用叶绿康球肥在失绿桃树上进行大田对比试验 ,通过田间调查和叶片分析 ,研究了球肥对桃树叶片的复绿效果对叶内矿质营养元素的影响及增产效果。结果表明 :施用球肥可使桃树叶片失绿程度降低 2～ 3级 ,百叶重明显增加 ,单株产量提高 56%～ 89% ,全铁和活性铁含量提高 1 8.7%～ 1 9.5% ,可降低叶片中 N,P,K,Cu和 Zn的含量 ,使这些营养元素与铁的拮抗作用减弱
YeLvKang fertilizers were used to conduct field experiments on peach green peach trees. Field investigation and leaf analysis were conducted to study the effect of pearl fertilizer on the nutrient elements in leaves and the effect of yield increase. The results showed that the application of ball fertilizer could reduce the loss of peach leaf from 2 to 3, the leaf weight increased obviously, yield per plant increased 56% ~ 89%, total iron and active iron content increased by 1 8.7% ~ 1 9.5% Can reduce the content of N, P, K, Cu and Zn in leaves, and weaken the antagonism between these nutrients and iron
