土壤污染治理须看“全科大夫”

发布时间:2015-7-17 11:27:24 浏览次数:1061

近几年,土壤污染已成为社会反响度很大的环境问题,特别是国内耕地重金属污染更是成为稻农发展生产的一块心病。听行内朋友讲,国内有家公司独辟蹊径走出一条从土壤调理入手综合修复耕地质量的新路,让受镉污染困扰的稻农找到了科学施救方法。前不久,记者在江苏苏州脉慧特集团总部见到了集团董事长夏金华先生。

5年前,夏金华在调研中得知国内耕地重金属和药残超标影响了农产品的品质,也影响了消费者的健康。他想“自己的生物医药是治疗病人,能不能通过改善修复被污染的土壤,生产出优质农产品,让消费者不生病或少生病,把住病从口入关。”于是,夏金华成立了脉慧特科技集团旗下骨干企业——中科慧盛生物科技有限公司,开始从事土壤与植物品质提升的事业,“中科慧盛”立志要做国内首家土壤修复的“全科大夫”。

1土壤重金属污染的主要成因

夏金华告诉记者,去年环保部和国土部公布数据显示:国土壤总的超标率为16.1%,其中轻微、轻度、中度和重度污染点位比例分别为11.2%、2.3%、1.5%和1.1%。耕地土壤环境质量也同样堪忧,有的地区问题更加突出。污染类型以无机型为主,有机型次之,复合型污染比重较小,无机污染物超标点位数占全部超标点位的82.8%。无机污染物:镉、汞、砷、铜、铅、铬6种无机污染物点位超标率分别为7.0%、1.6%、2.7%、

2.1%、1.5%、1.1%。

耕地重金属污染形成,一般主要有如下原因,一是受当地工矿业,特别是化工企业排污污染;二是被污染的灌溉水污染;再就是土壤原有本底值遍高,这种情况主要发生山区省份,一般认为有山就有矿,有矿多有金属,在土壤自然形成过程中土壤重金属含量本身就偏高。但有些重金属在土壤中呈固化和钝化的状态,一般不太被植物吸收。只有给它一定诱因,如含镉土壤过度酸化后,金属离子被激活就会被植物吸收,造成农作物重金属超标。

2土壤污染修复要适合国情

目前,土壤污染修复在国际上通行做法是化学固化、土壤淋洗、电动修复、植物修复等方法。夏金华讲,这些方法“中科慧盛公司”都可以做,但有的方法只适用于工业污染和住宅建设用地处理,它成本太高不适合耕地处理,况且修复后的土壤重金属去掉了,有益营养成份也同时去掉了,变成了“死土”,因此显然不能用于耕地修复。

当下,全世界在耕地重金属污染修复方面,几乎没有什么可供借鉴的先例,日本虽有几十年治理经验,但治理稻田镉污染一亩地需投入的成本合人民币1~2万元,这显然不适合中国国情。况且不同国家土壤状态不一样,即使是同一个国家不同地区的土壤状况也不一样,很难用一个模式套用照搬。目前,各国耕地修复普遍采用的是固化和钝化的方法。国内各地在生产中创造出不同做法,如湖南的“石灰中和法”、“深翻土壤中和法”及“控氧化法”等等,这些都能起到一定作用,但并不是十分科学的方法,就像“专科诊治”就医,难以从根本上综合解决问题。

“中科慧盛”拥有自主知识产权独立开发和生产的重金属污染土壤修复材料和土壤调理剂(中慧一号),倡导从土壤污染治理与修复和土壤与植物品质提升这点同时入手,综合修复调理土壤。试验表明,轻度与中度重金属污染治理,平均每亩地投入费用200~1000元,施用修复剂300~600公斤,作物可有效减少重金属吸收30%~60%,达到国家规定标准。去年,慧盛一号在湖南两块镉污染地块分别划区分块进行了对比试验。试验表明,通过水稻单季(80多天),作物镉含量指标明显降低。今年,已在南方多地进行大面积的重金属镉污染耕地修复应用。

3土壤污染需要综合治理

夏金华告诉记者,“中科慧盛”积极倡导的是一种“全科大夫”的观点,做“稻法自然”的慧盛模式,就是要尊重自然,恢复自然,不是就治理而治理,而是将镉包括其他重金属治理放在土壤修复的大背景下来做。慧盛一号实际上包含有修复剂、肥料、调理剂和其他基质,表明它综合性修复的特色。它作用机理是针对高强度利用下土壤退化与植物健康退化的内在原因,研制集调节土壤pH、钝化重金属有效性、抑制土传连作病害为一体的来调理土壤健康,通过快速修复退化土壤,降低土壤中重金属对农产品的传递和富集。同时,满足植物和土壤生物营养需求的节本、提质、增产、增效的绿色施肥技术体系,平衡、提升作物营养结构,增强有益微量元素的吸收。充分激发土壤土著生物的作用,提高土壤生态系统的健康和免疫能力,构建基于“治末病”理念的土壤病害防治新原理及其技术,通过营养生态调控方式调节作物的健康与土壤生态系统健康状况。

