Abstract
The invention provides a multifunctional compound fertilizer which comprises nitrogen, phosphors, potassium and magnesia; and the content of the magnesia is between 6 and 10 percent. According to proportion, 11.8 percent of caustic magnesite powder and 3.5 to 7.6 percent of sepiolite and a biomass caking agent are mixed with the compound fertilizer; or the caustic magnesite powder, zeolite and the biomass caking agent are mixed to make the mixed product contain 7.1 percent of the caustic magnesite powder and 4.8 to 6.2 percent of the zeolite and the biomass caking agent. The multifunctional compound fertilizer can solve the problems that the red soil in South China lacks a magnesium element so as to cause the reduction of crop yield, can improve physicochemical property and micro-entironment of soil and remarkably increase the yield and quality of the crop.
Description
Technical field
The present invention relates to a kind of composite chemical fertilizer, more particularly, relate to and contain nitrogen, phosphorus, kalium multielement, multi-functional composite chemical fertilizer.
Background technology
The composite fertilizer that generally uses in agriculture production is to contain two or three in nitrogen, phosphorus, three kinds of elements of potassium, though this class composite fertilizer is applicable to the farm crop that grow in all kinds of soil, but can not or be difficult to satisfy the needs of plant growth on the special soil type, particularly be difficult to satisfy the needs of plant growth on low fertility red soil nonirrigated farmland.Magnesium is one of necessary element of crop growth, is to form unique mineral nutrient element in the chlorophyll molecule, and still be the activator of many enzymes such as phosphokinase etc. simultaneously, be listed in the fourth-largest essential element of the plant that is only second to nitrogen, phosphorus, potassium element.In the Red Soils in Southern China area, be subjected to high temperature, envrionment conditions and the influence of various factors of soil own such as rainy, magnesium elements in the soil is easy to lose because of migration and leaching, output reduces, low quality because of magnesium deficiency makes to cause farm crop, and this phenomenon shows particularly evident in the red soil dry crop.About 200,000,000 mu of Red Soils in Southern China nonirrigated farmland area, this part nonirrigated farmland is the important leverage of southern agricultural sustainable development and increasing peasant income, guarantee that dry crop continues volume increase, the plain nutrition of necessary Mg supplementation, therefore, use and contain the key that the magnesium chemical fertilizer has become red soil dry crop good quality and high output.At present, domestic yet there are no can increase the plain nutrition of magnesium but not increase the production and selling cost and have the technology record of the character function composite fertilizer that improves the soil.
Summary of the invention
Technical problem to be solved by this invention provides a kind of multifunctional compound fertilizer, can Mg supplementation by making it contain magnesium oxide plain nutrition, and can improve soil physico-chemical property and soil micro-ecosystem environment.
In order to solve the problems of the technologies described above, the invention provides a kind of multifunctional compound fertilizer, except that containing nitrogen, phosphorus, three kinds of elemental compositions of potassium, also contain magnesium oxide and biological material in the described composite fertilizer.
Preferably, the content of magnesia in the described composite fertilizer is 6% to 10%.
Preferably, will contain that magnesian light burnt powder accounts for 11.8%, the ratio of sepiolite and biomass tackiness agent 3.5% to 7.6% mixes with composite fertilizer.
Preferably, will have contain that magnesian light burnt powder accounts for 7.1%, the ratio of zeolite and biomass binder constitutes 4.8% to 6.2% mixes with composite fertilizer.
Preferably, the nitrogen of composite fertilizer, phosphorus, potassium element total content equal 25% at least.
Preferably, the nitrogen element content in the composite fertilizer is less than or equal to 18%.
Preferably, the phosphorus element content in the composite fertilizer is less than or equal to 9%.
Preferably, the potassium element content in the composite fertilizer is less than or equal to 18%.
Adopt multifunctional compound fertilizer provided by the invention, owing to contain magnesium oxide and regulate the materials such as sepiolite, zeolite and biomass of soil property, thereby be China south big area red soil dry crop produces, soil improvement provides agricultural sustainable development and increased income important leverage.
