在耕升以及整个同德集团的规划中，其零售策略定位在非公版显卡，为高端模组推出专为其进行优化的不惜工本的顶级PCB和可承受的价格。

In different growth stage, the soil pondage of R, H and Z treatments was larger than C, especially in anthesis stage, which indicated that R, H and Z could inhibit the useless evaporation of soil water before anthesis and promote grain filling. Different tillage systems had different Effects on soil pondage.

在作物不同生育时期，尤其是作物开花期，旋耕、耙耕和免耕模式的土壤贮水量高于常规耕作处理，这说明这三种模式可抑制作物开花前土壤无效蒸发，有利于促进籽粒灌浆。

Based on the actuality of agricultural ecological security and regional heterogeneity in Hunan, the paper expounds the countermeasure including: strictly control the increasing of population, choose the agricultural resource using model by adjust measures to local conditions, speed the course of agricultural industrialization, establish the investment system of agricultural ecological security, adjust energy sources structure in country, put the returning cultivated land into forest project in practice, perfect the surveillance and forecast system of agricultural ecological security, reinforce the legislation and propagandizing of agricultural environment protection, and popularize the knowledge of ecological security.

God bless the Union; it is dearer to us for the blood of brave men which has been shed in its defenses The spots on which they stood and fell; these pleasant heights; the fertile plain beneath them; the thriving village whose streets so lately rang with the strange din of war; the fields beyond the ridge, where the noble Reynolds held the advancing foe at bay, and, while he gave up his own life, assured by his forethought and self-sacrifice the triumph of the two succeeding days; the little streams which wind through the hills, on whose banks in aftertimes the wondering ploughman will turn up, with the rude weapons of savage warfare, the fearful missiles of modem artillery; Seminary Ridge, the Peach Orchard, Cemetery, Culp, and Wolf Hill, Round Top, Litttle Round Top, humble names, henceforward dear and famous-no lapse of time, no distance of space, shall cause you to be forgotten.

联邦得上帝的保佑，得勇士们为之洒血捍卫，我们对它无不感到弥足珍贵。峥嵘岁月，沧海桑田，他们曾经战斗并倒下的地方依旧；那些恬美的高地依旧；街巷里不时回响着战火喧嚣的村落也又灯火依旧；战地外的原野依旧，在那里英武的雷诺将军曾经抵御进攻的敌人，并以自己的远见卓识无私献身确保了后来两天的胜利；环绕山岗的溪流依旧，溪流岸边走来战后悠闲的耕夫，拎着残酷战场遗留下来的粗陋武器和可怖的弹片炮灰； Seminary Ridge， the Peach Orchard， Cemetery， Culp， and Wolf Hill， Round Top， Litttle Round Top，无名的，及后来的有名的，这一切都让你们感到自己的渺小。

When the mevinphos was utilized for a long time in highland barley field, the young-root of next-season cole shortened 1.9~2.0cm and fresh weight decreased 0.13~0.14g per individual plant compared with the control. Low-tillage in time after autumn-harvest showed that the weed seeds in the ground surface were harrowed into the tilth of 0~10cm. Early-low-tillage in spring-sow of the next year induced weed seeds of soil surface to germinate and come out ahead. After 10 days, tillage-sow can decrease about 40% weeds. Compared to the normal plough-row, direct late-tillage-row was postponed 10 days, and can decrease about 30% weeds. In the seedling period or later, rudimental weed seeds were handled with a hoe, which led to better cure and control effects and had more benefits to the young seedling growth and yield of the next-season crop.

研究结果表明：氟乐灵在油菜田长期使用时，土壤残留农药抑制下茬青稞幼根生长，幼根较对照株缩短3.0~3.1cm/株，鲜重量减少0.19~0.20g/株；甲磺隆在青稞田长期使用时，下茬油菜幼根较对照株缩短1.9~2.0cm/株，鲜重量减少0.13~0.14g/株；秋收后及时浅耕可将落入地表的杂草种子全耙入0~10cm耕层内；翌年春播早浅耕可诱发土壤表层的杂草种子提前萌发出苗，10d后耕种，能防除40%左右的杂草株数；较正常播种期推迟10d后直接晚耕播种，可防除30%左右杂草株数；苗期或后期拔出残余杂草种子时，除草效果理想，对下茬作物幼苗生长发育及产量无任何不良影响。

This thesis was guided by the Sustained Development Theory, exampled by the carrying out of the engineering of Anhui Province, analyzing the opportunity and challenge which it brought to us, and further, on the viewpoint of economics, researching the contradiction existing between the engineering and the economical development of local area, bring out an idea that how to improve the local economics by the turning point of the returning farmland engineering.

