Summary of the invention:
The invention provides a kind of preparation method of special selenium-rich foliage fertilizer, its objective is for there is harm to crop and environment in the foliage fertilizer that overcomes rich selenium, reduce its toxicity, and can increase aspect its utilization ratio.
For achieving the above object, the present invention is by the following technical solutions:
A kind of preparation method of special selenium-rich foliage fertilizer is characterized in that: the method is mainly carried out through following steps:
(1), in the growth cycle of Herba Astragali Melilotoidis (Herba Astragali Sinici) plant, spray by stages sodium selenite solution, the concentration of sodium selenite solution is 120 * 10
﹣ 6～240 * 10
﹣ 6G/cm,
(2), pulverize, squeeze the juice, filter the Herba Astragali Melilotoidis (Herba Astragali Sinici) plant of Enriching Selenium is whole, obtain the Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid that is rich in organoselenium of biological attitude;
(3), Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid is mixed with white carbon black, blending ratio is Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid: white carbon black=3:2～5:2, mixed solution gets product through fully stirring, filtering.
In step (1), respectively spray sodium selenite solution three times at the early growth period of Herba Astragali Melilotoidis (Herba Astragali Sinici) plant, growth mid-term and initial bloom stage respectively, the concentration of the sodium selenite solution that sprays at early growth period is 120 * 10
﹣ 6G/cm is 180 * 10 in the concentration of sodium selenite solution of growth midterm spray
﹣ 6G/cm, the concentration of the sodium selenite solution that sprays at initial bloom stage is 240 * 10
﹣ 6G/cm;
White carbon black described in the step (3) is that white carbon black with precipitator method preparations is for selecting object.
The invention has the beneficial effects as follows:
By respectively spraying sodium selenite solution three times at selenium enriching plant Herba Astragali Melilotoidis (Herba Astragali Sinici) early growth period, mid-term, initial bloom stage, the rich selenium Herba Astragali Melilotoidis (Herba Astragali Sinici) plant integral body that gathers is pulverized, squeezed the juice, filters, obtain the Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid that is rich in organoselenium of biological attitude.Because the toxicity of the organoselenium of biological attitude is lowered far away, therefore crop and environment are safe from harm; Simultaneously, because the high-hydroscopicity of white carbon black and dispersed the utilization discharge the selenium element lentamente on the blade face, improved the utilization ratio of selenium-enriched foliage fertilizer.
Embodiment:
For reducing the toxicity of inorganic Sodium Selenite, should find a kind of plant, it can absorb the selenium element well, and inorganic selenium is converted to the organoselenium of biological attitude, thereby reduces its toxicity.Herba Astragali Melilotoidis (Herba Astragali Sinici) (formal name used at school: be the plant of pulse family Astragalus Astragalus sinicus), be distributed widely in the area of 400 meters to 3,000 meters of height above sea level, be grown in small stream limit, hillside and moist place more, also often have in the farmland of rural households.Study discovery through us, it can absorb the selenium element well, and the plant that can become rich selenium collection is cultivated, and also because its growth cycle is short, and widely distributed, we just expect with it making selenium-enriched foliage fertilizer as raw material.
The Herba Astragali Melilotoidis (Herba Astragali Sinici) of early growth period still can not the too high sodium selenite solution of spraying concentration, therefore, we respectively spray sodium selenite solution three times at the early growth period of Herba Astragali Melilotoidis (Herba Astragali Sinici) plant, growth mid-term and initial bloom stage respectively, and the concentration of the sodium selenite solution that sprays at early growth period is 120 * 10
﹣ 6G/cm is 180 * 10 in the concentration of sodium selenite solution of growth midterm spray
﹣ 6G/cm, the concentration of the sodium selenite solution that sprays at initial bloom stage is 240 * 10
﹣ 6G/cm sprays respectively.Cut off the Herba Astragali Melilotoidis (Herba Astragali Sinici) plant of whole strain after the blossom fall and clean, pulverize, squeeze the juice, after testing, 128～249 milligrams of every milliliter Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid Nitrogen elements, 120～224 milligrams of phosphoric, 128～249 milligrams of potassium elements, 0.005～6 milligram of selenium element.
