Spring orchard management plays a crucial role in ensuring healthy fruit trees, particularly when it comes to fertilization and disease control. Based on years of experience, I would like to share some key recommendations for effective spring care:
Applying organic fertilizer and soil conditioners is essential. It's important to reduce the use of chemical compound fertilizers while ensuring that trace elements are adequately supplied. Recent field visits have shown that many fruit farmers are currently removing bark, and the problem of dead branches and trees is becoming more severe. This is largely due to soil degradation, which affects the root system’s environment. The more serious the soil damage, the more green moss appears under the tree canopy, the harder the ground becomes, and even common soil insects like cockroaches are almost gone. If the roots don’t have a healthy environment, they can’t absorb nutrients and water properly, leading to poor tree health, especially with issues like rot and rough skin disease.
In spring, it's also important to pay attention to the supplement of zinc, a critical trace element. Last winter was unusually cold, especially for orchards that didn’t receive autumn fertilization. Fruit trees were not well nourished, and as a result, many shoots and branches failed to leaf out properly, creating a "bald" appearance. After harvest, timely autumn fertilization is necessary to prepare the trees for the next growing season.
When choosing spring fertilizers, it's important to consider the nutritional needs during flowering. For orchards that were fertilized in autumn, high-nitrogen fertilizers such as Lion Horse 21-8-11 or Entek 26 and Entek 22-7-11 should be applied before flowering. Then, after flowering, high-nitrogen and high-potassium options like Zhongde 21-8-20 or 16-12-20 can be used, combined with additional nitrogen sources to support growth.
Pest and disease control in spring is a critical period. Taking preventive measures at this time can yield significant results. Combining bark scraping with applying a protective agent to wounds is an effective strategy. Once scale insects fall off and before flowering, timely chemical treatments should be carried out. The principle is to act steadily, accurately, and thoroughly. From my experience, this year’s pest and disease situation isn’t too severe, but farmers should still remain vigilant. Neglecting spring prevention can lead to unnecessary losses down the line.
Proper management in spring sets the foundation for a successful growing season. By focusing on soil health, nutrient balance, and early pest control, growers can ensure stronger, healthier trees and better yields.
