Fruit tree spraying time

1. Before flowering

Before the fruit trees bloom, they need to be sprayed with fruit-preserving drugs. This can increase the chance of fruit setting, increase the yield of fruit trees, and reduce the chance of fruit drop. The types of agents that can be used are growth regulators, which can regulate the growth of fruits. The main ones are gibberellins, naphthylacetic acid, etc., and the concentration does not need to be too high. In addition to using growth regulators, trace elements should also be supplemented, the most important of which is boron, which can effectively promote the germination of pollen, help complete fertilization, and can also be mixed with sugar.

2. After the flowers fall

Within 7-10 days after the flowers wither, it is necessary to apply a pesticide to prevent diseases and pests to reduce the possibility of diseases and pests and eliminate hidden dangers. The specific type of medicine used depends on the type of fruit tree. There are many options, such as lime sulfur, which is more effective and the cost is not high.

3. Fruit expansion period

During the fruit expansion period, you can spray the fruit stem with a strong agent to make the fruit stem thicker and increase the amount of nutrient transport. In the later stage, it can prevent the fruit from falling or causing deformed fruits.
