耕土

The warm damp balminess of spring encompassed her sweetly with the moist smells of new-plowed earth and all the fresh green things pushing up to the air.

那春天新耕起的泥土散发出的阵阵潮湿的土香正从四面八方向她袭来，而满眼的嫩绿也在蓬蓬勃勃地向空中升腾。

The expression of mcSKD1 was most prominent in 400 mM NaCl- grown roots of hydroponically-grown ice plant.

在水耕培养植株根及叶的盐诱导表现情形变化较土耕不明显。

This paper makes the soil movement be four sections: a Cutting soil with edge; bThe soil movement along the plowshare and plow chest's below surface; c The soil movement along the plow cliff ;dThe soil movement beyond the plow in the course of farming in order to study the force of moldboard plow surface.

本文在研究犁体曲面受力时，把犁耕时土垡的运动分为四个阶段：a 用铧刃切开土垡；b 土垡沿犁铧和犁胸下部曲面运动；c 土垡沿犁壁运动；d 土壤超出犁壁曲面运动。

The effect of improvement on planosol by the application of the four types of ploughs suggest that there were hard clods between two chisel if the cultivate depth is less than 40cm; there are hard triangle clods between two chisel if the complete deep cultivate reach 40 cm and soil hardness is 20～40kg/cm〓 if the cultivate horizon is shallow or below 20 cm, the expected effect of improvement will not be obtained.

3应用三段式心土犁的土效果。不同改土机械改良白浆土对比试验结果表明：各种深松耕深不足40cm，且深松铲之间存在硬隔，达不到预想的改土效果。

With the proper coordinate system,the movement of up cut and down cut rotary blades can be incorporated in one equation,but two kinds of blades work in different angular ranges.

通过建立适当的坐标系，把正、反转旋耕刀的运动统一起来，用同一个方程表示，二者只是在不同的切土范围内工作。

Under intensive cropping with retention of crop residue management regimes, soils can become suppressive to Rhizoctonia root rot.

保留作物残体的精耕栽培制度可使土壤变为对病害有抑制作用的抑病土。

In order to find out primary and secondary factors influencing the power dissipation of corn rootstalk treatment device of no-tillage planter, soil-bin experiment was carried out in the laboratory. The power dissipation model of the device was set up based on the quadratic regressive orthogonal test of the influencing factors.

为找出影响免耕播种机玉米根茬处理装置的功率消耗的主次因素，对新研制的免耕播种机玉米根茬处理装置进行了室内土槽试验研究，对影响作业功耗的因素采用二次旋转回归正交试验，建立了玉米根茬处理装置的功耗模型。

In the traditional experimentation of farming , we must do scarification,shoveling, pressing respectively.So the time between every two working procedure is long,the efficiency is low,and it will also expand a large number of the labour force.In order to work out this problem ,we should create a new kind of machine.It can take the place of men.

传统的耕作试验需要单独进行松土、铲平、压实、旋耕等工序，各工序的间隔时间较长，效率较低，而且要消耗大量的劳动力，为了解决这一问题，我们迫切的需要研制出一种新型的机械设备，用它来代替人力。

A seven year location experiment in the condition of wheat-corn rotation of Lou soil in Guanzhong plain was conducted. The effects of the subsoiling, rotary tillage and no-tillage on the distributions of micro-aggregates and the contents of organic carbon and nitrogen in soil micro-aggregates were studied.

以7年不同耕作的定位试验为研究对象，研究了深松、旋耕、免耕等保护性耕作对关中塿土小麦–玉米轮作条件下微团聚体分布以及微团聚体中有机碳和全氮含量的影响。

We will see more and more activist government policies that distinguish economic activities according to the nationality of the actors.

我们将看到越来越多激进的政府政策，这些政策根据企业的国籍来区分经济活动。

If we can prove the independence of an axiomatic system, then we can guarantee the conciseness of this system, ie.

如果能够证明某个一阶谓词系统的独立性，那么就能够保证该系统的建立是精炼的，即没有任何一条公理或推理规则是多余的。
