The mechanism of photosensitivity and phototaxis was studied with optical andelectrophysiological method. The results are as follows:1 among three kinds of Chysopa peral. of the compound eyes show little daily change in Chrysopa sinica Tjedar .The model and color of psesudpopupil show significant daily change in Chrysopa septempzhbybimctata Wesmacl and Chrysopa formosa Brauer, color and diameter of the psesudpopupil of the compound eyes in Chrysopa septempunctata Wesmacl make rapid change at noon, afternoon ,night are similar ,but make little change in the morning and the next morning. Diameter of psesudpopupil of compound eyes is the biggest in the afternoon, which of Chrysopa formosa Brauer, is the biggest at noon.

本文应用光学及电生理学方法对棉铃虫优势种天敌—中华草蛉、大草蛉和丽草蛉3种草蛉的感光和趋光机制进行了研究，主要研究结果如下： 1、中华草蛉、大草蛉、丽草蛉复眼伪瞳孔大小、颜色昼夜间有节律性变化，且种间具有不同的变化模式。3种草蛉中，中华草蛉复伪瞳孔大小昼夜节律变化不明显，其模式和颜色上亦基本无变化，中间为一小黑点，其外围是绿色，最外层为红色，形状为正六边形：大草蛉、丽草蛉的复眼伪瞳孔大小昼夜间不同，大草蛉的复眼伪瞳孔在中午、下午、晚上变大，早晨和次日早晨基本一致，但次日早晨稍小些。

Grass that is adapted to Qinghai-Tibet Plateau are: caragana, sand sagebrush, lucerne, sweet clover, sudan grass, ryegrass, lyme grass, astragulus adsurgens, puccinellia tenuiflora, bromus inermis, agropyron elongatum, harmel, siberian wildrye , sainfoin, tall fescue , red fescue, cynodon dactylon, zoysia, clover, bluegrass, ryegrass etc..

适合我们青海高原种植的草有：柠条、沙蒿、紫花苜蓿、草木犀、苏丹草、黑麦草、披碱草、沙打旺、星星草、无芒雀麦、冰草、骆驼蓬、老芒麦、红豆草、高羊茅、紫羊茅、狗芽根、结缕草、三叶草、早熟禾、黑麦草等；适合种植的树木品种有：雪松、青海云杉、侧柏、祁连圆柏、速生杨、落叶杉、新疆杨、青海榆树、红柳、垂榆、刺槐、丁香、云杉、沙棘、枸杞等。

As a result, synthesizing the comparison of the characteristics of drought resistance, cold tolerance, barren resistance and production of these ten grasses, we have found that the resistance of Bromus inermis,Festuca arundinacea was better , and consequently Bromus inermis , Festuca arundinacea were proofed to be favorable grasses for developing pasture in northern China in the future. Whereas, Bromus biebersteinii, Festuca rubra,Dactylis glomerata,Phleum pratense,Agropyron desertorum,Agropyron smithii,Elytrigia elongate and Phalaris arundinacea were worse, and therefore measures to local conditions and prudence in the production practice were advocated.

因此，综合抗旱性、耐寒性、耐贫瘠性及田间的生产性能的比较研究，10种牧草中的无芒雀麦、苇状羊茅的抗性表现较好，是今后我国北方地区进行人工草地建设的良好牧草种类；而草地雀麦、紫羊茅、沙生冰草、蓝茎冰草、长穗偃麦草、猫尾草、鸭茅和草芦表现不好，在生产实践中应因地制宜、谨慎推广。

In the aspect of grass cold tolerance, these ten grasses were classified into three types by the cluster analysis, based on winter survival adaptability and LT50 measured under low temperature treatment. High cold tolerance: Bromus biebersteinii,Bromus inermis,Festuca arundinacea, Agropyron desertorum,Elytrigia elongate, Phleum pretense; medium cold tolerance: Festuca rubra, Agropyron smithii,Dactylis glomerata; low cold tolerance: Phalaris arundinacea.

禾本科牧草在耐寒性方面，根据牧草越冬适应性表现和低温处理下用电导法得出的半致死温度， 10种牧草进行聚类分析结果表明：耐寒性强的是草地雀麦、无芒雀麦、苇状羊茅、沙生冰草、长穗偃麦草、猫尾草；耐寒性中等的是紫羊茅、蓝茎冰草、鸭茅；耐贫瘠性最弱的是草芦。

By the cluster analysis, 10 grasses were classified into three types—of high barren resistance: Bromus inermis,Festuca arundinacea, Dactylis glomerata; of medium barren resistance: Bromus biebersteinii,Phleum pratense,Phalaris arundinacea; of low barren resistance: Festuca rubra, Agropyron desertorum,Agropyron smithii,Elytrigia elongate.

对10种牧草进行聚类分析，得出耐贫瘠性强的是无芒雀麦、苇状羊茅、鸭茅；耐贫瘠性中等的是草地雀麦、猫尾草、草芦；耐贫瘠性最弱的是紫羊茅、沙生冰草、蓝茎冰草、长穗偃麦草。

In order to select a kind of eminent grass which is adaptable to the northern China, the present thesis studies ten kinds of grasses from Gramineae, Bromus biebersteinii,Bromus inermis,Festuca arundinacea ,Festuca rubra,Dactylis glomerata ,Phleum pratense,Agropyron desertorum,Agropyron smithii,Elytrigia elongate and Phalaris arundinacea,and also explores the physiological aspects of their drought resistance, cold tolerance and barren resistance. The drought resistance experiment was conducted to study 10 grasses under water stress during seedling stage by simulating indoor drought environment.

为了能选适应我国北方地区的抗旱、耐寒、耐贫瘠特性的优良牧草，本研究以草地雀麦、无芒雀麦、苇状羊茅、紫羊茅、沙生冰草、蓝茎冰草、长穗偃麦草、猫尾草、鸭茅、草芦为材料，在抗旱、耐寒和耐贫瘠性特性三方面的生理方面进行了探索研究。

In order to seek for the cotton glyphosate phytotoxicity safener, matches 7 effective content processing respectively with 0.1% forchilorfenur SL and 0.004% brassins AS, the bud stage time spraying, and uses effective content 2.73 g/L glyphosate 41% SL to spraying cotton, take single application glyphosate and the blank as the comparison. The results show that the forchlorfenur and the brassins are not fast to the disintoxicating effect, but have bears the poisonous effect.
