摘要：试验比较了盆栽与大田栽培水稻的生长发育及产量情况，结果表明，在环境介质相同的条件下，大田栽培水稻平均每株分蘖数要高于盆栽水稻1倍左右。盆栽水稻成穗率要高于大田栽培水稻，盆栽水稻的平均每株成穗率为87％，大田水稻的平均每株成穗率为76％。两种栽培方式下稻谷的千粒数重无明差异，说明稻谷的千粒数重不受栽培方式的影响。盆栽水稻平均每穗实粒数99．4粒，结实率为77％；大田水稻的平均每穗实粒数151粒，结实率为85％。大田栽培水稻产量明显高于盆栽水稻，而其中的主要影响因素是两者栽培的水稻土壤状态的不同。

The growth development and yield of rice in pot and field was compared by experiment. When the environmental condition was equal, the average number of tiller per plant was 1 times higher than that of the pot. The yield of rice in pot was higher than that of field cultivation, the average spike rate of rice in pot was 87%, and in field was 76%. There is no difference of 1 000 grain weight of rice between the two cultivations, the appearance indicate that 1 000 weight grain of rice were not influenced by the cultivation method. The average grain number per panicle was 99.4 and the setting perce...
