What are the key points of orchard management in early spring? How to prevent diseases and insect pests?

With the rise of the temperature in spring, fruit trees begin a new annual growth period, which is what we call early spring. The management of fruit trees in this period is very critical, which will affect the yield and quality of subsequent fruits. What are the key points for the management of the orchard in early spring? How to prevent diseases and insect pests?

What are the key points for the management of orchards in early spring?

1. Spray the potion at the right time

Generally speaking, during the overwintering period, when diseases and insect pests are more active, it is very important to spray fruit tree remover at this time, which can effectively reduce the phenomenon of unearthed pests and damage to fruit seedlings in spring. The commonly used agents are phoxim, methyl thiophanate, cypermethrin, mancozeb and so on.

2. Fertilize the fruit trees before sprouting.

If we want fruit trees to grow neatly and steadily when they sprout, we should apply a certain amount of budding fertilizer when the roots are already active in early spring. If it has been given sufficient fertilizer, it can reduce the amount of application, or do not apply it directly, because it has met the growth needs of fruit trees.

3. Turn over the soil

Why turn over the soil and just open the surface of the soil? Because this can destroy the storage areas of diseases and insect pests (the temperature is relatively low in winter, a large number of underground pests such as tigers and beetles will hide in the soil) can also improve the moisturizing effect of the soil. So we turn the soil and loosen the soil in time in early spring, which can effectively reduce the occurrence of diseases and insect pests. At the same time, when turning the soil, the fallen leaves and weeds of fruit trees can also be buried in the soil.

Second, how to prevent diseases and insect pests in early spring in orchards?

1. Agricultural Prevention and Control Law

This method is a method to reduce or control the occurrence of diseases and insect pests through some ways in nature, such as reasonable arrangement of planting density of fruit trees, change of soil environment, selection of varieties with strong disease resistance or rotation and intercropping. According to traditional methods, we can create a production environment that diseases and insect pests do not like, such as destroying the living space of diseases and insect pests, hidden places, so that we can directly control the occurrence of insect pests or directly eliminate insect pests.

2. Physical and mechanical prevention and control methods

The common ways of physical and mechanical prevention and control are equipment hunting, bagging isolation, trapping and killing, the application of radioactive energy, mainly the use of more advanced tools, machinery and equipment to achieve the purpose of pest control.

3. Biological control

Biological control is mainly through the protection of natural enemies of fruit tree diseases and insect pests or through artificial means to release natural enemies, this way is more used in the prevention of diseases and insect pests, because the effect is more obvious.

To sum up, the management of orchards in early spring is very important, and it is also a key factor in the high yield of fruit trees. During this period, we should also do a good job in the prevention and control of diseases and pests.
