在干旱半干旱地区果园为节水保水,我们在衡水市邓庄乡试行果园覆草。开始时参照外地经验:覆盖厚度15—20厘米,每亩用桔秆3000公斤,以后每年加盖800公斤。冬季保持覆盖层,以保护覆盖层下发达的表层根,避免表层根受损后削弱树势。结果表明覆盖有显著的保水作用。特别是桃树,根系浅,5—6月干旱少雨,又值果实膨大期,水份短缺影响果实生长。覆草果园土壤含水量
In the arid and semi-arid areas of orchards for water and water conservation, we Hengshui Township, Hengshui City pilot orchard grass. Reference to foreign experience at the beginning: cover the thickness of 15-20 cm, 3000 kg per mu with orange stalk, after the annual capping 800 kg. Keep the cover in winter to protect the developed surface under the cover roots, to avoid damage to the surface roots and weaken the tree potential. The results show that the cover has significant water retention. In particular, peach trees, shallow roots, 5-6 months of drought, but also the value of fruit expansion, water shortage affect the fruit growth. Grass orchard soil moisture content
