Detailed Explanation of Key Walnut Planting and Management Techniques
Choose a plot of sandy soil with sufficient fertility, and deep plow it while applying enough base fertilizer. Then select suitable walnut saplings and plant them in holes at a row-to-plant spacing of 4*5 m. Finally, cover with soil, water thoroughly to settle the roots, and spread a layer of rice straw on top. Once planting is successful, carry out basic management techniques such as watering and fertilizing, pruning and shaping, pest and disease control, and cold protection measures, and the trees will grow walnuts.
Walnut Tree Planting and Management Techniques:
1. Soil
For walnut trees to grow and develop well, suitable soil is essential. The fertility level of the soil directly affects the growth rate of the fruit trees and the fruiting rate. Carry out appropriate mid-tillage and hilling of the soil to increase the soil's water content, enhance the soil's permeability, improve the soil's fertility, promote the growth of walnut trees, and increase both yield and quality.
2. Pruning
Reasonable pruning is a key factor in making walnut trees high-yielding. If pruning is done after leaf fall or during the bud-break period, it is not conducive to wound healing and makes the tree highly prone to pests and diseases. Try to schedule pruning after harvest; pruning the tree at this time can effectively adjust the tree's structure. Although it will have a certain effect on nutrient accumulation, the problem is not serious.
3. Fertilizing
The growth of walnuts has a relatively large demand for nutrients. When carrying out mid-tillage and hilling of the soil, apply base fertilizer and mix and stir the base fertilizer thoroughly with the soil to enhance soil fertility. Later, apply additional fertilizer as appropriate according to the tree's growth conditions, weather changes, and the nutrient level in the soil. When fertilizing, do not pour the fertilizer directly into the pit; be sure to mix it evenly with the soil, or it may burn the tree roots.
4. Watering
Watering is essential. After planting, water once to settle the roots, and after each fertilizing and additional fertilizing, also replenish water to promote the roots' absorption of fertilizer nutrients. Walnut is a water-loving crop, so it is necessary to ensure the water needed during walnut growth. In continuous drought weather, replenish water in time to prevent walnuts from suffering water shortage, which would adversely affect growth and development.
5. Pests and Diseases
Walnut trees have strong disease resistance, and the pests and diseases that occur are fewer than in other crops, but sometimes pests and diseases are still caused by improper management. Failure to deal with pests and diseases in time can hinder growth and development or even cause death. Spray chemicals regularly for prevention, patrol the orchard, determine the disease according to its occurrence, and then treat it accordingly. After harvest, do a good job of disinfecting and cleaning the orchard.
6. Overwintering
Walnuts like moisture and tolerate waterlogging but are not cold-resistant, so after harvest it is also necessary to do a good job of overwintering work to prevent freeze damage. Before winter arrives, whitewash the lower part of the tree trunk to provide insulation. In snowy weather with heavy snow accumulation, promptly sweep away the snow around the tree. Cover with plastic film to increase the surface temperature and prevent freeze damage.
The above is an introduction to walnut planting and management techniques. I hope it is helpful to everyone.
