摘要
对贝达葡萄植株施用不同配比浓度沼液的结果表明:施沼液原液的植株各生长性状均好于其他处理,但由于施肥量较大,导致其营养生长明显,结实性状表现不理想;施用配比浓度25%沼液的植株各结实性状优良且种内差异较大,具有较大的良种选择空间,可改良遗传性状。
The test was different concentration ratio of biogas slurry on Beta grape .Through measuring growth traits, theseed traits and genetic traits of beta grape, the optimum concentration ratio ofbiogas slurry on Beta grape was scientific selected. The results showed that growth traits of beta grape fertilized by biogas slurry stoste were better than the other, but due to the fertilizationamount was larger, so growth characters were better than seed traits, seed traits were better and the internaldifferences were larger of beta on biogas slurry concentration of 25% , with a greater choice space of breeding, genetic traits could be improved.Biogas slurry as fertilizer applicating in grape cultivation, can significantly optimize the growth traits, genetic improvement of fruit, increase yield significantly, but qualitative and quantitative scientific fertilization should be advocated for reducing the cost and increasing economic benefits.
