After transplanting, the application of "fertility fertilizer" can be applied with 10%-15% of rare human excrement. The second and third times were carried out 15-18 days and 25-28 days after transplanting, respectively, with 75-90 kg of urea per hectare and 60 kg of potassium chloride. The fourth time is carried out 37-40 days after transplanting, and 300-350 kg of potassium sulfate-containing compound fertilizer can be used per hm2. Open the hole at a distance of 15-20 cm from the base of the stem.
