在我省南通,扬州的高沙土地区,土地瘠薄,缺水少肥。经试种了两旱一水三熟制后,夏绿肥套种面积逐年增加,取得了土地越种越肥,产量越种越高的良好效果。两旱一水耕作制(下面简称两旱一水)又称旱、旱、水或软三熟。种植的主要方式是:冬绿肥间作三麦(蚕豆)→玉米套种夏绿肥→后季稻。即冬季进行麦肥间作,春季压青绿肥作玉米基肥,成为麦与玉米共生,麦子收后灭茬套种夏绿肥,又成为玉米与夏绿肥共生,7月下旬收玉米,掩青夏绿肥作基肥,栽后季稻。这样,实行冬春粮肥间作,夏季粮肥套种,一年两肥三粮,当年水旱轮作。在泰县、如皋县一带,结合饲料生
In our province Nantong, Yangzhou high sand soil area, barren land, water less fat. After the trial of two dry and one dry three-year system, the summer green manure area increased year by year, and achieved more land more fertilizer, the higher the yield the better results. Two dry and one hydroponic farming (hereinafter referred to as two dry and one water), also known as drought, drought, water or soft three cooked. The main methods of planting are: winter green manure intercropping three wheat (broad bean) → corn intercropping summer green manure → after-season rice. That winter intercropping wheat, spring pressure green manure as corn-based fertilizer, wheat and corn symbiosis, wheat stubble after interception summer green manure, corn and summer green fertilizer has become symbiotic, maize in late July, cover green summer green manure, Season after planting rice. In this way, the implementation of intercropping winter and spring grain and fertilizer, intercropping summer fertilizer, a year two fat three grains, then drought and drought rotation. In Tai County, Rugao area, with feed raw
