It can be used for seed dipping, seed mixing or root dipping, the specific dosage should be determined according to the fertility of the local soil and the reproductive period of the crop, in general, 0.01% brassinolide 2-3 ml per mu to 15-20 kg of water for seed mixing, seed dipping can be done 1 time before sowing or 1 time before the emergence of seedlings, and germination can be done 1 time in each of the 5-7 days after sowing, and it can also be used in the seedling stage of the crop.
It is not recommended to use brassinolide alone: the growth-promoting effect of brassinolide on crops is poor when used alone, and it is recommended to use it with nitrogen, phosphorus and potassium foliar fertilizers in order to get better growth effect.
In fruit trees, used to prevent disease brassinosteroid general concentration of 0.01% ~ 0.02%, if you want to increase production, can be used before flowering 0.01% brassinosteroid; in tomatoes, with 0.01% ~ 0.02% brassinosteroid can make tomatoes ripening 4 ~ 7 days earlier; in peanuts, with 0.01% ~ 0.15% brassinosteroid solution soaked seeds for 8 ~ 12 hours, can improve the seed germination rate of more than 40%; in the rice, with 0.01%~0.02% brassinol solution soaking seeds for 12 hours, can significantly improve the seed germination rate.
Seed treatment: can be dipped, mixed or dipped in the root, the specific dosage should be determined according to the fertility of the local soil and the reproductive period of the crop, in general, per mu with 0.01% brassinolide 2-3 ml to 15-20 kg of water for mixing the seeds, dipping the seeds can be before sowing or before the emergence of seedlings before the seeding of the dip 1, germination can be in the sowing of the seeds within 5-7 days of dipping the seeding of each 1, but also can be used in the seedling stage of the crop. It can also be used in the seedling stage of crops.
Increase yield and improve quality: brassinolide can improve crop resistance, such as resistance to dry and hot winds, resistance to low-temperature freezing, resistance to flooding, etc.; can promote photosynthesis, which is conducive to the absorption of more nutrients by the crop; can promote cell division, increase yield; can increase chlorophyll content, improve fruit quality.
