耕作

In the course of the extension of subsoiling mini-till,small shar-ed subsoiler is screened from 8 kinds of tillage practices to carry outshallow plowing and interval subsoiling,shallow plowing is 7-8 cmdeep.and at the interval of 35 cm,the subsoiling is 20-35cm deep.Thus,the co-exitence of loose and compact tilths is created(ratiobetween the loose and compact tilths is 3:4).Owing to the unchan-ge of surface soil position,water,fertilizer,aeration and heat are incoordination,and yield increase is stable.when...

在试验推广深松少耕法的过程中，从八种耕作措施中筛选出用小铧杆尺深松犁，进行浅翻间隔深松，浅翻7—8厘米，间隔35厘米，深松20—35厘米，创造的虚实并存的耕层(虚实比8∶4)，由于表土位置不变，水、肥、气、热协调，增产效果稳定，种小麦、大豆平均增产分别为21.6%和15.5%；而且还有节省油料、降低成本，不用大量增添新的耕作机具的优点，并具有明显的抗旱、抗涝、防止土壤风蚀、水蚀的结果。

And the results show that long term conservation tillage is practical and effective for promoting agricultural evaluation.

研究结果表明，与传统耕作相比较，长期的保护性耕作能够较大提高农业综合效益。

According to the tillage quality was guaranteed for the minimal tilth depth and the sgnthesize property was guaranteed for the specifed tilth depth.

分析了驱动式圆盘犁耕作深度问题：根据土顺利翻转决定的最大耕深、为保证耕作质量限制的最小耕深以及综合性能最优时的额定耕深。

To further explore tillage practices for improving soil structure, the effect of different tillage practices on the structure and organic carbon of tilth soils were investigated using routine method (Wet-sieving, Potassium dichromate volumetry and Core-cutting sampling).

为了寻求能够提高土壤结构稳定性的耕作模式，在陇中黄土高原半干旱区连续7年的定位试验研究基础上，采用常规分析方法(湿筛法、重铬酸钾容量法、环刀法)，研究了不同耕作方式对耕层土壤结构性能及有机碳含量的影响。

In 2003, the wineries and wine growers in California developed "Code of Sustainable Winegrowing Practices". This code promotes farming and winemaking practices that are sensitive to the environment and responsive to the needs and interest of society in general.

2003年，加州的酒商和葡萄的栽培者制定了"可持续葡萄种植和葡萄酒酿造工艺代码"，这个规定耕作和酿造实践对环境非常的敏感，需要全社会对耕作和酿造工艺的关注。

In addition, soil carbon sequestration effects of conservational farming systems were primarily assessed based on the change of the farming system in the past 20 years in this region.

依据该区近20多年来耕作制度演变动态，对保护性耕作制度的土壤碳收集效应进行了初步估算。

The effect of different conservation tillage methods on the soil chemical property The soil organic matter was shown as that the contents of soil organic matter under conservational tillage methods were higher than conventional tillage, and the promotion under NTS was best in the depth of 0-5cm.

2不同保护性耕作措施对土壤化学性质的影响土壤有机质：保护性耕作措施有利于土壤中有机质的积累，其中NTS处理在表层(0-5cm)的改善效果最明显。

The causation of the cosmical escape are all types . such as labor style turned collective farming to petty farmer farming ; clan lived together turned to a family lived alone ; feodal bureaucracy instead the hereditary ; the annex of the earth ; natural calamity ;the corruption of the officials ; chaos caused by war and so on .

引起大规模逃亡犯罪出现的表层原因有土地兼并、苛捐杂税、自然灾害、吏治腐败、战乱侵扰等等：而深层原因则在于社会劳动方式从村社集体耕作变为小农独立耕作、基层经济组织由宗族为单位变为小家庭独立生产、政治制度由封建官僚代替世卿世禄等经济、政治制度的变化。

Roughness, surface crust, erodible fraction, stubble and time of efficacy are the indicators for appraisal. Results show that herd grazing has worst effects on soils; plowing is positive to the soils with lower erodibility and negative to sandy soils.(4) Prediction and control of wind erosion are the end of research. Two famous prediction models WEQ and WEPS were briefly introduced. On the basis of summarizing general theory and methodology for wind erosion control, some key measures are suggested for the region of Ningxia.

评价结果显示秋季耕作、春季耕作、火烧、放牧等活动使农田表层土壤风蚀加剧；（4）首先介绍了美国风蚀预测模型，在比较全面地总结前人研究的基础上，本文概括了防治风蚀的一般原理与方法，针对宁夏地区，除了改进土地利用方式外，注意可风蚀性不同的土壤应采取不同的措施。

The results indicated that the problems with which the Chinese peasants are facing include three aspects: the scale of contractual operation is small, the cultivation plots are distributed fragmentally, and the cultivation efficiency is low.

研究结果：中国农户土地承包经营规模小，耕作地块零散，耕作效率低。
