Background technology
The fruit of Vitis Vitaceae (Vitaceae) plant grape (Vitis vinifera L.).Being defoliation liana, is one of world " four big fruit trees ".Because grape is of many uses, economic worth is high.In recent years China's wine-growing development rapidly.According to statistics, Chinese grape in 2007 area world rankings the 5th of receiving, gross output rank the 3rd.But single rate has been compared tangible gap, only the rank world the 20th with advanced international standard.The mode of production of the most of viny region of China is tradition relatively also, carries that hand waters, the mode of furrow ditch flood irrigation is of common occurrence on the shoulder, and this becomes restriction China grape per unit area yield and continues the important restraining factors that increase.Simultaneously also serious waste the valuable water resources and the manure resources of China.
In recent years, how more reasonably to use effective resource, produce more agricultural-food of fine more and become the key subjects of pendulum in face of compatriots, and the integrated drip irrigation of liquid manure is as the technology of cultivating the another great revolution of sciemtifec and technical sphere after mulch film, booth, progressively accepted, and produced huge economic benefit and social benefit by vast wine-growing person.
The integrated drip irrigation technique of liquid manure is a technology of water, fertile synchronization control, and crop absorbs nutrient when absorbing moisture.Be called " water and fertilizer coupling ", " with the water fertilising ", " fertigation " etc. again.It utilizes the drip irrigation facility nutrient that crop is required, moisture minimum concentration ground to supply with, and fertile, water soaks into ground 25cm～45cm equably, makes the crop root prosperity.The integrated drip irrigation of liquid manure remarkable benefit in viticulture has following reason: 1. drip irrigation saving of labor water saving cuts down the consumption of energy.Drip irrigation can fix a point the soil of water supply to the crop root distribution range is reduced water evaporates, and water utilization rate can reach more than 95%.2. the minimizing nutrient loss improves utilization rate of fertilizer.Most of fertilizer are taken to deep soil by water in the traditional irrigation mode, lose with current.Utilize fertigation can control rich water and all be positioned at root zone, effectively prevented nutrient loss, also reduced the pollution of chemical fertilizer simultaneously farming district water system.3. the reduction field humidity reduces disease and takes place." high humidity " problem of air is the main factor that causes facility cultivation disease pilosity in the facility cultivation.Adopt drip irrigation soil table wetted area little, soil evaporativeness is few, thereby reduces field humidity effectively.4. promotion high grade and yield of crops.Drip irrigation can timely and appropriate discovery, evenly keep the skin wet and nutrient for crop exactly, makes crop be in best moisture, nutrient status all the time, thereby improves plant to the nutrient absorbing amount, promotes plant health growth, raising agricultural product quality and output.
The integrated drip irrigation technique of liquid manure has so many advantage to make this technology become a standard technique of China's wine-growing.But the integrated drip irrigation technique of liquid manure is an integrated technology, has gathered all multidisciplinary correlation techniques such as irrigation engineering, soil science, Plant Nutrition, fertilizer science.And the development of Plant Nutrition and fertilizer science is slower, becomes one of topmost bottleneck of the faster development of the restriction integrated drip irrigation technique of China's liquid manure.The most critical problem is exactly that China does not also have a kind of grape growth that promptly is suitable for to grow the fertilizer that is fit to drip irrigation system again at present at present.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can satisfy the grape fruit expanding stage, can prevent high concentration drip irrigation fertilizer exclusively used in fruit enlargement period of grapes of using because of mineral element the fertilizer waste that relatively too much causes and preparation method thereof again nutrient demand.
The present invention utilizes low technical grade of foreign matter content or agricultural level straight fertilizer as raw material, for grape make a kind of can blocking dropping head or strainer is produced the high-content grape drip irrigation system compound fertilizer special of excessive pressure.The present invention has simultaneously added chelated microelements simultaneously according to the demand of grape fruit expanding stage to nutritive element, thereby further promotes special-purpose fertilizer efficiency fruit and enlarge its adaptive faculty.Give full play to the effect that the drip irrigation system joint is fertile, efficient, improve crop yield, quality by using this special-purpose fertilizer to reach; And the whole potential of release drip irrigation technique.
Macroelement nitrogen, phosphorus, potassium are mainly provided by saltpetre, potassium primary phosphate, urea in this grape fruit expanding stage drip irrigation special fertilizer; Moderate-element is provided by magnesium sulfate heptahydrate; Trace element is provided by EDTA chelated iron, EDTA chelated copper, EDTA Chelated Manganese, Sodium orthomolybdate, EDTA chelating zinc, boric acid.
