硫酸锌袋控缓释对桃幼树锌素营养状况的影响
Effects of Bag-controlled Release Zinc Sulfate Fertilizer on Zinc Nutritional Status of Young Peach Trees
摘要
Abstract
Bag controlled - release fertilizer is a new type designed according to the big individual volume of fruit trees. It uses controlled - bag to control the release of nutrients. The bag controlled — release fertilizer designed with five - line micro hole and 20 g zinc sulfate every bag was studied in peach orchard. The results showed that the nutrient release concentration of bag controlled - release zinc sulfate fertilizer was above 80% in 105 days and could satisfy the demand of zinc nutrient for peach all over one growth season. Compared with the fertilizer treatments spreading none and two times D ( ZnS04 40 g per tree) 、E (ZnSO4 60 g per tree) and F (ZnSO4 80 g per tree) in orchard respectively, the zinc concentration of soil in root area and leaves were improved and kept stable by bag controlled - release treatments. The N, P and K concentration and Pn of leaves were all higher. The experimental results of A (2 bags per tree) 、B (3 bags per tree) and C (4 bags per tree) had no much differences.关键词
