A kind of preparation method of the novel all organic cultivation medium containing soft weedtree
technical field:
The present invention relates to a kind of preparation method of the novel all organic cultivation medium containing soft weedtree for bare place vegetables and Vegetable, belong to field of agricultural production technologies.
background technology:
China's exploitation is used for the cultivation matrix of organic vegetable and is mostly organo-mineral complexing matrix, or for formula is more complicated, take the peat composed of rotten mosses as the composite interstitial substance of main component, use cost is higher.In conventional cultivation matrix large mainly with the peat composed of rotten mosses as main raw material, and the peat composed of rotten mosses mainly originates in China northeast, and by region restriction and be Nonrenewable resources, overexploitation will inevitably cause resource exhaustion, the destruction eubiosis.For above problem, find a kind of novel matrix and replace Nonrenewable resources to be very necessary.At present, the novel cultivation matrix that China is being studied, mainly using the waste of agriculture production as object filtering matrix, its advantage is that cost is low, materials synthesis localization, is organic culture substrate that is economical, renewable, environment-friendly type.
Soft weedtree is the timber of Midst density, and kind is more, and resource distribution is looser, has nanmu, linden etc., and feature is that material is comparatively light, and opposed configuration loosens.Soft weedtree keeps good fibrousness, has good water-retentivity after carrying out rubbing silk processing.
Coconut palm chaff is cocoanut husk fiber dust, is the organic medium of a kind of pure natural under coming off from cocoanut husk fiber process.Powdered carbon (semiactive charcoal) is by Organic farming wastes such as crop materials, pyroprocessing is carried out when anoxic, oil is wherein gentle burn after remaining material, it is the product that Mierocrystalline cellulose and hemicellulose slightly carbonize, organic content is high, and Ph value is lower, because most of agricultural wastes and bacterium slag are all in alkalescence, so the interpolation of powdered carbon alleviates this situation largely, organic substrate is made to reach neutral.Powdered carbon has improvement soil property, promotes the formation of soil agreegate, has the characteristics such as regulating and controlling effect to Ecological Distribution of Soil Microorganisms.
summary of the invention:
The object of the present invention is to provide a kind of preparation method of the novel all organic cultivation medium containing soft weedtree, improve the environment of soil, for cultivated plant provides abundant, comprehensive nutritive element, make full use of waste in agriculture production as base starting material simultaneously, environmental protection more, more economically, thus reduce the production cost of matrix.
For achieving the above object, technical scheme of the present invention:
Containing a novel all organic cultivation medium for soft weedtree, be prepared from by the raw material of following parts by volume: coconut palm chaff 20 ~ 30 parts, powdered carbon 5 ~ 10 parts, soft weedtree 20 ~ 30 parts, the peat composed of rotten mosses 10 ~ 20 parts.
The above-mentioned novel all organic cultivation medium containing soft weedtree, preferably, coconut palm chaff 20 parts, powdered carbon 5 parts, soft weedtree 30 parts, the peat composed of rotten mosses 10 parts.
A kind of preparation method of the above-mentioned novel all organic cultivation medium containing soft weedtree:
(1) adopt feces of livestock and poultry, stalk or sucrose to regulate and the carbon-nitrogen ratio of soft weedtree is adjusted to 25 ~ 30:1, add aerobic fermentation bacterium; Bar buttress formula or raft fermentation, become evenly in the fluffy dry and comfortable material of brown and carbon-nitrogen ratio is down to 15 ~ 17:1 to fermented product; Obtain soft weedtree fermented product;
(2) spray Antagonistic Fungi after being mixed with soft weedtree fermented product by the coconut palm chaff of being down to less than 0.1 through the desalinization of soil by flooding or leaching, EC value, bar buttress formula or raft ageing 20 to 40 days, to water content 20-30%, obtain biological base;
(3) biological base and powdered carbon, the peat composed of rotten mosses are mixed in proportion, obtain novel all organic cultivation medium.
