Problems solved by technology

[0003] After ordinary fertilizers are applied to cultivated land, part of them will be transpired, dissipated or lost with water, part of them will be used by soil and soil microorganisms, and only a small part of the rest will be absorbed and used by crops. Sweet potatoes are high-yielding crops that require a relatively large amount of fertilizer. During the growth cycle, a large amount of nutrients need to be absorbed. If the fertilizer is insufficient, it will cause the adverse consequences of weak plants, small number of tubers, and low yield. It is difficult to provide enough nutrients for ordinary fertilizers.
[0004] The fertilizers currently on the market for the application of sweet potatoes are generally aimed at supplementing certain elements or using ordinary chemical fertilizers. In fact, the effective absorption of fertilizers during the planting of sweet potatoes is less than 50%, and the nutritional value of many fertilizers is low. Being wasted, that is to say, the utilization rate of commonly used fertilizers is very low, so research on the ability to release fertilizers many times to supply the nutrients needed for sweet potato growth is also very necessary and needs to be resolved urgently

Abstract

The invention discloses a special compound fertilizer for promoting potassium absorption of sweet potatoes and a preparation method thereof. The special compound fertilizer is characterized by being prepared from the following raw materials by mass: 60-80 parts of a silicate bacterial fertilizer, 200-300 parts of urea, 80-120 parts of ammonium phosphate, 80-120 parts of ammonium hydrogen carbonate, 150-200 parts of straw, 40-60 parts of potassium chloride, 40-60 parts of zinc sulfate, 80-100 parts of chestnut shell, and 50-100 parts of a soil conditioner. The special compound fertilizer provided by the invention has rich nutrients and balanced ratio, contains organic fertilizer in the formula, increases the organic matter content of soil, improves soil, and significantly enhances the yieldand quality of sweet potato fruits, and also can dissolve out insoluble potassium from potassium-containing minerals in soil for sweet potato utilization through the silicate bacterial fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special compound fertilizer for promoting potassium absorption of sweet potatoes and a preparation method thereof. Background technique [0002] Sweet potato, also known as sweet potato and sweet potato, is the root of an annual plant in the family Convolvulaceae. Its skin is whitish or red, and its flesh is mostly yellowish white or purple. In addition to being edible, it can also be used to make sugar, wine, and alcohol. The calorie content of sweet potatoes is very low, which is much lower than that of ordinary rice, so you don't have to worry about getting fat when eating sweet potatoes. On the contrary, eating sweet potatoes can play a role in losing weight. Sweet potatoes also contain a substance similar to estrogen, which has a certain effect on protecting human skin and delaying aging. In some developing countries, sweet potatoes are used as the staple ...
