果树栽培学家确认,果树在深秋或初冬栽植最好。此时的气温与土温比较一致,土壤蒸发量也小,但土温仍然较高。果树栽上之后,当年即发新根。苹果根系生长在土温7℃。桑树在土温5～6℃也能发根。翌年春,气温回升后,新根系即可吸收水、肥,供应树
Fruit growers confirm that fruit trees are best planted in late autumn or early winter. At this time the temperature and soil temperature more consistent soil evaporation is also small, but the soil temperature is still high. After the fruit trees planted, the year that is, a new root. Apple roots grow in soil temperature 7 ℃. Mulberry in the soil temperature 5 ~ 6 ℃ hair roots. The following spring, the temperature rises, the new roots can absorb water, fertilizer, supply tree
