3 since there is no obvious difference of soil respiration in the tendency in different fertilization patterns , the mean soil respiration can be regarded as the soil respiration of whole growth period in maize ecosystem 3由于在生育期内不同农作模式下土壤呼吸速率趋势无显著差异，故可以用玉米田平均土壤呼吸量作为玉米田生态系统在生育期的土壤呼吸量。
The estimation methods of water requirement , and determination of basal crop coefficient and soil evaporation coefficient under the controlled alternative furrow irrigation in summer maize were studied and verified in the fifth chapter （ 4 ）夏玉米田棵间土壤蒸发主要发生在灌后几天表层土壤比较湿润的时期内，其中表层土壤含水率和叶面积指数是影响土面蒸发的两个基本因素。
Recent studies of milkweed plants in and around the cornfields of maryland nebraska and ontario report far lower levels of bt pollen ranging from just six to 78 grains of bt corn pollen per square centimeter of milkweed leaf surface 最近在美国马里兰州内布拉斯加州和加拿大安大略省的玉米田所作的研究发现，不管在田里或附近，马利筋叶片上的玉米花粉粒更少，每平方公分只有6 78颗。
I explained to them that they have corn fields here and the corn is all picked but then theres an ear that may fall here and another ear that may fall there and they dont hire people to pick it up . if we want to go there and pick up those pieces of corn we may do so 我向他们解释，那些玉米田在收割后，一粒一粒玉米会散落在田里各处，他们不会雇人去捡这些玉米如果我们要去捡玉米的话，他们会欢迎我们。

The results show that the interface between the cultivated layer and the plough sole in the soil profile was undulated under the current cropping system mainly using small - sized four - wheeled tractors and flat under the cropping system of deep plowing annually in the fall 结果发现，现行的以小四轮拖拉机为主要动力的耕作制度下，土壤剖面中耕层与犁底层的界面为“波浪型” ，而年年进行秋翻的玉米田，其耕层与梨底层的界面为“平面型” 。
The experiment applied four soil surface treatments ( one control and three pam coverage rates : 80 % , 60 % , 4 % ) . after corn seeds were planted , granular pam mixed with loess soil was spread to cover the soil surface . two replicates were adopted in the experiments 在实验区挑选一块坡面相对比较均一、坡度在5 7的连片玉米田，分别在玉米田的土壤表面采用4个不同的处理：即pam覆盖率80 、 60 、 40和对照，实验采用两个重复。
