Healthy rice cultivation method based on whole-process green pest control

Abstract

The invention discloses a healthy rice cultivation method based on whole-process green pest control. The healthy rice cultivation method specifically comprises the following steps that S1, fertilizersare reduced for controlling pests, specifically, the base fertilizers are applied during ploughing, 1000 kg of sheep manure and 25-30 kg of controlled release compound fertilizers are applied per mu,and topdressing is not carried out any more in the whole process; S2, the variety is selected, and specifically, the high-quality resistant rice variety is selected; S3, seedling raising, machine transplanting and thin planting are carried out, specifically, centralized seedling raising is carried out through a seedling raising substrate tray stacking dark germination method on May 10th-15th; a biodegradable black film is covered while machine transplanting is carried out, and no herbicide is used in the whole later period; and S4, green prevention and control are applied, specifically, vetiver grass is planted; nectariferous plants are planted; and weeds are reserved on ridges. According to the healthy rice cultivation method, the problems of difficult weeding, high labor consumption andthe like are solved at one time by applying machine transplanting and black film grass shielding, and especially, the resistant weeds are weeded; the sheep manure and the controlled release fertilizers are applied at one time during ploughing, so that the labor cost is further reduced, and the soil quality and the rice quality are improved; and comprehensive measures such as wide-row planting, and green prevention and control technologies are applied, and no chemical pesticide is used in the whole process.

Description

Technical field[0001]The invention relates to the technical field of rice planting, in particular to a healthy rice cultivation method based on whole-process green damage control.Background technique[0002]At present, two methods of machine planting and direct seeding are mainly used in rice planting. Direct seeding of late rice saves time and effort, has a short growth period, is difficult to align the seedlings, is prone to lodging, and yields unstable. Light, anti-lodging, complicated process. In terms of cultivation and management, farmers apply chemical fertilizers and chemical control of plant diseases, insects and weeds. The frequency of chemical fertilizer application is generally 2 times or more, and chemical control of plant diseases, insects and weeds is generally 5 times or more. 3 times and above). These will have a greater impact on rice quality and ecological environment[0003]The existing rice planting technology has the following problems:[0004]1. Pesticide residues; ...

AI Technical Summary

Problems solved by technology

[0004] 1. Pesticide residues; the existing planting technology requires 5 or more times of chemical control of pests and weeds, especially herbicide residues are more serious

[0005] 2. The quality of rice is not high; traditionally planted rice does not use organic fertilizers such as sheep manure, and the quality of rice is poor

[0006] 3. The labor cost is high; the number of chemical fertilizers used in the whole growth period of rice is more than 7 times, and the labor cost is relatively high
