High-yield cultivation method of japonica rice

Abstract

The invention discloses a high-yield cultivation method of japonica rice. The method comprises the following steps that japonica rice seeds are put into salt water to remove seeds floating on the water surface and then washed with clear water for use; the washed japonica rice seeds are put into clear water for soaking, fished out after soaking is completed and put into a sodium hypochlorite solution with a disinfectant for disinfection treatment, filtering is conducted to remove the sodium hypochlorite solution, and the japonica rice seeds are washed with clear water; the washed japonica riceseeds are soaked in water for germination acceleration treatment, then filtered and dried; the dried japonica rice seeds are planted in nutrient soil of a rice seedling raising tray in a greenhouse; when the japonica rice seeds grow to be at the leaf age of 3, seedlings are directly transplanted to a test field for normal management and growth. The high-yield cultivation method of the japonica rice has the advantages that by increasing the germination rate of the seeds and the survival rate of the japonica rice seedlings and preventing diseases and insect pests in the process of seedling production, the yield of the japonica rice is increased, and the quality of the japonica rice is improved.

Description

technical field [0001] The invention relates to the field of planting technology, in particular to a method for cultivating high-yield japonica rice. Background technique [0002] The fruit of rice is rice paddy, which is called brown rice after the chaff is removed, and rice can be obtained by grinding the rice bran layer off the brown rice. Nearly half of the world's population feeds on rice. In addition to being edible, rice can also be used to make wine and sugar. Rice husk and rice straw can be used as livestock feed. my country is a large agricultural country, and rice planting is the foundation of the national economy, which is of great significance. However, the small scale of traditional paddy field planting in our country has resulted in more investment, less income, and lower income from grain planting. The enthusiasm of the people for planting has dropped sharply, and the phenomenon of rural farmland abandonment has become more and more serious, endangering nati...

Problems solved by technology

However, the small scale of traditional paddy field planting in our country has resulted in more investment, less income, and lower income from grain planting. The enthusiasm of the people for planting has dropped sharply, and the phenomenon of rural farmland abandonment has become more and more serious, endangering national food security.

[0003] Due to the large population in our country and the decrease of arable land year by year, high-yield breeding has always been the primary goal of rice breeders. However, most of the existing rice planting techniques adopt rough planting methods, which result in low yield and poor quality. A large amount of chemical fertilizers are used in seedling fields, and the utilization rate of fertilizers is low, which leads to serious environmental pollution caused by excess fertilizers, and at the same time makes the chemical harmful components in rice exceed the standard, endangering human health
