摘要: 为探讨在闽西北气候条件下,木薯套种大豆的最适播期,研究播期对大豆和木薯产量、农艺性状和经济效益的影响。结果表明:大豆套种木薯条件下,大豆3 月17 日播种,大豆和木薯的产量最高,分别为1432.5 kg/hm2和20511.0 kg/hm2,纯收入最高,达2350.50 元/hm2。因此,大豆3 月中旬播种,大豆和木薯的产量越高,农艺性状越好,产值越高。

Abstract: For the purpose of the optimum dates, the effect of soybean different sowing dates under soybean intercropping with cassava on yield, agronomic characters and economic benefits of soybean and cassava in northwest of Fujian Province were studied. The results showed that in the models of cassava intercropped soybean, when the soybean were sown on the date of March 17, the highest yield of soybean and cassava were 1432.5 kg/hm2 and 20511.0 kg/hm2 respectively, and the highest net income was 2350.50 yuan/hm2. Under growing time of cassava, earlier planting soybean was both good for higher yield, main agronomic characters and net income. The optimum dates of soybean sowing was days in mid March.
