Description
Technical field
The present invention relates to soil improvement fermenting fertilizer field, more particularly to a kind of Reclaimed Land green fertilizer application method.
Background technology
The per capita area of cultivated farmland of China is had a large population and a few land, soil pressure is very huge less than four one-tenth of world average level.I
Government of state has carried out house site and has reclaimed project, to rural area configure it is improper, utilize the unreasonable house site disperse, leave unused, discarded
Implement to arrange and reclaim, becomes arable land resource.However house site Reclaimed Soil is because brick stone is more, soil nutrient status
It is poor, cause soil original function and characteristic to be lost, causes crop yield and quality low.However after current house site is reclaimed
Fermenting fertilizer applies excessive organic materials and inorganic fertilizer more, and amount of application seriously exceeds soil bearing capacity, exists and cause soil
And the risk of environmental pollution；Excessively there is also heavy metals for application or even portion of techniques addition flyash, mine tailings etc. for feces of livestock and poultry
The substance that equal potential pollutions threaten；Using the measures such as the miscellaneous smoked soil for waiting weeds and leaf of dry beans are burned, soil is only carried out merely and is supported
Point fertilizing, and do not consider soil nutrient growth, safety of soil environment, operating cost and crop short-term yield etc. and ask
Topic.
Meanwhile China is the first big country of global Edible Fungi, annual generated culture medium of edible fungus waste material (bacteria residue)
Reach 8.0 × 107T becomes the third-largest agricultural wastes in addition to stalk, feces of livestock and poultry.Current annual bacteria residue efficiently uses
The 50% of lazy weight total amount, most of bacteria residues are incinerated, abandon or heap is abandoned, and not only cause a large amount of organic resources and land resource
Waste, returns surrounding enviroment and brings certain ecological pollution risk.Some researches show that bacteria residues to contain a certain amount of N P and K etc.
Nutrient can increase soil fertility after, improve water flowing situation of breathing freely, and promote crop yield.Meanwhile bacteria residue is remained
Content of beary metal it is lower than organic materials such as animal feces of livestock and poultry, caused by risk of environmental pollution it is small.However it is current, it is based on bacteria residue
Still lack using house site Reclaimed Land green fermenting fertilizer.
Invention content
In view of this, the present invention provides a kind of Reclaimed Land green fertilizer application methods.The Reclaimed Land green fertilizer application method
