Multifunctional hyper-concentrated liquid organic inorganic fertilizer for vegetables and preparation method thereof

Abstract

The invention relates to multifunctional hyper-concentrated liquid organic inorganic fertilizer for vegetables and a preparation method thereof. The multifunctional hyper-concentrated liquid organic inorganic fertilizer comprises 8-18 parts of urea, 8-12 parts of monoammonium phosphate, 15-22 parts of ammonium sulfate and 58-59 parts of amino acid organic nutrient solution, wherein the proportion of effective components N to P2O5 to K2O is 8-12:4-6:9-11. The multifunctional hyper-concentrated liquid organic inorganic fertilizer has the advantages that the fertilizer can increase vegetable yield and quality and increase fertilizer utilization rate and is low in cost and efficient; the fertilizer contains multiple kinds of nutrients which include organic inorganic nutrients, compound amino acid and quick-acting, intermediate-acting and long-acting nutrients and can provide comprehensive nutrition, the fertilizer efficient of the fertilizer is long and stable, and the nutrients required by the whole growth period of the vegetables can be provided; the fertilizer contains rich organic matter and can improve the physical properties of soil, promote the activities of microorganisms and soil animals, increase the stress resistance of the vegetables and increase the fertilizer maintaining and supplying performance, and water-fertilizer integration is achieved.

Description

technical field [0001] The technical field of fertilizer production of the present invention relates to a vegetable multifunctional super-concentrated liquid organic-inorganic fertilizer and a preparation method thereof. Background technique [0002] In the 1960s, the fertilizers sold in the United States were mainly solid fertilizers, accounting for about 82% of the total sales, and liquid fertilizers accounted for 18%. By 2000, sales of solid fertilizers had fallen to 45 percent of the total, while liquid fertilizers had risen to 55 percent. The development and research of liquid fertilizers in my country began in the 1950s. Demonstration and promotion work was carried out in Beijing, Zhejiang, Shandong, Hebei, Guangdong, Xinjiang and other places in the 1970s. In 1980, the Xinjiang Land Reclamation Bureau began to use liquid ammonia to fertilize directly. By 1996, the accumulated fertilization area in 10 years exceeded 150,000 mu. my country is a big country in the pro...

Problems solved by technology

The disadvantages are: increasing the amount of fertilization will lead to soil pH imbalance, salinization, hardening, inhibiting the development of vegetable roots, weakening the function of water and fertilizer absorption, increasing the concentration of soil solution, reverse osmosis of vegetable plants, resulting in physiological wilting Or the leaf margins are scorched, sometimes producing toxic gas hazards

Fertilizers that are not absorbed seep into groundwater or enter rivers with surface runoff, causing pollution to water bodies and the environment; simply increasing the concentration of liquid fertilizers reduces the stability of fertilizers, is easy to settle, and has a low utilization rate; in order to improve the use of liquid fertilizers At present, the utilization rate is achieved by increasing the types of liquid fertilizers. Disadvantages: there are many types of fertilizers, the stability decreases, and the cost is high

Disadvantages: It is a special base fertilizer for peanuts. The utilization speed of the fertilizer is slow and the ingredients are many. It can only be made into solid fertilizer. The leftovers of monosodium glutamate are fermented together with other organic matter. The fermentation conditions are not easy to control, resulting in the production of harmful substances.

Disadvantages: Spray the fermenting bacteria on the surface of the granular fertilizer, fertilize the organic matter in the soil through the fermenting bacteria, the effect is slow, and the soil environment affects the fermentation of the fermenting bacteria

Disadvantages: direct use of MSG leftovers, strong acidity, and damage to the soil microenvironment
