不同腐植酸土壤调理剂对西瓜生长的影响

Effects of Different Humic Acid Soil Conditioner on Watermelon Growth

为研究不同腐植酸土壤调理剂配方对西瓜生长的影响,以新蜜1号西瓜为试材,调查研究不同配方对西瓜生长及果实品质等各项指标的影响。结果表明,T5处理使坐果率提高了20.6个百分点,增产最为明显,增产21.7%;各土壤调理剂处理均能提高果实维生素C含量和降低总酸含量,以T6处理维生素C含量增加最多,增幅16.0%,其中仅T5处理提高了西瓜中心可溶性固形物含量。综合认为,参试腐植酸土壤调理剂配方具有提高西瓜产量和坐果率、调节生长和改善品质的作用,但是不同配方效果不同,尤以T5处理效果最好。

In order to study the effects of different humic acid soil conditioner formulations on watermelon growth,Xinmi No.1 watermelon was used as the test material to investigate the effects of different formulations on the growth and fruit quality of watermelon.The results showed that T5 treatment increased the fruit setting rate by 20.6 percentage points,and the yield increase was the most obvious with an increase of 21.7%.All soil conditioner treatments could increase the vitamin C content and reduce the total acid content of the fruit.The content of vitamin C of T6 treatment increased the most with an increase of 16%,and only T5 treatment increased the content of central soluble solid.It was concluded that the tested humic acid soil conditioner formulations had the effects of increasing watermelon yield and fruit setting rate,regulating growth and improving quality,but different formulations had different effects,and T5 treatment had the best effect.
