Planting Masson's pine using the favourable temperature and humidity factors in the November ( popular nameis "balmy weather in the tenth lunar month" ) every year. The preserved rate of afforestation would amount to 93%. That was favourable to the root system resuming, sprouted in advance,prolonged growth period,and increased grow amount. The total tree high would be amount to 118cm in two year. The physiology characteristics value as root viability and content of chlorophyll etc. has been rise distinctly....

The preserved rate of afforestation would amount to 93%. That was favourable to the root system resuming, sprouted in advance,prolonged growth period,and increased grow amount. The total tree high would be amount to 118cm in two year. The physiology characteristics value as root viability and content of chlorophyll etc. has been rise distinctly. The time limits of suitable for afforestation, at the same time, was expanded. The tension of labour for afforestation was relaxed in spring. It would be fovourable to replantion in these year. And the unfavourable condition of afforestation was avoided in the spring.

利用每年11月份(俗称“小阳春”)适宜的温湿度进行马尾松栽植,造林成活率达93%,并有利于根系恢复,提前萌动,延长生长期,增加生长量,根系活力、叶绿素含量等生理特征值明显提高。同时,扩大了适宜造林的时间范围,缓和了春季造林劳力的紧张状况,有利于当年补植和避开春季造林的不利条件。

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.

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。

Soil moisture regimen changes with different localities of topography in Maowuse transition zone from sandy land to desert.Soil moisture distribution in sandy land(soil moisture models)and the characteristics of soil water used by sand plants(sand plant distribution models) depend on the conditions such as dune drift on slope facing the wind,dune sand on slope out of the wind and groundwater table within lowlands among dunes.The mechanism of soil water used for sand plants could be demonstrated by the following...

Soil moisture regimen changes with different localities of topography in Maowuse transition zone from sandy land to desert.Soil moisture distribution in sandy land(soil moisture models)and the characteristics of soil water used by sand plants(sand plant distribution models) depend on the conditions such as dune drift on slope facing the wind,dune sand on slope out of the wind and groundwater table within lowlands among dunes.The mechanism of soil water used for sand plants could be demonstrated by the following two aspects:the physiological and ecological processes and biomass of ground parts of sand plants,distribution of root system of sand plants and soil water environmental capacity.In the development of mobile dunes changing into fixation ones,the relationships between soil moisture dynamics after the formation of shrub communities on stabilizing mobile sand and actual evapotranspiration of shrub communities would show the regimens of soil water balance of different vegetative cover,different densities of shrub communities,different years and seasons.Cobinated with which,the application of soil moisture models could be helpful to establish and keep a sustainable and better successed community.In order to improve water utilization rate of sand plants,the following 3 aspects should be taken (1)Selecting the drought resistant species by the analysis of the characteristics of physiology,ecology and heredity of sand plants.Native species will be available for rehabilitation of individuals or communities,however,it is important to pay more attention to importing species;(2)New materials of anti-drought and soil water conserved should be used for the establishment of shrub communities of stabilizing mobile sand,especially for recover and growth of root system during the period of spring drought,such as gel-forming cross-linked polyacrylamide,water save surfactant,ctomycorrhizal fungus and other soil microbe preparations and (3) Densities of shrub communities of stabilizing mobile sand and disposition of different communities in responses to phrases of dune development should be in accordance with soil water environmental capacity. \ \
