Abstract

The invention provides a method for high-biomass lodging-resistant cultivation of rice. The method comprises the steps of selecting improved varieties of rice, cultivating strong seedlings, timely transplanting the seedlings, reasonably applying fertilizer, performing moisture management, performing disease and pest control, and performing promotion and restraint combination and biochemical regulation. According to the method for high-biomass lodging-resistant cultivation of rice, the rice is resistant to lodging while high biomass is achieved.

Description

technical field [0001] The invention belongs to the field of crop planting, and in particular relates to a method for cultivating rice with high biomass and resistance to lodging. Background technique [0002] Rice is an important food crop for human beings. Two-thirds of the population in China depend on rice as a staple food. Achieving ultra-high yields of rice is of great significance to ensuring food security and promoting social stability. Over the past half a century, the improvement of rice yield per unit area in my country has always been accompanied by the improvement of plant type (plant height), and has experienced the process of "high stalks become dwarf stalks, and dwarf stalks become semi-dwarf stalks". Furthermore, Academician Yuan Longping proposed that in order to obtain higher yields, plant type improvement needs to "change from semi-dwarf to half-high", that is, the plant height should develop from a semi-dwarf of about 100 cm to a half-high of 120 cm to 1...
