桃树在果实生长期,对磷肥、钾肥较为敏感。而一般果园只注重氮肥的使用,往往忽视磷钾肥的合理使用。叶面喷布磷酸二氢钾(KH_2PO_4)能及时满足果实生长期对磷钾肥的需要,有利于桃果实的生长,增加可溶性固形物的含量,使桃果实风味浓,色泽艳丽、品质好。一、试材与方法本试验在天津市西郊区付村乡小南河林业队桃园进行。品种是大久保,树龄为八年生。株行距5×6米,面积为六十亩。八个台田,每台田四行,行向为南北行。试验分四
Peach trees in the fruit growing season, more sensitive to phosphate fertilizer and potassium fertilizer. The general orchard only focus on the use of nitrogen fertilizer, phosphorus and potassium are often ignored the rational use. Foliar spraying potassium dihydrogen phosphate (KH 2 PO 4) can satisfy the need of P and K in fruit growth in time, is conducive to the growth of peach fruit, and increase the content of soluble solids, making peach fruit rich in flavor, gorgeous color and good in quality. First, the test materials and methods The experiment in the western suburbs of Tianjin Municipality to pay the village of small southern forestry team Taoyuan. Variety is Okubo, tree age of eight years. Plant spacing 5 × 6 meters, an area of 60 acres. Eight Taitian, four lines per field, line to north and south. Test four points
