Abstract

The invention relates to a method for preparing organic fertilizer with eucalyptus bark and leaves as raw materials. In the organic fertilizer, the content of wood raw materials such as bark and leaves is up to 70-90%, and the use of other miscellaneous materials is greatly reduced. The method of the invention has the advantages of less auxiliary materials are used, and the preparation is convenient.

Description

It is a kind of that to take mallee bark and leaf be the method that raw material is made organic fertilizer

Technical field:

The invention belongs to the making method of the organic fertilizer in biological chemical fertilizer making field, what be specifically related to is that a kind of to take mallee bark and leaf be the method that raw material is made organic fertilizer.

Background technology:

The trunk of existing eucalyptus is mainly used to make paper, and for the other materials outside trunk, as bark and leaf, owing to need not being applicable to for making paper, tends to be simply discarded or let alone oneself corruption, has caused serious waste.And at present in agriculture production due to extensive a large amount of chemical fertilizer that use, cause soil compaction, land fertility descends, the crop and fruit hypotrophy.If not in time soil is improved, soil can finally lose crop growth power, and agricultural is brought about great losses.How can soil be improved, to reduce the fertilizer application amount, be to need at present the problem solved, and a way is exactly the use that increases the fertilizer bio-fertilizer, and biological organic fertilizer does not burn root, not rotten seedling, can promote the utilization ratio of chemical fertilizer, the stable soil nutrient.Life-time service can make soil soft, and organism quantity increases, and crop and fruit comprehensive nutrition, abundant, bring many benefits to growing of the mankind.So a kind of chemical fertilizer method of forest tree castoff as the main raw material making of take occurred adopting, as Chinese patent 98101308.2, but it only contains 10～70 forest tree castoff, needs to add other more assorted material, the demand of subsidiary material is larger, and practical application is poor.

Summary of the invention:

The defect existed for prior art, the purpose of this invention is to provide a kind of take mallee bark and leaf that can overcome above-mentioned defect is the method that raw material is made organic fertilizer.

The present invention solves the technical scheme that its technical problem takes: a kind of to take mallee bark and leaf be the method that raw material is made organic fertilizer, and described method comprises the following steps:

1): the mallee bark that is 20～40% by mass dryness fraction and the mixture of leaf are ground into 20～60 broken ends of purpose;

2): make the fermentation parent: the zymophyte and the rice bran that by weight ratio, are 1: 10 evenly mix;

3): be ground into 10～50 broken ends of order after animal excrement are dried:

4): by the article in above-mentioned 1,2,3 steps according to weight ratio: 70～90: 1～3: 7～27, evenly mix;

5): the mixture that above-mentioned steps is obtained adds water, makes its water ratio reach 60～65%;

6): the mixture that above-mentioned steps is obtained carries out windrow;

7): covered with plastic film control temperature in bank with plastics film outside bank;

8): carry out fermentation step: the temperature of controlling in bank is spent 30～35, and maintain 30-60 days, when plastics film to the air-proof condition of bank constant and in heap temperature start to lower, and occur that ammoniacal liquor distinguishes the flavor of and/or wine flavour, in the adularescent mycelia, finish fermenting process in heap simultaneously;

9): the bank after fermentation is spread out, dried to moisture≤30%.

Described step 6) carry out the length of the bank of windrow in: wide: height is 5 meters: 5 meters: 2 meters.

Described step 8) the leavening temperature scope in is 15～70 degrees centigrade, when the temperature of bank, higher than 65 degrees centigrade the time, need to carry out the turning step.

Described step 8) pH value in will be controlled between 6.5～8.5.

Wood raw material in of the present invention, as the content of bark and leaf etc. reaches 70～90%, greatly reduced usage quantitys of other assorted material, has less, the easy to make advantage of the auxiliary material of use.

The accompanying drawing explanation:

Fig. 1 is fermentation process schema of the present invention

Embodiment:

A kind of to take mallee bark and leaf be the method that raw material is made organic fertilizer, and described method comprises the following steps:

1): the mallee bark that is 20～40% by mass dryness fraction and the mixture of leaf are ground into 20～60 broken ends of purpose;

2): make the fermentation parent: the zymophyte and the rice bran that by weight ratio, are 1: 10 evenly mix; Zymophyte in this step is the bark zymophyte that sell market;

3): be ground into 10～50 broken ends of order after animal excrement are dried: described animal excrement comprise the ight soil such as chicken manure, pig manure, duck excrement, pigeon dung, human excrement; Three above-mentioned steps are sequentially built in no particular order;

4): by the article in above-mentioned 1,2,3 steps according to weight ratio: 70～90: 1～3: 7～27, evenly mix;

5): the mixture that above-mentioned steps is obtained adds water, makes its water ratio reach 60～65%; 60～65% water ratio can make fermentation more smooth.Can also add with ammoniacal liquor in this step, increase ammonia-nitrogen content in mixture, improve fermentation efficiency.

6): the mixture that above-mentioned steps is obtained carries out windrow;

7): covered with plastic film control temperature in bank with plastics film outside bank; When temperature is higher, raise film, allow waste heat shed, when temperature reduces, pack tightly film, to improve inner heat.

8): carry out fermentation step: the temperature of controlling in bank is spent 30～35, and maintain 30-60 days, when plastics film to the air-proof condition of bank constant and in heap temperature start to lower, and occur that ammoniacal liquor distinguishes the flavor of and/or wine flavour, in the adularescent mycelia, finish fermenting process in heap simultaneously;

9): the bank after fermentation is spread out, dried to moisture≤30%.

Described step 6) carry out the length of the bank of windrow in: wide: height is 5 meters: 5 meters: 2 meters.

Described step 8) the leavening temperature scope in is 15～70 degrees centigrade, when the temperature of bank, higher than 65 degrees centigrade the time, need to carry out the turning step.

Described step 8) pH value in will be controlled between 6.5～8.5.

Wood raw material in of the present invention, as the content of bark and leaf etc. reaches 70～90%, greatly reduced usage quantitys of other assorted material, has less, the easy to make advantage of the auxiliary material of use.

Embodiment 1: 29 parts of 70 parts, the mallee bark after pulverizing and the mixture of leaf, 1 part of parent of fermentation, the animal excrement after pulverizing, and after evenly mixing, add water to moisture 60%, fermented.

Embodiment 2: 18 parts of 80 parts, the mallee bark after pulverizing and the mixture of leaf, 2 parts of parents of fermentation, the animal excrement after pulverizing, and after evenly mixing, add water to moisture 60%, fermented.

Embodiment 3: 7 parts of 90 parts, the mallee bark after pulverizing and the mixture of leaf, 3 parts of parents of fermentation, the animal excrement after pulverizing, and after evenly mixing, add water to moisture 65%, fermented.

The organic chemical fertilizer that present method makes can directly be used in agriculture production, also can be for making organic chemical fertilizer or mixed organic manure etc.Of many uses.
