Description
【Technical field】
The present invention relates to technical field of fertilizers, and in particular to a kind of sweet potato fertilizer and preparation method thereof.
【Background technology】
In present agricultural production, inorganic fertilizer is in occupation of most of market, but inorganic fertilizer has greatly not enough and defect,
It is mainly manifested in the following aspects:
One, destroys soil, causes soil organic matter content to decline, and all kinds of nutrients ratio imbalances, soil starts acidifying, plate
Knot, the physicochemical property and soil microflora of soil is caused its water conservation, fertilizer conservation and poor air permeability by heavy damage, difficult
To meet the actual growth needs of crops;
Two, crops are strong to the dependence of fertilizer and pesticide, it is necessary to increase usage amount year by year, and otherwise crop growth is slow,
Disease and insect is serious, causes the underproduction;
Three, agroecological environments deteriorate, and chemical fertilizer is applied behind farmland, and practical efficiency only has 30%, and major part is arranged with farmland
Water is flowed into and rivers and lakes or residued in soil and crops, not only bring environmental pollution but also crisis human life safety and
Health, these are all by the obstacle as agricultural sustainable development.
And sweet potato is rich in protein, starch, pectin, cellulose, amino acid, vitamin and several mineral materials, there is " longevity food
The reputation of product ", it has the effects such as anticancer, cardioprotection, prevention pulmonary emphysema, diabetes, fat-reducing, is a kind of food that people like
Thing.And fertilizer used in sweet potato plantation at present is generally inorganic fertilizer, this and its sustainable development beneficial to agricultural and the mankind
Health, it would therefore be desirable to which one kind can long-acting volume increase and noresidue, free of contamination sweet potato fertilizer.
【The content of the invention】
The goal of the invention of the present invention is:For above-mentioned problem, there is provided a kind of sweet potato fertilizer and preparation method thereof.
The sweet potato fertilizer of the present invention has long-acting volume increase, noresidue, free of contamination feature, and its preparation method is simple, easy to implement, into
This is low, with preferable popularizing application prospect.
To achieve these goals, the technical solution adopted by the present invention is as follows:
A kind of sweet potato fertilizer, includes the raw material components of following parts by weight:40-50 parts of turf, 30-40 parts of sugarcane bagasse, biology
10-20 parts of charcoal, 10-20 parts of potassium fulvate, 10-15 parts of kaolin, 5-15 parts of urea, 1-3 parts of mannitol, sodium molybdate 0.3-0.7
1-3 parts of part and composite bacteria;Wherein, colloid bacillus cereus, phosphorus decomposing pseudomonad, rhizobium and small are contained in the composite bacteria
Streptomyces aureus.
Further, the sweet potato fertilizer includes the raw material components of following parts by weight:45 parts of turf, 35 parts of sugarcane bagasse, life
2 parts of 15 parts of thing charcoal, 15 parts of potassium fulvate, 13 parts of kaolin, 10 parts of urea, 2 parts of mannitol, 0.5 part of sodium molybdate and composite bacteria.
Further, hundred million/g of colloid bacillus cereus 3-4, hundred million/g of phosphorus decomposing pseudomonad 2-3, root are contained in the composite bacteria
Hundred million/g of knurl hundred million/g of bacterium 1-3 and streptomyces microaureus 1-3.
Further, a kind of preparation method of sweet potato fertilizer, including step in detail below:
(1) by weight, turf, sugarcane bagasse, charcoal and kaolin are weighed, by the turf weighed, sugarcane bagasse, life
Thing charcoal and kaolin co-grinding and 50 mesh that sieve, are placed under 150-160 DEG C of steam after sterilizing 15-20min, are cooled to
30-35 DEG C, crushed material is obtained, it is standby;
(2) by weight, mannitol, sodium molybdate and composite bacteria are weighed, by the mannitol weighed, sodium molybdate and multiple
After conjunction strain is mixed to uniformly, add distilled water and continue to mix to uniformly, obtain mixture;By the mixture with it is upper
State crushed material to mix to after stirring, in stacking 35-40h at 35-40 DEG C, obtain fermentate, it is standby;
(3) by weight, potassium fulvate and urea are weighed, and the potassium fulvate weighed and urea is added to above-mentioned
Mixed in fermentate uniformly, then pelletized, dried, you can obtain the sweet potato fertilizer of the present invention.
Further, in step (2), the water content of the mixture is 20-25%.
Further, in step (3), the water content of the sweet potato fertilizer is less than 7%.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows:
(1) present invention targetedly adds the potassium content in fertilizer and correspondingly reduced according to the uptake characters of sweet potato
Each raw material components in nitrogen content and phosphorus content, and fertilizer cooperate, and have sweet potato fertilizer of the invention nutritious
Comprehensively the characteristics of, it is more beneficial for promoting the growth of sweet potato, and then reaches the purpose of volume increase.Further, sweet potato of the invention fertilizer
In the raw material of material, the rubbish of agricultural crops is taken full advantage of, while with the use of special composite bacteria, not only turn waste into wealth,
Can be as the good source of manure of sweet potato, and be also good soil conditioner, composite bacteria therein not only can for a long time effectively
The active ingredient decomposed in sweet potato fertilizer or in soil, but also can be to sweet potato so as to provide various nutrient elements to sweet potato
Offer is substantial amounts of and is a variety of physiologically active things such as amino acid, vitamin, growth hormone and antibiotic necessary to sweet potato growth
Matter, can effectively reduce the root insect pest of sweet potato.Wherein, in turf, sugarcane bagasse, charcoal and the kaolin in sweet potato fertilizer not only
Containing abundant nutriment, and can as composite bacteria carrier, and add sodium molybdate can improve above-mentioned carrier pair
The suction-operated of composite bacteria, meanwhile, the mannitol of addition can provide nutriment for the growth of composite bacteria, therefore, with
Upper component collective effect, can effectively improve the survival rate for bringing back to life strain, so as to improve the using effect of composite bacteria of the present invention.It is comprehensive
Upper described, each raw material components interaction in sweet potato fertilizer of the present invention can have long-acting volume increase, noresidue, free of contamination
Feature, the health of sustainable development and the mankind beneficial to agricultural.
(2) sweet potato method for preparing fertilizer of the invention is simple, easy to implement, and cost is low, before preferable popularization and application
Scape.