夏金华讲,“稻法自然”慧盛模式的最大好处,就是既把病看好了,同时还让土壤健康了,使土壤中该提高的营养成份提高,把该去除的去除。对土壤是多种污染同时并存的,就不能单一化配方,要系统考虑问题,要用“复方制剂”的理念。土壤数据每年也是动态的,各地土壤存在差异,因此土壤修复也要像中医看病,因人施方,要常复查,不断对修复剂配方进行调整。镉污染治理最终操作要田间种植管理者辅助来完成,因此操作应像就医服药,第一要配最适合的药方,第二要用最简单服药方式,第三效果一定要明显,这才便于农民操作和接受。

前年,公司在苏州市的吴江市震泽镇众安桥村周生湖旁流转了近千亩水稻田。通过近三年对土壤调理修复,记者看到,现在轮作的小麦长势相当不错,随手拔了棵即将成熟的小麦,只见根系十分发达,土黑油油的,健康又肥沃。夏董事长说:“这就是调理修复剂起得作用,去年修复了一年多的地种的水稻亩均收获1100多斤。那稻米香味别提多足了,营养也丰富,尤其适合孕妇和儿童,一斤可卖到30元。”

“通过我们实践,土壤污染治理和修复关键的是要综合考虑,修复后土壤不能再形成二次污染。我们作物秸秆全部提供给周边畜牧企业和卖掉,或自己环保处理。综合修复后让土壤始终呈现出健康状态,地力肥了,营养充足了,作物病虫害自然也少了。因此,化肥减施了,农药也少撒了,这既符合‘双减’的零增长,同时农作物品质也显著提升了。我们认为,土壤和人一样,如果病了,看全科大夫可能会好得快一点和彻底一点。”夏金华说。


In recent years, soil pollution has become a social echo a lot of environmental problems, especially the domestic arable land, heavy metal pollution is a trial to be rice farmers to develop production. Listen to industry friends, domestic companies going out of one, from the perspective of the soil conditioning comprehensive repair of cultivated land quality of new road, let polluted by cadmium in rice farmers find the rescue method of science. Recently, the reporter is in jiangsu suzhou pulse see hui group headquarters group chairman Mr Xia Jinhua.

Five years ago, Xia Jinhua in research in domestic arable land, heavy metal exceeds bid and medicine residual affected the quality of agricultural products, also affect the health of consumers. He wanted to "their own biological medicine is treating patients, can by improving the repair of contaminated soil, and produce high quality agricultural products, do not let the consumer get sick or less sick, treating the illness." So, Xia Jinhua formed pulse technology corp., the backbone enterprises of hui, CST hui sheng biotechnology co., LTD., began a career in the soil and plant quality improvement, aspired to be a first "zhongke hui sheng" soil restoration "all-around doctor".

1 the main cause of soil heavy metal pollution

Xia Jinhua told reporters, according to the data published last year, the ministry and the ministry: the total soil which was 16.1%, the mild, mild, moderate and severe pollution point ratio of 11.2%, 2.3%, 1.5% and 2.3% respectively. Farmland soil environment quality is equally worrying, some regional issues become more prominent. Pollution type is given priority to with no models, a machine times and the compound pollution is small, the inorganic pollutants exceeds bid point number accounts for 82.8% of the total standard points. Inorganic pollutants, cadmium, mercury, arsenic, copper, lead, chromium 6 kinds of inorganic pollutants points which were 7.0%, 1.6%, 2.7%,

2.1%, 1.5%, 1.1%.

Arable land, heavy metal pollution formation, general mainly has the following reasons, one is influenced by the local GongKuangYe, especially chemical enterprise sewage pollution; The second is the contaminated irrigation water pollution; And soil background values over high, this kind of situation mainly mountainous province, it is generally believed, the mountain is the mine ore more metal, soil heavy metal content in the process of natural soil itself on the high side. But some of the heavy metals in the soil was in curing and passivation of the state, is generally not too absorbed by plants. Only give it a certain incentives, such as containing excessive cadmium soil acidification, activated metal ions will be absorbed by plants, heavy metal exceeds bid caused crops.

2 soil pollution repair should be suitable for national conditions

At present, the soil pollution repair on the international practice is a chemical solidifying, leaching of soil, such as electric repair, plant repair methods. Xia Jinhua speaking, these methods "zhongke hui sheng company" could do it, but some method is only applicable to industrial pollution and housing construction land treatment, it is not suitable for cultivated land processing cost is too high, moreover after repair of soil heavy metal removed, beneficial nutrients removed at the same time, also turned into "dead soil", so obviously can not be used in land restoration.

