The latest course of High-yield cultivation techniques of Hawthorn

Hawthorn is a kind of fruit that everyone is very familiar with, which has the function of appetizing and promoting digestion. Hawthorn planting is also very common in China. When planting Hawthorn, the yield must be of great concern to everyone. So how can we cultivate Hawthorn to produce high yield? Today, the editor has brought you the cultivation techniques for high yield of Hawthorn. Let's take a look at it.

1. Applying basic fertilizer and ring cutting in autumn

When planting Hawthorn, the fruit is usually picked in late autumn. After fruit picking, we should apply an appropriate amount of base fertilizer, which can improve the nutrient accumulation in Hawthorn tree, which is also very beneficial to the flower bud differentiation of Hawthorn tree in the second year. The base fertilizer is mainly organic fertilizer, combined with appropriate amount of chemical fertilizer. When applying base fertilizer, we should pay attention to mixing it fully and then applying it into the soil to prevent excessive heat from burning roots. Then for some exuberant young trees to be properly ring-cut, can intercept the leaf production of organic matter, can be concentrated supply to flowers and fruits, promote the formation of flower buds, to achieve the purpose of controlling shoots and promoting flowers.

2. Topdressing at flowering and fruiting stage

Before Hawthorn blossoms, the fertilizer of topdressing is generally nitrogen and phosphorus fertilizer, and its dosage should be kept at about 35% of the whole year. In the young fruit stage, the purpose of topdressing is to provide nutrition for the early stage of flower bud differentiation. Then potassium fertilizer is the main topdressing in fruit expansion stage, which promotes the growth of fruit and increases the content of carbohydrate in fruit. Topdressing in the flowering and fruiting stage is very important, because Hawthorn has a great demand for nutrition when it blossoms and bears fruit. Adequate fertilizer is the key to improve fruit setting rate and fruit quality, so we must pay more attention to it.

3. Careful pruning

The pruning of Hawthorn trees should generally be carried out in winter. The work of transforming and rejuvenating trees. Remove the whorled backbone branches and some overdense and large branches on the tree. Especially all kinds of competitive branches, only growing branches and disease and insect branches. When pruning, the buds left in the appropriate parts should be properly selected for small renewal to cultivate a robust branch group. If the branch is weak, it should be re-cut and rejuvenated and scratched to increase the branch. After pruning, the wound should be covered with anticorrosive film to prevent dry cracking and being harmed by diseases and insect pests.

4. Pre-harvest watering and pest control

Watering Hawthorn properly or applying appropriate amount of water-soluble fertilizer before harvest can increase the yield by about 40%. And the more dry it is, the better it will be to increase production. If proper amount of water fertilizer is applied to Hawthorn, it can also increase the rate of flower bud differentiation and reduce the annual fruit and fruit drop. Finally, in the dormant period of Hawthorn tree and before sprouting in spring, we should pay attention to the prevention and control of diseases and insect pests. Protect the flower buds of Hawthorn tree, carry out disinfection and sterilization, heat preservation and anti-freezing to ensure the normal growth of Hawthorn tree.

The above is a brief introduction of high-yield cultivation techniques of Hawthorn. That's all for today's introduction. This article is for reference only. I hope it can help you all.
