Abstract
The invention relates to a water-soluble calcium-magnesium fertilizer and a preparation method thereof. The water-soluble calcium-magnesium fertilizer is prepared from the components of a compound amino acid solution, magnesium nitrate, quicklime and ammonia water, wherein the compound amino acid solution is prepared by treating hairs by virtue of concentrated sulfuric acid, and the magnesium nitrate, the quicklime and the ammonia water are all sold commodities. The preparation method comprises the steps of adding the magnesium nitrate and the quicklime in the prepared compound amino acid solution to carry out reaction, regulating a pH value of the liquid by virtue of the ammonia water to be 7, filtering, drying and packaging to prepare the water-soluble calcium-magnesium fertilizer.
Description
Technical field
The present invention relates to a kind of water-soluble calcium magnesium fertilizer and preparation method thereof, this fertilizer can provide calcium magnesium nutrition for crop, the physiological disturbance that prevention and treatment crop cause because of calcium deficiency, magnesium.
Background technology
Calcium constituent is that crop normal growth is grown indispensable nutritive element, rationally use calcareous fertilisers, especially happiness calcium crop as: the crops such as apple, tomato, Chinese cabbage need the calcium critical period to use can effectively prevent and treat the physiological disturbance that crop causes because of calcium deficiency, for high yield and high quality lays the first stone.
Calcium can be used as the bridge contacting between the phosphate radical of phosphatide and the carboxyl of protein in microbial film, thereby can maintain the stability of membrane structure.Calcium is a kind of element that forms cell walls, and the middle lamella of cell walls is made up of calcium pectinate.When calcium deficiency, cell walls forms and is obstructed, and affects cell fission, or can not form new cell walls, occurs syncyte.Therefore grow when calcium deficiency suppressed, children's tender organ (tip of a root, stem end) necrosis of festering when serious.Calcium has certain effect to plant disease-resistant.It is reported, the physiological disease that has 40 various fruits and vegetables at least causes because of calcium deficiency, and during as Chinese cabbage calcium deficiency, lobus cardiacus is brown.Apple can cause acne pinta and cracked fruit in young fruit period calcium deficiency.Calcium is also the activator of some enzymes, as all needed the participation of calcium ion by enzymatic reactions such as ATP lytic enzyme, phosphatide lytic enzymes.Calcium is ionic condition and exists in plant materials, is mainly present in leaf or old Organ and tissue, and it is the element of a very difficult movement.Therefore, traditional calcium fertilizer product absorptive character are poor, cannot meet the needs of supplementing calcium element completely.
Magnesium is the moiety of plant chlorophyll, and it is metallic element unique in chlorophyll molecule; Magnesium is the activator of plurality of enzymes; Magnesium is the neccessary composition of polysome, can also promote to do the formation of vitamin A, C in object.Therefore, use fertiliser containing magnesium and can promote the photosynthesis of farm crop, promote the synthetic of protein, improve the output of farm crop and improve the quality of agricultural-food.According to another report, magnesium can also promote the absorption of plant to silicon, is conducive to prevent germ intrusion; Can also reduce the absorption of plant to manganese, alleviate the disease effect of manganese when too much; In the time executing the magnesium of lower concentration, can also promote the absorption of calcium.Distribution at crop magnesium is generally the highest with seed content, and cauline leaf takes second place, and root is minimum.In general, leguminous crop is higher containing magnesium than gramineous crop, normally 2 times of cereal crop of the absorbed dose of root crop magnesium.Potato, tomato in citrus, banana, spinach sieve, tobacco and the vegetables of the paddy rice of field crop, peanut, sesame, cash crop class are all the crops that needs magnesium more.
In recent years, China has occurred causing the phenomenon of the underproduction because magnesium deficiency causes the yellow leaf of paddy rice.Along with the development of husbandry, the increase year after year of Fertilization Level and high-concentration fertilizer, becomes clear day by day to the requirement of magnesium, especially in the many acid sandy soil areas of quantity of precipitation.
