【摘要】 试验对不同杏树栽培密度(3 m×5 m,2 m×6 m,5 m×6 m)杏棉间作田内各项小候因子进行了观测,结果表明:不同间作密度杏棉间作田的太阳辐射强度、温度、相对湿度和风速发生了不同程度的变化,同一密度内行间各点小气候水平分布也有区别,其中太阳辐射强度变化较大;不同密度间相比,受光量排列顺序为3 m×5 m<2 m×6 m<5 m×6 m<CK,中测点<冠下测点<冠外测点<CK;3种栽培密度下杏树的平均遮荫度分别为49.1%,32.6%,25.9%;其他小气候因子在不同密度间和同一密度各点间没有光因子的变化大。更多还原

【Abstract】 This trial had measured all uhe microclimate factors in different apricot-cotton intercropping densities(3 m×5m,2 m×6 m,5 m×6 m).The results showed that the distribution of solar radiation intensity,temperature,relative humidity and wind speed all varied,also measurement points in the same pattern were different,solar radiation intensity had greater variance,the order of getting radiation-rate among them was 3 m×5 m< 2 m×6 m < 5 m×6 m <CK.The average shading rates of them were 49.1%,32.6% and 25.9% respectively.Other microclimate factors had less variance than the solar radiation intensity.更多还原
