| 摘 要： | 以田间2年生金矮生苹果为试材研究表明。覆草、覆膜、清耕植株叶片光合速率的日变化均势相似,上午7～9时达最大值,之后逐渐降低。覆草、覆膜对光合速率日变化影响较小,但显著提高子叶片CO_2日同化量。

| Abstract: | Studies were Carried out on 2-year old field-grown Gold Spur trees, results indicated that leaves showed similar diurnal changes of photosynthetic rate (Pn) regardless of trees grown in straw or film-mulched or on mulched soils. Pn reached a maximum at 7:00 ～9:00A. M., then declined gradually until sunset. Straw or film mulching over the soil had little effect on Pn diurnal changes, but significantly increased leaf daily CO_2 gain. |
