Description
Technical field
The invention belongs to technical field of fertilizers, be specifically related to a kind of medicine fertilizer slow-release preparation and preparation method thereof and application process.
Background technology
The essential macroelement of growth and development of plants comprises carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K) etc.Wherein carbon, hydrogen, oxygen are natural nutrition element, mainly come from sky G&W.Nitrogen element is the moiety of many kinds of substance in plant materials, for example, range protein, chlorophyll etc., many kinds of substance pathways metabolism in its involved in plant body, is one of requisite element of plant.Phosphorus is the participant of every metabolic process in plant materials, transport, sucrose, starch and the polysaccharide compound of for example carbohydrate synthetic; Phosphorus is also improved plant drought, the resistance such as cold-resistant and adapts to the ability of external environmental condition.Potassium element can improve plant to the absorbing of nitrogen, and strengthens the resistance of plant, as drought resisting, disease-resistant etc.The nitrogen phosphorus potassium of as fertilizer sources three elements is nutrients that plant first should ample supply.If want to bring into play the effect of other nutrient, also need on the basis of nitrogen phosphorus potassium abundance, just likely realize.Plant is large to the demand of nitrogen phosphorus potassium, and soil often can not independently meet the needs of crop, so, apply nitrogen phosphorus potassium by the artificial external world and seem particularly important.
Crop pests is also one of important factor affecting crop yield and quality.For crop pests, the main chemical insecticide that uses is prevented and treated at present.Wherein Diacloden (thiamethoxam) is the anabasine insecticide of a kind of efficient, low toxicity, wide spectrum, its mechanism of action is mainly that selectivity suppresses insect central nervous system nicotinic acid nAChR ligands, and then the normal conduction of blocking-up insect central nervous system, death while causing insect to occur paralysis machine.Diacloden not only have tag, stomach toxicity and systemic activity, and there is better security, wider insecticidal spectrum and the feature such as speed of action is fast, the lasting period is long, be the better kind that replaces those are high to mammalian toxicity, have residual and environmental problem organic phosphates, amino formate and organochlorine insecticides.Diacloden is to Coleoptera, Diptera, lepidopteran, especially homoptera pest has high reactivity, can effectively prevent and treat the insects such as various aphids, leafhopper, plant hopper, aleyrodid, chafer larva, colorado potato bug, nematode, ground beetle, leaf miner and the broad variety insect to chemical pesticide generation resistance.Diacloden both can be used for cauline leaf, seed treatment, also can be used for soil treatment.
Corps diseases is an other factor that affects crop yield and quality.Corps diseases is mainly the disease being caused by pathogenic micro-organism infection crops, and for example, fungi, bacterium, virus, parasitics pathogenic micro-organism infect caused disease.At present, mainly prevent and treat by chemical fungistat.Wherein Silthiopham, chemical name N-allyl group 4,5-dimethyl-2-trimethyl silicane thiophene-3-carboxylic acid amides.Research shows that Silthiopham is inhibitor of energy, has good prolection, and the longevity of residure is long.Suitable crop and the security wheat to crop, to crop, Mammals, environmental safety.Silthiopham can strongly inhibited take-all for wheat seed dressing generation.
In traditional proportion of crop planting technology, Crops in Applying Fertilizer, dispenser are separately carried out, and cause peasant's labour intensity large, work often.And fertilizing management and dispenser prevention and control do not have specific aim yet, easily cause blindly fertilising, medication, cause fertilising imbalance, insect pest, diseases control not good.So, be also necessary Crops in Applying Fertilizer, insect-pest, disease prevention to be studied, to improve the service efficiency of agricultural chemicals and fertilizer, realize in effectively pest control, disease, supplement on the basis of crop nutrient elements, reduce labour intensity.
Summary of the invention
In view of this, goal of the invention of the present invention is to provide a kind of medicine fertilizer slow-release preparation, its preparation method and application process.Medicine fertilizer slow-release preparation provided by the invention has the three efficacy of desinsection, antibacterial and fertilizer, can prevent and treat crop pest, disease and the required nutritive ingredient of supplementary plant growth simultaneously, and drug effect and fertilizer efficiency lasting period extend, utilization ratio and the result of use of agricultural chemicals and fertilizer are improved, strengthen drug effect, fertilizer efficiency, and significantly reduced peasant's labour intensity.
