With the constant innovation of cultivation techniques and the selection and breeding of early-maturing varieties, the farming system of peanuts has also been developed from one-year-old farming to more than one-year-long cropping. It has grown from one-seater to intercropping, and the rotation pattern of the main producing areas has also continued. Variety. Due to the differences in topography, precipitation, and temperature, peanuts can be planted in three different ways, including flat cropping with flat land and furrowing, ridge cropping after deep-soiling, and drainage-assisted work. Ridge cultivation is divided into single ridges and double ridges.

Peanut cultivation technology

Peanuts on the soil requirements: The first is not heavy, otherwise it will cause pests and peanut root system itself poisoning. The second is that the pH of the soil should be between 6 and 7. The soil should be loose, air-permeable, sandy and sandy, and imaginary. The third is the need to contain organic and sufficient calcium.

After the soil conditions are met, the seeds should be sun-dried before the sowing, and the shells should be classified and classified. In order to reduce the bad seeds and diseases, the germicide and the seed dressing should be used to increase the seed germination rate and emergence rate.

Due to geographical differences, the optimum planting time is the northern region in late April to early May, the Yangtze River region sowing time before and after the Ching Ming Gu Yu, Xia peanut can be sown before before harvest 25-30 days, while the comparable mulching cultivation Cultivation of open field as early as 10-15 days.

In terms of sowing methods, there are mainly artificial on-demand, mechanical sowing, and shovel sowing. The requirements for mechanical sowing are that the depth of sowing is about 5 cm, and the ground where the ground temperature is low or the soil is high in humidity can be appropriately shone. However, the shallowest depth must not be less than 3 cm. On the contrary, it can be appropriately deepened, but no more than 6 cm. The main problems in machine seeding are unstable operation quality, lack of acupuncture points, missing grains, and a large proportion of three holes, inconsistent seeding depth, and uneven line spacing. Therefore, in order to solve the defects of the machine-seeding operation, we must first improve the quality of soil preparation, secondly control the amount of fertilizer applied to the machine, select seeds, and control the ridge spacing.

Peanut use of mulching cultivation process can yield more than 35%, yield can reach 70% -90%, the advantages are: increase in temperature, moisture mention soil moisture, drought waterlogging enhanced ability to maintain loose soil, and the like to reduce the loss of fertilizer. Commonly used polyethylene film, width 90 cm, thickness not less than 0.004 mm.

Peanut interplanting cultivation points

Intercropping peanuts with wheat is a cultivation method that aims to increase the cropping index and make full use of the land and light energy resources. The main technical points of intercropping wheat are to reserve peanuts on the basis of wheat specifications sowing. Double lines and interplanting can be 0.8 meters to open the car, sowing two lines of wheat per car, after soaking two lines of peanuts after 0.5 meters. The second is to use good seeds and timely sowing. Wheat should use high-yield and high-quality varieties that are early-maturing, dwarf, and lodging-resistant, and peanuts should use high-yield varieties with earlier maturity, compact plants, and high shade tolerance. It is generally preferred to plant 25-30 days before the harvest of wheat. The symbiotic period of peanut seedlings and wheat is controlled within 15-20 days. The third is a reasonable increase in fertilization material, because wheat growth in the early stages of peanut covered by a certain subtle influence of wheat, so when sowing wheat under the premise of applying base fertilizer, early application of peanut seedlings, clever application of top dressing is the key to obtain peanut high yield. After the peanuts are seedlings, they can use 7-8 kilograms of urea to raise seedlings, and 0.2% of potassium dihydrogen phosphate can be used as the foliar dressing for spraying 1-2 times in the flowering stage.
