一、树盘覆草、覆秸秆等,以保持土壤水分 在沙土地,树盘不加覆盖,地温可超过40～50℃,在此温度下根系常会枯死。 二、增施有机肥,提高土壤持水力。 三、把果树接于抗旱性强的砧木上 此法虽不是应急措施,但必须注意要使根深扎土中,以吸收稳定而多量的水分。特别易旱的地方可预先选耐旱的砧木嫁接,也可在果树生长中途用根接法来补救。
First, the tree covered grass, straw, etc., in order to maintain soil moisture in the sand, tree without cover, the ground temperature can exceed 40 ~ 50 ℃, at this temperature often dead roots. Second, increase organic fertilizer, improve soil water holding capacity. Third, the fruit trees pick drought resistant rootstock Although this method is not an emergency measure, but must pay attention to make the root deep soil, in order to absorb a stable and large amount of water. Particularly drought-prone areas can be pre-selected drought-resistant rootstock grafting, but also in the middle of the fruit tree growth method used to remedy.
