Description
Technical field:
The invention belongs to technical field of fertilizers, be specifically related to a kind of balanced type fertile containing humic acids akaline liquid and
Preparation method.
Background technology:
The growth of crop be unable to do without Organic carbon and nitrogen, phosphorus, the big nutrient of potassium four.Having of a large amount of soil of China
Machine matter content is on the low side, soil acidification, hardens serious, a large amount of use traditional fertilizer and is excessively used pesticide, making
Becoming biological activity of soil low, serious restriction agricultural production is to the ecological agriculture, green agriculture, Organic Farming.
The livestock-raising industry of China is very big at the proportion of agricultural production, breeding disparate development, a large amount of feces of livestock and poultry
Failing efficient resource utilization is put into environment, causes a large amount of water body and soil pollution, the money of agricultural wastes
Source recycles the most less, and annual substantial amounts of burning causes the pollution of air.Utilize feces of livestock and poultry and agriculture
Biotechnology fermentation is passed through, it is possible to obtain biogas slurry, biogas residue and compost aerobic fermentation sepage as garbage, these
It it is all the organic fertilizer resource of high-quality.
The water quality characteristic of biogas slurry and compost aerobic fermentation sepage makes Crop be exceedingly fast, and existing quick-acting is held concurrently again
Tool slow.Often executing biogas slurry, plant growth is healthy and strong, and vane thickness and fruit weight dramatically increase, and quality shows
Write and improve, can improve about yield 15-35%, soluble sugar mean height 36%；To crop nutritional deficiency disease, as little
Leaf disease has specially good effect；Improve Physiological changes simultaneously, improve freezing tolerance, can be rated as " king in fertilizer ".Biogas slurry institute
Containing the butanoic acid in organic acid and the gibberellins in auxin, heteroauxing and vitamin B12 etc.,
Cell membrane and the vivo protein matter of unicellular pathogenic bacteria can be destroyed, effectively control the breeding of harmful levels of pathogens；Biogas slurry
In ammonia, ammonium salt and antibiotic, can suppress and close the respiratory system of the pest and disease damages such as red spider, thus reach
Anthelmintic, parasite killing, the effect of sterilization.Fruit tree putrefaction disease, ring spot, dry rot, root rot, speckle are fallen
Leaf disease, mould cardiopathia, brown spot, powdery mildew, diplostomiasis, red spot disease；Pear scab；Grapevine anthracnose,
White rot, gray mold, downy mildew, anthrax；Fructus Pruni pseudocerasi blade face shothole disease, leaf spot, bleeding disease；Fruit tree
Nearly all fungus, the bacteriosises such as vegetable and land for growing field crops epidemic disease in seedling stage, banded sclerotial blight all have obvious control action.
To aphid, red spider, white Aranea, maggot, heart-eating worm ovum, Pieris rapae, beet armyworm, bollworm etc. several
All pest and disease damages all have notable preventive effect, use the crop of biogas slurry can reduce prevention and control of plant diseases, pest control number of times throughout the year, and
Pollution-free, without residual hazard, without Drug resistance, be otherwise known as " biological pesticide ".
Potassium fulvate is that a kind of pure natural mineral active potassium element is fertile, and the content of organic matter is more than 50%, includes micro-
The multiple nutritional components such as secondary element, rare earth element, plant growth regulator, viral inhibitors, have improvement
Soil aggregate, chesson, improves the water conservation fertilizer-preserving ability of soil.Regulation pH value, reduces in soil
The content of heavy metal, reduces salt ion to seed and the harm of seedling.There is fixed nitrogen, phosphorus decomposing, activation potassium merit
Energy.The particularly potentiation to potash fertilizer is particularly evident, plays extraneous root strong sprout, anti-continuous cropping, disease-resistant, Crop Improvement
The effect of quality.Can the adhesive force of fortification of plants root system and rapid absorption ability, make the more vigorous leaf of crop plant type
Color is more dark green, and lodging tolerance is higher, makes soil activating, reduces continuous cropping disease.
