提高砂石山坡地春栽果树成活率的技术鲁南地区常年２—４月的降水量约３０ｍｍ；当年开发的砂石山坡地土壤含水量极少，常导致春栽果树成活率很低。我们于１９９４年４月中下旬在店子镇春栽长把红樱桃、红富士苹果、长木大枣共３３ｈｍ２（公顷），当年栽植成活率分别达８... The technology to improve the survival rate of spring planting fruit trees on gravelly hillsides is about 30mm in the Lunar New Year. The soil moisture content of gravelly hillsides developed very little in that year often leads to low survival rate of spring planting fruit trees. We in mid and late April 1994 in Dianzi Zhenchun planted long red cherry, red Fuji apple, long wood jujube total 33hm2 (hectare), when the planting survival rates were up to 8 ...
