抗旱

Based on the average subordinative value, the drought resistance of different cultivars of maize was arranged.

传统的作物抗旱研究是在干旱条件下进行的产量鉴定，程序复杂，工作量大，效率低。

The drought resistance of Chinese Wild Vitis species was studied by shape index, relative water content, and relative plasma permeability under the conditions of drought stress, and evaluated by subordinative function.

本研究以中国葡萄属野生种8个种11个株系，欧洲葡萄2个品种，河岸葡萄及燕山—1×河岸葡萄107株F_1代杂种共122份材料为试材，调查了盆栽干旱胁迫条件下叶片的形态变化指标，测定了相对含水量和细胞膜相对透性两项指标；以隶属函数法为手段处理这三项指标，对供试的葡萄属植物的抗旱性进行了综合评价。

The working performances of a tine and a subsoiler with adjustable wings were compared based on the soil surface condition of conservation tillage and the requirement of subsoiling.

保护性耕作条件下深松的特点与要求深松法是利用深松铲疏松土壤，加深耕层而不翻转土壤，达到调节土壤三相比、改善耕层土壤结构、减轻土壤侵蚀、提高土壤蓄水抗旱能力的目的。

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。

All these last few days the farmers have been busy fightingdrought.

在最后这几天里，农民曾经忙于抗旱。

By optimizing the culture conditions, the present work developed for the first time an efficient system for inducing embryogenic callus formation and plant regeneration through somatic embryogenesis from both dune reed, an ecotype with drought tolerance growing in desert region of northwestern China and local swamp reed .

本研究通过优化培养条件首次建立了沙丘芦苇（一种生活在中国西北沙漠地区的具抗旱性能的芦苇生态型）和当地的沼泽芦苇的体外培养体系。

Sabina wlgaris Ant. Var. vulgaris suitable to planting in arid area is a good evergreen creeper tree with the characters of cold resistance, drought resistance, poor soil resistance and shade bearing. This kind of tree can replace the lawn in city and town requiring high consuption of water.

天山圆柏是抗寒、抗旱、耐土壤府薄、耐荫的优良常绿匍匐类针叶树，在干旱区阳坡和前山带生态建设中可广泛应用，同时是城镇园林绿化中替代高耗水草坪的极佳树种。

The main studies of triticale focus on acid resistance and barren endurance ect, but the report of resistance of drought is seldom.

小黑麦抗逆性的研究目前主要集中在抗寒、抗病、耐盐碱、耐酸、耐瘠薄等方面，对其抗旱性的研究报道很少。

It\'s possibly that increase of hydraulic limitation with tree height influenced leaf water potential and turgor as well as leaf structure,which strengthened hydraulic limitation on leaf gas exchange characteristics including photosynthesis and transpiration rate, resultantly influenced carbon assimilation and CO_2 fractionation and increased water use efficiency and drought resistance capability.

应该是水力限制影响了叶片的水势和膨压、同时造成叶片的结构发生改变，而结构的改变加剧了水力对气体交换的限制、影响了光合碳同化以及对CO_2的分馏效应、使叶片的水分利用效率和抗旱性增强。

Because the large and middle irrigation works cannot effectively play the role in combating drought, farmers only can depend on the small irrigation works to combat drought, so it has caused the underproduction.

内容摘要：2005年荆门区域遭受大旱，由于大中型水利设施不能有效发挥作用，农民只能依托小水利抗旱，造成水稻因旱减产。

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。
