In agriculture, we often use pesticides. The main role of pesticides is to kill pests and prevent them from causing harm. Dwarf hormone is a plant growth regulator, but it is also widely used in agriculture.
One, the seeds "eat hot" injury relief
Rice: When the seed temperature exceeds 40℃ for more than 12 h, the seed is first washed with clean water, and then soaked with 250mg/L drug solution for 48 h. The drug solution is to inundate the seeds. After cleaning the liquid, sprout again below 30℃ to partially relieve the harm of "eating heat".
Second, cultivate strong seedlings
Wheat: Use O. 3% ~ 0. 5% infusion for 6 h, solution: seed -1: O. 8. Dry and sow seeds, spray seeds with 2% ~ 3% liquid, and sow seeds for 12 hours after sowing, which can make the seedlings strong, the root system developed, the tillers increased by 12% or so.
Maize: immerse the seed for 6h with dilution of 80 ~ 100 times with 50% water l]. The liquid should be used to flood the seed. After sowing in the shade, the plant can be made strong, with well-developed root system, low rod position, no baldness, large ear and full grain, and the yield can be increased significantly.
Third, restrain the growth of stem and leaf, resist lodging and increase yield
Wheat; At the beginning of jointing at the end of tillering, spraying dwarf element can effectively restrain the elongation between 1 and 3 at the lower part of stalk, which is beneficial to prevent wheat lodging and improve the heading rate. In the use of dwarf element we also want to grasp the amount, to avoid excessive amount of crop damage, the correct use can bring help, so we must first understand the product information before using.
