Asked the netizen of Jiangsu Province, "Xue Jiahua line": Can geranium can use paclobutrazol? how to use?

Answer: guaiazole can be used for paclobutrazol, the use of paclobutrazol can reduce the height of the plant, increase the diameter of the crown, early flowering, prolong the role of flowering period, but will reduce the number of buds to some extent.
Use at the seedling stage (reference concentration is 0.1-0.3mg/l), foliar spray, continuous use 3 times, interval 10 days, mixed with 0.1% potassium dihydrogen phosphate, 0.05% boron is better. The mixed solution of the three components has the effect of increasing the weight of seeds by one thousand grains and can treat the retained plants.
The use of paclobutrazol is not only a science but also an art. The same concentration will have different effects in different varieties, regions, and seasons. In order to accurately grasp the timing and concentration of the spray, it is necessary to record in detail the environmental conditions of each spray, the humidity of the substrate used, the temperature after use, and the light conditions.
Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
