摘要
2007年对不同播种期马铃薯产量的影响进行研究。结果表明,马铃薯在不同时期播种,产量差异明显。4月下旬至5月上旬,适当推迟播种期,产量增加,且以5月10日播种的产量最高,为20 987.71 kg/hm2。
Effect of planting time on the output of potato was studied in 2007. The resuhs showed that there was significant difference in yields of potato planted at different time. The yield increased as the planting time putting off between the last ten-day of April and the first ten-day of May. The highest output was 20987.71 kg·hm^-2when it was sown on May 10^th.
