地膜育苗能提高苗木的产量和质量,经济效益明显,是加速培育优质苗木的好办法。 1982年5月10日用地膜覆盖育苗1.2亩,其中新疆杨贴接扦插1亩,I—214杨0.2亩。1983年春地膜育苗6亩,其中新疆杨“一条鞭”扦插育苗1.5亩,新疆杨贴接扦插1.8亩,I—214杨1.2亩,45~#杨1.2亩,其他柳树品种0.3亩。 一、作法 1、整地、作床、铺膜、扦插 作床前进行深翻整地,拣净草根、石块。每亩施基肥7000斤,饼肥200斤、碳铵 Plastic film seedling nursery stock can improve the yield and quality, economic benefits are obvious, is to accelerate the cultivation of good seedlings a good way. On May 10, 1982, 1.2 mu mu of seedlings were covered with plastic mulch, among which 1 mu was affixed by cuttings of Xinjiang Poplar and 0.2 mu was I-214 Yang. In the spring of 1983, 6 mu mu of plastic seedlings were planted. Among them, 1.5 mu of cuttage seedlings of Xinjiang “one whip” was poplar, and 1.8 mu of I-214 Yang, 1.2 mu of I-214 Yang, 1.2 mu of 45 # poplar and 0.3 mu of other willow varieties were affixed to Xinjiang Poplar. First, the practice 1, site preparation, as a bed, film, cuttings for bed deep before turning, pick net grass roots, stones. 7000 kg per acre base fertilizer, 200 kg cake fat, ammonium bicarbonate
