山葡萄不同时期施肥和不同施肥量对增产效果的研究
Effects of Applying Fertilizer at Different time and Differet Level on the Yield of Vitis.amurensis Rupr
摘要
Abstract
In order to research the effects of applying fertilizer at different time and different level on the yield of Vitis.amwensis Rupr. Main cultivars Shuanghong, Shuangyou, Zuoyouhong, Beibinghong, strain 2001-1-135 and 98-8-165. The results showed that the average yield per plant after fertilization increased by 27.3%. After organic fertilizers in fall, urea 45kg+superphosphate 22.5kg+ potassium sulfates 45kg per mu before flowering 7-10 days is the critical point of fertilization, fertilizer damage occurs 5 days after fertilization. High fruit setting rate, large ear appeared after organic fertilizers applied in fall, urea 15kg+superphosphate 7.5kg+ potassium sulfates 15kg per mu during rudiment, urea 20kg+superphosphate 10kg+ potassium sulfates 20kg per mu before flowering 7-10 days and diammonium phosphate 7.5kg+ potassium sulfates 15kg during fruit coloring. Yield increased 63%, it can be promoted in production with best fertilization ratio (N:P:K=l:0.5:l).关键词
