Brassinolide was first discovered by an American agricultural scientist in 1970 in rape pollen as a new compound, so it is also called brassinolide. Because it is found in plants and produced by the plant itself, it is placed alongside the five major hormones of auxin, gibberellin, cytokinin, abscisic acid and ethylene, and is called the sixth major category of plant hormones. At that time, it was discovered that this new compound not only has the physiological functions of auxin and cytokinin, but also has the functions of improving photosynthesis and regulating nutrient distribution. It can also promote the transport of carbohydrates from the stems and leaves of crops to fruits and grains, and improve crop resistance. The ability to resist adverse external factors and the ability to promote the growth of weaker parts of plants. Brassinolide is the same as the potassium dihydrogen phosphate that we have shared before. It can also be applied to any crop at any period. Different periods of use also have different effects. Simply put, it can be summarized as the following 6 points: 1. Promote seed germination and root growth. In addition to foliar spraying, brassinolide can also be used as a seed treatment to break seed dormancy and promote seed germination; spraying in the seedling stage of crops can promote the growth of seedling roots. 2. Promote cell division and vegetative growth. When the crop enters the growth period, spraying brassinolide can regulate the vegetative growth of the crop, promote the thick stem and the formation of plant chlorophyll, improve photosynthesis, make the leaves thick and green, and delay leaf senescence. 3. Promote the differentiation of flower buds and increase the rate of fruit setting. Brassinolide can promote the formation of side branches and side buds of crops, promote the differentiation of flower buds, increase the pollination rate after the crops bloom, and promote the formation of crop fruits or grains. 4. Promote fruit expansion and increase crop yield and quality. Brassinolide can promote cell division, thereby swelling the fruit; promote protein synthesis and dry matter accumulation, increase sugar content, and improve fruit quality; at the same time, it can also make the fruit grow evenly, with beautiful color, and improve The commercial nature of crops. 5. Improve crop resistance. Brassinolide not only promotes the growth of crops, but also enhances the ability of crops to resist natural disasters such as high temperature, low temperature, freezing damage, salinity, and drought, and can play a role in enhancing the ability of crops to resist disease attack. 6. Alleviate phytotoxicity. When crops are harmed by improper use of herbicides and insecticides, spraying brassinolide and foliar fertilizer in time can alleviate the harm. The 0.01% brassinolide preparations currently on the market are relatively common. Taking 0.01% content as an example, the dilution factor is generally about 2500 times, which is equivalent to using about 6ml brassinolide for 15 kg of water in a pot of water. For specific use, it can be combined with specific crops and the different growth periods of the crops to make appropriate up and down fluctuations. Use period: seedling stage, before flowering and after fruit setting, fruit swelling stage or filling stage. Brassinolide itself does not provide nutrients for crops, so it is best to mix it with foliar fertilizer for better effect.
