Although peach trees belong to self-pollination fruit trees, the pollen amount and pollination rate vary greatly among varieties. Some pollen cultivars have very few pollen percentages and even no pollen, which means that pollination trees must be prepared when the garden is established to arrange the flowering period. In the mature period, other fine peach varieties that are in line with their own varieties are planted nearby to increase the fruiting rate. The phenomenon that most of your flat peaches do not pollinate or fruit is probably due to neglect of this factor. It is advisable to replant other fine peach varieties with a 4:1 ratio between marginal open spaces in orchards or rows with large spacing. If you don't have free space to replant pollination trees, you can also implement the crown of the current peach tree. Change the head and change the species, that is, use other fine varieties with large amount of pollen to carry out high grafting, and the proportion of crown grafting may also be 4:1 (or more).
As for the cause of fruit cracking, it is mainly caused by improper management of water and fertilizer or pests and diseases. Peach trees should first perform scientific soil improvement and basic fertilizer application in the autumn and winter seasons. Generally combined with deep plowing, the open ditch with two feet deep and 1.5 feet wide can be used to fertilize and improve the soil, in order to accelerate the crown growth and lay the foundation for the flowering results. Second, to strengthen the irrigation and drainage work, the peach tree is the least resistant to drought, and it is not drought tolerant. Therefore, it is necessary to pay attention to drainage and flood prevention in the spring, and timely flood irrigation in the autumn to prevent falling fruit or fruit cracking. Finally, pests and diseases need to be controlled in time, except in management. To reduce human wounds as much as possible, but also to acupuncture to carry out chemical protection, seize the opportunity to prevent and cure.
