The method of thinning flowers and fruits of the latest plums
Plums have a large number of flowers and high fruit setting rate, but the nutrition of the tree is limited, a large number of flowers and fruits will consume a lot of nutrients, resulting in a large number of fruits, but less size and poor quality. Therefore, in order to obtain high-yield and high-quality fruit, it is necessary to thinning flowers and fruits in time. So how to do plum blossom and fruit thinning? Let's take a look.
1. The reason of flower and fruit thinning
In order to obtain high-yield and high-quality fruit, it is necessary to thinning flowers and fruits. Plum trees have a large number of flowers, 5-10 times the demand, and the excess flowers will consume a lot of nutrients, which is not conducive to the growth of fruits. The growth of fruit depends on leaves to supply nutrients, and the number of leaves is determined by the length of branches. After flowering for one month, the nutrient consumption of the tree is excessive, the growth of new shoots and shoots is blocked, the number of leaves and synthetic nutrients are reduced, which is not conducive to fruit growth, so timely thinning of some flowers and fruits and increasing the number of leaves can promote fruit growth and improve yield and quality.
2. Time of flower and fruit thinning
Generally speaking, flower thinning is carried out during flowering or flowering, and the time of fruit thinning is closely related to plum variety, tree age and climate. The varieties with high fruit setting rate should be sparse early, on the contrary, the fruit setting rate should be low and late; according to the tree age, the number of adult fruit should be precocious, while young trees or newly fruited plants should be late sparse. Under normal circumstances, fruit thinning is generally carried out 15-20 days after flower fade, when the fruit also grows to the size of bean grains, and fruit thinning is in place at one time. Attention should also be paid to some situations when thinning flowers and fruits. It is not suitable for varieties that are vulnerable to freezing injury, varieties with less pollen and plants growing in adverse environment, but their fruit thinning is generally carried out during the second physiological fruit drop. At this time, there are also some differences in fruit growth, leaving strong fruit and thinning weak fruit.
3. The method of thinning flowers and fruits.
Thinning flowers should remove late flowering, deformed flowers, morning smallpox and flowers without branches and leaves, and leave flowers in the upper and middle parts of branches and leaves, generally thinning 1/3 of the flowers. On the other hand, the fruit thinning should remove the double fruit, small fruit, abnormal fruit and overgrown fruit, and take the fruit according to the branches, generally leaving more fruit in the upper part and less fruit in the lower part, so as to control the fruit growth and make it reach a balance. For the plants with strong tree potential, it is appropriate to leave more fruit, while the tree is weaker and less fruit.
The above is the introduction of plum blossom and fruit thinning methods, hope to help you, want to know more related knowledge, please pay attention to us.
