Problems solved by technology
[0003] In the vigorous development of the walnut industry, many problems have also been exposed. There is a widespread "reinvention and light management". Among them, fertilization management has become one of the key links that restrict production and improve efficiency. Influenced by management habits, scattered and free-range cultivation, most walnut trees have not paid enough attention to fertilization and neglected fertilization management, resulting in poor growth and low yield; on the other hand, there is a lack of materials to supply suitable walnut special fertilizers Basic and mature fertilization technology guidance, fertilization has a lot of blindness, and there are common problems such as single fertilization or general compound fertilizers that are not well targeted, resulting in poor fertilizer efficiency, poor economic benefits, and difficulty in achieving expected results

Abstract
The invention particularly relates to a special compound fertilizer for walnuts, and the fertilizer is prepared from the following components in parts by weight: 30-36 parts of organic fertilizer, 46-62 parts of macroelement fertilizer, 0.4-2 parts of microelement fertilizer and 5-10 parts of clay. Nutrient elements required for fruiting of walnut trees are added, formulas under various soil character conditions of the walnut suitable ecological environment are fully considered, lime is added during afforestation and soil preparation of acid soil, and soil acidity can be relieved and neutralized; diammonium phosphate is added into the alkaline soil, so that the alkalinity of the soil can be relieved and neutralized; for neutral soil, it is suggested that an alkaline soil formula is emphatically applied, formula nutrients are comprehensive, organic matter is used for improving soil, the compound fertilizer is high in specificity and integrates organic matter and inorganic matter, and the blank of the compound fertilizer special for walnuts in Qinba Mountain areas can be filled up.
Description
technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for walnuts. Background technique [0002] Walnut is one of the ancient dry fruit tree species widely distributed and rich in resources in the world. Among the many economic tree species, walnut is famous for its wide range of uses and nutritious kernels. Walnut kernels are beneficial to intelligence and brain, walnut oil is beautiful and prolongs life. Walnut wood is noble and elegant, and walnut flowers are natural mountain treasures. They are all treasures. [0003] In the vigorous development of the walnut industry, many problems have also been exposed. There is a widespread "reinvention and light management". Among them, fertilization management has become one of the key links that restrict production and improve efficiency. Influenced by management habits, scattered and free-range cultivation, most walnut trees have not paid e...
