How to thinning flowers and fruits of the latest pear trees
Pear trees have a large amount of flowering, and if there are too many fruits, the tree will be overloaded, which will affect the fruit quality, make the fruit small, and cause the phenomenon of big and small years because of the massive consumption of nutrients, and sometimes there will be the phenomenon of turning green and flowering. So in the production of pear trees in flower thinning and fruit thinning necessary measures, so how to carry out? Come and have a look with the editor.
1. Flower thinning method
Pear tree flower thinning can save tree nutrients more than fruit thinning. If the excess flowers are removed as soon as possible, it can concentrate on tree nutrition supply and flower and fruit growth and tree development. In the case of more flowers and less natural disasters, flower thinning is more beneficial to pear varieties with high fruit setting rate than fruit thinning. Pear tree flower thinning can be seen in winter and pruned before blooming in spring, but the main time of flower thinning is before flowers bloom, the first two can only save nutrients, if sprouting is tantamount to thinning branches. It can not change the branch-fruit ratio, while flower thinning can retain the auxiliary shoot of fruit platform, increase the branch-fruit ratio and leaf-fruit ratio, and play a good role in improving fruit quality and customer service year. The time of flower thinning is generally from April to May, and it can be carried out from inflorescence separation to full flowering, and the earlier the better. Generally, the center of thinning is left on both sides, and the top of the tree is kept in the middle.
2. Fruit thinning time
The fruit thinning time of pear trees is related to its varieties. Generally, sand pears begin one week after flowering, and fruit thinning is completed within half a month, while green pear varieties must be bagged 10 days after flowering, so fruit thinning should not be too late. The fruit thinning of general pear trees ends at the latest 26 days after flowering, and the fruit cell division period is within one month after flowering. Fruit thinning as soon as possible can promote the increase of seedling cell number and volume, but has little effect on fruit cell division if fruit thinning is too late. This not only affects yield and quality, but also wastes nutrients and inhibits flower bud differentiation.
3. Fruit thinning method
For pear fruit thinning, we should first remove the fruits with diseases and insect pests, poor fertilization, improper shape, persistent calyx and short vertical diameter. The shape and growth potential of fruit is directly related to the sequence of inflorescence. The vertical diameter of the fruit in the low order position is shorter, the stalk is also thick and short, the fruit in the young fruit stage is obviously larger, but the later growth potential is small, while the fruit in the high order position is longer, the young fruit is small and the stalk is slender, and the growth potential is smaller; only the fruit in the middle order position has a longer vertical diameter, the young fruit is larger but the stalk is thick and long, and the growth potential is the greatest. In general, it is thought that the first and second order fruits should be removed, because their vertical diameter is short, the fruit is small, and the yield and quality are not high after maturity.
The above is the pear tree how to thinning flowers and fruit introduction, hope to help you, want to know more related knowledge, please follow us.
