How to fertilize wax gourd effectively

Fertilization principles white gourd suitable for organic matter-rich sandy soil growth, fertilizer tolerance is not barren, nitrogen, phosphorus, potassium, calcium and other nutrients required comprehensive. Base fertilizer should be heavily applied and topdressing should be reasonable. Nutrient uptake was less at seedling stage, more at bolting stage, and most at flowering and fruiting stage, especially at early and middle stages of fruit development, and gradually decreased at late stage. Increasing N fertilizer, lengthening main stem and P and K fertilizer could delay senescence of early-maturing varieties, decrease female flower node position and increase single melon weight. Wax gourd base fertilizer should be applied with sufficient base fertilizer, generally 300~500 kg of refined commercial organic fertilizer per mu; if self-made organic fertilizer is used, the organic fertilizer should be fully decomposed, and the dosage should be increased, and 3000~5000 kg per mu should be applied. Organic fertilizer should be applied at the same time phosphorus and potassium fertilizer, diammonium phosphate, potassium chloride each 20 kg, phosphorus fertilizer should be mixed with organic fertilizer together with the application, can be adopted furrow or hole application. After topdressing and planting, topdressing 8 kg ammonium sulfate or 3 kg urea per mu. After sitting melon, urea 15kg and potassium sulfate 20kg per mu shall be applied. After that, 10 kg of diammonium phosphate was applied once or twice per mu.
