通过调查研究，认为晋西北农业生产应该注意以下几点：①在土地利用结构调整中，建设坡耕地退耕种草、饲料玉米、豆科杂粮和抗寒果树的4类用地结构；②在农业生产中，促进生产的机械化、集约化和产业化水平；③加大地膜覆盖推广力度，尤其是宽幅地膜的推广、增施化肥和有机肥、引进良种、农田保护性耕作与粮草轮作技术和病虫害防治等5大类实用农业技术。

Will adopt the form of inferior and provisional tax rate 2009, reduce the productivity raw material with partial home bigger demand to import custom duty appropriately, continue to carry out partial rolled steel cancels to export custom duty since December 1, 2008, adjust the chemical fertilizer such as urea exit is seasonal the policy of custom duty, the tax rate of special export custom duty that lowers partial chemical fertilizer and its raw material at the same time.

另一方面，根据国内市场供需变化情况，取消豆饼、猪肉、印楝油的进口暂定税率，恢复为最惠国税率。同时，为保障国内农业生产用肥的需要，继续对尿素、磷酸氢二铵等化肥出口征收季节性出口关税，继续对复合肥等部分化肥及其原料征收特别出口关税。二是支持高新技术发展，鼓励企业自主创新，推动产业结构升级，促进振兴国内装备制造业。

Thesources of self-pollution in agriculture production of Shanghai suburbs are mainlythe agriculture pesticides,chemical fertilizers,urine and excrements of fowls and animalsand the agriculture plastic films at present. Before the seventies,organic mercury pesticides and organic chlorine pesticides wereused in Shanghai suburbs.It influenced the environment greatly. During the eighties,thepesticides making great influence were mainly organic phosphorus and tyiethroids;the fer-tilizer causing great influence ...

上海市郊农业生产中的自身污染，目前主要有农药、化肥、畜禽粪尿和农用塑料薄膜。70年代以前，上海曾施用过有机汞、有机氯等农药，对环境的影响较大。80年代以来，影响较大的农药主要是有机磷和菊酯类；化肥主要是氮肥施用过多，导致蔬菜硝酸盐含量过高；畜禽粪尿已成为郊区突出的新污染源，造成水体的严重污染；各类农用塑料薄膜也是必须重视的新潜在污染物。

On one hand,agricultural products supply has turned from being in shortage to abasic balance in total amount,and after our country joins WTO,the agricultural products will face the fierce international market competition,and market demand is larger and larger to the engagement which agriculture will be developed;On the other hand,with the abuse of chemical fertilizer and agrochemcals,the agricultural ecological environment worsens sharply and harmful substances remained in agricultural products increase constantly,thus impair agricultural product quality and the improvement of its benefit,restricting the sustainable development of ecological agriculture too.

一方面，农产品供给已由短缺向总量平衡，加入WTO后，农产品又面临激烈的国际市场竞争，市场需求对农业发展的约束力越来越大；另一方面，随着化肥、农药的大量使用，农业生态环境急剧恶化，农产品残留的有害物质不断增加，影响了农产品质量和效益的提中国标准化研究院高，也制约着生态农业的可持续发展。

L Lawfully supervising agricultural ecology protection tasks, organizing ecological and sustainable agriculture tasks; supervising water resources utilization and exploration for fishery, being responsible for the protection of aquicolous and wild animals and plants; supervising utilization and exploration of rural energy resource.

研究提出种植业发展的法规、政策和战略、规划、计划建议，指导种植业生产及结构调整，研究提出并组织落实种植业发展的重大技术措施；提出耕地保护、补偿与改良的政策措施；指导救灾备荒种子、化肥等生产资料的储备、安排；组织化肥、农药、农膜、种子等产品的质量监督、检验、登记；组织种子及其资源的品种审定和进出口审查，指导农业植物内检工作。

The result showed that:(1) the unrenewable industrial assistance emergy were mainly in the region of farming eco-economic system, and the chemical fertilizers greater impacted on agriculture output;(2) the intensity of emergy use was higher than the national average on agriculture, which indicated that there were a higher levels of investment in science and technology in the region;(3) the net output rate of emergy in the planting economic ecosystem was higher than the level of the national average and developed regions of guangdong province, which showed that the system had higher economic vitality, and the better function of agricultural system, more efficient operation, higher returns of emergy;(4) the rate of environmental loading was a lower level, which indicated that agricultural production had less pressure on the entire regional ecosystems, and caused less damage to the ecological environment, and agriculture, environmental resources for further development and utilization;(5) the sustainable development index in yanqi basin indicated that farming systems in the region belonged to sustainable development areas.

