不同施肥灌溉方式对西瓜生长的影响

摘要

以新蜜一号西瓜为试验材料，通过对4种不同的灌溉施肥方式的试验，探讨了不同水肥配比对西瓜生长的影响。试验结果表明，作物的生长能在一定程度上改良土壤，处理4和处理2西瓜叶片的叶绿素含量比其他处理的要高，其硝酸还原酶的活性也与其他处理差异显著，处理3和处理4的西瓜产量和品质较其他处理好。%In the paper we studied the effects of four different irrigation and fertilization methods on the growth of watermelon cultivar Xinmi No.1. The results showed that the growing of watermelon could improve the soil in a certain extent. The chlorophyll content of treatment 4 and treatment 2 was higher than the other treatments', and the nitrate reeducate activity of treatment 4 and treatment 2 was significantly higher than the other treatments', while the yield and quality of treatment 3 and treatment 4 were better than those of the other treatments.
