摘要
对酿酒葡萄栽培进行N、P、K不同配方、不同施肥量试验,研究其与酿酒葡萄生长量、产量、品质的关系,结果表明:沙漠边缘地区酿酒葡萄N、P、K最佳配方为4∶2∶5,较适宜的施肥量为3年生株施0 3kg,4年生株施0 6kg。科学施肥是实现酿酒葡萄早期优质丰产和提高经济效益的有效途径。
This experiment has studied the relations of increment, yield, quality of grape and different fertilizer element and different quantity fertilizer.The study showed that it is a efficient way to attain early abundant yield and enhance economic effect by scientifically using fertilizer, The best fertilizer mixture ratio of N, P, K was 4∶2∶5, Rational quantities of fertilizer as follow: A tree aged three years needs 0.3 kg, aged four years need 0.6 kg.\;