For improving the utilization ratio of selenium element, the mode that we adopt Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid to be combined with white carbon black.Preparing white carbon black by precipitation method refers to sulfuric acid, hydrochloric acid, CO
2With water glass be the silicon-dioxide that basic raw material is produced, the precipitator method are again the water glass acidization, adopt water glass solution and acid-respons, through precipitation, filter, washing, dry and calcine and obtain white carbon black.Reaction formula is:
Na
2SiO
3+ 2H+-〉 white carbon black+2Na++H
20
Most domestic manufacturing enterprise adopts the precipitator method.We also are the white carbon black products of buying from the market, and we do not relate to the white carbon black of additive method preparation.
We mix Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid with white carbon black, blending ratio is Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid: white carbon black=3:2～5:2, mixed solution gets product through fully stirring, filtering.
The rich selenium Herba Astragali Melilotoidis (Herba Astragali Sinici) of organic grass juice factor liquid is adsorbed, because white carbon black has very large inside and outside specific surface area, slowly release again after absorbing in a large number the rich selenium Herba Astragali Melilotoidis (Herba Astragali Sinici) of organic grass juice factor liquid, long for the plant leaf surface soak time like this, effective, the toxicity of selenium is burnt to corps leaf surface greatly reduce.
The application's fertilizer for spraying on leaf surface has carried out bio-transformation with this extremely cheap height selenium enriching plant of Herba Astragali Melilotoidis (Herba Astragali Sinici) to inorganic selenium, with the Herba Astragali Melilotoidis (Herba Astragali Sinici) grass juice factor liquid of a large amount of Enriching Selenium elements of extracting as the foliage-spray raw material.This preparation method has overcome rich selenium fertilizer for spraying on leaf surface in the past excessive concentration has been burnt the blade face of causing during to directly the spraying of plant, the farm crop page with the sodium selenite solution of inorganic form that (the inorganic selenium solution such as bud seedling vegetable sprays, it is the sodium selenite solution of the extremely low concentration tender shoots of also can burning, and many farm crop for the selenium solution that reaches the requirement of being rich in high selenium content and just should spray respective concentration seedling period to reach purpose and the effect of rich selenium accumulation), cross when concentration and not reach again so that crop is rich in the purpose of high selenium content when low.
The direct use inorganic selenium salt foliage-spray technology that present technique is different from the past, rely on and rich selenium carrier Herba Astragali Melilotoidis (Herba Astragali Sinici) juice cheapness, enormous amount, preparation method are simple, avoided the technology such as dependence complexing and the organoselenium that produces is with high costs, selenium content is low, water soluble characteristic is poor, the shortcoming that can not generally use.Rich selenium Herba Astragali Melilotoidis (Herba Astragali Sinici) juice is that Sodium Selenite is through the plant rich in selenium juice of a bio-transformation, its toxicity is well below with isocyatic sodium selenite aqueous solution, to most plants and its each vegetative period the blade face directly spray, can not produce the blade face and burn.Its large number of biological attitude organoselenium that is rich in has higher bioavailability than inorganic sodium selenite solution simultaneously.In technology was in the past used, rich selenium Herba Astragali Melilotoidis (Herba Astragali Sinici) Ceng Zuowei paddy rice " green manuring fertilizer " material was carried out the root fertilising to crop.Farm crop but more and cash crop also are not suitable for together planting with Herba Astragali Melilotoidis (Herba Astragali Sinici), and the rich selenium Herba Astragali Melilotoidis (Herba Astragali Sinici) juice that present technique is squeezed can be sent forth in the overwhelming majority and needs on the crop of selenium element, and the last dried dregs of Herba Astragali Melilotoidis (Herba Astragali Sinici) of squeeze juice equally can be used as Se-enriched bio fertilizer crop is carried out the root fertilising simultaneously.
Experiment detects:
Present techniques has been carried out 50 mu enforcement in Kaiyuan City three home townshiies, is mainly used in spraying of paddy rice.The selenium-rich rice of results send Shenyang Inst. of Applied Ecology, Chinese Academy of Sciences's agricultural product security and environmental quality inspection center to detect then, and detected result is for being rich in the selenium element, and the per kilogram rice contains 0.69 milligram of selenium element.
