Ecological control method for weeds on ridge of rice field

Abstract

The invention belongs to the technical field of rice planting, in particular to the field of ecology, and particularly relates to a control method for weeds on the ridge of a rice field. The ecological control method for the weeds on the ridge of the rice field is to apply paclobutrazol to the weeds on the ridge of the rice field. According to the method disclosed by the invention, the weeds on the ridge of the rice field can be kept in a dwarf state all the time, so that the weeds cannot scramble for a growth environmental space with rice to enable the rice to gain much more sunshine, and the aims of relieving damage caused by pests and diseases and increasing the yield are fulfilled; and furthermore, a good habitat environment can be supplied to natural enemies of rice pests, and the effect of reducing application of rice pesticides is achieved, so that a farmer can earn good ecological and economical benefits.

Description

technical field [0001] The invention belongs to the technical field of rice planting and the field of ecology, and in particular relates to a method for controlling weeds on paddy field ridges. Background technique [0002] Rice is the main food crop in the south. Farmers mainly use manual mowing or spraying glyphosate to remove weeds on the ridges of paddy fields. These two traditional methods have obvious shortcomings. Manual mowing costs a lot of labor. It didn't take long for it to grow again, and it had to be cut many times. The effect was not good. Spraying glyphosate was good for weed control, but it destroyed the ecological environment, affected the growth of rice to a certain extent, and caused yield loss. [0003] Paclobutrazol is a chemical agent, and its conventional use is to spray it with water on the seedlings to prevent the top growth advantage of the seedlings and promote the growth of side buds (tillers). The appearance of the seedlings is short and strong...
