摘 要:以速效氮肥分次施用的习惯施肥方式为对照,设置不同用量的包膜尿素和等量普通尿素一次性施用处理,研究不同用量控释氮肥对葡萄生育性状、产量和可溶性糖的影响。结果表明:施用控释肥对葡萄穗重、穗粒数、粒重等指标有一定影响,与习惯施肥处理相比,葡萄的可溶性糖有了明显提高。从产量结果看,施用一定量控释氮肥和速效氮肥一次性施用,与习惯施肥产量持平或显著提高,同时减少了氮素养分投入量和施用次数。综合来看,在当地试验条件下,以每667m2施氮24kg,其中控释氮14kg,速效氮10kg,做基肥一次施用的方式效果最好。Available nitrogen fertilizer application at different stages as the control treatment,different amount of coated urea and an equal amount of urea mixed one-time application were used to study the effect of different amount of controlled release nitrogen fertilizer on grape growing characteristics and yield.The results showed that the release fertilizers had some influence on the grape spike weight,grains per spike,grain weight and other indicators,compared with the control treatment,the sugar content of grapes had been significantly improved.From the yield results,a certain amount of controlled release fertilizer and urea one-time application was the same or significantly improved compared with the control treatment,and this method reduced the nitrogen nutrient inputs and the times number of application.Taken together,the best fertilization methods in local was application nitrogen fertilizer N 24 kg per 667 m2,which 14 kg controlled-release nitrogen and 10 kg available nitrogen as base fertilizer.
