种块大小对生姜生长及产量的影响

Effect of Seed-ginger Size on the Growth and Yield of Ginger

本试验条件下,生姜出苗期随种块的增大而提早。幼苗期,较大种块处理的植株长势较旺,但茎叶旺盛生长期后,过大或过小的种块处理都不利于生姜的生长和产量的提高。生姜产量以75 g左右的种块处理为最高,达3 572.4 kg·(667 m2)-1,而100、50、25 g种块处理的生姜产量分别为3 250.2、3 077.9、2 600.1 kg·(667 m2)-1。

The sprouting time of ginger was gradually earlier with the increasing of seed-ginger size in this experiment. The plant of big seed-ginger size grew vigorously at seedling stage. But too big or too small seed-ginger size was not beneficial to the growth and yield of ginger at vigorous growth stage. The treatment with seed-ginger size of 75 g, reached the highest yield of 238.16 kg.hm-2; while the yields of ginger with 100 g, 50 g, 25 g treatments were 216. 68 kg.hm-2, 205. 18 kg .hm-2, 173.34kg.hm-2 ,respectively.
