Flower and Fruit Thinning Technique of Loquat

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

1, thinning flowers

In winter, there is no freezing injury area, generally in the flower ear pumping out but not flowering, that is, 11-12 months, thinning flowers according to tree vigor, variety only. First of all, the number of flower ears depends on the tree potential. Generally speaking, each ear of large fruit type is calculated by 0.2 kg, and each ear of medium fruit type is calculated by 0.15 kg. 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 ears, so that the fruit maturity of the whole plant can be suppressed. In areas prone to freezing injury and sunburn, more flower spikes in the crown should be left when thinning flowers, and flower thinning should be combined with fruit thinning after freezing injury.

2. Bud thinning

An important measure of loquat bud thinning is to save nutrients and concentrate nutrients to cultivate large fruits. There are two main links: one is to remove the top of the flower spike and become the tail of the spike; the other is to remove the basal branch of the flower spike. In addition, it is necessary to keep the branch axis with the flower ear upturned upward, and keep the branch axis hanging down in the middle. The specific branch axis is determined by the variety. Generally, 3-4 branch axes are reserved for large-fruit varieties, while 4-5 branch axes are reserved for medium and small varieties. After such thinning, not only the loquat fruit size is large, the maturity period is also relatively consistent, but also convenient bagging, the fruit is not easy to be burned. In the area without freezing injury, if the bud thinning is selected as early as possible, the fruit setting rate can be obviously improved; while in the area with freezing injury, if it is suitable for selecting late opening, the flower quantity may be left one more seat, the flowering period of fertilization is postponed, and the freezing injury period is avoided.

3. Fruit thinning

Fruit thinning is generally carried out after the young fruit is stable, that is, about 1 month after fruit setting, when the fruit has not yet entered the rapid expansion period, fruit thinning can make the fruit evenly distributed, the number is moderate, and the average fruit weight is about 50-60 grams. First of all, we should thin out abnormal fruits, diseased fruits, injured fruits and frozen fruits, and then thin out some fruits with less growth in batches. When thinning fruit, try to select some young fruits with similar size, color, position and orientation, which can save harvesting time. The number of fruits per panicle should be determined according to the variety and tree vigor. Generally, 2-4 grains per panicle for large fruits and 3-5 grains for medium fruits.
