硝酸钾是钾肥的一个新型品种,应用于西瓜种植,增产效果明显优于氯化钾。 试验表明,西瓜施用硝酸钾能改善品质,中心糖度提高0.8度,边糖提高1.2度,瓜皮减薄0.07厘米,主蔓长度增加0.8～1米,增强分枝能力,提高坐果率11.7％～12.5％,与氯化钾相比,坐果率 Potassium nitrate is a new type of potash fertilizer, applied to watermelon cultivation, and its yield increase is obviously better than that of potassium chloride. Experiments show that watermelon potassium nitrate can improve the quality of the center of the sugar increased by 0.8 degrees, the side sugar increased by 1.2 degrees, melon thinning 0.07 cm, the main vine length increased by 0.8 to 1 meter, enhance the ability to branch and improve fruit set rate of 11.7% 12.5%, compared with potassium chloride, fruit set rate
