1、对李子栽培分析探讨;随着特别经济林的发展,农民致富奔小康已在农村这块天地不断有了新的变化,李子树在吕梁山区是一个很特殊的核果类树种,喜光也稍耐荫,抗寒,适应性强,以温暖湿润的气候环境和排水良好的沙质壤土最为有利,怕盐碱和涝洼。浅根性,萌蘖性强,对有害气体有一定的抗性。李树栽植最好选择土质肥沃、疏松的土壤建园。选择土壤性质较差的岗、坡地建园的,建园前后要加强对土壤改良,提高肥水管理水平。;1栽培技术;1)选苗。选择品种纯正、根系完整、健壮、芽质饱满、无检疫对象和无病虫害的李子苗。2)定植。一般株行距为2.5m×
2、4.0m,芽未萌发前(最好在4月20日前)栽植。李子有自花不孕现象,因而,栽培品种不宜单一,应隔一定距离栽植花期一致的不同品种做授粉树,比例为4∶1或8∶1。;2肥水管理;2.1科学施肥organizationsystemandworkingmode,theselectionofanumberofmunicipalstrengtheninggrouptobuildinnovationandstrengthentheorganizationofthebasiclevelorganizationsadvanced
