四翅滨藜在山西不同降水条件下的生长状况研究

2009年3—10月,采用盆栽试验方法,研究四翅滨藜(Atyiplex canescens)在山西不同降水条件下的生长状况,结果表明,四翅滨藜在年降水量200mm以上可以正常生长,且生长高峰在6月至8月,随着年降水量的增加,其生长速率也明显加快;年降水量从200mm增加到400mm时,增速变化较明显;年降水量达600mm时,接近增加极限。

Growth Situation of Atyiplex canescens under Various Precipitation Conditions in Shanxi

With pot experiment, the growth situation of A tyiplex canescens under Shanxi precipitation was studied from March to October in 2009. The results showed that Atyiplex canescens had a normal growth when local precipitation was above 200 mm and the growing peak appeared during June to August. The growth rate increased with the increase of the annual rainfall and when the annual rainfall increased from 200 mm to 400 mm, it showed a remarkable increase and the growth rate reached the limit when the annual precipitation was 600 mm.
