为提高新建苹果树的成活率,在1987和1988年连续两年在城关镇西关和南关两村,于5月下旬至6月上旬,对定植当年而迟迟不发芽和濒临枯死的苗木,进行了“堆土埋干”试验,取得了很好的效果。两年总埋270株,成活244株,平均成活率达90.3%,而对照68株,只成活10株,平均成活率14.7%。这种堆土埋干法对在水源缺乏的旱山地果园更为适用。堆土埋干的具体作法是:将迟迟不发芽
In order to improve the survival rate of new apple tree, in 1987 and 1988 for two consecutive years in Chengguan Town, Xiguan and South Gate two villages, from late May to early June, the year of planting and the delay in the budding and dying seedlings, Conducted a “pile of soil Buried” test, and achieved good results. 270 plants were buried in two years and 244 survived, with an average survival rate of 90.3%. In comparison, 68 were survived and 10 survived, with an average survival rate of 14.7%. This pile of buried soil dry law in the water shortage of dry mountain orchard is more applicable. Buried soil embankment specific practice is: will not delay germination
