1. Selection and popularization of new high-quality rice varieties and new combinations. Promotion of key new rice varieties and new combinations based on Liaojing 294, Liaojing 371, 92-34, and Shennong 16 etc. 2. Honda farming and soil improvement technologies Change the traditional farming methods to less tillage, rotary tillage, and ploughing with water pressure. Corresponding methods for improving and fertilizing different types of paddy soils were adopted. 3, high-quality rice production field groups, individual growth and development control techniques to cultivate age-appropriate seedlings: including the selection of seeds, the implementation of a wide bed and dry nursery, the use of special non-woven cover to simplify labor-saving seedlings, with full nutrition strong agent preparation Nutrients for nursery soil; use Nutrient tablets, calcium plastic films, etc. as nutrient soil carriers; factory facilities for centralized breeding. Reasonable and sparse planting: specific indicators of reasonable and sparse planting due to characteristics of species characteristics, due to local characteristics, ecological climate, and management level; concrete forms can be used for spacing, sparse planting, and thinning or thinning; According to the outside temperature, the growth period of the variety, and the growth of the seedlings, the appropriate transplanting period should be determined. The transplanting method should be used for throwing and transplanting the seedlings. The transplanted rice should be transplanted in the conditional area and the seedlings should be timely transplanted in the shortest time. To Honda; 4, economic and rational fertilization technology to increase the quality of organic fertilizer: in order to improve soil organic matter content, enhance soil fertility, so that the soil structure is more loose, to ensure that 3000 kg of high-quality organic fertilizer applied per acre, including livestock manure, all kinds of tanning Piles of manure, rice straw, and mud in pits and mud pits. Fertilizer application to promote smooth fertilization. 5. Prevention of water pollution and optimization of irrigation technology Water pollution prevention: Select the land where the irrigation water is not contaminated, and implement the base; install a water purification device at the sewage outlet. Rational planning and construction and support for improvement of irrigation canal systems. 6. Principles for the comprehensive use of pesticides for preventing and controlling insecticide and herbicides: Do not use highly toxic and strong systemic drugs that contaminate rice. The final residue in rice should be kept to a minimum and must not be exceeded. Standards; not be used in the vicinity of cutting, use as much as possible to prevent and support pollution and reduce the degree of residue; adhere to the main prevention, to maximize the control and reduce the amount of pesticides; adhere to the early prevention of early treatment and early removal. 7. Specialized breeding of high-quality, high-yield new varieties, reasonable allocation, and development of multi-grade and high-quality rice. 8. High-efficiency cultivation techniques of high-quality rice crops and fruit replanting include rice-sunshine greenhouse vegetable multiple cropping technology; rice-mulching horse-old potato multiple cropping; rice-early spring robin multiple cropping; rice-west melon multiple cropping; rice-strawberry multiple cropping; rice field A variety of edible mushroom technology. 9. Rice-field broad-leaved seedlings and vegetable-growing techniques 10. Rice-field farming techniques include rice-fish farming techniques and rice-field duck-cultivation techniques.
