Correlation Analysis between Natural grass Height,Yield,and Meteorological Factors in the Shuangjingtan Area from 2020 to 2021
The twin well beach area grew perennial shrubs,semi-shrubs and herbs,with good ecological environment.Analyzed the correlation between forage grass growth and air temperature and precipitation in the twin well beach area from 2020 to 2021,which provided some reference for the smooth development of forage grass and animal husbandry in Alxa.The results showed that:(1)the height of red sand,Bawang and red thorn is positively correlated with air temperature,and the correlation between red sand(P<0.01)and Bawang(P<0.05)and air temperature is significant,and air temperature.(2)In terms of the correlation between shrub and semi-shrub height and precipitation,overlord,red sand and red thorn are positively correlated with precipitation,and the herbaceous plants and grass are positively correlated with precipitation.(3)Bawang fresh weight is positively correlated with temperature,other shrubs and semi-shrubs are negatively correlated with temperature,Gobi needle grass fresh weight is negatively correlated with temperature,and fresh weight of missing grass is positively correlated with temperature.(4)In 2020 and 2021,the forage yield was positively correlated with precipitation,in which the fresh weight of the grass was significantly correlated with precipitation.