本文以可持续发展为理论指导，以安徽省的退耕还林实践为例，分析退耕还林给安徽农村经济发展带来的机遇和挑战，并进一步从经济学的角度来探讨退耕还林与促进区域经济发展过程中存在的矛盾，提出退耕地区应如何以退耕还林为契机，促进区域经济进一步发展的相应措施。

The results showed that different tillage patterns could improve soil water storage,the soil laer of no-tillage was covered by straws between 0 to 20 cm held water(4.542±0.894)×10~5 L/hm~2;Under no-tillage with full-straw mulching average soil temperature at 0～20 cm decreased...

结果表明：不同的保护性耕作措施均可提高土壤水分含量，其中留茬旋耕处理的土壤贮水量最高，达(4.542±0.894)×105L/hm2；在玉米播种前期及苗期，免耕覆盖处理降低土壤温度1~2℃，而整个生育期留茬旋耕处理与传统耕作处理的土壤温度相近；苗期，留茬旋耕处理的玉米株高、根长、鲜重和干重均优于其它处理，促进了玉米的生长发育；不同的保护性耕作措施均可提高玉米的产量，与传统耕作相比可增产

The results showed that different tillage patterns could improve soil water storage, the soil laer of no-tillage was covered by straws between 0 to 20cm held water (4.542±0.894)×10^5L/hm^2 Under no-tillage with full-straw mulching average soil temperature at 0~20cm decreased 1~2℃ during early corn growing period; In early season of corn growth, minimum-tillage with 1/3-straw mulching would promot the growth; Compared with the conventional tillage, economic yields could increase

Conventional tillage with bare ground, conventional tillage with straw incorporated and no-tillage with straw mulch were studied in the Hexi corridor of Gansu provience. The result showed: on summer fallow NTS stored soil water more than CTB and CTS by 30.62mm and 23.91mm, respectively; the winter storage irrigation quotas should be reduced to 900~1350 m^3/hm^2 on winter fallow; evaporation controlling rate arrived 38.1% and 7.3% at winter storage irrigation quotas 975m^3/hm^2 and 2100m^3/hm^2, respectively; NTS did not reduce ET during the spring wheat growth stage; yields different between treatments was not significant.

对甘肃河西内陆河灌区采用常规耕作、秸秆还田和覆盖免耕技术的农田水分效应进行研究，试验结果表明：在夏季休闲期，覆盖免耕比常规耕作和秸秆还田多贮水30.62mm和23.91mm；冬季休闲期可将大定额的储水灌溉减少到975~1350立方公尺/hm^2；覆盖免耕抑制蒸发率在储水定额为975立方公尺/hm^2时达到最大值38.1%，而在2100立方公尺/hm^2时最小为7.3%；覆盖免耕在作物生育期并没有减少土坡耗水量；各处理产量之间没有显著差异。

Its main advantages are: 1 Ploughshares former can Geng Sada narrow, sharp-angle, and then a small field can be competent. 2, spiral Ploughshares high-speed rotation, tillage Shulan soil formation, may omit rake mud, soil and other pressure Suitu site preparation process. 3, spiral Ploughshares work will push the soil later, will pull the machine forward traction, it can effort can be smaller engine-driven. 4, the spiral Ploughshares work itself traction to overcome the original style, to break through resistance to the plow, the machine tray can be fitted with the lower part of farming feet deep mud paddy field. 5, the spiral Ploughshares put on the handling round, you can use the drive shaft Ploughshares handling round, 20-30 cm wide in the small mountain ridge or drive to complete removal. 6, according to the plane of principle, can also be designed as a multi-Ploughshares, or a variety of forms, suitable for large-scale farming machinery Plain.

它的主要优点是：1、犁头在前能耕狭田窄地，田尖地角，再小的田地都可胜任。2、螺旋犁头高速旋转，被耕泥土熟烂平整，可省去耙泥、压土等碎土整地过程。3、螺旋犁头工作时将泥土往后推，有将机器往前拉的牵引力，因此可以省力，可用较小的发动机驱动。4、由于螺旋犁头工作时本身有牵引力，克服了原式华犁的对闯阻力，在机器下部装上托盘就可耕作深泥脚水田。5、把螺旋犁头换上小搬运轮，就可利用犁头轴的动力驱动搬运轮，在20—30厘米宽的小山路或田埂上行驶完成搬运。6、根据该机工作原理，还可设计成多犁头或各种形式，适合平原的大型耕作机械。
