不同微生物肥和调节剂在大豆上的施用效果

Preliminary Report on Micro-fertilizer and Moderator Applied in Soybean

对 6种微生物肥和调节剂在大豆初花期叶面喷施的研究表明 ,肥力高等 6种微生物肥和调节剂都能促使大豆健壮生长 ,增加大豆的有效分枝、株粒数、百粒重 ,加快灌浆速度 ,提高光合速度 ,增加产量。其中以天然芸苔素和民裕有机活性液肥增产效果最好 ,增产 2 8.33 %和 2 1.42 % 。

The application of 6 micro-fertilizers and moderators at the stage of early bloom showed that all 6 micro-fertilizers and moderators can improve soybean growth, increase the number of branch and seed, and 100-seed weight, promote the rate of pod-filling and photorespiration and result in the yield increment. Among them, Nature-yuntaisu and Mingxu-bio-fertilizer get best effect and yield were significantly increased 28.33% and 21.42% respectively.
