Abstract

The invention relates to the technical field of agricultural cultivation, in particular to an early and medium maturing rice planting method. Rice is generally planted in southern China, and rice planted in northern China is poor in disease resistance and low in head rice rate. The early and medium maturing rice planting method includes: 1) rice breeding, to be specific, planting a plurality of individual plants 'Qiuyou 88' in a cultivation rice field, and selecting a prominent strain for generation-adding breeding; 2) planting the bred rice; 3) fertilizing in a whole growth period; 4) retaining water in a tillering stage, retaining water from ear development to an earing stage, controlling water from a tillering termination stage to an ear differentiation starting stage, and performing dry and wet combined water control in a grain-filling stage; 5) spraying isoprothiolane in the middle of July, and spraying isoprothiolane after earing. High disease resistance and high rice rate are realized.

Description

technical field [0001] The present application relates to the technical field of agricultural cultivation, in particular to a method for planting early and mid-maturing rice. Background technique [0002] Rice is a kind of herbaceous Oryza genus, which belongs to cereals, and it is also the most important and oldest kind of food in Oryza genus, which is different from upland rice. Native to China and India, rice was grown in the Yangtze River Basin in China 7,000 years ago. Rice is divided into indica rice and japonica rice, early rice and mid-late rice according to rice type, glutinous rice and non-glutinous rice. There are other classifications, according to whether soilless cultivation is divided into paddy field rice and floating rice; according to the life cycle, it is divided into seasonal rice and "lazy rice" (regeneration rice); according to height, it is divided into ordinary rice and giant rice of about 2 meters. Rice; according to salt tolerance, it can be divid...
