Description
Technical field
The present invention relates to agricultural biological technical field, be specifically related to a kind of preparation method of liquid biological activator, application.
Background technology
China has been chemical fertilizers production state maximum in the world.Although cultivated area is less than 10% of whole world total amount, the applying quantity of chemical fertilizer of China is close to 1/3 of world's total amount, and usage quantity occupies the whole world the 4th.The investigation display of the Chinese Academy of Agricultural Sciences in northern five 20 counties of province, the Nitrate content in ground water more than 50% in more than 800 points for investigation exceeds standard because of excessive use nitrogenous fertilizer, if this type of water source of long-term drinking will the figure of harm humans healthy.According to statistics, China is every year because unreasonable fertilising causes the nitrogen loss of more than 1,000 ten thousand tons outside farmland, and direct economic loss reaches 30,000,000,000 yuan.And life-time service chemical fertilizer also can cause soil property deterioration, deterioration in quality, peasant's fund input amount to strengthen year by year, Higher output is not accompanied by a higher income.Nearer next, in agriculture production, applying biological preparation progressively fertilizer for replacing chemical has become a kind of trend.Countries in the world, for all drawbacks of chemical fertilizer, have developed that a series of fertility is high, cost is low, pollution-free, biotechnological formulation to person poultry harmless.China also will progressively use bio-feritlizer fertilizer for replacing chemical, particularly will use biotechnological formulation as early as possible in the production of vegetables.
At present, biotechnological formulation product both at home and abroad containing humic acids is supplying raw materials of humic acids mainly with weathered coal, brown coal, peat or turfy soil greatly, its humic acids content range is generally at 40%-60%, and the biotechnological formulation impurity contained by all the other can bring impact greatly and burden to the shower nozzle of drip irrigation and sprinkling irrigation equipment in the use procedure of water soluble fertilizer.
Realize liquid manure one state, reach water-saving, economize the usefulness of fertile, saving of labor and volume increase, and this has become the development trend of industrialized agriculture.The liquid manure one state application percentage of the existing agricultural of China is less than 10%, and compared with adopting liquid manure one state technology with the U.S. more than 25%, Israel more than 90% agricultural, China relatively lags behind, and therefore domestic development prospect is still very wide.
Water soluble fertilizer is as a kind of readily avaiable fertilizer, and nutritive element is relatively comprehensive, and according to the nutrient uptake feature of Different Crop, corresponding fertilizer has different formulas, current domestic registration have 745 containing humic-acid kind Water soluble fertilizer.The special Water soluble fertilizer having all kinds of crops such as vegetables, fruit tree, flowers, grain, cotton, oils that market is sold.General consumption area mainly concentrates on the growing areas such as booth vegetable production base, production of fruit trees base and some flowers, and Liaoning of such as China, Hebei, Shandong, Xinjiang, Sichuan, Guangxi, the area such as Yunnan and Hainan are the emphasis consumption areas of Water soluble fertilizer.Although Water soluble fertilizer starts to walk soon at home, the requirement that Water soluble fertilizer product and application technique meet " low-carbon energy-saving, high-efficiency environment friendly ".
Current domestic solution continuous cropping problem, usually has a kind of mistaken ideas, and think that continuous cropping disease is a kind of disease by mistake, this understanding is worthless in fact.Continuous cropping disease is not a kind of disease causes only under many circumstances, is mostly that soil element lacks and is harmful to mushroom in soil and the disease that combined cause causes such as gathers.Solve continuous cropping problem, preferably supplement the scarce element of soil institute and root out soil and be harmful to mushroom and work along both lines, just can effectively be prevented and treated, but at present at home due to the medicine high cost of this dual activity, be difficult to the market recognition obtained, also almost do not have the medicine of this dual activity to occur.Therefore, when solving continuous cropping problem, the plot that should carefully analyze oneself is that nutritional deficiency disease is serious or disease serious, suits measures to local conditions, and selects the anti-continuous cropping series products be applicable to.
Summary of the invention
The present invention, in order to solve the weak point in above-mentioned background technology, provides a kind of preparation method of liquid biological activator, and its raw material added contains potassium fulvate and N, P
2o
5, K
2the macroelement such as O, not only can be used for improveing soil, can also avoid producing environment polluting, become and stablize and the agricultural biological preparation of comprehensive nutrition.The brown sugar added promotes the breeding of microorganism and improves its biological activity, has played product fertilizer efficiency better.Bulk composition used to be biological bacteria be gel-shaped series bacillus (Paenibacillus mucilaginosus preserving number CGMCC1.3714) fermentation expands numerous after liquid formulation, it has multiple biological activity, is of value to agriculture production.A kind of liquid biological activator can be applied to the industrialized agricultures such as spray drop filling, and the rapid dissolving of fertilizer significantly can improve the specific absorption of crop.A kind of liquid biological activator can improve quality of vegetable, output, and has anti-continuous cropping, disease resistance, anti-saline and alkaline and improvement soil equivalence fruit.
for achieving the above object, the technical solution used in the present invention is:
A preparation method for liquid biological activator, its special character is to comprise following operation steps:
