一、培育壮苗壮苗移栽发根快,发根多,换苗快,生长健壮,抗寒力强,春发好。宝鸡县桃园大队用壮苗移栽的亩产270斤;弱苗移栽的230斤;选剩小苗移栽的仅160斤,越冬死苗率达18%。武功县东魏店生产队用壮苗移栽的亩产280斤,比弱苗移栽的增产30%。壮苗标准:苗龄40—45天,绿叶6—8片,苗高7—8寸,叶色绿,叶柄短粗,侧根发达,无高脚,无病虫。培育壮苗措施:1.选地与作畦:育苗可利用早玉米地或场地,需具备灌水条件。早玉米地要求土地
First, nurturing strong seedling seedlings transplanted hair root fast, more hair roots, seedling fast, robust growth, strong cold, spring hair good. Baoji County Taoyuan brigade with strong seedling transplanting 270 kg per mu; weak seedlings transplanted 230 pounds; the remaining transplanted seedlings only 160 pounds, overwintering dead seedlings rate of 18%. East Wei shop Wugong County production team with seedlings transplanted 280 kg per mu, transplanting than the weak seedlings 30% increase. Strong seedling standard: seedling age 40-45 days, green leaves 6-8, 7-8 inches tall seedling, green leaves, petiole stubby, lateral roots developed, no tall feet, no pests.
