近年来我省连续引进一批二棱大麦品种,在各地试种收到较好的效果。为了解这些品种与播种期的相互关系,以便合理利用,全省组织了这次品种播种期试验。试验于1983—84年度在湖南农学院实验农场进行。 一、试验材料和方法 试验选用二棱大麦品种矮早三、76—25,早熟三号为供试材料。第一期11月12日播种,以后每7天播种一期,共播四期。田间用随机区组设计,重复三次。小区面积2厘。试验地前作凉薯,肥力中等。播种前在播种沟内亩施稀猪粪水50担,钙镁磷肥50斤。播幅4寸,幅距4寸,按每亩基本苗15万折算播种量。12月24日第一、二播期亩施尿素10斤,3月6日第三、
In recent years, a batch of two-rowed barley varieties have been introduced continuously in our province, and good results have been received through trial planting in various places. In order to understand the relationship between these varieties and sowing date, in order to make rational use, the province organized the sowing date experiment. The experiment was conducted in 1983-84 at Hunan Agricultural College Experimental Farm. First, the test materials and methods Two-rowed barley varieties with short early morning three, 76-25, precocious three for the test material. The first phase of November 12 planting, sowing every 7 days after a total of four broadcast. Field randomized block design, repeated three times. Residential area 2%. Before the trial for the potato, moderate fertility. Before sowing in the sow ditch Mushi pig dung 50 Tam, calcium magnesium phosphate 50 pounds. Sowing 4-inch, 4-inch amplitude, according to the basic seedlings per acre 150,000 converted sowing. December 24 first, second sowing urea 10 kg acre, March 6 third,
