Using plastic film to cover peanuts, the benefit will be doubled.

After mulching with plastic film, peanuts can increase the ground temperature and sowing, and the effective accumulated temperature can be increased by 200-300. it can resist drought, disease and weeds, mature 10-15 days earlier than bare peanuts, increase production by 20% ─ 50%, and the benefit per mu is more than 1000 yuan.

Cultivation techniques of peanut covered with plastic film:

I. selection of improved varieties

The middle and late maturing varieties with large production potential per plant, developed root system, disease resistance and lodging resistance, high quality and high yield should be selected. Our city chooses Haihua No.1.

Second, choose a good place

Choose the sandy loam with fertile soil, flat terrain, uniform soil fertility and smooth drainage and irrigation, and the mountain area can also be planted in the gap of young trees.

Third, apply fertilizer with the prescription

3000 kg of agricultural fertilizer, 15 kg of ammonium sulfate, 10 kg of diammonium phosphate and 5 kg of potassium sulfate were applied per mu. Fertilizer should be applied deeply and there should be a certain isolation layer with the seeds to prevent seed burning.

IV. Fine land preparation

Film-covered land must be deeply ploughed before winter or early spring, ploughing depth of about 20 cm, deepen the mature plough layer, when raking the soil should pay attention to remove the residual stubble, bumps, stones, so that the soil is fine, the ground is flat, so that the upper loose and lower solid.

Fifth, make beds

The width of the bed is 1 meter, the height of the bed is 10-12 cm, the width of the bed is 70-80 cm, and the distance between the rows of the bed is 35-40 cm.

6. Sowing seeds at the right time to ensure the whole seedling

Mulched peanuts should be sowed at the right time according to soil moisture and temperature. From April 20 to May 5, our city will sow 9000 holes per mu, 15 cm apart, 2 grains per mu and 18000 seedlings per mu, and then cover soil with 43% rope emulsion 250g, spray 50kg of water on the bed surface and cover it with 0.005 mm ultra-thin plastic film to achieve continuous sowing, soil mulching, herbicide spraying and film mulching. Make sure to sow the seed in a flash to protect the whole seedling.

VII. Strengthen field management

1. After checking the field to protect the film and cover the film, we should often check and find that the film is blown up by the wind to use soil pressure to ensure the integrity of the film.

two。 Diaphragm to help seedlings unearthed peanut seedlings just unearthed, to artificially break the membrane to help seedlings unearthed, and then seal the seedling eyes with fine soil, when the seedlings grow a real leaf, check again, now that the first pair of lateral branches grow in the film, it is necessary to pick them on the film by hand in time to let the side branches grow healthily, to clear the squatting seedlings after the seedlings come out, and to promote sprouting and replanting in the serious lack of seedlings.

3. The serious land for the control of underground pests can be sprinkled with 0.5 ml / mu, 1 kg, 5% A, 5% A, 5% intercalated agent and 15 kg of fine soil.

4. Spraying paclobutrazol for luxuriant peanuts can control the aboveground growth by spraying 75g / mu and 75g / mu of paclobutrazol to 50 kg of water. Promote the development of milk system, increase the number of fruit needles, increase fruit plumpness and 100 fruit weight, and increase the yield by 15%, 48%.

5. Timely irrigation of the land with irrigation conditions, in the flowering and apple grain-happy period, it is found that the soil water in the plough layer is less than 40%, it should be irrigated in time to ensure that there are many flowers, fruits and full fruits.
