Description

technical field

[0001] The invention belongs to the field of crop production and relates to a rice drought alleviating agent. Background technique

[0002] Double-cropping rice is the main planting mode of rice in southern my country. Due to two crops a year, the total output of double-cropping rice is 900 kg / mu, and the high-yield field reaches 1300 kg / mu, which is an average increase of more than 60% compared with one-cropping rice. my country's double-cropping rice The planting areas are mainly distributed in 10 provinces including Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Hainan, Yunnan, and Fujian, with a total area of ​​10 million hm 2 Left and right, double-cropping rice production has made an important contribution to solving the problem of food security in southern my country where there are many people and little land. The double-cropping rice area is traditionally a high-water area with large precipitation in the previous year. However, due to th...
