Precautions for planting:
1. Apply fertilizer according to the principle of "top priority should be stabilized before replenishment". Tiller fertilizer was applied in the early stage, nitrogen fertilizer was applied steadily at jointing stage, phosphorus and potassium fertilizer were applied more, and ear fertilizer was applied in the later stage. Nitrogen, phosphorus and potassium are used together;
2. In order to maintain the good taste of this variety, it is advisable to apply less nitrogen fertilizer and more organic fertilizer, especially try not to apply nitrogen fertilizer in the later stage. In the management of water slurry, we should master shallow water irrigation in the early stage to promote early development, put it aside in stages in the middle stage, strengthen the stems and roots, and alternate dry and wet in the later stage to live forever.
3. Soak seeds with chemicals before sowing to prevent seed-borne diseases such as bakanae disease and nematode disease, pay attention to the prevention and control of Laodelphax striatellus and thrips oryzae in seedling stage and field stage, and comprehensively prevent sheath blight and stem borer in the middle and late stage.
