Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to an organic fertilizer for improving attapulgite ecological soil.
Background
Along with the rapid development of modern intensive agriculture in China, the long-term unreasonable use of a large amount of inorganic fertilizer gradually destroys the soil structure of farmland, changes the physicochemical property of soil, causes soil hardening and degeneration, and the yield increasing effect of the fertilizer is less and less obvious, thereby causing the yield and quality of crops to be reduced, and exogenous pollutants enter animals and human bodies through water, atmosphere and food chains in a circulating manner, thereby harming the health of people and livestock, and causing cancers or chronic diseases and the like.
The attapulgite clay is a clay mineral containing attapulgite as main component. The attapulgite is a crystalline hydrated magnesium aluminum silicate mineral, has unique layer chain structure characteristics, has lattice displacement in the structure, contains variable amounts of Na +, Ca2+, Fe3+ and Al3+ in the crystal, and is in a needle shape, a fiber shape or a fiber aggregation shape. The attapulgite has good colloidal properties of unique dispersion, high temperature resistance, salt and alkali resistance and the like and higher adsorption decoloring capacity. And has certain plasticity and adhesive force and an intermediate structure between the chain structure and the layered structure. The attapulgite is produced in sedimentary rock and weathering crust in the form of soil and dense block, and has white, off-white, grey-green or weak-silk luster. The soil is fine and smooth, has a greasy feeling, is light and crisp, has shell-shaped or ragged fracture and strong water absorption. Has viscosity and plasticity when wet, shrinks less after drying, does not show cracks greatly, and is soaked in water to be disintegrated. The suspension does not flocculate and precipitate when it encounters a dielectric medium. As the binder of the compound fertilizer, the compound fertilizer has the advantages of high granulation forming rate, short time, high strength of the produced granules, good surface smoothness and long fertilizer retention time, so the binder can improve the production capacity. The fertilizer synergist produced by using the attapulgite can fully provide fertilizer guarantee for developing green ecological agriculture. In view of the above, we propose an attapulgite ecological soil improvement organic fertilizer to solve the above problems.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the technical defects and provides the organic fertilizer for improving the attapulgite ecological soil.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: an attapulgite ecological soil improvement organic fertilizer comprises a framework part of the organic fertilizer, and is characterized in that: the attapulgite organic fertilizer cake comprises a funnel barrel, an attapulgite organic fertilizer cake, a soil inserting rod and a compound fertilizer sphere, wherein the attapulgite organic fertilizer cake comprises a cake groove and a cake shoulder; the attapulgite organic fertilizer cake is prepared by uniformly mixing jute fiber and natural attapulgite mineral material powder in a certain proportion, and pressing into plum blossom-shaped cake blocks by a set mould and a hydraulic press; the plum blossom shape is characterized by comprising the following components: the cake grooves and the cake shoulders are arranged at intervals, and the cake grooves are used for placing and fixing compound fertilizer spheres; the soil inserting rod is connected to one side of the funnel barrel, a water replenishing pipe is arranged in the soil inserting rod, one end, away from the funnel barrel, of the soil inserting rod is connected with a water receiving funnel, and a plurality of water guide pipes are obliquely inserted into the side wall of the soil inserting rod; a degradable pipe plug is arranged inside the connecting end of the water replenishing pipe and the funnel barrel, and a plurality of capillary tubes penetrate through the pipe plug;
