中文拼音 [hànyècǎo]
旱葉草
英文
bear grass-
( 3 ) wheatgrass could reduce water dissipation by shutting up stoma and let some leaves wither
3 、冰草植株在乾旱條件下關閉氣孔，以減少水分散失，葉片萎蔫，以減少蒸騰面積。Through cultivating five cold - season turfgrass ( lolium perenne, agrostis stolonifera, festuca rubra, festuca arundinacea, bromus inermis ) in basin, their drought to lerance indexes, including the planting height, the root growth, the relative water content of leaves, the penetration of membrane, were comprehensively evaluated to compare their drought tolerance
摘要採用盆栽育苗法，在5種冷季型草坪草苗期連續乾旱脅迫下測定植株高度，根系生長，葉片相對含水量和質膜透性等抗旱指標，以綜合評價5種冷季型草坪草的抗旱性能。The results showed that the best water management pattern of fuji apple orchard was wheat straw mulching under low annual precipitation and grass planting under high annual precipitation. the comprehensive analysis was carried out on effects of different water management patters on yield of fuji apple, soil water conservation and soil organic matter of fuji apple orchard, growth in various stages and fruit quality of fuji apple under different annual precipitation
結果表明，在乾旱年份，紅富士蘋果園水分管理模式以秸稈覆蓋方式最佳，在多雨年份，紅富士蘋果園水分管理模式以果園種植白三葉草方式最佳；並綜合分析了不同降水年型不同水分管理模式對紅富士蘋果產量的影響，不同水分管理模式對果園土壤含水量和土壤有機質的影響及不同水分管理模式對紅富士蘋果生長狀況、外觀品質、內在品質的影響。Han xing 58 % water soluble granules is none selective systemic herbicide by foliar application, which has advantages of wide control spectrum, quick effect, water - fast, easy to use and transport in long distance
旱星是一種滅生性內吸傳導型莖葉處理除草劑，具有殺草譜廣、使用方便、見效快、耐雨水沖刷、適宜遠途運輸等特點。Ecological characteristics of pogonatherum paniceum ( lam. ) hack. indicated that the transpiration was reduced by its small leaf area, and inner rock water can also be up taken because of its strong roots system. therefore, it could grow on rock surface and rock aperture
金發草生態特徵分析表明，其葉片面積較小，減少了葉的蒸騰，降低水分的散失；根系發達、根厚而平展，可在巖石表面或巖石縫隙生長，根系可吸收巖石表層和縫隙中的水分，對乾旱具有較強適應能力。Thirdly, this paper compared the different responses of plants to these two stresses, the change of the defensive enzyme activity and the rate of losing water of leaves was different at two different stresses. the rate of losing water of leaves at drought stress was more rapid than that at salt stress, the leaves would wither and the change of activity of enzymes notably at drought stress, these results showed that the damage to plants was result from the oxidation at drought stress. at salt stress, the content of relative water of leaves changed slightly as well as did the activity of enzymes, these results showed that the damage to plants was caused by poison of ion and lack of nutrition
三、通過研究兩種冰草植物對兩種脅迫的反應指出乾旱脅迫和鹽脅迫通過不同的途徑對植物進行傷害，主要表現在葉片的失水速率和保護酶活性的變化，乾旱脅迫短時間內葉片失水速率很快，葉片萎蔫，引起保護酶活性顯著變化，表明乾旱脅迫主要是通過氧化脅迫對植株造成傷害，而鹽脅迫下葉片相對含水量幾乎保持不變，表明鹽脅迫對植物的傷害主要通過離子毒害和營養虧缺造成。分享友人
