【摘要】 为探索山丘薄地苹果树的有效增产措施,1989～1993年在新密市牛店乡的花家店小流域建立了3hm~2苹果丰产试验园.经5年试验,初步探索出了一套切实可行的增产措施,明显提高了果品产量及质量,与对照区相比,1994年、1995年、1996年苹果增产幅度分别为150%、220%及212%.其主要增产措施是:以保水增肥为中心,利用秸秆、杂草进行果园常年覆盖或春夏覆盖秋后掩埋覆草,并结合山地果树生长特点进行科学修剪.更多还原

【Abstract】 To probe into measures to effectively increase apple yield in sterile hillside, 3 ha of apple orchard for high yield experiment was set up in Huajiadian small watershed, Niudian Town of Xinmi City in 1989. Five years experiment preliminarily probed into a set of feasible measures which obviously enhanced yield and quality of apple. Contrasted with CK in 1994, 1995 and 1996, the apple yield increased by 150% , 220% and 212% separately. The main measures included covering land surface with stalks and weeds all the year round, or covering land surface in the spring and summer and burying straws and weeds after the autumn by taking water-retaining and fertilizer-increasing as center; conducting scientific pruning in accordance with growing features of hillside orchard.更多还原
