Description
Technical field
The present invention relates to no earth culture technical field of cultivation, in particular to a kind of zinc salt containing single amino acid, manganese salt chelate
Fruits and vegetables mill water culture nutrient solution.
Background technique
Modern hydroponics technology replaces farmland planting to be applied to the production of fruits and vegetables, provides various safety, Gao Pin for the mankind
The fruits and vegetables food of matter, has become the mark of modern agriculture.Although China carries out hydroponics, research is later, according to statistics,
Only 7 hectares from 1985 of China's water planting area, 315 hectares in 2005 are developed to, have turned within 20 years 45 times, development is also quickly
's.Hydroponics area with China is constantly expanding, and cultivation technique is also being continuously improved.The domestic China national that obtains is known at present
Know the approval of property right office various plant hydroponics nutrient solution prescription patents reached it is hundreds of, indicate the hydroponics technology in China into
A booming phase is entered.
The growths of fruit trees and vegetables be unable to do without the microelements such as nitrogen, phosphorus, potassium, calcium, magnesium nutrition element and zinc, iron, manganese, therefore water
Cultivating nutrient solution is formulated mainly using the salt of these elements as raw material through dissolution.Overtesting is not proved inorganic microelement
Salt is very low by the absorption rate of plant, therefore has invented and substituted inorganic microelement salt using EDTA complexing trace element salt, with
Improve the plant absorption utilization rate of microelement.But it is changed to EDTA complex compound (EDTA: ethylenediamine tetra-acetic acid), although can improve
Plant is to the absorption rate of complex compound microelement, but EDTA is the substance not being absorbed by plants, but also is that one kind is difficult to
The weak acid being biodegradable can also dissolve deposited toxic heavy metal if being discharged into water body, bring harm to environment.Water planting battalion
Nutrient solution is generally in such a way that supplement consumes elemental composition, with the service life for the liquid that has additional nutrients, when the micro member of EDTA complexing
After element is consumed, remaining EDTA increases accumulation because supplement consumes element, may finally influence the using effect of nutrient solution, shadow
Ring service life.

Number is made into value=1.00 EC, the solution (hereinafter referred to as " comparison liquid ") of pH value=6.5.In two adjacent cultivation casees respectively into
Row control cultivation.Test period 28 days.
When experimental period starts, nursery first week, value=1.00 EC, pH value=6.5 are used using " experimental liquid ".Nursery second
Week, Miao Changzhi 10cm, additional " new liquid " make " experimental liquid " concentration to value=1.20 EC, and pH value is not higher than 7.0.It is all to third, when
The root of spinach has been grown to compared with the maturity period, and additional " new liquid " makes " experimental liquid " concentration to value=1.50 EC, adjust pH value 6.5~
6.8." experimental liquid " concentration is just no longer promoted with latter week.Use " comparison liquid " of the control group of " old liquid " additional with the same period
Mode is cultivated.To when harvesting in 28 days, EC value is reduced to 0.80 or so, pH 7.0.If Fig. 1 a is to be planted using " comparison liquid "
Spinach growth figure, Fig. 1 b be using " experimental liquid " plantation spinach growth figure.Comparison diagram 1a, Fig. 1 b, it can be seen that Fig. 1 b
The plant type of spinach is more greatly in plant type ratio Fig. 1 a of middle spinach.
" new liquid " and " old liquid " test result: the spinach for using " new liquid " to cultivate, up to 28cm, weight reaches every plant height degree
60g.24 plants of whole group behind removal root and planting medium, weigh about 1.5 Kg altogether.And the about 26cm of " old liquid " is used, weight
55g.24 plants of whole group behind removal root and planting medium, weigh about 1.2Kg altogether.Use the leaf of " new liquid " cultivation spinach in deep
Green, growth stage also shorten 3~5 days than control group.Fig. 3 a is using the plant type figure of the spinach of " comparison liquid " plantation, and Fig. 3 b is
Using the plant type figure of the spinach of " experimental liquid " plantation.Comparison diagram 3a, Fig. 3 b, it can be seen that in Fig. 3 b in plant type ratio Fig. 3 a of spinach
The plant type of spinach is more greatly.
Test proves " new liquid " of the present invention, adds single amino acid zinc salt and manganese salt, and more conducively water planting fruits and vegetables are made
