摘要
着重探讨红壤丘陵区花生不同覆盖下生长状况的差别。研究结果表明不同覆盖对花生生理状况有较大影响。其中有覆盖的小区土壤含水率高于裸地 ,覆盖的小区日均土壤水分蒸发量小于裸地。
A experiment were carried out to investigate the differences in physiological characteristics in peanut plants under different mulching measures in red soil hilly area. Results show that effects of different mulching measures on physiological characteristic of peanut plant vary significantly. Soil moisture content in mulched plots were higher than those in non mulched plots, and ET rate in mulched plots is less than those in non mulched plots. The soil temperatures and peanut yields in the mulched plots were greater than those in the non mulched plots.
