Detailed Explanation of Key Points for Early-Stage Cultivation Management of Rice in Paddy Fields

As the saying goes“three parts planting, seven parts management”. After rice transplanting, it enters the paddy field management stage, and whether management techniques are in place has a great impact on per-unit yield. The core of early-stage cultivation management in paddy fields is“applying tillering fertilizer heavily and early”. This can promote early and rapid growth of seedlings, ensure early formation of effective tillers, and lay the foundation for high yield.

1. After planting, keep“one cun of water”in the field, which is beneficial for seedling greening.

2. 5-7 days after planting, apply“tillering fertilizer”heavily. For fields where seedling quality was poor at transplanting and seedling replacement occurred, it can be appropriately delayed.

3. “Tillering fertilizer”is mainly quick-acting fertilizer ammonium bicarbonate, and the application rate should account for 40-50% of the recommended amount from soil testing and formula fertilization. For general fields, ammonium bicarbonate 30-35 kg/mu, ordinary calcium superphosphate 30 kg/mu; for high-yield fields, ammonium bicarbonate 35-40 kg/mu, ordinary calcium superphosphate 30-35 kg/mu, applied mixed.

4. “Tillering fertilizer”adopts the method of mixed application of chemical fertilizer, insecticide, and herbicide, simultaneously achieving the purposes of fertilization, insect control, and weed control, and improving labor efficiency.
