Problems solved by technology

In the case that the natural growth conditions cannot be changed, the ability of the fabric to adapt to the adverse environment can be effectively enhanced by improving the resistance of the plant itself to the adversity, but there is currently no method to quickly improve the drought resistance of the plant

Abstract

The invention discloses a dry rice nursery cultivating method capable of improving rice drought resistance. By adopting the dry rice nursery method, the quality of rice seedlings can be improved, and the rice seedling raising cost is lowered; compared with a traditional rice seedling raising mode, more water resources are saved, the sowing quantity is decreased, and a good foundation can be laid for follow-up high-yield cultivation due to the high seedling harvesting amount. By adopting metal elements for configuring a drought resistant agent, the agent is sprayed at the right time, the rice drought resistance of rice seedlings can be effectively improved, the adopted raw materials of the drought resistant agent are cheap and easy to obtain, and the cost is low.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for raising rice seedlings under drought conditions for improving the drought-resistant performance of rice. Background technique [0002] Rice is one of the main food crops in my country. It has a large sowing area. It is generally cultivated in flooded lands in coastal plains, tidal deltas and river basins in tropical, subtropical and temperate regions. Its drought tolerance is between xerophytic plants and aquatic plants. between plants. Drought is one of the adversity stresses that plants suffer. The arid area on the earth accounts for more than half, while the arid and semi-arid soils in my country account for 51% of the total land area. At the same time, other arable lands often suffer from drought and reduce production. Every year the country loses more than 10 billion kilograms of grain due to drought, and the direct economic loss is huge. [0003] At pres...
