为比较氨水冬施和春施的经济效益,杨一四队和史壕十队科学实验小组分别作了对比试验。杨一四队试验情况:75年冬施氨水100亩,每亩150斤。挨着冬施氨水档子,每亩春施氨水150斤作对照。两条地都是三年老旱田,地力相似,76年亩春施土粪67小车、羊粪大粪混合粪250斤,碳铵150斤,钙镁磷肥100斤作基肥,头水时追尿素25斤,品种斗地1号。测产结果,冬施株高120厘米(春施101厘米),穗粒数26粒(比春施多2粒),千粒重均为42克,亩产907斤,比春施的增产60斤。史壕十队试验情况:亩基施土粪65小车、羊粪200斤、普钙80斤,品种斗地1号,3月
In order to compare the economic benefits of ammonia application and spring application, Yang Yishan and Shi Hao ten scientific experimental groups made comparative experiments respectively. Yang a team of four test conditions: 75 years of winter ammonia water 100 acres, 150 pounds per mu. Next to the ammonia fertilizer application in winter, 150 mu of acre spring acacia as a control. Both are three-year-old dry field, similar to the land, 76 years of spring Shi Tu manure 67 vehicles, sheep manure mixed manure 250 pounds, ammonium bicarbonate 150 pounds, 100 pounds of calcium magnesium phosphate fertilizer for basal, headwater, urea recovery 25 Kg, variety of land on the 1st. Measured results, the winter plant height of 120 cm (spring facilities 101 cm), 26 grains per spike (more than spring Shi 2 more), a grain weight of 42 grams, 907 kg per mu, yield 60 kg more than spring. History of trench ten teams test conditions: mu base Shi soil manure 65 carcasses, 200 pounds of sheep manure, calcium 80 pounds, varieties of land on the 1st, March
