農(nóng)業(yè)灌溉和節(jié)約用水的思考

1、農(nóng)業(yè)灌溉和節(jié)約用水的思考Agricultural irrigation and waterconservation consideration我國農(nóng)業(yè)灌溉水資源存在水資源嚴(yán)肅散布不均的狀況。南邊人均 可用水量大，北方而反之，形成了南水過剩，北水過少的為難局勢。 一起，跟著我國現(xiàn)代化建造的腳步加速，大眾日子水平的進(jìn)步，公民 在工業(yè)的上、公民平常日子中對污水的排放量增多，而這些污水沒有 得到處置就直接排入水域，致使水資源受污染局勢變得更嚴(yán)肅，農(nóng)業(yè) 用水也受其影響。通過調(diào)研計算，我國灌溉用水量不只大并且存在的 糟蹋表象也是非常嚴(yán)肅，特別是水資源富余的當(dāng)?shù)貙?jié)省用水的知道 不強(qiáng)，灌溉用水運(yùn)用系數(shù)低。I

2、rrigation water resources and agriculture of our country water resource is seriously uneven distribution situation. The per capita water availability, the north and south, forming the excess, north water too little difficult situation. Together with the construction of Chinas modernization, the acce

3、lerating pace of life, the level of progress, citizens in the industry, the citizen on ordinary day of sewage discharge increased, but these have not been directly discharged into the sewage disposal of water, causing water pollution situation is more serious, agricultural water use is also affected

4、 by the.Through the investigation and calculation, the irrigation water use not only and there is also very serious waste phenomenon, especially the local water resources surplus is not strong to know to save water, irrigation water use coefficient is low.農(nóng)業(yè)上采納節(jié)水灌溉的關(guān)聯(lián)政策，對咱們生態(tài)環(huán)境的建造，經(jīng)濟(jì) 的可持續(xù)開展，進(jìn)步公民日子水平

5、等都具有重要的含義。我國是一個 地廣人多、天然資源豐富的大國，可是生齒基過大，人均所占資源少。 建造杰出的生態(tài)環(huán)境是一項長時間艱巨的使命，而節(jié)省農(nóng)業(yè)灌溉用 水，能添加生態(tài)環(huán)境中的可運(yùn)用水資源，使西部土地荒漠化的進(jìn)程變 緩，水土的丟失，一起削減大家對地下水的過度挖掘，防止地表下沉、 房子坍毀的表象。還有使得人均可到的平常日子中水增多，減輕平常 用水嚴(yán)重的現(xiàn)狀，公民能夠不必過度為無水可用的地步憂慮，這為公 民個人謀了福利，也帶來了便利。The adoption of water-saving irrigation agriculture related policy, build on our e

6、cological environment, the sustainable development of economy, progress of citizen life level has important meaning. China is a vast territory, abundant natural resources in the country, but the population base is too large, the per capita occupies less resources.Construction of ecological environme

7、nt is good is a long time arduous mission, and save irrigation water, can add the ecological environment in the use of the water resources, the land desertification is slow, soil and water loss, to cut all excessive groundwater mining, prevent the ground subsidence, the house collapsed representatio

8、n. And makes the water per capita to ordinary days increase, reduce the daily consumption of the status of serious, citizens can need not excessive concern for water level, it seeks the benefits to individual citizens, convenience.我國的農(nóng)業(yè)灌溉，怎么做到節(jié)省用水。首先是知道的疑問，節(jié)水 農(nóng)業(yè)不只是農(nóng)業(yè)灌溉節(jié)省用水，節(jié)水技能也不只是只能用于灌溉，水 資源的合理、科學(xué)、

9、最大化的運(yùn)用，需求多方面的效果。很早以前， 我國就有：南水北調(diào)，南水時運(yùn)不好的說法。所以應(yīng)加強(qiáng)特別是南邊 多水的當(dāng)?shù)厮Y源重要性、節(jié)水迫切性的教誨。關(guān)于農(nóng)業(yè)灌溉上，運(yùn) 用領(lǐng)先的技能：途徑防滲技能，低壓管道輸水灌溉技能，噴灌技能， 微灌技能。這些技能在園藝作物上用得都很老練，很多的實際通知咱 們，這些技能的運(yùn)用，資金的投入，不只沒有由于需求本錢增高而是 結(jié)尾農(nóng)人的收益受到影響。相反，由于節(jié)省了用水的本錢，它的運(yùn)用 添加了普通大眾的收益。Agricultural irrigation in China, how to save water. The first is that the questi

10、on, water-saving agriculture is not only the agricultural irrigation water saving, water-saving skill is not only used for irrigation, using reasonable, scientific, maximum water resources, demand side effect. Long ago, our country has: the South-to-North Water Transfer Project, the bad timing. So s

11、hould strengthen especially south water and local water resources, water-saving urgent importance. On agricultural irrigation, with leading skills: way of anti-seepage ability, low pressure pipe irrigation sprinkler irrigation skills, skills, skills. These skills in horticultural crops used are very

12、 sophisticated, many actual notice us, use these skills, capital investment, not because of increased demand cost but end farmers income affected. On the contrary, the saving water costs, its application to add the general public benefits.其次，好的技能的運(yùn)用也離不開科學(xué)的辦理。節(jié)水經(jīng)營辦理技能 是樹立農(nóng)田高效用水的運(yùn)轉(zhuǎn)辦理體系，主要是樹立習(xí)慣社會主義市場 經(jīng)

13、濟(jì)條件下的農(nóng)田用水辦理機(jī)制和價格體系。現(xiàn)農(nóng)業(yè)水資源的辦理還 存在許多缺點，傳統(tǒng)的節(jié)水灌溉工程的投入機(jī)制是單一國家擔(dān)負(fù)是以 物質(zhì)資金的方法投入。在市場經(jīng)濟(jì)的機(jī)制下，這樣的政策就不利于我 國農(nóng)業(yè)節(jié)水的開展。Secondly, to make good use of skills are inseparable from the scientific. Water-saving management skills is to establish the farmland water use efficiency operation management system, main is to establish the habit of socialist market economy under the conditions of agricultural water management mechanism and price system. For the agricultural water resources still exist many drawbacks, the input mechanism of w
