Key points of rice cultivation and management in early field
As the saying goes, "three points are divided into seven parts". After rice transplanting, it enters the stage of field management, whether the management technology is in place or not has a great impact on the per unit yield. The core of cultivation management in the early stage of field is "re-application of tiller fertilizer as early as possible". This can promote the early growth and rapid development of seedlings, ensure the formation of effective tillers as early as possible, and lay the foundation for high yield.
1. Keeping "inch water" in the field after planting is beneficial to the rejuvenation of seedlings.
two。 7 days after planting, "tiller fertilizer" was applied again. For the poor quality of seedlings when transplanting, the field where the seedlings are replaced can be postponed appropriately.
3. "Tillering fertilizer" is mainly the application of quick-acting fertilizer ammonium bicarbonate, and the application amount should account for 40% of the recommended amount of soil testing formula. In general, ammonium bicarbonate is 35 kg / mu and calcium bicarbonate is 30 kg / mu, while in high-yield fields, ammonium bicarbonate 35 kg / mu and calcium bicarbonate 35 kg / mu are mixed.
4. "Tillering fertilizer" adopts the method of mixed application of chemical fertilizer, insecticide and herbicide to achieve the purpose of fertilization, insecticide and weeding at the same time, and improve labor efficiency.
