Problems solved by technology

However, when encountering high temperature above 35°C, it will also have an adverse effect on the fertilization process, and the empty shell rate will increase greatly
Many studies have shown that when rice encounters high temperature during the flowering period, it hinders pollen maturation, anther cracking, pollen germination on the stigma, and pollen tube elongation. The resulting infertility is the most serious damage to rice. Sensitive period, especially high temperature stress on the day of flowering, can easily induce infertility of florets and cause fertilization disorders, seriously affecting seed setting rate and yield

Embodiment Construction

[0017] The present invention is described in further detail below:

[0018] A kind of planting method of preventing high temperature heat damage of rice of the present invention, concrete planting method is as follows:

[0019] 1) Variety selection: select rice varieties that are mid-maturing or partial-maturing, fast in heading and filling, and strong in high temperature resistance;

[0020] 2) Arrange the sowing date and cultivate drought-resistant and strong seedlings: reasonably arrange the suitable sowing date according to the growth period of the rice variety, properly control the amount of nitrogen fertilizer in fertilization, apply less available nitrogen fertilizer, and apply enough phosphorus and potassium fertilizer;

[0021] 3) Cultivation method: Early breeding and sparse sowing and early planting are adopted, wide and narrow rows are set in wide and narrow plants, and planted in staggered nests, and the seedlings are properly sown. When the seedling age is 3 to 4...

Abstract

The invention discloses a planting method for preventing high temperature hot damage of rice. The planting method is improved by measures such as variety selection, reasonable cultivation, installation of spray irrigation equipment and spraying of a self-made fertilizer. Under heading filling at high temperature of 35 DEG C on the planted rice, the yield is not affected basically.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a planting method for preventing high-temperature heat damage of rice. Background technique [0002] The Yangtze River Basin in my country is an important rice planting area, and a large part of the flowering and filling period of rice planted every year coincides with the high temperature season in midsummer. The period of high temperature coincides with the flowering and filling period of rice. The high temperature and heat damage often lead to high empty grain rate and decreased seed setting rate of rice, resulting in poor quality of rice, reduced yield and reduced benefit, affecting farmers' enthusiasm for production and rice production. negatively impact food security. [0003] The heat damage caused by high temperature to rice is closely related to the growth period of rice, that is to say, heat damage can only occur when the high temperature occurrence p...
