Description
Technical field
The invention belongs to fertilizer field.Particularly, the present invention relates to a kind of foliage fertilizer and preparation method thereof.
Background technology
Bamboo vinegar liquid is in the process of making charcoal with bamboo wood, collects the gas that bamboo wood produces in pyrolytic decomposition, and this gas is cooled off the liquid substance that obtains at normal temperatures.Bamboo vinegar liquid contains nearly 300 kinds of natural polymer organic cpds, comprises the alkaline components of organic acid, alcohols, ketone, aldehydes, ester class and trace etc.
Bamboo vinegar liquid can be improved the soil, and bamboo vinegar liquid is sprayed at the damping-off that can prevent seed in the soil, also can be used as the sterilizing agent of soil.Use the effective inhibition of bamboo vinegar fluid power in the soil and hinder the breeding of the mikrobe of plant-growth; And can kill insects such as root nodule nematode; Can effectively improve the microbe groups of soil; Promote organism to decompose and utilize, thereby crumb structure, air permeability, the water-permeable of soil are improved, improve fertilizer utilization ratio.Bamboo vinegar liquid or plant-growth regulator, bamboo vinegar liquid can promote agronomic crop seed germination, takes root, grow, and can also promote the growth of plants such as vegetables, fruit tree, flowers, paddy rice, lawn.In addition, bamboo vinegar liquid can also be made fertilizer, suppresses the growth of weeds, reduces pesticide dosage, as the repellent of insect pest etc.Bamboo vinegar liquid has good control effect to plant pest, unites use with agricultural chemicals and also has good synergism, and reduction pesticide dosage, minimizing pesticide residue are had good result.
Chitin extensively be present in the crusts of crustaceans such as shrimp, crab and molluscan organs such as the cell walls of mushrooms such as mushroom and cuttlefish in; Be that 2-ethanamide-2-deoxy-D-glucose is through β-1; 4 glycosides chains connect the straight-chain polysaccharide that forms, and are a kind of new type natural macromolecular materials that emerges in recent years.Be called chitosan behind the chitin deacetylate, this is the most important and most widely used verivate of chitin, and it is nonpoisonous and tasteless, heat-resisting, corrosion-resistant, biodegradable, and unique physiological property causes people's very big concern.At present, its exploitation, research and utilization in various fields such as medicine industry, foodstuffs industry, water treatment, daily cosmetic, agricultural, weaving, printing and dyeing, papermaking, mould material, catalysis and analytical chemistry is just being received the attention of many countries.Chitosan contains free hydroxyl group and amino isopolarity group, has very strong water-absorbent and water-retentivity, can be used for the mechanism of dry seed germination or as seed treatment agent, makes seed be embedded in the infringement that prevents mould in the soil in the paint film; Its hydrolysate also can be used for the foliage-spray of crop, has plant growth regulation.The main effect of chitin on agricultural is propagation soil profitable strain, suppresses harmful bacterium; Inducing plant is opened autoimmune response, improves farm crop and vegetable disease-resistant property, minimizing or without the use of agricultural chemicals; Promote plant-growth, improve farm crop and vegetable crop.
Foliage fertilizer is meant that through crop leaf be the general designation that crop provides the fertilizer of nutritive substance, and it can replenish the deficiency of root fertilising, has rapid extra-nutrition, gives full play to fertilizer efficiency, economical and alleviate the pollution characteristics to soil.But in view of the textural difference of blade face and root, how to solve the fully effective absorption nutritive ingredient in blade face is the important topic of industry research always.
