In the process of rice planting, it is necessary to spray decomposed farmyard manure to promote plant growth, provide sufficient sunshine for rice, keep leaves green, and spray imidacloprid to eliminate pests.
The life of rice goes through two stages: vegetative growth and reproductive growth, and the shortest growth period of rice is three to four months. Among them, the vegetative growth period mainly includes seedling stage and tillering stage.
Seedling stage refers to the period from seed germination to seedling emergence. Tillering stage refers to seedling transplanting to jointing stage. After transplanting, the root system needs 5-7 days to be damaged, so that the aboveground part can resume growth and the root system can germinate new roots. This period is called turning green.
Rice planting time
The time of planting rice should be determined according to the environment and the growth cycle of rice. Generally speaking, rice in southern China is planted twice a year, which means it can be planted twice a year. But it depends on whether the rice field can withstand the growth of two seasons.
For example, rice planting in Northeast China can only be done once a year, which is different from the rice growth cycle in South China. Rice is widely cultivated in China. The sowing time and harvesting time will be different in different regions, and the taste of rice will be different because of the different planting environment.
