云大—120(芸苔素内酯)是国际上最新型的高效植物生长调节剂.为探索在新疆干旱荒漠生态条件下,对棉花、玉米的影响,安排进行应用试验,示范结果:有增强抗逆性(连续高35.7—41.5℃达25—35天);能提高叶绿素含量和光合作用;能促进花粉受精,提高座果率和结实率.其考种表明,单株增铃0.4—0.6个,单铃重提高0.5—0.6克,不孕籽降低1.5—1.6粒;改善作物品质,绒长增长1.8—1.9mm,衣分比对照提高3.1—3.3%.生物活性极高,每亩次有效用量仅0.25—2.5毫克,就可增产6.95—7.03%,亩获经济效益72—73.5元.投入产出比为1:14.4—14.7,是科技兴国,发展高科技农业,有推广前景的新科技.
Yun-Da-120 (Brassinolide) is the latest efficient plant growth regulator in the world.In order to explore the impact of arid and desert ecological conditions on cotton and corn in Xinjiang, the application test was carried out. The results show that there is enhancement Resistance (continuous high 35.7-41.5 ℃ for 25-35 days); can improve the chlorophyll content and photosynthesis; can promote pollen fertilization and improve the rate of fruit set and seed setting rate of their test showed that the single bolus 0.4-0.6 A single boll weight increased 0.5-0.6 grams, 1.5-1.6 pieces of infertile seeds to reduce; improve crop quality, cashmere growth of 1.8-1.9mm, 3.1-3.3% higher than the control points. High biological activity, acre The effective amount of only 0.25-2.5 mg, 6.95-7.03% yield increase, economic benefits of 72-73.5 yuan per mu. Input-output ratio of 1: 14.4-14.7, is the science and technology to rejuvenate the country, the development of high-tech agriculture, the promotion of the new prospects Technology.
