2024-11-25

Fertilization management is the key link to improve the yield and quality of rice cultivation, and reasonable fertilization can promote the growth of rice and improve the ability of resistance to stress.
Application of 1. Base Fertilizer
Base fertilizer is the most important fertilizer in the early stage of rice growth. It is recommended to apply 30-40kg compound fertilizer (15-15-15), 2kg silicon fertilizer and 1kg zinc fertilizer per mu. In the application, the amount of fertilizer should be adjusted according to the soil fertility, and the base fertilizer can be increased in the field with low fertility.
Application of 2. Tillering Fertilizer
Tillering stage is the key stage of rice growth. Tillering fertilizer should be applied after the rice is turning green. It is recommended to apply about 10kg of urea (46%) per mu. For fields with weak seedling condition or late planting, the application amount of tillering fertilizer can be increased appropriately to help rice resume growth as soon as possible and increase the number of tillers. However, it should be noted that excessive application of nitrogen fertilizer can lead to excessive growth and increase the risk of pests and diseases.
3. ear fertilizer
Reasonable application of nitrogen, phosphorus and potassium can promote the development of spike, increase the number of grains and increase the grain weight. Attention should be paid to controlling the amount of nitrogen fertilizer, increasing the application of potassium fertilizer, and appropriately supplementing silicon fertilizer. It is recommended to apply about 5kg of urea, 10kg of potassium fertilizer and 2kg of silicon fertilizer per mu. It can enhance the ability of rice to resist lodging, promote the maturity of grain, and improve the yield and quality of rice.
4. fertilizer
Rice grain filling period generally do not supplement nitrogen fertilizer, can be appropriate to supplement the application of green protection, potassium dihydrogen phosphate and other foliar spraying. If the rice leaves early senescence can be appropriate foliar spraying appropriate amount of nitrogen fertilizer.
