| 摘 要： | 为明确不同腐植酸复混肥施用量,对葡萄生长及土壤养分的影响,采取以二年生葡萄幼树进行盆栽试验。结果表明,与等养分无机化肥相比,腐植酸复合肥明显提高了葡萄植株对N、P、K肥的利用率,使土壤中的N素释放减缓,P的移动性和K的含量有较明显提高,并使土壤中有机质含量有增加的趋势。

| Abstract: | In this paper,the effects of different application rates of humic acid compound fertilizer(HA) on grape growth and soil nutrients of two-year old grape(Kyoho) were studied.The results showed that different application rates of humic acid compound fertilizer(HA) could affect the physiological activities and nutrients accumulation of grape.Compared with inorganic fertilizer,HA compound fertilizer could promote N,P and K uptake by grape.Through applying HA compound fertilizer,available N,available P and available K were greater than that applied with equal nutrient of inorganic fertilizer.The contents of organic material increased by 1.23%-3.08%. |
