Measures to promote the development of rice root system

1. Broadcast early at the right time. When the temperature is stable for 5 ℃, it begins to sow and raise seedlings. When the temperature is stable for 5 months, the seedlings are sterile for 5 months, and when the temperature is stable for 13 ℃, the seedlings are started to transplant. The seedlings are not planted for 6 months, and they are planted in the high yield period to gain accumulated temperature, which is beneficial to the development of roots.

2. Carefully prepare the land and create conditions. To do a good job of ploughing and rotary ploughing, the general ploughing depth is 20 cm, the rotary ploughing depth is 14 cm, and the ploughing or rotary ploughing depth is the same, so that there is no mud in an inch of water, creating conditions for root system development.

3. Strengthen management and promote development. First, seedling field management, good temperature control, reasonable watering, foliar spraying, prevention and control of bacterial wilt and bacterial wilt, weeding in seedling bed, cultivation of strong seedlings, shortening transplanting period, and promoting good root system development.

4. Honda management. Reasonable fertilization, the base fertilizer to achieve the combination of agricultural fertilizer, chemical fertilizer and biological fertilizer, the base fertilizer had better be organic fertilizer, the organic fertilizer had better be chicken manure, the amount of fertilizer should be about 1000 kg per mu, topdressing should be applied early, and the principle is to eat less and eat more. It can be divided into tiller fertilizer, panicle fertilizer and grain fertilizer. Scientific irrigation is also a good way to promote root development. Huadashui transplant seedlings, turn green in an inch of water, and irrigate in shallow water. During the whole growth period, dry and wet, intermittent irrigation is adopted to increase water temperature and promote root development. The water temperature of planting rice in well water can be increased by setting up sun pool, extending canal, day and night irrigation, film mulching of irrigation channel, atomization and shallow water irrigation to promote the good development of root system.

5. Disease prevention and pest control, healthy development. Do a good job in field prediction, comprehensive prevention and control of diseases and insect pests, and promote the healthy development of roots.
