补充资料:沟播种谷法(furrow-sowing of millet)
沟播种谷法(furrow-sowing of millet) 将谷种播在预先开好的浅沟内的种植方法,又名壅谷或壕谷,由古代 “圳田”演变而来。是一种防倒抗旱的栽培技术。中国华北、西北土层深厚、肥力高、有灌溉条件的地区可采用。在干旱、半干旱地区也常作为一种有效的抗旱保苗方法。技术要点是 “种植抗病品种,开沟播种,集中施肥,宽幅密植,分期平沟,培土成垄”。使粟“种在沟里,长在垄上”。播种前种子先用盐水选种,清水漂洗晾干,药剂处理种子。开沟播种,集中施肥。土地整平后先开沟,沟距40cm,沟深15cm。集中施肥于沟内,粪土混合均匀后,整平沟底。每公顷播量7.5kg,播后覆土3-4cm,镇压1-5次。大面积种植沟播谷,可用悬挂式沟谷播种机。以12马力小型拖拉机牵引,一次播种两沟,沟距可以调整。开沟、施肥、播种、覆土、镇压一次完成。每小时可播种0.3ha.。 宽幅密植,在保苗的基础上,宽幅留苗,加大密度。幼苗出土后,第一真叶展开时,镇压一次;2-3叶后,喷施乐果防虫;3-4叶定苗,宽幅调角间苗,每公顷留基本苗90-120万株,使粟苗生长在沟内。 分期平沟,培土成垄。苗高16-17cm时,沟施有机肥,分两次用垄上的土把沟填平。苗高50-65cm时,追施氮素化肥,并分两次往根际培土成垄,使植株生长在垄上。 沟播谷增产的科学道理,一是壮根防倒。二是放宽行距,宽幅密植。在集中施肥,增施肥料的基础上,由于播幅较宽,虽然加大了群体,但植株分布均匀,加上手间苗和清垄等措施,个体与群体的发育比较协调,植株生长整齐一致,株高、穗长、茎粗的变异系数分别比平播谷相对减少。因而,群体的光能利用率较高。 |