At present, the world in terms of arable land, heavy metal pollution repair, there is little precedent can be used for reference, although Japan has decades of management experience, but the cadmium pollution to an acre of land into rice fields or the cost of 1 ~ 20000 yuan, this is obviously not suitable for China's national conditions. State of soil and different countries is different, even the same country in different parts of the soil condition is different also, it is difficult to use a model to copy. At present, the national land is curing and passivation method is generally used to repair. Country in production to create the different practices, such as hunan "lime neutralization", "the commune soil neutralization" and "controlling oxidation method" and so on, these can play a role, but it is not very scientific methods, like "specialist treatment", it is difficult to fundamentally solve the problem.

"Zhongke hui sheng" with independent intellectual property rights of independent development and production of heavy metal contaminated soil repair material and soil conditioner (hui) no. 1, from the soil pollution control and restoration and soil and plant quality promotion at the same time, this comprehensive repair regulate soil. Test showed that mild to moderate pollution of heavy metals, on average, spending 200 ~ 200 yuan per mu repair agent 300 ~ 600 kg, crops can effectively reduce the absorption of heavy metals by 30% ~ 60%, reach the standard prescribed by the state. Last year, two pieces of cadmium pollution in hunan hui sheng 1 block, respectively, through the contrast test blocks blocking. Experiment shows that by rice quarterly (80 days), cadmium content index decreased obviously. This year, has been more than in the south to large areas of heavy metal cadmium pollution of farmland application.

3 the soil pollution need comprehensive treatment

Xia Jinhua tells a reporter, "zhongke hui sheng" actively advocate is a kind of "all-around doctor" point of view, and make "natural" rice method mode of hui sheng, is to respect the nature, restore natural, isn't it governance and management, but governance including other heavy metal cadmium in soil repair big background down to do it. Hui sheng actually contains a number one repair agent, fertilizer, conditioners and other substrates, indicate that it is a comprehensive repair. Its mechanism for high strength of soil degradation and plant health degradation under internal causes, development sets adjust soil pH, the passivation effectiveness of heavy metals in soil, the continuous cropping diseases as a whole to regulate soil health, through the rapid repair of degraded soil, reduce the transfer and enrichment of heavy metals in the soil for agricultural products. At the same time, meet the demand of plants and soil biological nutrients reduce cost, quality, yield, efficiency of green fertilizer technology system, balance, improve crop nutrition structure, enhance the absorption of beneficial trace elements. Fully stimulate native soil biological function, improve soil ecosystem health and immune ability, build based on the concept of "cure disease" at the end of the new principle and technology, disease prevention and control of soil by ecological control method to adjust crop nutrition health and soil ecosystem health.

Xia Jinhua, "rice natural" hui sheng model of maximum benefits, is the disease, both at the same time also let the soil health, increase the nutrition of the increase in the soil, remove the removal. Is a variety of pollution to soil coexist at the same time, can't simplification formula, systems thinking, want to use the concept of "combination". Soil data is dynamic, each year around the differences of soil, so the soil repair also like to see the doctor of traditional Chinese medicine, because people ShiFang, want to often review, constantly adjust repair agent formula. Cadmium pollution ultimately want to field planting management auxiliary operation to complete, therefore the operation should be as medical treatment, the first to match the most suitable prescription, the second medicine to use the most simple way, the third effect must be clear, the farmers to facilitate operation and acceptance.

The year before, the company in suzhou city, town, the town, wujiang city beside the enbridge village Zhou Shenghu circulation of nearly one thousand mu of rice paddies. Through nearly three years on soil conditioning repair, the reporter saw, now looks like the rotation of wheat is quite good, pull the tree to mature wheat and see root is very rich, shiny black soil, healthy and fertile. Summer chairman said: "this is the function to regulate repair agent, last year to repair a year many kinds of rice per acre to harvest more than 1100 jins. The indescribably enough rice smell, rich nutrition, especially suitable for pregnant women and children, to 30 yuan a jin."

"Through our practice, the soil pollution control and repair the key is to consider, after repair can't form secondary pollution soil. Our crop straw all offer and sell livestock enterprise around, or environmental protection. The soil after comprehensive repair always present health status, and fertilizer of soil, adequate nutrition, plant diseases and insect pests of crops is less. Therefore, fertilizer applied reduction, less pesticide threw, it not only conforms to 'ShuangJian zero growth, also significantly improved the crop quality. We believe that the soil and people, if ill, see general doctor might be a bit faster and better completely." Xia Jinhua said.
