Planting method for preventing and treating diseases and insect pests of organic rice

Abstract

The invention discloses a planting method for preventing and treating diseases and insect pests of organic rice. The method comprises the following steps of a, variety selection, wherein organic riceseeds are selected and automatically produced by an organic production unit or obtained from the market, it is required that the variety is successful in national investigation or market investigation, the seeds are good in quality, suitable for local ecological environment, high in disease and insect resistance and free of prohibited substance treatment, and the variety not subjected to an irradiation technology or a transgenic technology is selected; b, sowing and seedling raising, wherein a vegetable garden field or dry land loam which is fertile, leeward, sunny, good in drainage, few in weed, free of diseases and insects and faintly acid or neutral in soil and has convenient water sources is selected, furrowing is carried out on a seedbed according to the spacing of 1.8-2.0 m, and thefurrow face is 1.4-1.5 m wide. The method has the advantages that the disease and pest resistance of the rice population is improved through the methods of strong seedling cultivation, reasonable close planting, aerobic irrigation and the like; by means of reasonable water layer management and fertilizer application, and the planting yield of rice is guaranteed; the diseases and insect pests can be prevented in the rice planting process through a rice and duck co-growing method, the yield can be effectively improved, and the income is increased.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a planting method for preventing diseases and insect pests of organic rice. Background technique [0002] The so-called organic rice refers to the use of fertilizers, chemically synthesized growth regulators, pesticides, etc. that are harmful to the human body or pollute the environment in the process of planting and cultivating rice. The rice seeds planted are not from genetically modified, and the seeds follow natural The pollution-free planting method is obtained, and the natural law should not be destroyed when planting. It is best to combine planting and breeding, achieve recycling, and maintain the stability of the farmland ecosystem. [0003] Although organic rice has many benefits, and its selling price is one-fifth to one-half, or even more, than that of ordinary rice in the domestic and international markets, but at the same time, organic rice is more susceptible ...

Problems solved by technology

[0005] The above-mentioned patents use compound fertilizers for planting, and common insecticides are used for insecticide and sterilization, which cannot effectively control diseases and insect pests, and the yield of rice planted in this way is low, and the nutritional value is not high. Therefore, we need to further improve
