【Abstract】 Polythene mulched cultivation experiments were carried out in red and yellow soil arid farmland with lower than average fertility and medium fertility level using 2 peanut varieties, Baipi No.1 and Quanhua No.10.Careful observation and sample analysis were taken in whole growth courses, and botanical characters and yield data were recorded at/after harvest. The result showed that polythene mulched cultivation enabled peanut to emerge earlier, grow faster, and resulted in a higher emergency rate. This method accelerated vegetative growth at early stage obviously, increased the number of branches per plant, enhanced leaf area index and net assimilation rate, and caused early initiation of flowering stage, more flowers, a shortened duration, higher pod weight and more pods per plant, and significant yield increases (24.1%-34.1%). This method fits to be widely extended in Southern China. Some main cultivation points were put forward in the paper.更多还原
