A high-yield cultivation method of drip irrigation under film in sandy desert soybean

Abstract

The invention relates to an under membrane drop irrigation high yield cultivation method of sandiness desert soybean. The specific procedures of the under membrane drop irrigation high yield cultivation method comprises the following: initially selecting a high quality variety which is good in growth vigor, strong in stress resistance and high in yielding ability on the sandiness desert, and then enabling the variety which is well selected to disposably finish paving a drop irrigation belt, a paving membrane and sowing operation through a on membrane dibble seeder, the drop irrigation belt is connected with a drop irrigation system, and starts drop irrigation under the membrane and using topdressing along with water. The under membrane drop irrigation high yield cultivation method of the sandiness desert soybean has the advantages of being capable of enhancing land utilization rate of the sandiness desert, improving economic benefit of sand prevention and desertification control in a prior period, and simultaneously utilizing nitrogen fixation of the soybean to steadily augment the land capacity of the sandiness desert.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation in the agricultural technology, and specifically relates to a high-yield cultivation method for planting soybeans on a sandy desert. Background technique [0002] In early 2011, the State Council Information Office held a press conference on the fourth national monitoring of desertification and desertification. It was learned from the press conference that in order to grasp the latest changes in desertification and desertification in my country, the State Forestry Administration organized the fourth national desertification and sandification monitoring work. Monitoring results show that by the end of 2009, the national desertified land area was 2.6237 million square kilometers, and the desertified land area was 1.7311 million square kilometers, accounting for 27.33% and 18.03% of the total land area respectively. Xinjiang has unique water, soil, light and heat resources. The sunshine ti...

Problems solved by technology

[0007] The purpose of the present invention is to provide a high-yield cultivation method for soybeans in sandy deserts with drip irrigation under film, which is an advanced and scientific irrigation technology, to solve the problem of sandy deserts due to the low water and fertilizer retention capacity of sandy deserts. Due to the defects of low desert fertility and low water and fertilizer retention capacity, making full use of the environmental factors of light, heat, and air in the sandy desert has improved the land utilization rate of the sandy desert, and at the same time, the nitrogen fixation of soybeans has been used to continuously improve the sandy desert. Soil fertility, to achieve the purpose of sand prevention and control at the same time has good economic benefits, and the technology is simplified, easy to popularize
