Background technology
China has consumed the chemical fertilizer in the whole world 35% on the arable land that accounts for the world 7%, the fertilizer amount of unit cultivated area be the world average more than 3 times, utilising efficiency is about 35%, is merely the half the of developed country.Clay fertilizer institute of the Chinese Academy of Agricultural Sciences (2010) investigation result, existing 17 the average amounts of application of province's nitrogenous fertilizer of China surpass internationally recognized upper limit 225kg/hm2.Chemical fertilizer in the agriculture prodn is excessive to be used, and not only causes utilization rate of fertilizer low, and production cost strengthens; The arable land soil fertility descends; More serious is to cause environmental pollutions such as water body, soil and atmosphere, influences agricultural product quality and safety, jeopardizes the healthy of consumers in general." pollution by chemical fertilizer " phenomenon has become people's common recognition.
On tobacco planting, cigarette descends with utilization rate of fertilizer year by year; The vegetation that the vega contiguous plant causes is gone down, the increasing the weight of year by year of the minimizing of natural species and natural enemy, tobacco disease insect pest; The excessive of indiscriminate use of pesticide and chemical fertilizer used, and soil organism input is reduced, and causes the soil microbial population imbalance, and the quality of tobacco that causes planting out reduces, and output reduces, a series of problems such as planting benefit downslide and environmental pollution,
The tobacco planting family is badly in need of a kind of simple, and is with low cost, improves yield of tobacco and first-class cigarette ratio, increases the technology and the method for the tobacco leaf output value.
Summary of the invention
The purpose of this invention is to provide grow tobacco a microbial organic fertilizer prescription and a method of manufacture thereof, the present invention can reduce 30%-50% composite fertilizer usage quantity, improves the soil, and effectively improves yield of tobacco and first-class cigarette ratio, and simple, with low cost.
For realizing above-mentioned purpose, the technique means that the present invention adopts is:
One grow tobacco microbial organic fertilizer prescription and method of manufacture thereof, its prescription is (by weight):
Soya-bean cake fermented product 30-50 part, subtilis (15,000,000,000/gram) microbial inoculum 0.2-1 part, humic acid 49-69.8 part.
The method of manufacture of this prescription is following:
After soya-bean cake pulverized, place rotation to steam in material (whether wrongly written character) pot, add the moisture of 20%-25%; Steamed 45-50 minute, and be cooled to then below 45 ℃, obtain the soya-bean cake fermented product; Get soya-bean cake fermented product 30-50 part, the adding subtilis (15,000,000,000/more than the gram) microbial inoculum 0.2-1 part, rotation stirs; Be put in the solid-state fermentation tank, aerobic fermentation is 48 hours under 38 ℃ of conditions, is being dried to moisture content below 45 ℃ below 15% then; Be crushed to below 300 orders, add humic acid 49-69.8 part mixing granulation, the granulation process temperature is controlled at below 45 ℃; After granulation finishes, be lower than drying under 45 ℃ of environment, be lower than 15% to moisture content and can obtain this prescription tobacco microbial organic fertilizer in temperature.
Action principle:
Formulation product of the present invention is a kind of fertilizer slow-release formulation; It is again a kind of urease inhibitor; Can be through mix the complex body that forms the another kind of fertilizer of parcel with one or more nutritive substances; The humic-acid kind urease inhibitor is a kind of area synergist of environmental protection, can increase crop yield, improves crop quality.Still be a kind of good microorganism growth base-material simultaneously; Can improve the prolificacy of mikrobe; Thereby make mikrobe can absorb fixing more inorganic states nutrient and be retained in the soil with the form of organic nutrient; Constantly satisfy the needs of plant growth, reduce the fertilizer loss that causes because of leaching and volatilization; Multiprenylmenaquinone can improve light and the ability of plant, thereby increases the demand of plant to nutritive substance, promotes the active absorption of plant to fertilizer; Can promote the absorption of mikrobe to calcium; Strengthen the survival and reproduction ability of mikrobe under the high osmotic pressure environment; High resistance to cold and diseases mikrobe combination contains 8 kinds of microorganism species, under the high osmotic pressure environment of using with composite fertilizer, living bacteria count still can reach 2,000 ten thousand/more than the g.
Beneficial effect of the present invention is: soya-bean cake and humic acid both can provide direct nutritive substance to tobacco, promoted cigarette strain growth, can improve quality of tobacco and utilization rate of fertilizer again; Subtilis can be improved utilization rate of fertilizer, and its secretory product has the raising effect to cigarette strain growth and quality of tobacco; Three kinds of raw materials are produced by this prescription, simple, with low cost, can effectively improve yield of tobacco and first-class cigarette ratio, increase the tobacco leaf output value; Mix use with composite fertilizer, reduce composite fertilizer usage quantity 30%-50%, microorganism species has effectively been improved soil physical property.
