Abstract

A bioactivity potassium granulated fertilizer comprises a shell, a core wrapping layer and a core fertilizer. The core wrapping layer is a central wrapping layer and has a spherical body, the shell is arranged at the outer part of the core wrapping layer in a wrapping manner, and the core fertilizer is arranged in the core wrapping layer. The core wrapping layer is a degradable semipermeable membrane, the shell is also an active bacteria layer, and the core fertilizer is the fertilizer with active potassium granules. The active potassium granulated fertilizer is wrapped in the center, and is absorbed by plants in a controlled-release manner, so the utilization ratio of the chemical fertilizer can be better improved, and the loss of the chemical fertilizer can be reduced. The bioactivity potassium granulated fertilizer with a core-shell structure has a simple structure, and is convenient to use, low in production cost, and convenient to produce and popularize. The active bacteria stimulates potassium to be fully absorbed and non-exchangeable potassium to be absorbed; and the active factor, i.e. potassium can regulate the growth hormone (IAA) in the plants and gibberellin (GA) cytokinin (CTK).

Description

A kind of biological activity k particle fertilizer

Technical field

The utility model belongs to the chemical fertilizers production field, relates in particular to a kind of k particle fertilizer of biologically active.

Background technology

China is a large agricultural country, and agricultural is the basis of national economy.Modern agricultural development is a characteristic with low input, high production, high-level efficiency and sustainability.Chemical fertilizer industry and utilization thereof then are the important substance bases of modern agriculture production and development.According to Food and Argriculture OrganizationFAO (FAO) statistics, in the raising the output of developing country's grain, 55% effect from chemical fertilizer.Because factors such as volatilization, loss, infiltrations, in this season utilization ratio of China's chemical fertilizer, nitrogenous fertilizer is about 30-35%, and phosphate fertilizer is about 10-25%, and potash fertilizer is 35-50%, well below developed country's level.Low utilization rate of fertilizer not only causes enormous economic loss, but also can cause serious environmental to be polluted, the eutrophication of water body for example, and the farmland nitrogen is overflowed to the particularly influence etc. of ozonosphere of atmospheric layer, and then the health of human body has been constituted very big threat.Therefore, improve fertilizer utilization ratio, alleviate its pollution environment, develop sustainable, high-efficiency agriculture oneself through becoming the problem of the common concern in various countries.Potassium is " the article prime element " in N required in the plant growing process, P, the K three big key elements, and China's potassium ore resources is deficient.Increase along with the nitrogen phosphorus fertilizer consumption; The large scale application of high-yield variety and high-yield culture technique; Grain yield increases substantially; Crop is taken the potassium amount from soil also more and more, cause that the content of potassium descends year by year in the soil, and potassium becomes gradually and improves output and guarantee one of quality of agricultural product limiting factor.

The utility model content

The purpose of the utility model is, overcomes the weak point of prior art, and a kind of biological activity k particle fertilizer is provided, and is simple in structure, and convenient production has sustained release utility, potash fertilizer imitated be fully used.

The described a kind of biological activity k particle fertilizer of the utility model includes shell, core coated layer and core fertilizer.The core coated layer is the coating layer placed in the middle of the utility model, and integral body is spherical shape, and the outside of core coated layer is provided with shell with the form that coats, and the inside of core coated layer is a core fertilizer.The core coated layer of the utility model is a kind of degradable semi-permeable membranes, and shell also is a kind of active bacterium layer, and core fertilizer is the fertilizer that has active k particle.The utility model is coated on the center with active k particle fertilizer; Supplied plant absorbing with slowly-releasing; Can improve the utilization ratio of chemical fertilizer preferably, and can reduce the loss of chemical fertilizer, active bacterium promotes the abundant absorption of potassium and the absorption of non-exchangeable potassium; Active factor potassium can be regulated intravital growth hormone of plant (IAA) and Plant hormones regulators,gibberellins (GA) phytokinin (CTK).

The described a kind of biological activity k particle fertilizer of the utility model is a kind of biological activity k particle fertilizer of nucleocapsid structure, and simple in structure, easy to use, cost of manufacture is low, is convenient to produce and promote.The described a kind of biological activity k particle fertilizer of the utility model has improved the utilization ratio of chemical fertilizer greatly, and has reduced the loss of chemical fertilizer, and active bacterium promotes the abundant absorption of potassium and the absorption of non-exchangeable potassium; Active factor potassium can be regulated intravital growth hormone of plant (IAA) and Plant hormones regulators,gibberellins (GA) phytokinin (CTK).
