桑园间作草莓是一种立体种植模式,根据各自生物学特性,不仅互不影响,而且又有相辅相成之效,可增加单位面积的经济效益,一般净增益700元左右。其栽培技术要点为: 一、合理施肥: 定植前一般每亩施粪肥30担、复合肥30公斤作基肥。翌年3月上旬和4月上旬每亩追施硫酸胺10公斤。二、适时定植: 桑树在4月下旬始展叶,5月中旬50％郁闭,郁闭期10天左右,伐条后即可透光。因此,10月上中旬定植为宜,每亩密度为4000—4500株。定植后灌一次定 Mulberry intercropping strawberry is a three-dimensional planting mode, according to their biological characteristics, not only do not affect each other, but also complement each other, can increase the economic benefits per unit area, the general net gain of 700 yuan. The cultivation techniques are as follows: First, the rational fertilization: Before planting, the general manure 30 acres per mu, 30 kilograms of compound fertilizer for the base fertilizer.
