6%抗坏血酸水剂在西瓜和甜瓜上的施用

Application of 6% Ascorbic Acid WA in Watermelon and Melon

为了研究6％抗坏血酸水剂对温室大棚西瓜和甜瓜的增产效果，于2007年进行了试验。结果表明：6％抗坏血酸水剂1：1500～2500倍液茎叶喷雾3次，喷液量600-750kg／hm^2，平均增产10％～30％，处理区较对照区瓜皮薄、纤维少、肉质细嫩、味甜爽口，早成熟547d。建议大面积推广应用。

The different concentration of 6 % ascorbic acid WA was sprayed to study the effect on yield of watermelon and melon in the greenhouse. The results show that the yield of watermelon and melon spraying 2-3 times on stems and leaves with 6% ascorbic acid WA at a dosage of 6004700 kg/hm^2 （concentration of 1 ： 1500-2500）increases by 10%-30%. The quality and harvest time of watermelon and melon treated with 6 % ascorbic acid WA is better and 5-7 d early compared with CK. Therefore, 6% ascorbic acid WA should be applied in production of watermelon and melon on a large scale.
