摘要：

为了提升保水剂在蔬菜上的应用水平，以聚丙烯酰胺型保水剂和西瓜为对象，采用大田试验对比研究了聚丙烯酰胺型保水剂（PAM）和对照（不施保水剂CK）对西瓜产量、品质和经济效益的影响。结果表明：施用保水剂，‘京欣2号’和L600西瓜产量分别是63.0 t/hm2和85.8 t/hm2，分别比对照增产6.39%和20.2%；施用保水剂对西瓜品质影响很小；施用保水剂显著提高了经济效益，‘京欣2号’和L600每公顷可实现经济效益8.57万元和14.3万元，与对照相比分别增加6.61%和23.8%。聚丙烯酰胺型保水剂实现了在西瓜上的显著增产和增收，在蔬菜上应用具有广阔的前景。

Abstract:

To improve the applying level of polyacrylamide, field experiments were conducted to investigate the effects of polyacrylamide on yields and quality of watermelon. There were two treatments with PAM treatment (applying polyacrylamide of 37.5 kg/hm2) and CK treatment (no polyacrylamide).The varieties of watermelon were jingxin no.2 and L600. The results showed that yields of jinxin no.2 and L600 with applying polyacrylamide were 63.0 t/hm2 and 85.8 t/hm2 respectively, increased by 6.39% and 20.2% when compared to CK treatment. Applying polyacrylamide did not affected the watermelon fruit quality. The economic benefits of applying polyacrylamide were 85.7 and 143 thousand of jingxin no.2 and L600, which increased by 6.61% and 23.8% respectively when compared to CK treatment. In conclusion, the polyacrylamide has the widely application prospect because of achieving the effects of increasing product and economic gains in watermelon.
