Zhang Xicheng Liu Hui
The agrochemical market is confusion, fish eye passes as pearl, The weeding effect is irregular. This text conducts the research in view of the weeding effect in soybean production, trying to produce the best herbicide among 3 weed killers for the soybean production. In Liaoning Province Yingkou jail soybean experimental field, We atomizes the law with 3 weed killers including 28 % B experiment, 50 % B grass butters, 50 % grass to execute the medicine, after 40 days, investigate the category and stub number of the miscellaneous grass, fresh and heavy, compute stub to defend an effect with fresh and heavy defend an effect to study herbicide of in addition to grass result. The result express, 28 % B hang the milk 2 625 ml/hm2 of the stubs defend an effect to reach to 93.3 %, fresh and heavy defend an effect to reach to 96.1 %, 28 % B hang the milk 2 325 ml/hm2, 0.06 L/hm2 of the stubs defend the effect as 92.2 %, fresh and heavy defend the effect as 94.5 %, but 50 % grass s can the wet sex powder 1 125 ml/hm2 of fresh and heavy defend the effect as 94.9 %, slightly high hang the milk 2 175 ml/hm2 in 28 % B s 2, but the stub defend the effect as 90.7 %, the result is general is 50 % B grass butters 2 250 ml/hm2. 28 % B s hang the milk 2 325～2 625 ml/hm2 with 50 % grass scan the wet sex powder 1 125 kg/hm2, use once before the seedling and can immediately control after sow whole grow to expect miscellaneous grass bane.
