我所从1976—1978年,连续三年进行玉米就地加代试验,经过几年工作,已选出几个较有希望的玉米自交系和杂交组合。我们进行就地加代的方法是:头茬玉米青苗移栽采用阳畦育苗移栽法,先作成长10米,宽1米的畦,畦面低于地平面2—3寸,撒施捣碎的优质圈肥及少量种肥硫酸铵,用铣翻下整平,如墒情不好可适量喷水,然后划成1寸方格按株系播种。于3月8日点播,覆土3厘米,畦上扎弓形架,盖上塑料薄膜。3月20日出全苗。3—4叶时中午将塑料薄膜打开晒苗,移栽前要整日晒苗2—3天。4月14日幼苗长到5—
From 1976 to 1978, I conducted on-site maize in-generation tests for three consecutive years. After several years of work, I have selected several promising maize inbred lines and hybrid combinations. We carry out on behalf of the generation of the method is: the first crop of young corn transplanting Yang Yang nursery transplanting method, first for the growth of 10 meters, 1 meter wide and 畦 畦 surface less than 2-3 inches above ground level, spreading mashed High quality circle fertilizer and a small amount of fertilizer ammonium sulfate, with the milling turn leveling, such as water quality is not good, proper water spray, and then into a 1-inch grid sown by strains. On March 8, on-demand, soil cover 3 cm, tie the bow on the frame, covered with plastic film. March 20 out of seedlings. 3-4 leaf noon plastic film to open the sun seedlings, seedlings before transplanting to the whole day 2-3 days. April 14 seedlings grow to 5-
