聚丙烯酰胺型保水剂对西瓜产量和品质的影响

摘要

To expand the application scope of polyacrylamide,a field trial field was conducted to investigate the effects of polyacrylamide on the yield and quality of watermelon.Two treatments designed were polyacrylamide treatment （applying polyacrylamide at 37.5 kg/hm 2） and the control （no polyacrylamide）.The watermelon varieties involved were Jingxin No.2 and L600.It was found that the yields of Jinxin No.2 and L600 in the polyacrylamide treatment were 63.0 t/hm 2 and 85.8 t/hm 2,respectively,increased by 6.39% and 20.2%,as compared to the control.Applying the polyacrylamide did not affect the watermelon fruit quality.The economic benefits of applying polyacrylamide were 85.7 thousand Yuan for the Jinxin No.2 and 143 thousand Yuan for the L600,increased by 6.61% and 23.8%,respectively.In conclusion,the polyacrylamide had the wide application prospect because of achieving the effects of increasing yield and economic benefits in watermelon.%为了扩大保水剂在蔬菜上的应用范围,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63.0t/hm2和85.8t/hm2,分别比对照增产6.39%和20.2%。‘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%。施用保水剂显著提高了经济效益,而对西瓜品质影响很小。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。
