The Planting Method of Using Peach Tree and Soybean Intercropping to Control Ground Source Pollution in Slope Farming

Abstract

The planting method of using peach tree and soybean intercropping to control slope farmland source pollution, during which as: plant 8 rows of soybeans between two rows of peach trees, peach tree row spacing 360cm, row spacing 250cm, 75 plants / mu, soybean row spacing 40cm, row spacing 20cm, 8400 Plant / mu; or plant 10 rows of soybeans between two rows of peach trees, peach tree row spacing 380cm, plant spacing 250cm, 70 plants / mu, soybean row spacing 35cm, plant spacing 20cm, 9500 soybean plants / mu; or plant 12 rows of soybeans between two rows of peach trees , Peach tree row spacing 380cm, plant spacing 250cm, 70 plants / mu, soybean row spacing 30cm, plant spacing 20cm, 11000 plants / mu. This method makes the surface runoff reduction rate of sloping cultivated land reach 35-36%, the total nitrogen loss reduction rate reaches 45-49%, the SS loss reduction rate reaches 39-42%, and the output value reaches 6797-7431 yuan / mu at the same time, significantly controlling Ground source pollution from slope farming.

Description

Technical field [0001] The invention belongs to the technical field of agricultural planting, and particularly relates to a planting method for controlling the pollution of slope farming ground by using peach trees and soybean intercropping. Background technique [0002] Slope farmland is one of the important land use types in China. Slope farmland accounts for 63.9% of farmland in Yunnan Province. Existing rivers, lakes and other waters are often surrounded by slope farmland. Farming operations on slope farmland often cause farmland. Nutrient salts, pesticides and other pollutants in the water enter the water body through surface runoff, soil flow, farmland drainage and underground leakage, and form agricultural non-point source pollution. At present, agricultural non-point source pollution has become the main source of pollution in rivers, lakes and other waters. [0003] Irrational farming on sloping farmland leads to rainfall aggravating soil erosion and the formation of a lar...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects and deficiencies of the large surface runoff of the farmland and the high loss of nutrients such as nitrogen and phosphorus in the runoff caused by the existing sloping farmland planting mode, thereby providing a simple, easy-to-master, low-input Effective use of peach tree and soybean intercropping to control ground source pollution in slope farming
