High-yield planting method for super hybrid indica type rice in high-latitude saline-alkali soil

Abstract

The invention relates to a high-yield planting method for super hybrid indica type rice in high-latitude saline-alkali soil and belongs to the technical field of hybrid rice planting methods. The method solves the problem that the hybrid indica type rice can not be cultured in the high-latitude saline-alkali soil through the hybrid rice technology. The method comprises the steps of management during the seedling cultivation stage, wherein settlement of a seedling bed, seed soaking, seeding, ventilating, temperature managing, water managing during the seedling stage, fertilizer managing during the seedling stage and pest and disease damage managing are carried out; management during the rice seedling transplanting stage, wherein soil leveling, alkali washing, alkali pressing, seedling transplanting, water managing, fertilizer managing and pest and disease damage prevention and cure are carried out; management during the development stage, wherein water managing, fertilizer managing and pest and disease damage managing are carried out, a method of combining dry rice nursery and an arched shed is adopted, water is managed with the standard of improving the vitality of roots, irrigation and drainage of the water in the whole field are achieved, fine plowing and managing are carried out, and fertilizer management is strengthened. The cultivation method for the hybrid indica type rice in the high-latitude saline-alkali soil is innovated, the hybrid indica type rice in the south is introduced into the northern high-latitude area to be planted, and therefore the purpose of the high yield of the hybrid indica type rice in the high-latitude saline-alkali soil can be achieved.

Description

technical field [0001] The invention relates to a high-yield planting method of super hybrid indica rice in high-latitude saline-alkali land, and belongs to the technical field of hybrid rice planting methods. Background technique [0002] The current hybrid rice has the advantages of vigorous growth, well-developed root system, large ears and many grains, and strong stress resistance. Heterosis can be used to improve the yield and quality of rice. In the prior art, the hybrid rice planting method has the following defects: (1) the existing hybrid rice planting is mainly aimed at the middle and lower reaches of the Yangtze River, and there is no planting technology for rice at high latitudes (35° north latitude-38° north latitude); (2) The technology of planting hybrid rice in high-latitude saline-alkali land (with a salt content of 3‰-5‰) is still technically blank; (3) Rice planted in high-latitude saline-alkali land cannot achieve high-yield purposes.
