Resistance responses were studied in different Arabidopsis ecotypes after being inoculated by some important plant pathogens. According to the results, molecular mechanisms of resistance and expression of the defense-related genes in resistance and susceptible Arabidopsis ecotypes were studied. Results followed in this paper.All the 11 Arabidopsis ecotypes tested were incompatible to Erysiphe convolvuli, Alternaria brassicicola, Setosphaeria turcica and Verticillium dahliae.

本文在对拟南芥不同生态型接种不同植物病原菌后的抗病反应基础上对抗感表现不同的生态型的抗性机制及抗性相关基因的差异表达进行了研究，结果如下：测定拟南芥11个生态型接种8种不同植物病原菌后发现，供试拟南芥对田璇花白粉病菌、白菜黑斑病菌、玉米大斑病菌和棉花黄萎病菌均表现为非亲和反应。

"Quillagua cannot resist much longer," said Alejandro Sanchez, 77, pointing a cane at a parched, grassless field where he once grew corn and alfalfa.

77岁的阿雷杭德罗·桑契兹用手杖指向一块他种过玉米和紫花苜蓿、现已枯乾寸草不生的田说：「基亚瓜再也撑不了多久了。

The purpose of researching the fields of stubble is that corn stalks will be aimed at post-harvest stubble part, above ground and below-ground stubble of the main stem and crush evenly Hunban in the topsoil, To loose soil and increase soil organic matter, improve the physical properties of the soil, increase the aggregate structure function.

本课题研究的灭茬还田机，目的在于将玉米秸秆收获后的根茬部分、地面以上留茬及地面以下主茎部分粉碎并均匀地混拌在耕层中，达到疏松土壤、增加土壤有机质、改善土壤物理性质、增加团粒结构的功用。

The CO2 effluxes from the soil showed exponential responses to the air temperature with significant correlative coefficient (from 0.84~0.87 under different straw management, irrigation and nitrogen application strategies).

为探讨不同农作措施条件下的农田碳平衡规律，研究农田对大气CO_2的源汇特征，2000年至2003年用钠石灰碱吸收法连续测定不同秸秆还田、灌溉和氮肥施用等农作措施下京郊冬小麦—夏玉米轮作体系作物生长季的土壤呼吸。

Microbial biomass carbon and microbial biomass nitrogen, respiration CO2 and mineralized nitrogen in plant straw fertilized soil were determined under laboratory incubation conditions of constant temperature and moisture based on field above- ground yields of intercropped sweet maize straw and white clover straw.

根据田间甜玉米／白三叶草套种各作物的秸秆产量，在恒温恒湿条件下进行室内培养，探讨秸秆不同方式还田后土壤微生物量碳、微生物量氮、呼吸产生的CO2和矿化产生的无机氮的变化规律。

The study indicated continous corpping for years, planted inresist disease varieties, unusual climate, lacking of scientific methed of prevention and cure, returning maize straw to infield are major factors to creat head smut.

研究表明，玉米连年重茬，种植感病品种，气候变化异常，缺乏科学的防治措施及部分地区推广的秸秆还田是诱发丝黑穗病发生的重要因素。

Aventis company exploited Isoxaflutole with sulfone structure which was a good herbicide against weeds of maize and sugar beet fields.

安万特公司开发的异恶唑草酮是一种含砜结构很好的玉米、甜菜田苗前、苗后广谱除草剂。

The effects of returning different amount maize straw into field (0, 9 000 kg/hm^2, 12 000 kg/hm^2, 15 000 kg/hm^2) on winter wheat flag leaf photosynthesis pigment and the photosynthesis characteristic in the grout stage were studied by field experiment.

通过田间试验探讨玉米秸秆不同还田量(09 000 kg/hm^2、12 000 kg/hm^2、15 000 kg/hm^2)对接茬冬小麦灌浆期旗叶光合色素及光合特性的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
