不同种类有机肥对盆栽葡萄的生物学效应

为了探讨不同种类的有机肥对葡萄的生物学影响,利用盆栽方式研究了4种有机肥对赤霞珠葡萄生长量和根际微生物的作用。结果表明,施用有机肥明显提高根际土壤的放线菌和细菌含量,但对真菌含量增加不明显。施有机肥明显促进了新根的发生和生长,与对照相比各种肥料均显著增加了植株生物量及各器官的生长量。其中绿源有机肥成百倍增加了根际放线菌和细菌的数量,显著增加了新根数量,促进了枝干增粗,极显著增加了1、2年生枝条和褐色根的可溶性糖含量和淀粉含量;施用羊粪的效果次之;施用鸡粪显著促进植株生长,不利于可溶性糖和淀粉含量的积累,同时增加了土壤真菌数量;施用牛粪对微生物影响很小,但能促进生长。总体上看绿源肥效果最佳。

Biological Effects of 4 Organic Manures on Potted Grapevines

In order to discuss the biological effect on grape of different kinds of organic manures, we searched four organic manures for the affections of the growth and the microcosm around rhizine of ''Cabernet Sauvignon'' grapevine (Vitis Vinifera L.) potted. The results indicated that the amount of bacterium and actinomycets in soil around rhizine was distinctly increased by applying manures, but the increase of the amount of fungi is not marketable. Furthermore, all the manures promoted the development and growth of grape new roots clearly. It was found that various manures significantly increased the plant total weight and various organ weight contact to the control. Applying green manure increases the amount of bacterium and actinomycets in soil around rhizine hundreds of times, increases the number of new roots clearly, develops stem diameter, significantly raises the starch and soluble sugar content of transport root and 1,2- year-old branch. The effect of applying sheep manure was the second. While applying chook manure develops the growth of the grape, not good at the enhancement of the soluble sugar and starch content, and also enhances the amount of the fungi in soil. Applying dairy manure on the microsom is very little, but can enhance the growth of the grape. Overall, it could be concluded that green manure is the best.
