Abstract

The invention discloses a rare-earth-containing modified bamboo fiber coated fertilizer for strawberry. The invention is characterized in that the fertilizer is prepared from the following raw materials in parts by weight: 21-26 parts of fine-granularity magnesite, 32-37 parts of blast furnace slag, 2-3 parts of lanthanide-series rare earth, 18-21 parts of urea, 3-5 parts of calcium magnesia phosphate fertilizer, 0.1-0.2 part of phytase, 0.02-0.03 part of silicate bacterium, 0.5-1.0 part of lentinan, 20-24 parts of nitrophospate, 21-26 parts of liquid ammonium phosphate, 12-15 parts of potassium chloride, 8-11 parts of modified bamboo fiber, 2-5 parts of nano carbon, 1-3 parts of zinc sulfate, 0.2-0.5 part of potassium polyacrylate, 1-2 parts of selenium chloride, 0.4-0.9 part of boric acid, 0.1-0.4 part of silane coupling agent KH550 and a right amount of water. The lanthanide-series rare earth is added to the fertilizer to promote the photosynthesis of strawberry, enable the root system to grow and develop and to absorb nutrients, and enhance the stress tolerance; and the added modified bamboo fiber has the functions of protecting the soil quality and loosening the soil, has the effects of postponing the degradation time and improving the moisture and fertility preservation capacity of soil, and lowers the soil-borne diseases of soil due to the natural antimicrobial property of the bamboo fiber, thereby providing a favorable growth environment for growth of strawberry and enhancing the quality and grade of strawberry.

Description

A kind of strawberry modified bamboo fibers encapsulation fertilizer containing rare earth element and preparation method thereof

Technical field

The present invention relates to fertilizer field, particularly a kind of strawberry modified bamboo fibers encapsulation fertilizer containing rare earth element and preparation method thereof.

Background technology

Rare earth element is the group element being arranged in the periodic table of elements the IIIth B race, because rare earth element enriches, China scientific and technical personnel start rare earth very early in research and development agriculturally, research proves, solubility salt rare earth is adopted to be equipped with suitable concentration of aqueous solution, being applied to various farm crop and all can obtaining effect of increasing production in various degree of timely and appropriate discovery, and the quality effect of crop can be improved.The effect of rare earth element shows enhancing photosynthesis, effectively promotes leaf growth, the thick obvious increase of Ye Chong, leaf area and leaf, and chlorophyll content in leaf blades increases; The rare earth element of appropriate concentration also can promote growing of crop root, improve improving activity of root system, promote Furcation defects and Metabolic activity, it is more that radical showed increased, root length rises appreciably, root brings up again height, thus improve the absorption of root to the nutrient substances such as N, P, K and moisture, promote the growth of crop field upper part, plant increases, and tillers or branch increases; By giving facts have proved of crop applying rare earth, crop can resist the impact of unsuitable environmental condition in the living environment of complexity, strengthens greatly the resistivity of the impact of the poor environments such as salt marsh, arid, low temperature; Improve heavy metal content and raising food safety etc. in crop yield, oil recovery enhancement and reduction agricultural-food and have good action, rare earth and other agricultural chemicals more remarkable with the use of effect, these agricultural chemicals have lot of advantages: nontoxic to people and animals, noresidue, do not affect fertilizer efficiency drug effect; After being decomposed by soil microorganisms, not only do not pollute the environment, the amino acid produced after decomposing and lipid acid etc. as nutritive substance, can also improve the quality of soil and farm crop.Rare earth also has good prophylactic effect to the disease of crop.

Bamboo fibers utilizes natural bamboo for raw material, and the regenerated cellulose fibre produced through special high-tech art breading is the fifth-largest natural fiber after cotton, fiber crops, hair, silk.Bamboo fibers have good ventilation property, moment the characteristic such as water-absorbent, stronger wear resistance and good dyeability, have again simultaneously natural antibacterial, antibacterial, except mite, deodorization and anti-ultraviolet function.Bamboo fibers is wide material sources on starting material, and usability is strong, is mainly manifested in the bamboo grows phase short, can become a useful person in 2-3 and once plant long-range business, and natural degradation in soil, after decomposition to environment without any pollution, be a kind of raw material that is natural, green, environment-friendly type.

Summary of the invention

The object of this invention is to provide a kind of strawberry modified bamboo fibers encapsulation fertilizer containing rare earth element and preparation method thereof.

In order to realize object of the present invention, the present invention is by following scheme implementation:
