The latest course of loquat flower thinning and fruit thinning techniques

Loquat is very easy to form flowers and ears, in order to adjust the proportion of leaves and fruits, save nutrients, ensure that the fruit has sufficient nutrient growth, and achieve high yield every year, so it is necessary to carry out flower and fruit thinning measures in production. So how to thinning flowers and fruits in loquat? Let's take a look at the detailed introduction.

1. Flower thinning

First, in areas where there is no frost injury in winter, it is generally carried out when the ears of flowers are drawn out but not in bloom, that is, from November to December, and the flowers should be thinned according to the tree situation and variety. First of all, it depends on the tree potential to determine the number of flower spikes. generally speaking, the large fruit is calculated as 0.2 kg per panicle, and the medium fruit type is calculated as 0.15 kg per panicle. When thinning flowers, the upper part of the crown should be more sparse, and the lower part should be less sparse. At the same time, attention should be paid to the early and late flowering spikes, so as to inhibit the fruit ripening period of the whole plant. In the areas prone to frost injury and sunburn, more flowers should be left in the crown when thinning flowers, and fruit thinning should be combined with fruit thinning after freezing injury occurs.

2. Shu Lei

One of the important measures of loquat bud thinning is to save nutrients and concentrate nutrients to cultivate large fruit, which mainly has two links: one is to remove the top of the flower ear to become the tail of the flower ear, and the other is to remove the base supporting axis of the flower ear. In addition, it is also necessary to keep the upwarped branch axis of the mustard flower ear, and retain the drooping branch axis in the middle, which depends on the breed. Generally, the large fruit type varieties have 3-4 branches, while the small and medium-sized varieties have 4-5 branches. After such thinning, not only the fruit size of loquat is large, the ripening period is also consistent, but also convenient for bagging, the fruit is not easy to burn. In the areas where there is no frost injury, if the buds open early as far as possible, the fruit setting rate can be significantly increased; while in the areas with frost injury, if it is suitable to choose to open late, the amount of flowers may be left one more, the flower and fruit period of fertilization will be postponed, and the period of freezing injury can be avoided.

3. Fruit thinning

Fruit thinning is generally carried out after the young fruit is stable, that is, about 1 month, when the fruit has not yet entered the period of rapid expansion, fruit thinning can make the fruit uniform distribution, moderate quantity, can ensure that the average weight of a single fruit is about 50-60 grams. First of all, it is necessary to remove the deformed fruit, disease and insect fruit, injured fruit, freeze-damaged fruit, and then sparse some less growing fruits in batches. When thinning fruit, we should try to keep some young fruits with similar size, color, position and orientation, so as to save harvest time. The number of fruits per panicle should be determined according to the variety and tree potential, generally leaving 2-4 grains per panicle for large fruit and 3-5 grains for medium fruit type.
