试验将种芋大小分成4个处理进行主要农艺性状、经济性状及抗性调查,结果表明:0.15kg/个处理的产量最高,达到2 760kg/667m2;随着种芋增大,生育期逐渐缩短,病害更加严重,多叶发生率越大。 The results showed that the yield of 0.15kg / treatment was the highest, reaching 2760kg / 667m2. With the increase of species, the growth period was shortened , The disease is more serious, the greater the incidence of multiple leaves.
