Method for increasing yield of peanuts by prolonging growth period of peanuts

Abstract

The invention discloses a method for increasing the yield of peanuts by prolonging the growth period of the peanuts. The method includes the steps of (1) selecting sandy land, conducting deep turning and irrigation, and applying a farmyard fertilizer and a compound fertilizer to the soil; (2) after the soil transformation, normally planting the peanuts, conducting topdressing in the flowering and seed growing stage of the peanuts, and daily watering and irrigating the root soil; (3) after the peanuts enter a pod-forming period, conducting topdressing again and taking an insecticidal measure; (4) after the peanuts enter the fruit-filling period, removing the yellow and senescent leaves of the peanuts, digging holes in the peripheries of the roots of the peanuts till picking holes are formed in the roots of the peanuts, removing the ripe and full peanuts, then adding decomposed poultry and livestock manure and plant ash to the picking holes, filling and covering the picking holes, and applying a fertile fertilizer to the root soil of the peanuts. The soil transformation is conducted to facilitate the growth of the peanuts, during the growth of the peanuts, topdressing is conducted many times to promote fruit development, and when the peanuts enter the senescence stage, the mature fruits and the senescent leaves are removed first and then the fertile fertilizer is applied to promoting the growth of the peanuts again and facilitating the development of remaining young fruits, so that the yield is increased.

Description

technical field [0001] The invention relates to the technical field of peanut planting, in particular to a method for increasing peanut yield by prolonging the peanut growth period. Background technique [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 i...

[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
