The autumnal changes in contents of carbohydrate,soluble protein and the enzyme activities of catalase(CAT)and superoxide dismutase(SOD)in tLe root of Clinelymus nutans (griseb Nevski were studied in the cold mou- ntain areas.The results showed that both the contents of carbohvdrate and soluble protein and the enzyme actlvity of the CAT and SOD increased with the temperature decrease in Autumn and early Winter;and these four attri- butes were higher in the forage root collected in the burned grassland than that in the non- burned grassland. Since the high contents of carbohvdrate and protein in the forage root at the end of Autumn could provide energy for forage to resistant cold in Winter and provide nutrients for forage ger mination in the following year,the forage in the burned grassland grew be- tter than that in the non- burned grassland.The high enzyme activitv of the CAT and SOD in the Autumn was also related to a high resistance to low temperature.

本文研究了秋季高寒山区垂穗披碱草(Clinelymusnutans)根系中碳水化合物、蛋白质含量和过氧化氢酶(CAT)和超氧化物歧化酶(SOD)活性变化及与牧草抗寒性的关系。结果表明,秋季随着气温的下降,牧草根系中碳水化合物和可溶性蛋白质含量增加,CAT和SOD活性增强。其中火烧地的全期平均碳水化合物、可溶性蛋白质含量和CAT、SOD活性明显高于未火烧地,总增幅度也较大。秋季牧草根系中碳水化合物和可溶性蛋白质含量增加是多年生牧草贮藏能量物质安全越冬和翌年再生芽萌动的能量需要,而CAT和SOD活性的增强可阻止低温下细胞中氧自由基的积累,使植物生物膜系统免受伤害,是决定植物抗寒性的另一重要因子。火烧地牧草春季萌动早,长势强,产量高,秋季其根系中碳水化合物和可溶性蛋白质含量高及CAT和SOD活性强是重要原因。

Sheep night penning on pasture infected by grass grubs strongly controlled the grass grub population and was helpful to the rccovery of the grub-damaged pasture in the camping area by improving soil nutrient availability and root-soil contact.Mob night penning has proved to be a cheap, efficient and practical technique of pasture manage-ment.This study suggested that effectiveness of grub control by night penning in-creased with the increase in instocking rate. Inview of pasture recovery,the stocking rate of 4000~5000 sheep/ha for 4 nights had the best result.

羊群在受到蛴螬严重为害的草地上宿营,对蛴螬数量有显著的控制作用,并能有效地改善土壤养分状况,促进受害牧草根系恢复生长,从而有利于草地植被的复壮更新,因而是一种廉价、有效、易行的草地管理技术。研究结果表明,对蛴螬的控制效果随载畜率的提高而增强,而就草地恢复情况而论,以载畜率为4000~5000只羊/公顷、连续宿营4天的处理效果最为显著。

The experiments were conducted to study changes in content of Carbohydrate and activities of protecting enzyme in root of Clinelymus nutans planted in differently treated soils during the germination in spring; The results showed:(1) The more the forage's root kept Carbohydrate the higher the activities of protecting enzyme were in winter,the earlier it ger-minated and the more hardy it was in spring.(2) The contents of soluble sugar an activities of SOD, POD in root of Alpine forages were reduced with increasing...

The experiments were conducted to study changes in content of Carbohydrate and activities of protecting enzyme in root of Clinelymus nutans planted in differently treated soils during the germination in spring; The results showed:(1) The more the forage's root kept Carbohydrate the higher the activities of protecting enzyme were in winter,the earlier it ger-minated and the more hardy it was in spring.(2) The contents of soluble sugar an activities of SOD, POD in root of Alpine forages were reduced with increasing of temperature and raised with decreasing of temperature. The forage planted in fired soil was more resistant to coldness because high level of SOD and POD activities in root were keeped and quickly increased by temperature drop. So change in Carbohydrate metabolism and adjustment of enzyme system were an important physiological re- sponses of forage to ecological environment.

本文研究了高寒草地3种立地条件下垂穗披碱草(Clinelymusnutans)在春季萌动过程中根系碳水化合物和保护酶活性的变化,结果表明:(1)入冬时根系中碳水化合物贮量高、保护酶活性强的牧草春季萌动早、生长快、抗寒性较强。(2)当春季气温波动式回升时,牧草根系中可溶性糖含量、SOD(超氧化物歧化酶)和POD(过氧化物酶)活性随气温上升而下降,随气温下降而上升。其中火烧地牧草根中SOD和POD酶活性一直保持较高水平,并对温度变化反应敏感,而抗寒性也较强。因此春季高寒山区牧草根内的代谢改组(增加可溶性糖)和酶系统的调节(增加SOD、POD活性)是其对生态环境适应的重要生理反应。
