Cultivation method for high-yield rice

Abstract

The invention relates to a cultivation method for high-yield rice. The method comprises the following steps: 1) performing breeding, wherein breeding includes seed treatment, warm storage for accelerating germination and raising rice seedlings; 2) performing transplanting; and 3) performing field management. According to the method provided by the invention, seeds are soaked after Tomb Sweeping Day, dry straw is prepared, the seeds are stored in a warm environment, and the rice seedlings are raised, so that seeds can be saved, the production costs can be reduced, the survival rate of the riceseedlings can be guaranteed and the rice seedlings can be guaranteed to be neat. In the aspects of transplanting and field management, firstly, planting is performed in rows, the rice seedlings are transplanted thinly, so that the rice can play a certain photosynthesis role and be convenient to manage; secondly, a depth of irrigation and water discharge is determined according to a level of growthvigor of the seedlings; thirdly, a field is dried in the sun, so that heat of field soil can be improved, and the growth vigor of the seedlings can be promoted; fourthly, straw leaves can be tough and hard, diseases and pests can be not easy to cause, and the amount of pesticides can be reduced; and fifthly, ineffective tillering can be controlled. According to the method provided by the invention, the rice seedlings are thinly transplanted, a yield is high, 8004 clusters of rice seedlings are transplanted per square at most, and one rice seedling can grow four ears; and thin planting bringssufficient ventilation, sunlight irradiation force is strong, reasonable field drying and limited insect killing are combined, so that the diseases and the pests are basically not easy to cause.

Description

technical field [0001] The invention relates to rice planting, in particular to a method for cultivating high-yielding rice. Background technique [0002] Rice cultivation has a history of more than 7,000 years in my country, and my country has the habit of taking rice as a staple food. Traditional rice cultivation is mainly based on farmyard manure, without the use of chemical pesticides. With the growth of my country's population, the demand for food has also increased, and the issue of food safety has always been the top priority of the party and the country after liberation. In order to increase grain, the focus is on increasing the yield per unit area of ​​grain. On the one hand, new high-yield varieties are cultivated through breeding, and on the other hand, the yield per unit area is increased by researching new cultivation measures. With the advancement and development of society, the construction of roads, railways, and urban expansion in various places occupy lan...

Problems solved by technology

The emergence of hybrid rice has largely solved the problem of grain production, but the following problems still exist in the cultivation of hybrid rice: 1. The amount of seeds used is large, and one mu of land needs to use about 0.75 to 1 kg of seeds

3. The dense planting has poor sunlight and poor ventilation, so it is easy to be infected with pests and diseases, so the amount of pesticides is heavy, and the frequency of disease prevention is high. From seedling raising to harvesting, pests and diseases need to be prevented 6 times
