Last Updated: 2024/11/22, The basis of apple flowering and fruiting during flower bud differentiation, apple yield and quality need high-quality flower buds as a guarantee, but in the production of many fruit trees, there is little flowering, or even no flowering and the phenomenon of big and small years is serious. Therefore, reasonable flower promotion techniques should be adopted to create flower buds.

The basis of apple flowering and fruiting during flower bud differentiation, apple yield and quality need high-quality flower buds as a guarantee, but in the production of many fruit trees, there is little flowering, or even no flowering and the phenomenon of big and small years is serious. Therefore, the use of reasonable flower promotion technology to create the best conditions for flower bud differentiation and ensure the quality of flower bud differentiation has an obvious effect on improving yield and quality.

1. Attach importance to fertilizer and water management

In the early stage, it is necessary to promote the growth of branches and leaves of fruit trees, which is conducive to the synthesis and accumulation of photosynthates, especially for big year trees with more fruit, timely fertilization during the critical period of flower bud differentiation in June, with emphasis on phosphorus and potassium fertilizer, less nitrogen fertilizer and moderate water control. However, due to excessive drought and loss of water in leaves at noon, proper irrigation is needed, which is conducive to flower bud differentiation.

2. Choose a place to build a garden

It is appropriate to choose high altitude, leeward and sunny place to build a garden, and at the same time, reasonable and close planting, generally planting 22-33 trees per mu, 1-7 years as the trunk, 8-111 as the trunk, and 12-15 years to complete the happy type. While the semi-dwarf and spur type trees are 44-55 per mu, the tree type should be improved to spindle shape, and the dwarf trees should be planted with 66-83 pigs per mu, and the tree type should keep slender spindle shape. After pruning the standard tree type, the suitable ventilation and light transmission conditions were created for flower bud differentiation.

3. Strengthen pruning in the growing season

Fruit tree growing season pruning is mainly aimed at young and prosperous trees, which should be pruned more and less, pruning lightly, balancing the tree potential, pulling branches, shrinking weak trees, thinning branches and leaves too dense, and intercepting branches and leaves for older trees. In summer, coring, ring peeling, branch pulling and thinning can be used to minimize the thinning of fruit trees, change waste branches into branch groups, change long branches into medium and short branches, and change leaf buds into flower buds.

4. Thinning flowers and fruits

Big year trees should be thinning flowers and fruits early, and the yield per mu should be controlled at about 3000 kg, which can not only prevent excessive nutrition consumption, but also improve fruit quality. Moreover, it overcomes the main contradiction among fruit, seed and flower bud, which is beneficial to the formation of flower bud and prevents the occurrence of big and small year phenomenon.

The above is the introduction of Apple flower promotion management technology. I hope it can help you. If you want to know more about it, please follow us.
