[0002] Peanut is an important oil crop and economic crop in my country. It is also one of the few export-oriented bulk crop varieties with international market competitiveness in China. The national planting area and output rank second in the world. The current traditional planting methods are unscientific. Many years of heavy cropping and extensive field management, these factors affect the yield and quality of peanuts. Unreasonable management is not conducive to the growth and development of peanuts. When peanuts enter the pod-setting and fruit-full stages, peanuts will not receive effective nutrition and quickly enter the field. During the aging period, the peanut fruit cannot get component development, and some of the finally picked fruits are mature, and some are still in the state of white young fruit. The white young fruit is not fully developed and cannot be eaten, which reduces the peanut production and brings waste. For this reason, we propose A method for improving peanut yield by prolonging the growth period of peanuts is used to solve the above problems

Embodiment 1
[0025] The present invention provides a technical solution: a method for increasing peanut yield by prolonging the growth period of peanuts, characterized in that it comprises the following steps:
[0026] (1) Soil modification before planting
[0027] Select sandy land for deep plowing and irrigation. When the water evaporates to 50% of the soil moisture content, apply 850kg / mu of farmyard manure and 30kg / mu of compound fertilizer to the soil, and then deep plow and irrigate the soil again. Cover the soil with a layer of rice straw, and cover a layer of coarse sand and ceramsite on the rice straw;
[0028] (2) Management of Peanut Flowering and Needling Period
[0029] Plant peanuts normally after soil modification, pull out the weeds on the peanut root soil before the peanut flowering stage, and add urea 6kg / mu, potassium fertilizer 4kg / mu; when the peanuts enter the needle-setting stage, add 5kg of ammonium phosphate to the peanut root soil / mu, boron fertilizer 0.5kg / mu,...

[0038] The present invention provides a technical solution: a method for increasing peanut yield by prolonging the growth period of peanuts, characterized in that it comprises the following steps:
[0039] (1) Soil modification before planting
[0040] Select sandy land for deep plowing and irrigation. When the water evaporates to 50% of the soil moisture content, apply 950kg / mu of farmyard manure and 35kg / mu of compound fertilizer to the soil, and deep plow and irrigate the soil again. Cover the soil with a layer of rice straw, and cover a layer of coarse sand and ceramsite on the rice straw;
[0041] (2) Management of Peanut Flowering and Needling Period
[0042] Plant peanuts normally after soil modification, pull out the weeds on the soil of the peanut roots before the peanut flowering period, and add 8kg / mu of urea and 5kg / mu of potassium fertilizer; when the peanuts enter the needle-setting stage, add 5kg of ammonium phosphate to the soil of the peanut roots / mu, boron...

Abstract
The invention discloses a method for increasing the yield of peanuts by prolonging the growth period of peanuts. Peanuts are normally planted, and topdressing is carried out at the flowering and needle stage of peanuts, and the root soil is watered and irrigated every day; (3) After peanuts enter the pod setting stage, topdressing and insecticide are carried out again; (4) After peanuts enter the full fruit stage, remove For the yellowing and aging leaves of peanuts, dig holes around the roots of the peanuts to form picking holes at the roots of the peanuts, remove the ripe and plump peanuts, then add decomposed poultry manure and plant ash into the picking holes, fill the picking holes, and pour the soil into the peanut roots. Apply vitality fertilizer. Transform the soil to facilitate the growth of peanuts. During the growth of Husheng, topdressing fertilizers promotes fruit development. When the peanuts enter the senescence period, the mature fruits and senescent leaves are removed first, and the vitality fertilizer is used to promote the growth of peanuts again, which is convenient for the development of the remaining young fruits, thereby increasing the yield.
