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％。
Through the 1978-1983 “784-1” spraying, soaking and seed dressing three kinds of application methods, after 113 test points nearly 2000 acres of field plot test, intermediate test and demonstration: First, “784-1” Soybean vegetative and reproductive growth have a promoting effect, can increase the leaf area and promote the accumulation of photosynthetic products, flower pods increased, increase the weight of 100, which constitutes a yield. Second, the spraying: mu with “784-1” active ingredient 21.42 grams watered 66.7 pounds Spray in the flowering soybean, 41 points, 1110.2 mu average yield of 8.28%. Third, soaking: “7B4-1” 200PPM dip bean seed 2 hours remove dry planting. 23 points 107.8 acres average yield 14.45%. Fourth, the seed dressing: the seeds can be attached to pure “784-1” 200PPM dose seed dressing. 41 points 603.5 acres an average increase of 12.24%.
