近几年来,红花草子在不少地方出现滑坡,据笔者调查首要原因就是缺苗严重,越冬基本苗不足。过去,每亩常有30～40万基本苗越冬,翌年约产鲜草2000～3000公斤,可养田2～3亩。而眼前有些绿肥田越冬苗不到10万,有的甚至成了“真板田假绿肥”。一、基本苗不足的主要原因 (一)种子发芽率低,播量不足。千家万户种绿肥,自己留种的不多,多靠买种商品种,泥砂多,陈子多,贮藏方法不良。播种前如不精
In recent years, Safflower appears landslide in many places, according to the main reason I survey is lack of seedlings, lack of winter seedlings. In the past, 30-40,000 mu of basic seedling per acre were overwintered, with about 2000-3000 kilograms of fresh grass in the following year and 2 to 3 mu of paddy fields. In front of some green manure overwintering seedlings less than 100,000, and some even became a “true green paddy field fertilizer.” First, the main reason for lack of basic seed (A) the seed germination rate is low, sowing less. Thousands of households planted green manure, not much to keep their own species, mostly by buying species, silt and more, more than Chen, poor storage methods. If not slender before sowing
