Embodiment 1

[0024] A method for planting high-yield rice in karst areas, including the following steps:

[0025] (1) Seed treatment: Dry the rice seeds in the sun for 1-2 days, soak them in the seed soaking solution for 30-40 minutes, remove them, and accelerate germination;

[0026] (2) Sowing: After pouring the seedling substrate thoroughly with water, sprinkle a layer of nutrients evenly, and then press the rice seed after accelerating germination to 1-1.2kg / 25m 2 Sow the seedlings on the seedling substrate, and then cover the arch frame with a layer of film to cultivate the seedlings;

[0027] (3) Seedling management: when the seedlings grow to 2.5 to 3.5 leaves, remove the film and spray water-soluble fertilizer once; 5 days before transplanting the seedlings, spray water-soluble fertilizer once;

[0028] (4) Transplanting: After applying antibacterial base fertilizer in the rice field, deep plough to a depth of 30cm, and cut seedlings at a row spacing of 9 inches × 6 inches, planting about 1...

Abstract

The invention belongs to the technical field of rice and particularly relates to a planting method for high-yield rice in the karst region. The method comprises the steps of seed treatment; sowing; seedling management; transplantation; field management; prevention and control over the diseases and pests. According to the method, through combination treatment of seed soaking treatment, seedling raising and application of an antibacterial base fertilizer, the disease and pest resistance of the rice is enhanced, and the occurrence rate of the diseases and pests in the rice planting process is lowered; through reasonable fertilization management, the setting percentage and grain weight of the rice are increased, and the yield of the rice is increased.

Description

Technical field [0001] The invention belongs to the field of rice technology, in particular to a method for planting high-yield rice in karst areas. Background technique [0002] Rice is an important food crop for human beings. About 50% of the world's population feed on rice as the staple food. In Asia, the rice-based population accounts for about 95% of the total population in Asia. In recent years, with the increase of population and the sharp decrease of available land, our country is facing the pressure of food demand. Therefore, the research on rice breeding and cultivation for super-high-yield has been paid much attention. It has always been the focus of agricultural research to maximize the genetic potential of crop varieties and improve cultivation management techniques. Southwest Guizhou is one of the main rice producing areas in Guizhou Province. Southwest Guizhou is a karst landform, dominated by mountains and hills, with complex terrain, lack of scientific plantin...
