Description
Technical field
The invention belongs to fertilizer field, particularly, relate to a kind of fertilizer that comprises APG, humic acids and tea saponin, particularly relate to the fertilizer of a kind of promotes growth, raising the output and the heavy metal contamination of reduction crop.
Background technology
Soil is the mankind's physical environment of depending on for existence and the valuable source of agriculture prodn, and along with developing rapidly of industrial or agricultural and mining industry, the heavy metal pollution problem of soil is more and more outstanding.
The mechanism that heavy metal element absorbs and transports in making object is considered to each element closely related at intravital mechanism of absorption of plant and Biochemical processes.Zinc, copper are the essential trace elements of plant, but poisonous when excessive, plant absorbing zinc is main with metabolism; Cadmium, lead are the nonessential elements of plant, and cadmium is the poisonous element that accumulates easily, and it has passive absorption and metabolism to absorb, and lead element is passive absorption.
Water paddy soil of China and rice heavy metal pollution problem are quite serious.It is reported that China receives nearly 2,000 ten thousand hm of cultivated area of heavy metal contaminations such as Cd, As, Cr, Pb at present
2, account for 1/5 of total area under cultivation, nearly 1.33 ten thousand hm of cultivated area that polluted by Cd
2, relate to 11 and economize 25 areas, cause more than 1,000 ten thousand tons of annual grain drop in production, nearly more than 1,200 ten thousand tons in contaminated grain adds up to financial loss to reach 20,000,000,000 yuan at least.According to Ministry of Agriculture's rice and quality of item supervision and inspection center thereof the security of national market rice is inspected by random samples the result, the exceeding standard rate of cadmium (Cd) surpasses 10%, and therefore, the pollution that how to reduce heavy metal in the soil Rice System becomes the scientific research emphasis day by day.
The method of the reduction crop heavy metal contamination of taking at present is a lot; Mainly be to reduce to the discharging three wastes chemical industry tailing that tills the land; Or,, be exactly to improve crop varieties in addition like soil moved in to improve the original method, leaching method etc. through physical method; Be exactly the chemical improvement agent that adopts soil in addition, but present chemical amelioration agent effect is all undesirable.
The present invention provides a kind of and can promote plant growth, raising the output simultaneously and reduce the pollution of heavy metal in soil to crop for solving the problems of the technologies described above, and reduces the composite fertilizer compositions of heavy-metal residual in the crop.
Summary of the invention
For solving the problems of the technologies described above; The invention provides a kind of composite fertilizer compositions that is used to promote plant growth, raising the output and can reduces crop heavy metal contamination simultaneously; Particularly; The invention provides a kind of composite fertilizer compositions that comprises inorganic fertilizer mixture and fertilizer mixture, the weight ratio of inorganic fertilizer mixture and fertilizer mixture is 80-95: 5-20 in the said composition, and wherein the inorganic fertilizer mixture is made up of the component of following weight percent content:
Sal epsom 2-10%
Zinc sulfate 1-5%
Potassium primary phosphate 10-20%
Vitriolate of tartar 5-10%
Lime 55-65%
The fertilizer mixture is made up of the component of following weight percent content:
Humic acid substance 85-95%
APG 1-7%
Chitin 1-6%
Tea saponin 1-5%.
Preferably, in the above-mentioned compsn, the inorganic fertilizer mixture is made up of the component of following weight percent content:
Sal epsom 10%
Zinc sulfate 5%
Potassium primary phosphate 10%
Vitriolate of tartar 10%
Lime 65%.
Preferably, in the above-mentioned compsn, the fertilizer mixture is made up of the component of following weight percent content:
Humic acid substance 85%
APG 7%
Chitin 3%
Tea saponin 5%.
In the above-mentioned compsn, preferred, lime is unslaked lime, and it mainly acts on is to improve pH in soil, reduces the content that soil pH can reduce solvable heavy metal in the soil, reaches crop and can absorb the heavy metal content reduction, and lime can also provide calcium constituent simultaneously.Other organic mixing through in humic acid substance and the fertilizer mixture can strengthen the long-acting fertility of fertilizer mixture to crop, and promote the absorption of crop to useful nutritive substance, reduce the absorption of crop to heavy metal.
In the above-mentioned compsn, humic acid substance (HA) is ulmic acid, Ulmic acids and/or xanthohumic acid, and is especially preferred, and humic acid substance is an xanthohumic acid.
The present invention also provides the preparation method of above-mentioned composite fertilizer compositions, and this method comprises the steps:
1) preparation inorganic fertilizer mixture: take by weighing raw material and mix according to each set of dispense ratio of said inorganic fertilizer mixture;
2) preparation fertilizer mixture: take by weighing raw material and mix according to each set of dispense ratio of said fertilizer mixture;
3) with step 1) and step 2) preparation inorganic fertilizer mixture, fertilizer mixture mix according to said proportioning, prepare composite fertilizer compositions.
The present invention also provides the another kind of preparation method of above-mentioned composite fertilizer compositions, and this method comprises the steps:
Take by weighing raw material and mix according to each set of dispense ratio in said inorganic fertilizer mixture and the fertilizer mixture and promptly get composite fertilizer compositions.
The purposes that the present invention also provides above-mentioned composite fertilizer compositions to be used to promote plant growth, raising the output and to reduce crop heavy metal contamination is characterized in that using as base fertilizer or using as topdressing in the vegetative period of crop in the seeding crops phase.
In the such use, heavy metal is preferably cadmium, copper or lead.Crop is preferably paddy rice, wheat, sugarcane or corn, is preferably paddy rice especially.
Beneficial effect:
Inorganic fertilizer mixture in the above-mentioned composite fertilizer compositions of the present invention provides the nutritive element of crop; Like required nutritive substances of plant such as nitrogen phosphorus magnesium, potassium and calciums; But the single nutritive substance that provides can not impel crop absorption of nutrients matter longer, also needs fertilizer to promote the long-acting absorption of crop to inorganic fertilizer.And the fertilizer mixture provides plant nutrient substance on the one hand, promotes the absorption of inorganic fertilizer simultaneously, and fertilizer can adsorb the heavy metal in the soil simultaneously, reduces the absorption of plant to heavy metal.And the inorganic fertilizer mixture can also reduce pH in soil, reduces absorbable heavy metal content in the soil.The effect that the mixing of various ingredients is played in the fertilizer mixture is that one-component is irreplaceable, and this combination is played and cooperatively interacted, the effect of forward influence each other, makes and in reducing crop heavy metal contamination, plays important effect.
Compsn of the present invention shows through secular field experiment, not only can improve the upgrowth situation of crop, and can increase crop yield, reduces the heavy metal contamination in the crop.
