【摘要】 不同留果穗数对番茄植株干物质积累量、干物质积累速度、各器官光合产物分配及产量均有不同程度的影响。留4穗果B3处理全生育期单株干物质日积累量最多5.385g,比留2穗果B1处理、留3穗果B2处理、留5穗果B4处理分别增加1.214,1.249,0.698g;果实干物质积累速度、光合产物分配率均最高,分别为3.667g·(p·d)-1和68.9%。B3处理产量也最高,每公顷产量可达58150.1kg,分别比B1,B2,B4处理增加18348.4,8693.7,11105.2kg。更多还原

【Abstract】 There are different effects on the amount and speed of dry matter accumulation,the proportion of photosynthentic product in each organ,and the yield in different remaining spikes of tomato fruits.The maximal accumulation amounts of dry matter per plant of the treatment B3in every day reach5.385g,which increase re-spectively1.214,1.249,0.698g than the treatment B1,B2and B4.The speed of dry matter accumulation and the proportion of photosynthentic product in fruits of B3reach a maximum.The yield of B3reaches5815.01kg,which increase respectively1834.84,869.37,1110.52kg than the treatment B1,B2and B4.更多还原
