The fertilizer provided by the invention adopts the common waste in agricultural production, like corn raw bran, rice husk, fungus residue and the like as the main raw materials, with the integrated formula, salt in saline-alkali soil can be absorbed effectively together.
Description
Technical field
The invention belongs to field of agricultural sciences, be specifically related to a kind of soil improvement fertilizer.
Background technology
Saltings refers to that salinity contained inside soil has influence on the normal growth of crop, and according to UNESCO and food and agricultural organization's incomplete statistics, the area in saltings, the whole world is 9.5438 hundred million hectares, and wherein China is 9,913 ten thousand hectares.China's saltings basicity is general higher, and serious salt affected soil regional plant almost can not be survived.At present, the improvement for saltings mainly comprises following method, first salt discharge, the desalinization of soil by flooding or leaching, reduction soil salt content; Plant the plant of Salt And Alkali Tolerance again, fertilizing soil; Last long-term cropping.Concrete ameliorative measure is: draining, and irrigate the desalinization of soil by flooding or leaching, warp improvement, rice cultivation, improvement of fostering and apply fertilizer, levels land and chemical modifying.But aforesaid method process is complicated, cost is high, and effect is not very good.
Summary of the invention
In view of the defect of above prior art, the invention provides a kind of alkaline land soil improving fertilizer.
According to the present invention, described alkaline land soil improving fertilizer mainly comprises: work in-process one 5-15 weight part, work in-process two 2-7 weight part, work in-process three 15-25 weight part, work in-process four 15-25 weight part, humic acid 8-12 weight part, clinoptilolite 8-12 weight part, vermiculite 3-8 weight part, magnesium sulfate 3-8 weight part, furfural dregs 12-17 weight part; Wherein,
Described work in-process one are fermented by sawdust and corn hair chaff to form;
Described work in-process two are formed through humic acid process by urea and ferrous sulfate;
Described work in-process three are that rice husk and animal excrement are fermented and formed;
Described work in-process four are that bacterium slag and animal excrement are fermented and formed.
According to one of embodiment of the present invention, the weight ratio of described sawdust and described corn hair chaff is 2-5: 1; Add biological humic acid microbial inoculum (BFA microbial inoculum) during fermentation, consumption is the 3-5% of sawdust weight.
BFA microbial inoculum ferments to stalk material (bagasse, wood chip or other straw powder) through extraordinary microorganism and the mixture of the fulvo acid (xanthohumic acid) that obtains and beneficial microorganism and other organic active substances.
In the present invention, sawdust refers to the sawdust of common deciduous tree, and corn hair chaff refers to the tankage after corn threshing.
Preferably, before described sawdust and described corn hair chaff ferment, the urea of gross weight 0.5-2% is added.
Test proves, adds appropriate urea, can regulate the carbon-nitrogen ratio of work in-process one, and then regulate the carbon-nitrogen ratio of soil improvement fertilizer before sawdust and the fermentation of corn hair chaff.
According to another embodiment of the present invention, the raw material of described work in-process two is urea 2-8 weight part, ferrous sulfate 1-4 weight part, humic acid 0.5-2 weight part.
According to the present invention's embodiment again, the raw rice husk of described work in-process three and the weight ratio of animal excrement are 0.5-2: 1.
Preferably, in the raw material of described work in-process three, animal excrement are cow dung, and the weight ratio of described cow dung and described rice husk is 1: 1.
Preferred further, during fermentation, maintenance moisture content is the 40-60% of rice husk and cow dung gross weight.
According to the present invention's embodiment again, the raw material bacterium slag of described work in-process four and the weight ratio of animal excrement are 2-3: 1.
Preferably, in the raw material of described work in-process four, bacterium slag is mushroom residue, and animal excrement are chicken manure, and the weight ratio of described mushroom residue and described chicken manure is 7: 3.
In the present invention, bacterium slag refers to the solid waste that is later left of the various edible mushrooms of cultivation, and edible mushrooms comprises the common edible mushrooms such as mushroom, straw mushroom, mushroom, auricularia auriculajudae, white fungus, wherein mushroom residue remaining waste material after referring to cultured mushroom.
According to the present invention, in described alkaline land soil improving fertilizer, also comprise the root-inducing powder of gross weight 0.3-1%.
Root-inducing powder can promote that farm crop take root in alkaline land soil, shortens rootage duration, improves rooting rate.
According to the preparation method of alkaline land soil improving fertilizer of the present invention for after work in-process one, work in-process two, work in-process three, work in-process four, humic acid, clinoptilolite, vermiculite, magnesium sulfate and furfural dregs are pulverized respectively, mix in proportion, to obtain final product.
The present invention adopts waste common in agriculture production, and if corn hair chaff, rice husk, bacterium slag etc. are main raw material, integrated formula, can effectively make a concerted effort to adsorb the salinity in saltings.Improving fertilizer of the present invention is particularly useful for the improvement in saltings, gardens.
