The latest prevention and control measures for the annual phenomenon of fruit trees

Many fruit farmers are familiar with the size of fruit trees, and many orchards will occur, especially in the peak fruit period. After the size of fruit trees, there will be more fruits and fewer fruits in one year, which will bring huge economic losses to farmers. So how do you prevent fruit tree size? Let's take a look.

1. Strengthen orchard management

The main reason for fruit tree size is that the nutrient accumulation and consumption are unbalanced, so scientific fertilization is needed to provide sufficient ventilation for fruit tree growth and development, so that the nutrient accumulation and consumption are balanced, and the information of size year is reduced. Fertilization should pay attention to autumn application of base fertilizer and foliar fertilizer, in autumn before defoliation, in the plant side open ditch application of organic fertilizer, improve soil structure, increase permeability, promote plants to restore tree vigor as soon as possible. When the root system absorption of the plant cannot meet the growth needs, foliar fertilizer can be sprayed to ensure the nutrient requirements of the plant. In this case, the plant generally consumes a large amount of nutrients during the flowering and fruiting period, and the root system cannot fully meet the requirements.

2. Scientific pruning

It can improve pruning, coordinate the relationship between vegetative branches and fruiting branches, promote flower bud differentiation, improve fruit setting rate, and obviously increase branches and leaves for yield. However, attention should be paid to the regeneration of branches and the cultivation of branch groups when pruning, and the proportion of vegetative branches, fruiting branches and fruiting preparatory branches should be arranged reasonably. Some old fruiting branches yield will always decline, so at this time you can cut them short to avoid nutrient consumption, cultivate other new branches as fruiting branches, this cycle can prevent and reduce the phenomenon of big and small years.

3. Fruit thinning and fruit preservation

In order to prevent and control the phenomenon of big and small years in production, the measures of thinning flowers and fruits in big years and protecting flowers and fruits in small years are often used. The thinning time is generally in the early flowering stage, and the thinning flowers are generally after one month after the flowers fade. The thinning time should be grasped well. The early or late thinning of fruits will affect the measures of plants. And young flower protection fruit should do everything possible to increase the nutrients in the plant, so as to ensure that its flower bud differentiation quantity is numerous, in production should pay attention to flower drop fruit.

4. Strengthen tree protection

To timely observe the weather forecast, pay attention to frost, hail, late spring cold and other bad weather, timely preventive measures; in winter to do a good job of comprehensive garden cleaning work, sick branches, sick fruits, sick leaves and ground weeds timely burned or buried, reduce pathogenic bacteria, through spraying, trunk painting white and other measures, do a good job of frost resistance preparation, so that it can safely winter. For diseases and insect pests, measures such as pesticide spraying and root irrigation should be adopted to reduce the incidence of diseases in the coming year.

The above is an introduction to the prevention and control measures of fruit tree size phenomenon. I hope I can't find you. If you want to know more about it, please pay attention to us.
