聚丙烯酰胺在水土流失的防護(hù)中怎么使用?

       以前提到水土流失,大家想到的方法一定是用種植植物來(lái)防止水土的流失,這確實(shí)起到了一定的作用,隨著工業(yè)的快速發(fā)展,用種植的方法已經(jīng)跟不上了,那么現(xiàn)在有什么好的方法可以預(yù)防水土流失呢?那就是聚丙烯酰胺!一提到聚丙烯酰胺大家想到的肯定與污水有關(guān),心里肯定疑問(wèn)它怎么和水土流失有關(guān)?今天廠家來(lái)揭秘其中的秘密
      聚丙烯酰胺防治田間水土流失機(jī)理
      聚丙烯酰胺是一種高分子聚合物,它具有平面網(wǎng)格和立體網(wǎng)格結(jié)構(gòu),并極易溶于水.通過(guò)大量試驗(yàn)得出:當(dāng)其溶解于水,并與土壤顆粒發(fā)生作用時(shí),能夠改善土壤結(jié)構(gòu),增強(qiáng)土壤水穩(wěn)性,提高土壤抗水蝕能力.通過(guò)試驗(yàn),還優(yōu)選出了適宜劑型及經(jīng)濟(jì)用量。
      聚丙烯酰胺增大了土壤的沉降系數(shù)
      將聚丙烯酰胺溶解于水,配成不同濃度的水溶液,并均勻噴施于土壤表面,使其與土壤顆粒充分結(jié)合,同時(shí),對(duì)照土樣均勻噴施等體積的清水.經(jīng)取土樣試驗(yàn)檢測(cè),聚丙烯酰胺處理后的遼西砂壤土沉降系數(shù)由原來(lái)的158%增大到172%,比對(duì)照土樣相對(duì)增加了9%;遼北中壤土由144%增大到161%,輕壤土也相對(duì)增加了8%.這些變化表明,聚丙烯酰胺能夠增大土壤的沉降系數(shù),有利于提高土壤的抗水蝕能力。
      聚丙烯酰胺能夠改善土壤結(jié)構(gòu)
      對(duì)施用聚丙烯酰胺的土樣品與對(duì)照土樣進(jìn)行了檢測(cè),結(jié)果施用聚丙烯酰胺的土壤的分散系數(shù)減少了7.1%~28.6%,結(jié)構(gòu)系數(shù)增大了3.2%~7.7%,說(shuō)明聚丙烯酰胺增強(qiáng)了土壤的結(jié)構(gòu)性能,提高了土壤的整體性.
      聚丙烯酰胺改善了土壤的滲透性
      觀測(cè)結(jié)果表明,處理區(qū)土壤滲透系數(shù)比對(duì)照區(qū)增加了32%.滲透系數(shù)增大,有利于雨水入滲到土壤底層蓄積起來(lái),地表不產(chǎn)生徑流或徑流量減小,從而減少地表徑流沖刷,起到保水、保土的作用.同時(shí),還可改善土壤的通氣條件,為作物增產(chǎn)打下基礎(chǔ)。

      隨著社會(huì)的發(fā)展,科學(xué)技術(shù)不斷進(jìn)步,人類(lèi)在不斷地改造自然和征服自然,也在不斷地破壞環(huán)境,再生一系列環(huán)境問(wèn)題.人類(lèi)為了擴(kuò)大生存空間,在不斷地開(kāi)展城鎮(zhèn)建設(shè),開(kāi)發(fā)新區(qū),開(kāi)礦建廠;為了發(fā)展旅游,砍樹(shù)平山,修建亭廊閣軒等,常造成城鎮(zhèn)排水工程淤堵,破壞市區(qū)環(huán)境,加劇水土流失程度及護(hù)坡工程建設(shè)難度,這些屬于城市發(fā)展中的水土流失問(wèn)題.為了發(fā)展山區(qū)經(jīng)濟(jì),開(kāi)辟畜牧、養(yǎng)殖業(yè),但由于牲畜散放、蠶農(nóng)管理技術(shù)粗放,造成林地人踩、牲畜踐踏,林下無(wú)草;蠶場(chǎng)養(yǎng)殖失衡,造成次生沙化等,產(chǎn)生農(nóng)村新的水土流失的問(wèn)題.上述這些以及其它方面水土流失的治理問(wèn)題,促進(jìn)了聚丙烯酰胺在防治水土流失領(lǐng)域試驗(yàn)研究工作的進(jìn)一步深入和廣泛推廣,聚丙烯酰胺在防治水土流失領(lǐng)域的開(kāi)發(fā)和應(yīng)用,具有深遠(yuǎn)的歷史意義和重大的現(xiàn)實(shí)意義,其應(yīng)用潛力很大。

