选择6年生甜樱桃Cerasus avium品种红灯Cerasus avium‘Hongdeng’的试验基地开展覆草试验。覆草栽培与裸土对照交互排列，小区面积333．5m^2，重复3次，翌年开始生长调查。结果表明：覆草栽培可以使樱桃新梢旺长期提前；新梢长度、粗度、百叶质量和叶面积分剐比对照提高20．4％，30．2％，20．5％和5．3％；叶绿素质量分数和光合速率分别比对照增加了35．8％和54．7％；覆草栽培还能明显增加树体中氮、钾、钙元素的质量分数，降低铁、镁、锰元素的质量分数；覆草使根量增加，根位上升。图2表4参16

Straw mulch trial was conducted with 6-year-old cuhivars Cerasus avium ＇ Hongdeng＇ in sweet cherry orchard. As a control, bare soil was reciprocally arranged with covered region for three times in 0.033-hectare testing plots. The results showed that straw mulching could predate vigorous growth of vegetative shoot of cherry. Compared with control, the length, diameter, 100-leave weight, and dimension per leaf of vegetative shoot were increased by 20.4%, 30.2%, 20.5% and 5.3%, respectively. There had been 35.8% and 54.7% increase in the content...
