据“气候障碍的化学疗法”理论 ,利用维生素类物质为主体复配研制的“维他灵”2号。在玉米上的应用试验结果表明 :“维他灵”2号的最佳喷施时期为大喇叭口后期。最佳使用量为 375ml/hm2 。对玉米植株性状具有明显的调控作用 ,株高矮化 2 9.2cm、穗位高降低 10 .9cm、茎基粗直径增加 0 .2 9cm、气生根增多 2 6 .3条。同时具有显著的增产作用 ,增产 2 2 .4 2 %。增产表现在增加穗粒数和千粒重
According to the theory of “climatic disorder chemotherapy”, the vitamin “Vitalin” No. 2 is developed by using vitamin substances as the main compound. The application of corn on the test results show that: “Vitalin” 2 the best spraying period for the late bell stage. The best use of 375ml / hm2. The plant traits of corn had a significant regulatory effect. The plant height was dwarfed by 2 9.2 cm, the ear height was decreased by 10.9 cm, the stem diameter was increased by 0.29 cm, and the number of aerial roots was increased by 26.3. At the same time, it has a significant increase in yield and an increase of 22.42%. Yield performance increased grains per spike and 1000-grain weight
