Cultivation Optimization for New Sweet Potato Variety,‘Longshu 13’
摘要
Abstract
For high yield cultivation of the edible sweet potatoes,‘Longshu 13’,an orthogonal experimentation was conducted.Yield affected by the planting density,transplanting time,vine cuttings and fertilization was investigated for the optimization.The results indicated that the planting density,transplanting time and vine cuttings had a very significant,while the fertilization a significant,effect on the yield of the sweet potatoes.The yield could be further improved by increasing the planting density from 40 005 to 49 995 plants ·hm-2 ,planting early,using the top vines,or applying 150 to 525 kg·hm-2 of compound fertilizer.On soils of moderate fertility,the sweet potatoes could attain a high yield with the optimized conditions of a planting density of 49 995 plants·hm-2 ,planting on July 18 (with a growth period of 133 days),using the top of vines for transplant,and applying a composite fertilizer at the rate of 525 kg·hm-2 .关键词
