A cultivation method that does not use pesticides to weed and eliminate weeds in rice fields

Abstract

A cultivation method free of pesticide weeding and weed in a field includes the following steps that in land preparation, multiple gullies are dug in the common paddy field, where the depth of the gullies is 20 cm-35 cm, the width of the gullies is 30 cm-55 cm, root-promoting seedling culture fertilizer is mixed with digging soil to form fertilizer soil, the fertilizer soil is stacked on soil between the gullies to form long banks, and the width of the long banks is 15 cm-30 cm; in planting, according to different densities, appropriate adjustment is made for planting on the long banks; in theprocess of making sedum aizoon and mud slurry, sedum aizoon and muddy water are beaten into the sedum aizoon and mud slurry through a beating machine; in irrigation, after rice seedling transplanting, the gullies are irrigated with water, seedlings are protected with deep water for 2-3 days, and the depth of the water is 20 cm-35 cm, in the heading period, roots of the seedlings are immerged withwater by 20 cm-30 cm, after full heading, intermittent dryness and wetness are performed, and after the period of yellow ripeness, the water is withdrawn; in harvesting, after maturing, harvesting and threshing are performed, and finally rice is stored. The cultivation method has the advantages that production is increased, there is no lodging, and the quality of the rice is excellent; The cultivation method is large in market capacity and broad in prospect and has great market value and social value.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a cultivation method without using pesticides for weeding and weed-free rice fields. Background technique [0002] The control methods of farmland weeds mainly include artificial control, chemical control, mechanical control and other methods. At present, most of the weeds are weeded by spraying herbicides in order to save manpower and material resources. According to statistics, there are more than 300 kinds of chemical herbicides at home and abroad, and different formulations are processed, which can be used to weed almost all food crops and economic crops. According to reports by the World Health Organization and the United Nations Environment Program, more than 1 million people are poisoned by herbicides every year in the world, of which 100,000 people die. The situation is even more serious in developing countries. There are nearly one million herbicide poi...
