Walnuts are a common nut that is loved for its high level of nutrition. To get more walnuts, many people choose to grow their own walnut trees. And to grow healthy, high-yielding walnut trees, seedling cultivation is key. The following will introduce to you how to cultivate walnut seedlings.
1. Choose the right seeds.
Selecting high-quality, adaptable walnut seeds is the first step in cultivating seedlings. It is recommended to choose full, pest-free seeds to ensure the quality and yield of seedlings.
2. Germination treatment.
In order to improve the germination rate of seeds, germination treatment is required. Soak the seeds in warm water and change the water daily until the seeds absorb water and swell. Then, the seeds are removed to dry and placed at a temperature of about 25 for germination. Once most of the seeds are white, the next step can be moved.
3. Prepare the soil.
The soil in which walnut seedlings are planted should be loose, fertile and well-drained. It is recommended to choose sandy soil rich in organic matter and add an appropriate amount of decomposed organic fertilizer to provide sufficient nutrients. The soil is ploughed, leveled and prepared for sowing.
Fourth, sowing. The germinated seeds are evenly sown in the soil, covered with a thin layer of soil, and gently compacted. Then, water and moisturize, and place in a warm, ventilated environment for maintenance. Generally speaking, the suitable sowing temperature is above 15 and the humidity is kept at about 70%.
5. Seedling management.
1.Watering and fertilizing: Keep the soil moist after sowing and water regularly. After the seedlings have grown 2-3 true leaves, the watering amount can be increased appropriately. At the same time, in order to promote the growth of seedlings, an appropriate amount of nitrogen fertilizer can be applied, but the principle of "small amount and many times" should be followed to avoid root burning.
2.Weeding and loosening soil: Remove weeds in time to avoid competing with seedlings for nutrients. At the same time, regular loosening of the soil helps to maintain the permeability of the soil and promote the growth of the root system.
3.Pest control: Regularly check the growth of seedlings, and take timely control measures when pests and diseases are found. Common walnut seedling diseases include root rot, leaf spot, etc., which can be controlled with corresponding fungicides.
4.Pruning and grooming: In order to develop a healthy, strong walnut tree, the seedlings need to be pruned and groomed properly. Prune weak branches and diseased branches in time to promote the growth of the main stem; At the same time, by adjusting the shape of the tree, the seedlings maintain a good form during the growth process.
5.Transplanting: When the seedlings grow to a certain size, they need to be transplanted. When transplanting, carefully dig up the seedlings to avoid damaging the root system. Choose a suitable location for transplanting, and pay attention to keeping the soil moist and shaded to improve the survival rate of transplanting.
With careful care in the above steps, I believe you will be able to cultivate healthy and strong walnut seedlings. Over time, these seedlings will thrive into tall walnut trees that produce delicious walnut fruits.
