木薯/绿豆间套作模式下绿豆适宜播期研究

摘要

研究木薯间套作模式下绿豆适宜的播种时期,旨在为木薯间作绿豆提供科学参考.2014、2015年以绿豆品种中绿5号、桂绿豆L74号为试验材料,在木薯/绿豆间作模式下,开展绿豆的5个不同播种时期试验.2014年试验3月31日播期的绿豆子粒产量最高,中绿5号908.37 kg/hm2,桂绿豆L74号832.92 kg/hm2;2015年试验3月17日播期的绿豆子粒产量最高,中绿5号1384.56 kg/hm2,桂绿豆L74号1335.22 kg/hm2.在木薯间套作模式下,3月中旬播种中绿5号、桂绿豆L74号收获子粒产量最高,间套作效益最好,为最适宜播期.%The present experiment was conducted to study the optimum sowing time of mung bean for intercropping with cas-sava to provide references on its production. In 2014/2015,Zhonglv 5 and Guilvdou L74 were sowed at 5 different time under intercropping with cassava. The results of 2014 showed that when sown on March 31,the two varieties gave the highest yield of 908.37 kg/hm2 (Zhonglv 5) and 832.92 kg/hm2(Guilvdou L74). The results of 2015 showed that when sown on March 17, the two varieties gave the highest yield of 1384.56 kg/hm2(Zhonglv 5) and 1335.22 kg/hm2(Guilvdou L74). Under intercrop-ping condition,the optimum sowing time of Zhonglv 5 and Guilvdou L74 was the mid March. Under the optimum sowing time,mung bean had the highest yield and the best comprehensive benefit.