英文版:How to use polyacrylamide in soil erosion protection?



Before mentioned soil erosion, we think of the method must be used to plant plants to prevent soil erosion, which does play a certain role, with the rapid development of industry, with the method of planting has been unable to keep up, so now what good method can prevent soil erosion? That's polyacrylamide! When it comes to polyacrylamide, what you think of is definitely related to sewage, and how is it related to soil erosion? Today, manufacturers reveal the secrets

Mechanism of polyacrylamide on soil erosion control in field

Polyacrylamide is a kind of polymer, which has planar and three-dimensional grid structure and is easily soluble in water. Through a large number of experiments, it is concluded that when it is dissolved in water and interacts with soil particles, it can improve soil structure, enhance soil water stability and enhance soil water erosion resistance. The suitable dosage form and economic dosage were optimized through the experiment.

Polyacrylamide increases the settlement coefficient of soil

Polyacrylamide dissolved in water, mixed into different concentrations of water solutions, and evenly sprayed on the surface of the soil, so that it fully combined with soil particles, at the same time, control soil samples evenly sprayed with equal volume of water. The soil sample test showed that the settlement coefficient of the west Liaoning sand loam after polyacrylamide treatment increased from 158% to 172%, 9% higher than that of the control soil sample. The medium loam increased from 144% to 161%, and the light loam increased by 8%. These changes indicate that polyacrylamide can increase the settlement coefficient of soil and improve the ability of soil to resist water erosion.

Polyacrylamide improves soil structure

The soil samples treated with polyacrylamide and the control soil samples were tested. The results showed that the dispersion coefficient of the soil treated with polyacrylamide decreased by 7.1% ~ 28.6%, and the structure coefficient increased by 3.2% ~ 7.7%, indicating that polyacrylamide enhanced the soil structural properties and improved the soil integrity.

Polyacrylamide improves the permeability of the soil

The observation results show that the soil permeability coefficient in the treated area is 32% higher than that in the control area. The increase of the permeability coefficient is beneficial for rainwater to infiltrate into the soil bottom and accumulate, and there is no runoff or decrease of runoff on the surface, so as to reduce the surface runoff erosion and play the role of water conservation and soil conservation. At the same time, it can also improve soil aeration conditions, and lay a foundation for crop yield increase.

With the development of society and the continuous progress of science and technology, human beings are constantly transforming and conquering nature, but also constantly destroying the environment and regenerating a series of environmental problems. In order to expand the living space, human beings are constantly developing urban construction, developing new areas, mining and building factories; In order to develop tourism, cut down trees and flat mountains, build pavilions, corridors, pavilions, etc., often cause urban drainage engineering blockage, damage to the urban environment, aggravate the degree of soil erosion and slope protection engineering construction difficulty, these belong to the problems of soil erosion in urban development. In order to develop the economy in mountainous areas, animal husbandry and breeding were opened up, but because of the loose release of livestock and the extensive management technology of sericulture, the forest was trampled by people and livestock, and there was no grass under the forest. Silkworm farm breeding imbalance, resulting in secondary desertification and so on, resulting in new soil erosion problems in rural areas. These and other problems of soil erosion, promote the polyacrylamide in the field of prevention and control of soil erosion experiment research further in-depth and extensive promotion of polyacrylamide in the prevention and control of soil and water loss in the field of development and application, is of great historical significance and great realistic significance and has a great potential for its application.
