. The film should be flat, tight, and firm. The film should be removed by windbreak to cause moisture loss and temperature reduction.

III. Field management:

1. Seedling management. Open the membrane and release the seedlings. When the buds are on the top soil, open the membrane and release the seedlings in time. When the cotyledons are developed, the membrane is broken manually in time to prevent burning seedlings. After putting seedlings, the base of seedling stems should be pressed with soil in time. The time of seedling release is generally before 10:00 a.m. on sunny days and after 4:00 p.m. on cloudy days. Timely check seedlings and supplement seedlings.

2. From flowering to podding. Flowering next needle stage is sensitive to water response, at this time in case of drought, can not next needle, should be based on soil moisture content, in case of drought timely watering, in order to increase the number of pods, pod expansion stage, watering once, in order to achieve the purpose of yield increase.

3. Combination of phase control to increase and stabilize production. Peanut pod stage is in rainy season, precipitation, fertilizer, density of the plot easy to appear prosperous growth (plant height more than 40cm, full flowering pod is chicken mouth), timely use 2 liang 15% paclobutrazol mixed with 50 kg water spray to prevent excessive growth, generally in July 10.

4, full fruit period full fruit period, in case of drought to water once, in order to improve the peanut full fruit rate.

5. Control diseases and insect pests and prevent premature aging. Due to plastic film mulching, peanut growth and development early, late easy premature senescence, in the peanut pod stage to mature stage, root topdressing, foliar spray 1-2% urea solution or 0.2-0.3% potassium dihydrogen phosphate solution or 50% carbendazim 500 plus 0.1% ferrous sulfate or 0.5% urea plus 0.2% potassium dihydrogen phosphate, 50kg of solution per mu, can control peanut leaf spot, cotton bollworm.

IV. Timely harvest.

Peanut mature whether timely harvest of peanut can be high yield and harvest, peanut mature mark is the upper part of the peanut plant there are several green leaves, middle leaves yellow, lower leaves off, pod clear network, with this variety characteristics. Harvest time, under the same conditions of varieties, plastic film peanut can mature 7-10 days ahead of schedule, generally harvested in the middle and late August. Finally, it is necessary to clean the residual film to prevent white pollution and protect the land environment.
