Abstract:

To study the effects of density and reserved leaf number on the growth duration, agronomic character, yield and output value, the test was conducted on the density (Ai): (16665, 13875 and 11895 plants/hm2, respectively) and reserved leaf number (Bj): (26, 22 and 18 pieces, respectively) for planting tobacco in cold waterlogged paddy field. The results showed that: (1) the density has certain effect on the growth duration. The budding period of low density is 1.7-2 days earlier than high density; (2) In the mature period, correlative analysis showed that there was a significant positive correlation between density and plant height (r31 = 0.9992, p<0.01 and there were negative correlation between density and stem girth, total leaf number and maximum leaf area, but not reach significant level; (3) The results showed that there is a positive correlation between density and yield (r31 = 0.9318), but the highest output value was the one whose density was 925 plants/667 m2; (4) Correlative analysis showed that there is a significant positive correlation between reserved leaf number and yield and output value (r81 = 0.9985, p<0.01, r82 = 0.9851, p<0.05); (5) The first five leading yield is A1 B1, A2B1, A1B2, A1B 3, A2B2 The first five leading output value is A2B2, A2B1, A1 B1, A1B 3, A2B 3; (6) Analysis of output value and economic traits of tobacco result showed that the best combination of planting tobacco in cold waterlogged paddy field was 13875 plants/hm2 with 22 pieces/plant.
