Problems solved by technology

[0004] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. Planting peanuts on saline-alkali land often has unsatisfactory economic benefits. Although the film-mulching cultivation method is conducive to the accumulation of dry matter, it can Improve the transport and distribution rate of dry matter, promote plant vegetative growth and reproductive growth, but the effect is still not ideal for planting on saline-alkali land

Embodiment 1

[0037] In this experiment, field planting was carried out in 8 companies of 38 regiments from 2020 to 2021. The previous crop was corn and the pH was 8.21. The experiment was designed according to the randomized block group, and three treatments were set up: covered with ordinary plastic film, not covered with plastic film and covered with degradable film, and each treatment was repeated 3 times.

[0038] The land used for each test is: the length of the plot is 10m, the width is 3.7m, there are 8 rows, the row spacing is 0.46m, and the area of ​​the plot is 37m 2 , density 15 plants·m -2 .

[0039] Sowing time is May 10, drip water on May 14, and apply urea 28.26kg·667m during the whole growth period -2 , Potassium dihydrogen phosphate 17.94kg·667m -2 (phosphorus content 2.75%, potassium content 28.72%), superphosphate 16kg·667m -2 , (calcium content 12%, phosphorus content 14-20%, sulfur content 9%), diamine phosphate 30kg·667m -2 , (nitrogen content ≧ 18%, available ph...

Abstract

The invention discloses a method for increasing the yield of peanuts planted in saline-alkali soil, and belongs to the technical field of agricultural planting. The planting method comprises the following steps that planting is conducted in a degradable film mulching mode, irrigation is conducted in a drip irrigation mode in the planting process, and fertilization is conducted in the whole growth period. By means of the planting method, the main stem height, the side branch length, the total branch number and the fruiting branch number of the peanuts can be remarkably increased, the salt content of the saline-alkali soil is effectively controlled, the net photosynthetic rate from the flower needle stage to the mature stage of the peanuts is remarkably increased, the kernel rate and the full fruit rate of the peanuts are increased, and the yield increasing effect is remarkable. Compared with a traditional film mulching planting mode, the method can further increase the yield of peanuts planted in the saline-alkali soil.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for increasing the yield of peanut planted in saline-alkali land. Background technique [0002] Peanut is one of the important oil crops, which has the characteristics of strong adaptability and great potential for increasing production. Peanuts have a variety of cultivation methods. Compared with bare land, plastic film mulching can improve soil temperature, humidity and water use efficiency, reduce water evaporation, enhance plant drought resistance, inhibit weed growth and increase production. Compared with the planting method of mulching, the planting method without mulching reduces the activity of soil microorganisms, makes the soil easy to compact, and hinders the growth of plants. Studies have shown that film-mulching planting significantly increases the height of the main stem of peanuts, and promotes the growth of peanut main stems and side branch...
