1981—1982年度我们在县原种场进行了小麦磷酸二氢钾浸种试验,供试小麦品种为郑选原种一代。10月27日播种。播前同0.25%磷酸二氢钾液浸种6小时,以清水浸种作对照。试验管理条件相同。小区面积2厘,三次重复,对比排列,条播。出苗后定点定株观察,成熟后取样考种。 磷酸二氢钾液浸种苗期早发,营养体生长发育快。与对照比较,始蘖期(11月5日)提前3天;年前(12月26日)单株分蘖多0.47个,每亩总苗数(63.24万)多6.04万,主茎叶
In 1981-1982, we conducted a wheat soaked potassium dihydrogen phosphate test in the original field in the county, the test wheat varieties Zheng generation of the original species. October 27 planting. Before sowing with 0.25% potassium dihydrogen phosphate soaking 6 hours, soaked in water as a control. Test management conditions are the same. Community area 2%, three times repeated, contrast arrangement, broadcast. Post-emergence of fixed-point observation after emergence, sampling samples after maturity. Potassium dihydrogen phosphate soaked early seedling stage, vegetative body growth and development fast. Compared with the control, the initial tillering stage (November 5) three days in advance; years ago (December 26) 0.47 more tillers per plant, the total number of seedlings per acre (632400) more than 60400, the main stems and leaves
