≥20%) is favored by farmers in rice-growing areas of South China. The field demonstration experiment proved that the organic and inorganic compound fertilizer of Runtian Company was used in early rice, and the number of seedlings at tillering stage was small and the leaf color was light. Leaf color darkened at booting stage; Heading early and orderly; The mature stage is characterized by big panicle and luxuriant leaves; Strong lodging resistance.
First, the main points of tillering stage management
1. Before transplanting, according to the soil fertility, evenly spread 60-80 kilograms of organic and inorganic compound fertilizer per mu, and then evenly plough the fields.
2. Age-appropriate transplanting: Early rice seedlings are 25-30 days old.
3. Reasonable close planting: hybrid rice per hole 1.6- 1.8 million plants, conventional rice per hole 3-4 plants.
4. Shallow water tillering: after turning green, apply herbicides. When the number of seedlings in the whole field reaches 80% of the target number of ears, lightly air the field.
Second, the key points of young spike differentiation management
1, after transplanting 15 days, evenly spread 50-60 kg of organic and inorganic compound fertilizer in Runtian per mu.
2. Stop the dry field at the second leaf heading stage, and then keep the water layer until heading.
3. Pay attention to control rice leaf roller, rice planthopper and sheath blight once 40-50 days after transplanting.
Three. Key points of management during grouting and filling period
1, after transplanting 15 days, evenly spread high-quality urea 10 kg per mu.
2. Intermittent oral drugs: intermittent spraying to control rice blast, sheath blight and rice leaf roller.
3. Dry, wet, wet, rooting, leaf protection and water cutting should not be done too early about 7 days before harvesting.
