Generally, there are three key periods for watering high-quality thin-skinned walnuts: before freezing, before germination, and fruit expansion period. Watering before freezing is particularly important. One is that watering after fruit picking can effectively promote the decomposition of base fertilizer, increase the nutrient reserves of the tree body before overwintering, and improve the overwintering ability, which is conducive to budding and flowering in the following year. The second is to do it after the leaves are fallen to before the soil is frozen to prevent freezing and drought in early spring. The third is to reduce the base of the insect population. The key period of thin-skinned walnut fertilization is the application of base fertilizer after autumn. Generally, farmyard manure or decomposed organic fertilizers such as firewood and straw are the main ones. The ring or furrow fertilization method should be adopted. Topdressing before germination, apply 0.2-0.5 kg of urea, diammonium phosphate or special fertilizer for fruit trees to each young tree, and apply 0.5-1.5 kg per tree as a result, and it is advisable to adopt the method of cavitation fertilizer. Appropriate top dressing should also be used during fruit expansion. Disclaimer: Some articles on this website are transferred from the Internet.
