Prevention and Control measures for the phenomenon of Fruit Tree size

When it comes to the size of fruit trees, many fruit growers are not unfamiliar, and many orchards occur, especially in the peak fruit period. After the occurrence of large and small years, they blossom and bear fruit more in one year and less in one year, which brings huge economic losses to farmers. So how to prevent the year of fruit trees? Let's take a look.

1. Strengthen the management of orchards

The main reason for the size of fruit trees is that there is an imbalance between nutrient accumulation and consumption, so it is necessary to apply fertilizer scientifically to provide adequate ventilation for the growth and development of fruit trees, so as to balance their nutrient accumulation and consumption and reduce the information of the size of the year. Fertilization should pay attention to the application of base fertilizer and foliar spraying fertilizer in autumn, and organic fertilizer should be applied in one side of the plant before defoliation in autumn, so as to improve soil structure, increase permeability and promote plant to restore tree potential as soon as possible. When the root absorption of the plant can not meet the needs of growth, foliar fertilizer spraying can be taken to ensure the nutritional needs of the plant, which is generally in the flowering and fruiting stage, when the plant consumes more nutrients and the root system can not be fully satisfied.

2. Scientific pruning

It can improve pruning, coordinate the relationship between vegetative branches and fruiting branches, promote plant flower bud differentiation, improve fruit setting rate, and obviously increase branches and leaves for yield. However, during pruning, attention should be paid to the renewal of branches and the cultivation of branch groups, and the proportion of vegetative branches, fruiting branches and fruiting reserve branches should be arranged reasonably. The yield of some old fruit-bearing branches will decline all the time, so it can be shortened at this time, avoid nutrient consumption, and cultivate other new branches as fruit-bearing branches. this cycle can prevent and reduce the phenomenon of big and small years.

3. Fruit thinning and fruit protection

In production, in order to prevent and control the phenomenon of big and small years, the measures of thinning flowers and fruits in big years and protecting flowers and fruits in small years are often used. The time of flower thinning is generally in the early flowering stage, and the time of fruit thinning is generally one month after flowering. Fruit thinning early or too late will affect the measures of the plant. On the other hand, it is necessary to do everything possible to increase the nutrients in the plant, so as to ensure a large number of flower bud differentiation and pay attention to falling flowers and fruits in production.

4. Strengthen the protection of trees

It is necessary to observe the weather forecast in time, pay attention to the bad weather, such as frost, hail, and late spring cold, and take preventive measures in time; in winter, we should do a good job in comprehensively clearing the garden, burn or bury diseased branches, diseased fruits, diseased leaves, and ground weeds in time, reduce pathogens, and prepare for anti-freezing through spraying and whitening tree trunks, so as to make them safe to survive the winter. It is necessary to control diseases and insect pests through chemical spraying, root irrigation and other measures to reduce the incidence in the coming year.

The above is the introduction of prevention and control measures for the phenomenon of fruit trees. I hope I can't find you. If you want to know more about it, please follow us.
