The quantities of nitrogen, phosphorus, potassium and other elements received by the cucumber are in positive correlation with the yield of the cucumber; the cucumber dedicated nutrient solution is rich in N, P, K, Ca and other elements, and can provide nitrogen, phosphorus, potassium and calcium required for growth of the cucumber; according to nutrition demand quantities at seedling stage, flowering stage and fruiting stage, the cucumber dedicated nutrient solution is fed into a drip irrigation system by means of the water and fertilizer integration technology so as to be dripped in several times, so that the nutrients required for growth of the cucumber is ensured, the yield and the commodity rate of the cucumber are improved, and the output value is improved.
Description
Technical field
The present invention relates to the nutritional solution of a kind of biogas slurry digestion preparation, be specifically related to cucumber dedicated nutrient solution and the using method thereof of the preparation of a kind of biogas slurry digestion.
Background technology
Fructus Cucumidis sativi originates in the Tropical rain forest area of southern foot, the Himalayas, is initially wild, becomes crisp sweet good to eat Fructus Cucumidis sativi by cultivated since long, improvement.The edible part of Fructus Cucumidis sativi is young tender ovary, and fruit color is glossy dark green or emerald green.Fresh and tender Fructus Cucumidis sativi poppyhead is barbed, tempting food.The crisp sweet succulence of sarcocarp, has delicate fragrance taste.The most generally cultivate, transplant after nursery in the early spring, or spring, summer are directly sowed, it is possible to greenhouse production.Fructus Cucumidis sativi to the reception amount of large quantities of elements such as nitrogen, phosphorus, potassium with yield in the most relevant, the Fructus Cucumidis sativi often producing 1000Kg needs 2.6 kilograms of nitrogen, phosphorous oxide 0.9 kilogram, potassium oxide 3.9 kilograms, calcium oxide 3.9 kilograms.
Biogas slurry is the widely known a kind of quick-acting of people and the long-lasting bio-organic fertilizer having both, and is the optimal fertilizer producing Organic food.Containing abundant nitrogen, phosphorus, potassium, each amino acid, vitamin, protein, gibberellins, auxin, saccharide, nucleic acid and antibiotic etc. in biogas slurry, and butanoic acid, heteroauxing, vitamin B12 isoreactivity resisting substance.Therefore have and promote plant growth and control the dual function that disease occurs.The water quality characteristic of biogas slurry makes Crop be exceedingly fast, existing quick-acting, has again slow concurrently.
Owing to the reception amount of cucumber production and large quantities of elements such as nitrogen, phosphorus, potassium is in the most relevant, and biogas slurry does not contain only all kinds of aminoacid, vitamin, protein, gibberellins, auxin, saccharide, nucleic acid and antibiotic etc., and butanoic acid, heteroauxing, vitamin B12 isoreactivity resisting substance, and the nitrogen having required for cucumber growth containing abundant, phosphorus, potassium.Based on this, develop a by the nutritional labeling needed for biogas slurry digestion, interpolation cucumber growth, make the research purpose that the cucumber nutrient solution being specifically designed for growing is the present invention.
Summary of the invention
The invention reside in the cucumber dedicated nutrient solution that the preparation of a kind of biogas slurry digestion is provided, based on biogas slurry, the nutritional labeling configuration required for raw material science interpolation cucumber growth forms, not only production cost is low, the feature of environmental protection is high, and the nutrition needed for ensure that cucumber production, improve yield and the commodity rate of Fructus Cucumidis sativi, improve the output value.
The concrete technical scheme of the present invention is as follows:
A kind of cucumber dedicated nutrient solution of biogas slurry digestion preparation, the part by weight of its composition and preparation is as follows: biogas slurry: potassium nitrate: calcium nitrate: Diammonium phosphate (DAP)=45～60:0.8～1.2:1.4～2:0.05～0.15, and described biogas slurry takes from the biogas slurry of becoming thoroughly decomposed discharged in methane-generating pit after normal temperature anaerobic fermentation produces biogas through 20 mesh above filter screen filtration gained；Described extraction compound method is:
Biogas slurry after filtering is placed in and extracts pond accordingly, and is added into potassium nitrate, calcium nitrate and Diammonium phosphate (DAP) in described biogas slurry in proportion；
Under normal pressure and temperature, described room temperature refers to 10～35 DEG C, after soaking 1.5～2.5 hours, carry out stirring for the first time, backward after soaking 1～1.5 hour, being again stirred, the stirrer paddle diameter of described stirring is slightly less than described extraction pond diameter, the rotating speed of described stirring: 30～80R/min, each mixing time: 8-12min；
After extraction is dissolved 4～8 hours, obtain described cucumber dedicated nutrient solution through 25 mesh above filter screen filtration preparations.
The application process of the cucumber dedicated nutrient solution of a kind of biogas slurry digestion preparation, described cucumber dedicated nutrient solution, according to cucumber at seedling stage, the nutritional requirement of phase of yielding positive results, uses the Integration of Water into Fertilizer to enter drip irrigation system by several times and carries out fertigation；Carry out as follows:
(1) to flower early stage after slow Seedling, the every L of described cucumber dedicated nutrient solution adds clear water 55～65L drip irrigation and uses 1 time；
(2) fruiting period 1st month, described cucumber dedicated nutrient solution every L addition clear water 60～70L carries out drip irrigation and uses, and the time interval that drip irrigation is used is every 5～6 days 1 time；
(3) fruiting period the 2nd, 3 months, the every L of described cucumber dedicated nutrient solution adds clear water 55～65L to carry out drip irrigation and uses, and the time interval that drip irrigation is used is every 5～6 days 1 time；
(4) fruiting period 4th month, described cucumber dedicated nutrient solution every L addition clear water 70～80L carries out drip irrigation and uses, and the time interval that drip irrigation is used is every 6～8 days 1 time.
Advantages of the present invention and effect:
This cucumber dedicated nutrient solution, form with the nutritional labeling configuration that biogas slurry is added required for cucumber growth for digestion agent through science, described cucumber dedicated nutrient solution adds employing the Integration of Water into Fertilizer entrance drip irrigation system after clear water is diluted and carries out fertigation, cucumber dedicated nutrient solution after dilution is applied to the root of crop, not only production cost is low, and the feature of environmental protection is high, and the nutrition needed for ensure that cucumber production, improve yield and the commodity rate of Fructus Cucumidis sativi, improve the output value；The pollution problem simultaneously solving arbitrarily discharging of biogas slurry and cause.
