Multifunctional long-effect slow-release rice fertilizer

Abstract

The invention relates to a multifunctional long-effect slow-release rice fertilizer, which is prepared from urea, ammonium chloride, ammonium phosphate, calcium magnesium phosphate fertilizers, ordinary calcium superphosphate, potassium chloride, zinc sulphate monohydrate, high-activity organic matter, non-coating composite slow release agents, high-activity soil conditioning agents. The multifunctional long-effect slow-release rice fertilizer can promote the rice tillering; the rice spike number and the spike grain number can be emphatically increased, so that the yield is improved. Meanwhile, the absorption of the rice stems and seeds on N, P and K nutrients can be obviously improved; the fertilizer utilization rate is improved; the fertilizer consumption is reduced; meanwhile, the economic benefits of the rice are improved. By using the multifunctional long-effect slow-release rice fertilizer provided by the invention, the rice quality can be obviously improved; the obvious influence is particularly realized on fine rice rate, protein content and straight chain starch content.

Description

【Technical field】 [0001] The invention belongs to the technical field of agricultural fertilizers. More specifically, the present invention relates to a multifunctional long-acting slow-release rice fertilizer. 【Background technique】 [0002] At present, the main problems of rice fertilization are blind fertilization, biased fertilization, unreasonable fertilization, improper fertilization methods, etc. Specifically, (1) Heavy application of chemical fertilizers and non-application or light application of organic fertilizers will not only destroy the soil structure and The microbial community reduces the fertilizer supply capacity of the soil, and also affects the quality of rice; (2) Partial application of nitrogen fertilizer, heavy application of nitrogen fertilizer, less phosphorus and potassium fertilizer, and unreasonable ratio of nitrogen, phosphorus and potassium nutrients; (3) Medium and trace element fertilizer Seriously insufficient input, resulting in a serious i...

Problems solved by technology

[0002] At present, the main problems of rice fertilization are blind fertilization, biased fertilization, unreasonable fertilization, improper fertilization methods, etc. Specifically, (1) Heavy application of chemical fertilizers and non-application or light application of organic fertilizers will not only destroy the soil structure and The microbial community reduces the fertilizer supply capacity of the soil, and also affects the quality of rice; (2) Partial application of nitrogen fertilizer, heavy application of nitrogen fertilizer, less phosphorus and potassium fertilizer, and unreasonable ratio of nitrogen, phosphorus and potassium nutrients; (3) Medium and trace element fertilizer Seriously insufficient input, resulting in a serious imbalance of nutrient elements, frequent occurrence of physiological and infectious diseases, directly affecting the yield and quality of rice; (4) unreasonable fertilization, mainly due to improper fertilization methods, topdressing generally adopts spreading and surface application, Serious loss of fertilizer, low utilization rate; excessive fertilization, which not only reduces the utilization rate of fertilizer, but also slows the growth of rice due to lack of other nutrients. Many people promote the growth of rice by increasing the amount of urea application, not only Increased production costs, increased water and soil pollution, and increased the risk of lodging; unscientific fertilization, too much topdressing, and inaccurate timing of topdressing, resulting in the phenomenon of crazy growth in the early stage, premature closure and premature aging in the later stage

Unreasonable and unscientific fertilization will not only cause waste of fertilizers, decrease soil fertility, soil compaction and acidification, increase activity of heavy metals, increase production costs, but also cause agricultural environmental pollution, decrease the quality of agricultural products, and increase the safety risk of agricultural products

[0003] In recent years, compound fertilizers, compound fertilizers, formula fertilizers, etc. have been widely used, but because the national standards only make mandatory requirements for the three elements of nitrogen, phosphorus and potassium, and do not make any requirements for other nutrients and substances, therefore, the domestic market Compound fertilizers, compound fertilizers, and formula fertilizers generally have the following problems: (1) Most of them only have three nutrients: nitrogen, phosphorus, and potassium, and generally do not contain medium and trace elements and beneficial elements. The nutrients are pure and pure, and no other nutrients can be added at all; (2) no organic matter and humic acid are added, which will bring hidden dangers to soil fertility protection, sustainable development and agricultural product safety; (3) the formula is not very specific, often based on The cost determines the formula and ingredients; (4) Repeated fertilization, ordinary compound fertilizers have a short period of time, in addition to one base fertilizer, generally have to be topdressed several times. Severe pests and diseases, high-yield appearance but no high-yield harvest

[0004] In order to fundamentally solve the problems of blind fertilization, biased fertilization, unreasonable fertilization, and improper fertilization methods, there is an urgent need for a method that can achieve high and stable rice production, high quality and high efficiency, improve fertilizer utilization, rationally use resources, protect the ecological environment, and improve rice production. Special fertilizers for soil, soil fertility, and promotion of agricultural green development and sustainable development
