种植绿有有如下几种方式:
  (1)
单作
绿肥
。即在同一
耕地
上仅种植一种
绿肥作物
,而不同时种植其他
作物
。如在开荒地上先种一季或一年绿肥作物,以便增加
肥料
增加
土壤有机质
,以利于后作。
  (2)间种绿肥。在同一块地上,同一
季节
内将绿肥作物与其他作物相间种植。如在
玉米
行间
种竹豆、黄豆,
甘蔗
行间种
绿豆

豇豆

小麦
行间种
紫云英
等。间种绿肥可以充分利用
地力
,做到用地
养地
,如果是间种
豆科绿肥
,可以增加主作物的氮素营养,减少
杂草

病害

  (3)套种绿肥。在主作物播种前或在收获前在其行间播种绿肥。如在
晚稻
乳熟期播种紫云英或
苕子

麦田
套种
草木樨
等。套种除有间种的作用外,不觉有使绿肥充分利用生长季节,延长生长时间,提高绿肥
产量

  (4)混种绿肥。在同一块
地里
,同时混合播种两种以上的绿肥作物,例如紫云英与
肥田萝卜
混播
,紫外线云英或苕子与
油菜
混播等。群众说:“种子掺一掺,产量翻一番。”豆科绿肥与非豆科绿肥,蔓生与直立绿肥混种,使互相间能调节
养分
,蔓生茎可攀缘直立绿肥,使
田间
通风透光。所以混种产量较高,改良
土壤
效果较好。
  (5)插种或
复种
绿肥。在
作物收获
后,利用短暂的空余生长季节种植一次短期绿肥作物,以供下季作物作
基肥
。一般是选用生长期短、生长迅速的绿肥
品种
,如绿豆、
乌豇豆

柽麻
、绿萍等。这方式的好处在于能充分利用
土地
及生长季节,方便管理,多收一委绿肥,解决下季作物的肥料来源。
