Double cropping super rice high-yield cultivation method

Abstract

The invention belongs to the field of super rice cultivation and discloses a double cropping super rice high-yield cultivation method. The double cropping super rice high-yield cultivation method comprises selecting planting fields, and ploughing and sterilizing the fields; spraying lime and special farmyard manure onto the fields; determining a species to be cultivated, and breeding rice seedlings; steeping the fields and applying base fertilizer; after the rice seedlings are transplanted, ensuring sufficient water for seedling reviving; applying weeding fertilizer; during a tillering stage,mainly performing moisture management, and during young ear formation and heading-flowering stages, performing shallow water irrigation. According to double cropping super rice high-yield cultivationmethod, the applied fertilizer application method saves processes of three fertilizer application and three pesticide application; the double cropping super rice high-yield cultivation method is simple, concise, precise in fertilizer and pesticide application and simple in operation and is a concise cultivation technique; during cultivation of the rice seedlings, bactericides are sprayed onto thesurface of nutrient soil to effectively improve the sterilizing effects and create a good environment for rice growth; rice seeds are soaked into dilute saline and then into bactericides to thoroughlykilling carried bacteria, moulds and the like and accordingly to improve the sprouting rate and the strong sprout rate of the rice seeds.

Description

technical field [0001] The invention belongs to the technical field of super rice cultivation, and in particular relates to a super-high-yield cultivation method for double-cropping super 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. Originally produced in China and India, rice was planted in the Yangtze River Basin of China 7,000 years ago (according to the carbonized rice discovered by archaeologists, the history of rice cultivation can be traced back to 10,000 years ago). Rice can be divided into indica rice and japonica rice, early rice and middle and late rice, sticky rice and glutinous rice according to morphological characteristics, cultivation season and endosperm starch composition. There are other classifications, which are divided into paddy field rice and floating rice according to whether it is ...

AI Technical Summary

Problems solved by technology

[0004] In the current rice cultivation process, there are many times of fertilization and drug use, many varieties, complicated operations for farmers, high labor costs, and high costs, which are difficult for farmers to accept.

[0005] In the process of rice seedling cultivation, bacteria are likely to be produced and affect the germination rate of rice seeds; the water demand is large, and rotten roots and water waste are prone to occur
