Description

It is a kind of The preparation method of vega soil modifying agent

Technical field

The present invention relates to technical field of land improvement, more particularly to a kind of preparation method of vega soil modifying agent.

Background technology

At present, in south China, the situation of soil acidification is increasingly severe, particularly plants the vega of tobacco leaf, and more so, soil acidification is a kind of form of expression of soil degradation to its acidifying situation, refers to that soil acidification increases, and is changed into highly acid or a kind of extremely strong acid natural phenomena.China's soil acidification situation is increasingly severe, the land area of acidifying has been expanded to more than the 40% of China's cultivated area, and often have the situation of generation in blocks, particularly in south China, due to soil slant acidity in itself, rainwater is again more, and soil acidification phenomenon is more serious, the soil acidification or severe acidification about more than 70% of Hunan area.Vega rate of fertilizer is big, and more using physiological phenomenon fertilizer, the acidifying problem of vega soil is more protruded than general arable land, and soil acidification causes the plant recovery of nutrient to reduce, and the increase of soil harmful levels of pathogens directly affects the yield and quality of tobacco leaf.

The method of convention acidic soil improvement is individually that with lime or agstone, liming can significantly be such that the acidity of acid soil reduces, but make multiple acidizing degree reinforcement sometimes.In the market also has some acid soil composite modifying agents, main component is the mixture of lime and some mineral or industry byproduct, but most of in these modifying agents contain a certain amount of poisoning metal element, such as lead, cadmium, arsenic, chromium, there is the pollution problem to soil environment.

The content of the invention

The technical problem to be solved in the present invention is to provide a kind of preparation method of vega soil modifying agent, and the vega soil modifying agent prepared by the method is with low cost and does not result in soil pollution.

In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：A kind of preparation method of vega soil modifying agent, comprises the following steps：The first step, prepare calcium carbonate powder：Paris white is broken to the fineness degree of 50 mesh；Second step, prepare fermentation soybean stalk particle：First soybean stalk is crushed by pulverizer, then the soybean stalk crushed is fermented under conditions of 40 degrees Celsius and is cured 20 days, be dried again to water content after soybean stalk drying to water content 4-4.5%, the granulation of the curing that will then ferment and be less than 2%；The Paris white obtained in 3rd step, the fermentation soybean stalk particle and the first step that will be obtained in the charcoal powder of 80 mesh, saccharomycete, bacillus subtilis, potassium fulvate, potassium sulfate, second step mixing and stirring at normal temperatures, the vega soil modifying agent is can obtain, the weight proportion of above-mentioned each component is：20 parts of the Paris white of 50 mesh, 15 parts of the calcium hydroxide powder of 50 mesh, 72 parts of fermentation soybean stalk particle, 13 parts of the charcoal powder of 80 mesh, saccharomycete 0.01-0.015 parts, bacillus subtilis 0.008-0.013 Part, 2 parts of potassium fulvate, 9 parts of potassium sulfate.

The present invention obtain beneficial effect be：It is primary raw material that the preparation method of the vega soil modifying agent that the present invention is provided uses calcium carbonate, calcium hydroxide, fermentation soybean stalk particle, calcium carbonate south China knob generally existing, cheap, easy acquisition；Simultaneously, using fermentation soybean stalk particle as the raw material of soil conditioner can not only effectively alleviate because partially to fertilize caused by soil acidification situation, the retain water and nutrients ability of soil can also be improved and crop straw burning can be avoided to pollute the situation of air, in addition, the present invention is by adding charcoal powder, saccharomycete, bacillus subtilis and potassium fulvate, further improve soil granular structure, loose soil, improve the retain water and nutrients ability of soil, so as to be conducive to crop root to develop, be conducive to improving the growing state of tobacco leaf in acidified soil, heavy metal element without contaminated soil in above-mentioned raw materials, the feature of environmental protection is good.

Specific embodiment

Used as one embodiment of the present invention, a kind of preparation method of vega soil modifying agent is comprised the following steps：The first step, prepare calcium carbonate powder：Paris white is broken to the fineness degree of 50 mesh；Second step, prepare fermentation soybean stalk particle：First soybean stalk is crushed by pulverizer, then the soybean stalk crushed is fermented under conditions of 40 degrees Celsius and is cured 20 days, be dried again to water content after soybean stalk drying to water content 4-4.5%, the granulation of the curing that will then ferment and be less than 2%；The Paris white obtained in 3rd step, the fermentation soybean stalk particle and the first step that will be obtained in the charcoal powder of 80 mesh, saccharomycete, bacillus subtilis, potassium fulvate, potassium sulfate, second step mixing and stirring at normal temperatures, the vega soil modifying agent is can obtain, the weight proportion of above-mentioned each component is：20 parts of the Paris white of 50 mesh, 15 parts of the calcium hydroxide powder of 50 mesh, 72 parts of fermentation soybean stalk particle, 13 parts of the charcoal powder of 80 mesh, saccharomycete 0.01-0.015 parts, bacillus subtilis 0.008-0.013 Part, 2 parts of potassium fulvate, 9 parts of potassium sulfate.

The application method of above-mentioned vega soil modifying agent is：First vega soil is ploughed shallowly scarifying, then soil conditioner is sprinkled upon in soil, deep ploughed afterwards, soil conditioner is buried into soil, finally compoiste fertilizer and covered with shallow soil on soil surface is applied.If wanting further to improve the yield of tobacco leaf and increasing the thickness of blade, can be in tobacco leaf growth course, the pouring root after two weeks adds 0.15 part of latting drown of 1 part of soil conditioner and rare earth with 100 parts of water, until tobacco leaf harvesting is first 1 month.

It is primary raw material that the preparation method of the vega soil modifying agent that above-mentioned implementation method is provided uses calcium carbonate, calcium hydroxide, fermentation soybean stalk particle, calcium carbonate south China knob generally existing, cheap, easy acquisition；Simultaneously, using fermentation soybean stalk particle as the raw material of soil conditioner can not only effectively alleviate because partially to fertilize caused by soil acidification situation, the retain water and nutrients ability of soil can also be improved and crop straw burning can be avoided to pollute the situation of air, in addition, the present invention is by adding charcoal powder, saccharomycete, bacillus subtilis and potassium fulvate, further improve soil granular structure, loose soil, improve the retain water and nutrients ability of soil, so as to be conducive to crop root to develop, be conducive to improving the growing state of tobacco leaf in acidified soil, heavy metal element without contaminated soil in above-mentioned raw materials, the feature of environmental protection is good.

Above-described embodiment is the present invention preferably implementation, and in addition, the present invention can be realized with other manner, and any obvious replacement is within protection scope of the present invention on the premise of the technical program design is not departed from.

Finally, it should be emphasized that, in order to allow those of ordinary skill in the art more easily to understand improvements of the present invention relative to prior art, some descriptions of the invention have been simplified, and for the sake of clarity, present specification is omitted some other elements, and those of ordinary skill in the art should be aware that these elements for omitting also may make up present disclosure.
