Abstract
The present invention relates to a nutrient solution containing glycine organic nitrogen fertilizer instead of nitrate nitrogen fertilizer for soiless culture of fruits and vegetables or foliage spray, and uses the glycine chelate as microfertilizer portion instead of inorganic salt and EDTA salt to produce nuisanceless fruits to be no pollution and vegetables.
Description
The soilless culture, particularly water planting that the present invention relates to not contain nitrate and contain glycine and glycine chelate thing grows fruit and the nutritive mediums of vegetables, also can be used as fertilizer for spraying on leaf surface simultaneously and is used for various forms of cultivations.Can produce the fruits and vegetables that meets national pollution-free food quality standard with the present invention.
At present, the soilless culture nutrient fluid that China is existing, all be to be main composition by nitrate, phosphoric acid salt, vitriol and EDTA inner complex, various concrete prescriptions all are prescription and the principles based on people such as public technology fritz Sa Qisi in 1860 and Ke Nuopu, adjust slightly according to different sorts crop and the specific requirement of each vegetative period to fertilizer, these soilless culture nutrient fluids all have good production performance.
But, rise the idea of production and consumption pollution-free food (China claims green food) from the seventies developed country after, various countries comprise that China makes laws in succession and formulates pollution-free food national standard and production, examination rules.
Nitrate is one of oxious component that is subjected to the strict restriction of pollution-free food, because it is the final root that produces strong carcinogens N-nitrosodimethylamine, nitrate in the fruits and vegetables derives from uses inorganic nitrogenous fertilizer, and especially nitrate fertilizer, so pollution-free food producting rule forbids to use nitrate fertilizer.
In soilless culture is produced, because fruits and vegetables have strict demand to the pH value of nutritive medium, dissolved salt concentration etc., and fruits and vegetables cause inventing over more than hundred year from cultivation technique without soil, so far still with the principal mode of nitrate nitric nitrogen as nitrogenous fertilizer to ammonia-state nitrogen hyperabsorption reason such as can poison.
Soilless culture is owing to be that the greenhouse sealing is produced, can both effectively control for all other the nuisanceless indexs except that nitrate content, and can break away from the restriction of soil, weather condition, the batch production of realization anniversary is produced, its output and production efficiency are the several times of traditional agriculture, beyond doubt one of Agricultural Development direction.But, because this unique and crucial obstacle of nitric nitrogen, stopped soilless culture particularly water planting lead to the road of producing nuisanceless fruits and vegetables.
Purpose of the present invention overcomes this major obstacle of nitric nitrogen exactly, realize soilless culture particularly water planting be not less than to contain in production performance and produce high-quality nuisanceless fruits and vegetables under the Nitrate Nutrition liquid prerequisite.
Because every performance index of fertilizer for spraying on leaf surface, than soilless culture nutrient fluid require loose manyly, therefore, use as foliage fertilizer when no matter the present invention can have soil or soilless culture to produce nuisanceless fruits and vegetables equally.
The present invention glycine (english abbreviation Gly, molecular formula NH
2CH
2COOH) this organic nitrogen replaces the nitrate nitric nitrogen, and as the component of nitrogenous fertilizer in the nutritive medium, its consumption is not to be reduced to principle with nitrogen content in the nutrient solution prescription that contains nitrate to convert, and adjusts consumption according to concrete crop absorption rate again.
Research of plant physiology and fertilizer science and evidence, plant root and leaf portion can directly absorb glycine as absorbing nitrate radical, and supply is equivalence fully for nitrogenous fertilizer in this replacement, and vegetation growth state is identical.But therefore eliminated Nitrate Accumulation in the plant materials, reached the purpose of producing nuisanceless fruits and vegetables.
Another technological improvement of the present invention is to make sequestrant and micro-metals calcium, magnesium, iron, manganese, zinc, the synthetic inner complex of copper or complex compound with glycine, does little fertile part with these complex compounds.Substitute inorganic salt and edta salt, its consumption also is to replace with mole such as various metal inorganic salts, this replacement has brought two advantages: the one, because " chelate effect " improved the chemical stability and the solubleness of each metal ion species, and the ferrous ion of oxidation precipitation very easily particularly.The glycine chelate thing has played the provide protection same with the EDTA inner complex.The 2nd, because " bio-imitability " of glycine chelate thing is that glycine chelate thing and plant mesophytization material are (as " enzyme ",) chemical structure is approximate, it is close to secrete the absorption mechanism that absorbs together again behind the sequestrant chelated metal ions when also absorbing the nutrition metallic element with plant root earlier, this " anti-natural disposition " is very beneficial for the utilization after trace elements absorbed and the absorption, thereby the effect that improves fertilizer efficiency is arranged.
Another advantage that the present invention embodies simultaneously, " cushioning effect " that is nutritive medium is obvious, because the both sexes disassociation property that main composition glycine of the present invention has, the variation of liquid PH value there is certain opposing elasticity, and keeps the stable significant of pH value plant-growth.
Nitrogenous fertilizer and glycine are done sequestrant and to have the resiliency three inseparable because glycine is done, killing three birds with one stone, and therefore, the present invention no longer divides an application the latter two.
In order to reduce the nutritive medium cost, can use small part acid amides attitude and ammoniacal nitrogen fertilizer among the present invention, replace glycine as urea, ammonium sulfate, bicarbonate of ammonia, but its total consumption is too much unsuitable, otherwise production performance can descend, optimum range is 0%-50%.
