Question: The reader with the phone number 6259 is asking how to improve the quality of the watermelon?
Li Junfa A: To improve the quality of watermelon, the following two methods can be used:
Scientific fertilizer: The demand for three elements of watermelon is ranked as potassium, nitrogen, and phosphorus according to the order of the height of the watermelon. Among them, potassium has a great influence on the quality of the watermelon, so the fertilizer should be dominated by farmyard fertilizers. Watermelon avoid chlorine, can not be applied ammonium chloride, potassium chloride and other chloride fertilizers. Such as 50 kg cake fertilizer Mushi, can significantly improve the quality of watermelon. In addition, the main period for ensuring the effect of foliar fertilizers on the quality of watermelons is 10 to 15 days before harvesting. At this time, the roots have already begun to age. In addition, pests and diseases damage, the leaves are yellow and fall off, the photosynthetic area is reduced, and sugar is reduced. The accumulation has a great influence. Therefore, in addition to the application of base fertilizers, especially fertilizers with long-lasting fertilizer, it is also necessary to cooperate with foliar spray fertilizer to actively prevent and treat plant diseases and insect pests and prevent premature plant failure.
Reasonable irrigation: Watermelon irrigation should be performed timely in order to increase yield in the early stage of watermelon growth, but in the later period, especially in the week prior to harvesting, water must be strictly controlled. At this time, the following rain should be promptly drained. Excessive moisture will not only greatly reduce the sweetness of the watermelon, but it will also cause cracking of the melon.
