It mixes.The wastes of crops is sugarcane end pin leaf；Bacillus thuringiensis microbial inoculum is commercially available, wherein living bacteria count
For 20,000,000,000/gram.The fermentation assistant is EM bacteria agent, and the dosage of EM bacteria agent is that 200 grams are added in every cubic metre of fermentation raw material.
It is grown cane using the method for embodiment 4, continuous plantation 3 years is not necessarily to additional irrigation water, need to only carry out disease prevention work
Make, hectare average productivity is 112500 kilograms；And identical area, the simple method for applying compound fertilizer grow cane, hectare produces
Amount is only 75000 kilograms.
It should be noted that the difference of the method for the simple application compound fertilizer addressed in above-described embodiment and embodiment method
It is not apply biogas residue, does not irrigate biogas slurry-water mixed fertilizer and biogas slurry-aqueous mixtures, but with 75 kilograms of per hectare of compound fertilizer
Substitution, compound fertilizer's substitution of biogas residue half quality, irrigation quantity and irrigates biogas slurry-water mixed fertilizer and biogas slurry-aqueous mixtures dosage
It is identical；In fact, this method, compared with embodiment 1-4, the dosage of compound fertilizer and the dosage of water have increase.
Experiment discovery by contrast: (1) increase the ratio of biogas slurry, such as by the weight of biogas slurry and water in biogas slurry-water mixed fertilizer
Part ratio is changed to 1:1；Biogas slurry in biogas slurry-aqueous mixtures and the weight ratio of water are changed to 2:1；These change to sugarcane yield
Influence it is little, average product is still 1166250/ hectare, is not that the more high then yield of Rate of Organic Fertilizer is higher, it is contemplated that natural pond
The cost of manufacture of liquid is high, therefore should reduce the dosage of biogas slurry.
(2) if substituting biogas residue with the compound fertilizer of half quality before cane planting, remaining operation is same as Example 1, then
The sugarcane yield underproduction 10%, but the biogas residue for making biogas slurry nowhere utilizes；If with etc. quality compound fertilizer remaining operation and implement
Example 1 is identical, then the sugarcane yield underproduction 6%, but the increased costs of compound fertilizer, and the biogas residue for making biogas slurry nowhere utilizes.
(3) biogas slurry, biogas residue, compound fertilizer, water dosage it is same as Example 1 in the case where, difference is to apply biogas slurry
With on ridge, water is irrigated in plantation row, and separate administration, the results show that the yield of sugarcane is only 101250 kilograms/public affairs
Just, the reason of consideration is that nutrient excessive concentration in biogas slurry, mobility in the soil is slow, is administered alone and is unfavorable for sugarcane
It absorbs,
To sum up, fertilizer formula of the invention prepares phase using sugarcane end pin leaf (or rice straw), pig manure as primary raw material
The biogas slurry and biogas residue answered carry out the water-fertilizer integral plantation of sugarcane, can save liquid manure resource, improve sugarcane yield.By
The different growing stages of sugarcane apply different amounts of liquid manure, and realization is precisely controlled liquid manure dosage, and different times are to sugarcane production
Required liquid manure has supplement, promotes the growth of sugarcane.Under normal conditions, agriculturist only applies biogas slurry as organic fertilizer, remains
Remaining biogas residue is unfavorable for recycling for resource for discarding after fermenting or handling again, and the embodiment of the present invention is by production
Biogas slurry and biogas residue use simultaneously, reduce the accumulation of waste, can also handle stalk, sugarcane end pin leaf etc. in agricultural production immediately
Waste realizes recycling for resource.
