近年来,随着农村生产技术水平的提高,植物生长调节剂的应用有了较快的发展,在提高作物产量和节约劳动力上的作用也越来越受到人们关注。但是,由于使用生长调节剂的技术性较强,其作用和效果受多种因素的影响,若使用不当不但不能增产反而造成减产。因此科学用药是确保药效的关键。使用时通常应注意以下问题: 一、熟悉各种植物生长调节剂的性能,选择作物适宜的药剂植物生长调节剂的种类多,性能各异。有对植物生长起促进作用的,也有起抑制作用的,许多种类还具双重效应(促进和抑制)。即使同一种生长调节剂,用在不同作物上效益也大不相同。如生长抑制剂B_9和矮壮素都能使植株矮化,
In recent years, with the improvement of the technical level of rural production, the application of plant growth regulator has developed rapidly, and the role of plant growth regulator in raising crop yield and saving labor has drawn more and more attention. However, due to the technicality of using growth regulators, their effects and effects are affected by many factors. If they are not properly used, they can not be increased but rather reduced in yield. Therefore, scientific medication is the key to ensure efficacy. The following questions should be paid attention to when using: 1. Familiar with the performance of various plant growth regulators and choose the suitable crops. There are many kinds of plant growth regulators and their performance are different. There is also a suppressive effect on plant growth, and many species have dual effects (promotion and suppression). Even if the same growth regulator, used in different crops have very different benefits. Such as growth inhibitors B_9 and CCC plants dwarf,
