Description
Technical field
The present invention relates to agriculture and forestry crop, the irrigation of plant, fertilising, dispenser fields, more particularly to one kind having piston pump
Water-fertilizer integral irrigate, fertilization system.
Background technology
Liquid manure, water medicine or water-fertilizer-pesticide integrated technique are a new agricultural technologies actively pushing forward of country, it have it is quantitative,
The features such as metering, accurate, slight irrigation, the on-demand use of fertilizer, liquid is realized, both ensure that crop different times can normally give birth to
It is long, and saved fertilizer, reduce environmental pollution, just because of it is many a little, recent years, the Integration of Water into Fertilizer existed
It is widelyd popularize in agricultural production.
Fertilising device for administration of drugs and micro-irrigation emitter are the integrated critical equipment of slight irrigation water-fertilizer-pesticide, the class for the device for administration of drugs that applies fertilizer
Type mainly have gravity self-pressing type, Development of Venturi Fertilizer Applicator, differential pressure fertilization pot, ratio fertilizing pump, pump suction-type, pump it is pouring-in and it is complete from
Dynamic intelligent irrigation fertilizing equipment, micro-irrigation emitter mainly have drip irrigation zone (pipe), mini sprinkler, fine-spraying belt, spring douche etc., irrigate
Principle be irrigation volume, irrigation frequency and time will according to it is medicinal/fertilizer with plant water-requiring property, growing stage, weather, soil item
, in due course, in right amount depending on part etc., Rational Irrigation, fertilising, dispenser, and according to different terrain geomorphologic characteristics and crop characteristic, screening
Applicable fertilising dispenser equipment, and distributed rationally, it is the basis that water-fertilizer-pesticide integration is smoothly implemented.
By taking slight irrigation water-fertilizer-pesticide integration critical equipment in orchard is screened and is distributed rationally as an example：
Screening, assembling and the optimization of fertilising device for administration of drugs
According to Hills orographic condition, the planting type of crop, different stages of growth to the demand of water-fertilizer-pesticide, analysis
The pattern and scale of irrigation system and the indexs such as the water-power performance parameter of fertilizer apparatus and economy, filter out applicable fertilising
Device for administration of drugs；According to crop water-fertilizer-pesticide handling characteristics and irrigation system parameter, with system energy consumption, cost and pour water, dispenser of applying fertilizer
Uniformity is target, establishes the optimized Selection and Optimal Configuration Method of fertilising device for administration of drugs, proposes the operation of fertilising device for administration of drugs
Regulation.
At this stage, for different regions or different crop features, various fertilising device for administration of drugs (such as Development of Venturi Fertilizer Applicator,
Differential pressure fertilization pot, ratio fertilizing pump, pump suction-type, fine-spraying belt etc.) be obtained for different applications and achieve it is good irrigate,
Fertilization effect.
However we have found that water-fertilizer integral system is in use for existing positive displacement pump (such as piston pump, diaphragm pump)
Since liquid or solution have certain chemical corrosivity, existing liquid manure, water medicine or water-fertilizer-pesticide integral system still have
The case where fertilizer applicator/piston pump is corroded will result in piston pump performance and decline, cannot accurately count once piston pump is corroded
Amount is even damaged.Although also someone wants to solve the problems, such as this, it is designed, improves from pump configuration, material, seal aspect,
It never solves the above problems well, pump usage time is grown, and fertilizer applicator/piston pump can also have the feelings being centainly corroded
Condition causes to pump performance decline, is unable to accurate measurement, even damages, in this regard, we have proposed a kind of new solutions, to row
Industry progress has certain help.
