Abstract

The invention discloses a water and fertilizer integration technology mode suitable for north tea gardens, and belongs to the technical field of tea tree cultivation. The mode includes construction of a fertilizer formulation pool, an installation method of a venturi and a water meter, main water pipe laying, branch pipe micro-spraying tape placement, high-pressure water spraying and low-pressure fertilization technical measures and the like. The mode is characterized by comprising the steps: dissolving a water soluble fertilizer in the fertilizer formulation pool, and placing a micro-spraying tape between two rows of tea trees; through controlling a switch of the venturi, carrying out spray irrigation water application in the high water pressure and the high flow quantity, and carrying out drip irrigation fertilization in the low water pressure and the low flow quantity; after fertilization is completed, carrying out spray irrigation again; and changing a fertilization mode of 'one-time base fertilizer application and three-time top application' into a mode of 'one-time base fertilizer application and six-time top application'. Compared with the prior art, spray irrigation is carried out in the high water pressure and the high flow quantity, so that requirements of tea garden irrigation are met, and a tea garden 'microclimate' is regulated and controlled; drip irrigation of the water soluble fertilizer is carried out in the low water pressure and the low flow quantity, so that the fertilizer is allowed to be farthest distributed around tea tree rhizospheres, and fertilizer absorption of the tea trees is facilitated; and at the same time, a past tea garden three-time top application is changed into multi-time top application, continuous fertilizer requirements of the tea trees are met, and the purpose of saving water and the fertilizer is achieved.

Description

One is suitable for northern tea place the Integration of Water into Fertilizer pattern
Technical field
The invention belongs to tree plant cultivation technical field, relate to one and be suitable for northern tea place the Integration of Water into Fertilizer pattern.
Technical background
Water relation, to the metabolic intensity of tea tree and direction, also affects various organic formation and accumulation in tealeaves, also very big on the impact of yield and quality, and northern tea place air is dry, cannot meet the demand of tea tree to moisture by rainfall and general irrigation., mainly there are 5 problems in multiple spray, drip irrigation equipment that existing part tea place adopts: 1, spray used, drip irrigation equipment cost are often too high, are not suitable at tea place spread; 2, some sprinkling irrigation equipments are placed on large tea interline, affect other farming activities of tea place; 3, shower head used very easily stops up and damages; 4, difficult and fertilising combination, fertilization effect is bad; 5, the lack of homogeneity of water spray, can not water moisture to be filled in around Rhizosphere Soils in Tea Garden to greatest extent.
The impact of fertilising on tea yield quality occupy the first in cultivation management.Current northern tea place adopts " base three chases after " fertilizer application mode more, needs repeatedly ditching-fertilizing.Mainly there is following shortcoming in this pattern: 1, easily tea root is caused to damage; 2, concentrate fertilising, cause the waste of fertilizer; 3, fertilizer efficiency is short, can not continue to provide nutrient to tea tree; 4, need to use a large amount of labours to carry out ditching-fertilizing.
Summary of the invention
The object of this invention is to provide one and be suitable for northern tea place the Integration of Water into Fertilizer pattern, reach sprinkling irrigation by the hydraulic pressure size of venturi switch control branch road water pipe and water, fertigation.
The technical issues that need to address of the present invention are: overcome the deficiency in technical background, provide one to be suitable for northern tea place the Integration of Water into Fertilizer pattern, improve tea place microclimate, increase tea tree air humidity, increase diffuse reflection, supply with in time tea tree fertilizer, be beneficial to the g and D of tea tree.
Technical scheme of the present invention is: comprise the construction in fertilizer formula pond, and the installation way of venturi and water meter, water main is laid and the placement of branch road water pipe fine-spraying belt, sprays water with high pressure and the content such as low pressure fertilizer practice measure.It is characterized in that: the size in fertilizer formula pond need be determined by tea place size and irrigated area, generally long 0.5m left and right, wide 0.5m left and right and dark 1m left and right, available cement brick is built into, and does water leakage processing; Side is installed into water pipe, for preparing water soluble fertilizer solution.Fertilizer formula pond the inside must be that water soluble fertilizer mixes with water, by fertilzer sucking pipe to tea tree fertilizer; Venturi and water meter lay down location are built into cement brick, its long 1m, wide 0.5m and dark 0.5m, and the inside water meter is near branch road fine-spraying belt, and fertilzer sucking pipe is connected with venturi; Water main need be embedded in end 50cm place, ground, and branch road water pipe must use fine-spraying belt, and places it in the middle of two row tea trees, and micro-spraying hole upward; Control branch road water pipe hydraulic pressure and flow by the switch of controlling venturi, in the time of high hydraulic pressure, high flow capacity, sprayed in whole tea place; Spray after certain water yield, then in the time of low hydraulic pressure, low discharge to Rhizosphere Soils in Tea Garden fertigation; After fertilising finishes, again adjust water main hydraulic pressure and flow, tea tree is watered a certain amount of.Watering the water yield determines according to the tea tree age of tree, soil water content and water soluble fertilizer kind.Change " base three chases after " fertilizer application mode into " base six chases after ", in growth of tea plant season, between March to August, monthly topdress once, decide according to growth of tea plant situation and target output the consumption that topdresses.
Mechanism of the present invention is: utilize this device to improve hydraulic pressure and carry out micro-spray, first can significantly improve efficiency of water application, then can improve northern tea place air humidity, increase diffused light, improve the amino acid content of holding tender property and green tea of tea shoot, then improve the quality of green tea.Water soluble fertilizer is dissolved in to the inside, fertilizer formula pond, carry out fertigation by controlling venturi reduction hydraulic pressure, a part of water yield of spraying again after fertilising, can arrive around soil lower floor tea root fertilizer, liquid manure acting in conjunction, can better be absorbed by tea tree fertilizer.Change " base three chases after " fertilizer application mode into " base six chases after ", according to growth of tea plant situation and target output, topdress several times, can continue to provide nutrient to tea tree, thereby improve to greatest extent tea yield and quality.
Effect of the present invention is: 1, adopt the cost of this invention technology lower by 30% than general spray drip irrigation equipment; 2, with fine-spraying belt sprinkling irrigation, make the atomizing effect in tea place good, significantly improve the air humidity in tea place.3,, compared with the method for application of general spray drip irrigation equipment, the fine-spraying belt modes of emplacement that this invention adopts can not affect other farming activities in tea place.4, the present invention reduces labor cost 30% than ditching-fertilizing, reduces tea place liquid manure cost more than 40%, and high grade tea output promotes more than 35% than tea place of the same age, and the output value increases 50%-60%.
