通过不同品种分期种植采摘试验和不同品种、密度、施肥三因素随机区组试验结果表明,嫩梢菜用甘薯周年生产以一年种植二茬为宜,分别于6月上中旬和10月中下旬种植, 后者采用大棚设施栽培;最佳的品种,密度和施肥方案为:品种用福薯7-6,种植密度选株行距15cm×20cm,施肥选基肥每667m2用复合肥29kg、追肥每667m2用尿素11kg,或基肥每667m2用人粪尿1778kg、追肥每667m2用人粪尿889kg按1:1掺水浇施,每隔7～14d追肥一次。 According to the randomized block test of three factors of different varieties, densities and fertilizations, the results showed that the annual production of Sweet Potato with sweet potato was suitable for planting one crop a year, respectively in the middle of June and mid-to-late of October The latter was cultivated in greenhouse facilities. The best varieties, densities and fertilization schemes were: varieties with sweet potato 7-6, planting density 15cm × 20cm, fertilization base fertilizer with compound fertilizer 697m2, dressing 667m2 With urea 11kg, or base fertilizer per 667m2 with human waste 1778kg, top dressing per 667m2 with human waste 889kg by 1: 1 water pouring facilities, dressing every 7 ~ 14d time.
