Technology for planting vetiver grass for rice stem borer luring, pollutant intercepting and soil fixation in paddy

Abstract

The invention discloses a technology for planting vetiver grass for rice stem borer luring, pollutant intercepting and soil fixation in a paddy. According to the technology and method, the pesticide dosage and non-point source pollution of a paddy can be reduced, the vetiver grass serves as a luring plant for luring and killing rice stem borers, servers as a pollution runoff nutrient intercepting plant and is transplanted at the two sides of a paddy ditch or a non-aisle ridge or a corner land or a wet land, the line spacing is 30cm-40cm, and the planting spacing is 25cm-35cm. After the vetiver grass grows up to a clump, on one hand, the rice stem borers can be lured by the vetiver grass to lay eggs in a concentrated mode and is killed in a concentrated mode, so that the land pesticide using dosage is reduced and environment pollution is relieved; on the other hand, developed roots of the vetiver grass are used for fixing soil and nutrients flowing from a farmland are intercepted through the established vetiver grass ecological ditch or the established vetiver grass wet land, a water body is purified and the environment is protected. The technology for planting the vetiver grass for rice stem borer luring, pollutant intercepting and soil fixation in the paddy is applied to a rice production zone in the south and has the dual effects of soil fixation, pollution interception, vetiver grass luring and pesticide reduction.

Description

technical field [0001] The invention relates to the rice production pollution prevention and control technology in the field of planting industry and agricultural environment technology. Background technique [0002] Chemical fertilizers and pesticides are important materials for rice production and play an important role in increasing rice yields. However, the extensive use of chemical fertilizers and pesticides is one of the main causes of agricultural non-point source pollution in rice fields, especially N and pesticides. Farmland surface runoff, farmland drainage and underground seepage enter water bodies and directly cause water pollution. Vetiver belongs to Gramineae Cyangrass. It is a perennial herb with crude fibers. It is drought-resistant, barren-resistant, stain-resistant, and cold-resistant. It mainly reproduces by division (tiller reproduction). To keep the plants, we found in production that rice borers prefer to lay eggs on vetiver grass, which has an attract...
