In October, the autumn of fruit trees will gradually stop growing and maturing. In order for fruit trees to bear more fruits, it is necessary to understand the laws of flower bud differentiation and take corresponding technical measures to promote good flower bud differentiation. If the quality of flower buds is good, the fruit setting rate will be high, and the result will be naturally Trust Mart. So how can fruit trees promote flower bud differentiation in October?
On the one hand, it is important to avoid excessive fertilization in autumn, especially to strictly control the amount of nitrogen fertilizer used, otherwise it will cause the problem of excessive growth and delayed lignification and ripening in autumn. On the other hand, 0.3% potassium dihydrogen phosphate can be sprayed 1-2 times continuously from the beginning of autumn to the end of the long term, every 7-10 days. By supplementing phosphorus and potassium, it can promote the cessation of autumn ripening as soon as possible. For fruit trees that have excessive growth in autumn, You can spray paclobutrazol+potassium dihydrogen phosphate 1-2 times in autumn when it is slightly ripe to 80-90%, every 10-15 days, or apply high phosphorus and potassium water-soluble fertilizer before and after mid October for flushing, which can effectively promote the rapid cessation of aging in prosperous autumn.
At the same time, autumn is also a critical period for fruit tree flower bud differentiation. We can use potassium dihydrogen phosphate, Xirui medium and trace element fertilizer, and paclobutrazol for foliar spraying, combined with management methods such as autumn branch pulling, to promote higher quality differentiation of fruit tree flower buds.
