Which fertilizer is best for fruit trees in winter?

When fertilizing fruit trees in winter, choosing appropriate fertilizers is very important for promoting the growth of fruit trees, enhancing their resistance to disease and drought, and increasing the fruit setting rate. Let’s learn together which type of fertilizer is best for applying to fruit trees in winter?

1. Organic fertilizer

Including mature compost, manure, manure, green manure, crop straw, human feces, urine, chicken manure, etc. These fertilizers not only provide nutrition for fruit trees, but also increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of the soil.

2. Inorganic fertilizer

Including nitrogen, phosphorus and potassium compound fertilizers , which can provide more balanced and comprehensive nutritional supplements, achieve the effect of promoting root growth and quickly regulating the natural health of fruit trees. Generally, 30-50 kg of urea, 100-200 kg of superphosphate, and 50-100 kg of potassium sulfate are used per mu, and trace elements are supplemented as needed.

3. Biological fertilizer

It contains a large number of beneficial microorganisms, which can improve the soil environment and enhance the disease resistance of fruit trees. The scientific use of bacterial fertilizer has the benefits of improving soil fertility, growing strong trees and producing high-quality fruits, and extending the economic life of trees.

4. Trace element fertilizer

Although fruit trees do not require much trace elements, a lack of them can lead to problems such as poor growth and reduced yields. In winter, appropriate amounts of trace element fertilizers such as iron, zinc, boron, etc. can be applied.

To sum up, it is recommended to use a combination of biological fertilizer, organic fertilizer and inorganic fertilizer for winter fertilization, which will have the best effect. Organic fertilizers can provide long-lasting nutrients, inorganic fertilizers can quickly replenish nutrients, and biological fertilizers and trace element fertilizers can help improve the soil environment and enhance the disease resistance of fruit trees. Such a combination can provide comprehensive nutrition for fruit trees, help them survive the winter safely, and lay a good foundation for their growth next year.
