试验证明,桑园间作大蒜和洋葱,对桑田产量没有影响,能提高经济效益30～50％。 桑园间作大蒜、洋葱,要根据树龄大小,桑条密度高低,桑行宽窄等条件,决定间作作物的占地面积。为确保桑树增产优势,只在宽行间作,保持窄行休闲,大蒜和洋葱的种植密度一般采用株行距10～12×15～20厘米种植,边际与桑树相距20～25厘米,以便进行管理。还可按苗蒜、苔蒜种植要 Experiments show that mulberry intercropping garlic and onions have no effect on the mulberry yield, can improve economic efficiency of 30 to 50%. Mulberry intercropping garlic, onions, according to the size of the tree, mulberry density, mulberry slender narrow and other conditions, to determine the intercrop area for crops. In order to ensure the superiority of mulberry yield, we only need to make narrow row leisure between wide rows. Planting density of garlic and onion is generally 10 ~ 12 × 15 ~ 20 cm. The margin is 20 ~ 25 cm apart from mulberry for management. Miao garlic can also be, moss garlic planting to