Between the fermentation of step (1) and (2) or aging period, within 5 to 7 days, stir once, the sudden and violent gas of ventilation oxygenation is no less than 3 times.
Described zymophyte is the one in VT-aerobic fermentation bacterium such as aerobic fermentation bacterium, EM zymophyte, and its consumption is the 0.05-0.2% of soft weedtree quality.
Described Antagonistic Fungi is blight Antagonistic Fungi, downy mildew of cucurbits Antagonistic Fungi or plant rhizosphere growth-promoting bacterium (PGPR), and its consumption is the 0.1-0.5% of coconut palm chaff and the mixed quality of material of soft weedtree fermented product.
The invention has the beneficial effects as follows:
1. the cultivation matrix water-retentivity of the present invention's preparation is strong, and probiotics is abundant, miscellaneous bacteria content is few, and various organic substance is composite, can provide abundant, comprehensive nutritive element for plant-growth, and the plant growing way of cultivating is good, be of high nutritive value.
2. base starting material of the present invention is based on organic solid castoff material, not only solves the process problem of organic solid castoff material, environmental protection more, more economically, thus reduces the production cost of matrix.
3. do not use chemical fertilizer, the equal degradable of various organic substance; Not only can not cause soil compaction problem but also can edatope be improved, increasing soil fertility.
4. use soft weedtree and powdered carbon as base starting material, not only can improve edatope, reduce the production cost of matrix, and to exploitation organic culture substrate that is economical, renewable, environment-friendly type, there is profound significance.
embodiment:
Embodiment 1-10
Raw material: be down to coconut palm chaff, powdered carbon, soft weedtree, the peat composed of rotten mosses of 0.09 through the desalinization of soil by flooding or leaching, EC value.
Its parts by volume is as table 1:
Table 1
Operation steps:
(1) get the soft weedtree mixed in the ratio of table 1, adjustment carbon-nitrogen rate is to 25 ~ 30:1; Add VT-aerobic fermentation bacterium (mass ratio of VT-aerobic fermentation bacterium and soft weedtree is 1:1000), after mixing, raft fermentation or bar pile up neatly formula technique 20 ~ 40 days, 5 to 7 days periods turned over the once sudden and violent gas of ventilation oxygenation and are no less than 3 times, became evenly in the fluffy dry and comfortable material of brown and carbon-nitrogen ratio is down to 15 ~ 17:1 to fermented product; Obtain soft weedtree fermented product;
(2) the coconut palm Kang being down to 0.09 through the desalinization of soil by flooding or leaching, EC value is mixed with soft weedtree fermented product, then spray plant rhizosphere growth-promoting bacterium (PGPR) according to the mass ratio of 1000:3, bar buttress formula or raft ageing 20 to 40 days, period can stir 1 to 2 time, be dried to water content 20%, obtain biological base;
(3) biological base, powdered carbon, the peat composed of rotten mosses are mixed in the ratio of table 1, obtain novel all organic cultivation medium.
Prepare raw material according to the ratio of table 1, operate according to above-mentioned steps, embodiment 1-10 has prepared matrix 1, matrix 2, matrix 3, matrix 4, matrix 5, matrix 6, matrix 7, matrix 8, matrix 9, matrix 10 respectively.
The novel all organic cultivation medium containing soft weedtree of embodiment 1-10 and conventional cultivation matrix are (containing the peat composed of rotten mosses and vermiculite, mass ratio is 2:1) every physico-chemical parameter and the growth indexes of the watermelon seedlings of cultivating (except matrix is different, other cultivation conditions are identical) contrast, as table 2:
Table 2
The data of table 2 show, the organic content of novel all organic cultivation medium of the present invention, saturation moisture capacity (water retention property), probiotics content are all higher than commodity cultivation matrix.And the growth indexes of the watermelon seedlings using novel all organic cultivation medium of the present invention to cultivate is close with the growth indexes of the watermelon using conventional cultivation matrix, and surviving rate is higher.
