1 果薯用地的合理分配根据果树树龄和生长势合理安排果薯用地比例。以5m×3m规格梨树为例:新植果园1~3年果树行间除去水渠及人行道以外,有4m行间可以用。按80~10 0cm起垄,可以种4~5沟甘薯,随果树树冠发育逐年缩小甘薯用地。到了果树结果初期,为了便于管理果树,甘薯只种2~3 A reasonable allocation of land for potatoes According to the age of fruit trees and growth potential reasonable arrangements for the proportion of land for potatoes. To 5m × 3m specifications pear as an example: New Orchard 1 to 3 years between fruit trees to remove the canals and sidewalks, 4m lines can be used between. According to 80 ~ 10 0cm Ridge, you can plant 4 to 5 ditch sweet potato, with the development of fruit tree canopy shrinking year after year sweet potato land. To the early fruiting tree results, in order to facilitate the management of fruit trees, sweet potatoes only 2 ~ 3