结果表明：(1)焉耆盆地绿洲2006种植业生态经济系统的能值投入以不可更新的工业辅助能为主。在不可更新工业辅助能中，化肥对农业的产出影响较大；(2)该区域的能值利用强度高于全国平均水平，说明农业的科技投入水平较高；(3)系统的净能值产出率高于全国平均水平和发达地区水平，表明系统具有较高的经济活力，农业系统整体功能较好，运转效率较高，能值回报率较高；(4)农业生产对整个区域生态系统的压力较轻，引起的生态环境破坏较小，农业环境资源还有进一步开发利用的潜力；(5)焉耆盆地种植业系统具有可持续发展的潜力。

Due to food pressure, grain product in the western Jilin Province will be enhanced in the near future. Farmland areas in the area will be decreased slowly in the near future, but with the technique development of irrigation establishment, paddy areas and utilization amount of fertilizer and pesticides will be increased rapidly. So, the NPS pollution from farmland will be more serious. The main lakes in the areas such as Moon Lake and Qagan Lake have been polluted by N and P, and the content of salt in the Nenjiang River has been increasing since last 30 years. All of these show that the negative effects of NPS pollution in the area have been serious and should not be neglected by the scientific research and corresponding government management. To deal with the contradiction of agriculture development and water pollution, the trend of increasing paddy area and using amount of fertilizer, pesticide and herbcide in the western Jilin Province should be controlled. Also, the drainage of return flow from paddy should be controlled and return flow should be disposed with ecotechniques by use of the large areas of lakes and mires in the area. Through these measures, the quality of surface water could be protected and the degeneration of ecoenvironment in the area could be contained.

我国由于粮食压力，未来吉林西部的粮食生产还将进一步加强，随着种植业结构的调整，垦殖率会略有下降，但随灌溉设施的建设与完善，水田面积将进一步扩大，化肥、农药的用量还将快速增加，农业活动引起的非点源污染将更加突出，而研究区的主要湖泊月亮湖、查干湖目前已达中等富营氧化水平，嫩江水质的咸化趋势明显，因此农田非点源污染物的流失及其内流区外流化面积的增加对地表水体富营养化、咸化的作用愈来愈明显，农田非点源对地表水水质的影响已不容忽视，应引起社会的关注，为协调农业发展与水污染这一矛盾，吉林西部应遏制化肥、农药施用量增长过快和水田过度开发的势头，控制洗盐回归水的排放量，利用区内广泛分布的大量泡沼对农田径流和回归水进行生态处理，既保护了地表水的水质，又有利于生态环境的改善。

Currently as China's accelerating development of agricultural industrialization and the increase of the agricultural production investment, the demand for chemical fertilizers increases year after year. Simultaneously as China's scientification in fertilization and fertilization ratio of the nitrogen, phosphorus, and potassium fertilizer tending to be reasonable, the chemical fertilizer demand structure will possibly change, the chemical fertilizer market environment will also change, the chemical fertilizer industry will run to the direction of high efficiency and environmentally no harm. Comparing to ordinary urea, large urea has many merits. These merits include big rime, glabrous pellet, smooth and well-mixed, not easy to crush or agglomerate in moist environment, suitable for long distance bulk transport and storage, and so on.

目前随着我国农业产业化的不断加快发展和对农业生产投入的增加，化肥的需求量在逐年上升，同时随着我国农业施肥的科学化，氮、磷、钾肥的施用比例趋向合理，化肥需求结构可能发生变化，化肥市场环境也会发生变化，需求旺盛的化肥业将向高效、环保等方面转化；大颗粒尿素与普通尿素相比，具有结晶大、颗粒光洁、圆滑、均匀，不易粉碎和吸潮结块，具有适合长途散装运输和存贮等优点。
