Karst shrub revetment vegetation selenium-enriched trace fertilizer and preparation method thereof

Abstract

The invention discloses a preparation method for a karst shrub revetment vegetation selenium-enriched trace fertilizer. The karst shrub revetment vegetation selenium-enriched trace fertilizer consists of major elements and rare elements which are required by plants and the fertilizer is prepared by the following raw materials by weight of: 36 to 38 of nitrogen, 12 to 14 of phosphorus, 1.3 to 1.5 of sulfur, 11 to 13 of potassium, 2 to 2.4 of calcium, 0.8 to 0.9 of magnesium, 1 of selenium fertilizer, 2 of zinc, 1.4 to 1.5 of boron, 1.2 to 1.3 of manganese, 1.1 to 1.2 of copper, 2.1 to 2.4 of ferrum, 0.06 to 0.07 of molybdenum and 6.2 to 8 of sodium. Compared with the conventional common fertilizer, the karst shrub revetment vegetation selenium-enriched trace fertilizer comprises various major elements and trace elements, particularly mineral substance elements, such as selenium, silicon and ferrum, so that the fertilizer is used conveniently and efficiently and can promote the growth and the development of plants; the resistance of the plants is improved effectively; and the whole effect is good.

Description

technical field [0001] The invention relates to a selenium-enriched micro-fertilizer for karst shrub slope protection vegetation and a preparation method thereof, belonging to the field of fertilizer and its preparation. Background technique [0002] The concentration of trace elements in plants is relatively low, generally lower than 1.0ppm, but they play an indispensable role in the life activities of plants. It is a component of enzymes or coenzymes in plants, has strong specificity, and is indispensable and irreplaceable in the process of crop growth and development. Therefore, when plants lack any kind of trace elements, their growth and development will be inhibited, resulting in reduced yield and quality. When plants have sufficient trace elements, their physiological functions will be very strong, which is conducive to the absorption and utilization of "macroelements" of crops, and can also improve the colloidal chemical properties of cell protoplasm, thereby increa...

AI Technical Summary

Problems solved by technology

The application of compound fertilizers with incomplete nutrient elements will not only fail to adjust the pH value of the soil, but also disturb the nutrient composition of vegetation. Nutrients cannot be effectively absorbed and utilized by plants, resulting in waste, and chemical substances such as nitrogen, phosphorus, and potassium are easily consolidated by the soil to form various chemical salts, which causes the soil nutrient structure to be out of balance and the physical properties to deteriorate. Harmful metals and harmful bacteria exceed the standard, leading to deterioration of soil properties

The imbalance of soil nutrients will also lead to nutritional imbalance of plants, and the conversion and synthesis of some substances in the body will be hindered, resulting in stunted growth.
