不同种植模式和密度对籽用葫芦经济性状及产量的影响

Effect of Cultivation Patterns and Density on Economic Character and Yield of Zucchini

通过开展不同种植密度和种植模式对籽用葫芦产量的影响研究,结果表明,不同密度和种植模式对籽用葫芦病害的发生具有显著的影响,白粉病在低密度和垄作条件下不发病,高密度平作下,绵腐病发病严重;同一品种不同种植模式下,垄作种植较平作种植产量高,平均增产幅度在2.6%~9.0%;同一品种、同一种植模式,低密度和对照较高密度处理的产量高。因此,在平作种植条件下,高密度种植不适宜河套地区的籽用葫芦生产,若要提高种植密度必须改变种植模式。

The effects of different varieties of seed zucchini on yield under density treatment and planting mode were studied.The results showed that density treatment and planting mode had a significant influence on the occurrence of seed zucchini disease.Under the condition of low density and ridge cultivation,powdery mildew did not develop,high density was flat,and the incidence of cotton rot was serious.Under different planting patterns of the same spe⁃cies,the production of ridge planting is higher than that of flat planting,yield change between2.6%-9.0%;The same planting pattern of the same species,different density treatment,low density and control of higher density treatment yield.At present,under normal planting conditions,high-density cultivation is not suitable for the production of seed zucchini in this area.To increase the planting density,it is necessary to change the planting pattern.
