Effects of Brassinolide on Wheat
Dressing before planting. Brassinolide seed dressing wheat can significantly improve the germination rate and promote rooting, and it has been widely practiced in recent years. The specific amount is 0.01% of brassinolide per 30 catties of seeds, 10 to 15 ml mixed with (can be carried out according to the actual situation of each place).
It is used at the early flowering stage of wheat. The use of brassinolide at the early flowering stage of wheat helps to improve the pollination and fertilization rate of pollen, thereby increasing the number of effective panicles and grains per panicle. The effective panicles and average number of grains per panicle in all drug treatments are more than those in the clear water control. , the number of effective ears increased by more than 2% compared with the control.
Use in the greening period of wheat. During this period, the wheat in the early spring entered a period of vigorous growth. At this time, the temperature was abnormal. The main effect of spraying brassinolide on the wheat was to prevent freezing.
Use before the low temperature in winter. The main effect of spraying brassinolide on wheat is to prevent freezing before the low temperature comes. Prevent the cold in spring and promote the turning green of tillers! It is recommended to use 0.01% brassinolide 15ml per acre!
Used at the booting stage of wheat. Using it before wheat blooming promotes cell division on the one hand, making the quality of booting higher, and also plays a role in growth regulation, laying a good foundation for wheat blooming, thereby improving the pollination rate in the later period.
It is used during the grain filling period of wheat. This period is probably when the last medicine of wheat is used. The use of brassinolide this time is mainly to promote grain filling, which greatly improves the filling rate and the grain of wheat is full. It is recommended to use 0.01% brassinolide 10ml per mu of land. . It is best to use with some potassium dihydrogen phosphate.
Use at heading stage of wheat. Spraying brassinolide in the early flowering stage of wheat can help to promote pollination, improve fertilization rate, increase the number of effective panicles, and increase wheat yield. Spraying brassinolide at the early stage of wheat grain filling increased the wheat ear length and the thousand-grain quality.
To sum up, it can be seen that spraying brassinolide in different growth periods of wheat has different yield-increasing factors, and has different benefits on the growth of wheat. Growers can choose to use Brassinol for wheat seed dressing and pre-winter spraying according to the drug level. However, after the year, it is recommended that farmers use it 2-3 times. Its yield increase effect is very obvious. If it is used well, it is possible to increase the yield of one or two hundred catties per mu of land!
