【摘要】 通过1978—1983年用”784—1”喷施、浸种和拌种三种施药方式,经113个试验点次近2000亩的田间小区试验,中间试验和示范:一、“784—1”对大豆的营养生长和生殖生长均有促进作用,可增大叶面积,促进光合产物的积累,花荚增多,提高百粒重,因而构成增产。二、喷施:亩用“784—1”有效成分21.42克兑水66.7斤于大豆盛花期喷雾,41点次,1110.2亩平均增产8.28％。三、浸种:“7B4—1”200PPM药液浸豆种2小时捞出晾干播种。23点次107.8亩平均增产14.45％。四、拌种:使种子能附着纯“784—1”200PPM的药量拌种。41点次603.5亩平均增产12.24％。更多还原

【Abstract】 Field trials and demonstration of "784-1" -CH2CH2CH2OHincluding 113 tests were performed in spraying, seed soaking and seed dressing on an area of 2,000 mu during 1978-1983. The results are as follow.1. Spraying-yield increased by 8.66% in case of spraying "784-1" on soybean plant completely during full bloom, area of field plots for all 41 sites-1110.2 mu, the dosage is 21.42 g per mu.2. Seed soaking-yield increased by 14.45%, area of field plots for 23 sites-107.8 mu, using 200 ppm "784 1" soaking for two hours before sowing.3. Seed dressing-yield increased by 12.24%, area of field plots for 41 sites-603.5 mu, using 200 ppm "784-1" dressing.更多还原
