采用地下施草法与地面覆草法对比其改良土壤、促进果树生根结果的效益,地下施草法较地面覆草法增根106条,土壤有机质增加0.64％,容重减少0.28g/cm~3,空隙度增加11.7％,根系主要分布层土壤不板结,使果品增产增收,明显提高果园的经济效益,在不增加投资的情况下,每公顷每年可增加产值2722元。
Compared with the ground mulching method, the underground grass mulching method and the ground mulching mulching method were compared to improve the soil and promote the rooting result of the fruit tree. The underground grass mulch method increased 106 roots compared with the ground mulching method, the soil organic matter increased 0.64% and the bulk density decreased 0.28g / cm ~ 3 , Porosity increased by 11.7%, the root distribution of the main soil layer does not form a knot, so that fruit production and income, significantly increase the economic benefits of orchards, without increasing investment, each hectare can increase the output value of 2722 yuan per year.
