实测分析了果园覆盖与敷盖百喜草的光照、风速、温度、相对湿度时空变化规律。冬季中午12:00时桃园比桔园光照强2陪左右,14:00时风速大3~4倍,夏季地面最高温度行间裸地比行间百喜草高20.0℃,株间裸地比敷草高10.0℃;冬季桔园覆盖百喜草比裸地高2.4℃,比桃园高1.1℃,夏季降温效应、冬季保温效应非常明显。桔园透光率随高度的变化呈指数关系,株间风速与株高的关系近似于二次曲线,裸地气温随高度升高而降低,百喜草和敷盖地则相反,相对湿度早晚小,中午大,夏季大于冬季;不同处理的相对湿度随高度的分布其增大、减小相间出现。
The temporal and spatial variation of light, wind speed, temperature and relative humidity of orchard covered and covered with hippophae rhamnoides were measured and analyzed. Winter at 12:00 noon when the orange orchard Taoyuan better than 2 to accompany the left and right, 14:00 when the wind speed 3 to 4 times the summer maximum ground temperature between the rows of bare grass Hippocampus 20.0 ℃ higher than the ratio of bare ground between strains The laying grass height is 10.0 ℃. In winter, the weight of the hippocampus covered with hippophae rhamnoides is 2.4 ℃ higher than that of bare land, 1.1 ℃ higher than that of Taoyuan, and the cooling effect in summer is very obvious. The relationship between the light transmittance and the plant height was similar to that of the curve of the plant height. The temperature of bare land decreased with the increase of altitude, and the opposite of the hippocampus and the cover land, the relative humidity Small, noon big, summer is greater than winter; different treatments with the distribution of the relative humidity increases, reducing the phase appears.
