| Abstract: |
| In order to study the effect of different sowing date and late-sowing with straw mulch on dry matter accumulation and yield compoeition of tomato for proeessing, a field experiment was eonducted on Shihezi University(86°01'E,44°26'N)during 2009-2010. In the study, four sowing dates(Apr.10,Apr.25, May 10 and May 20)and latesowing straw mulch(May 10F+J;May 20F+J)treatments were conducted in field. The tomato cultivar ‘Liger 87-5’was selected to plant. The results showed that the sowing date and straw mulching had significant effect on the dry matter accumulation and yield of transplanted and directly-seeded tomato. The dry matter accumulation and yield had a significant tendency of gradually decreasing with the delay of sowing time. The highest yield per plant of transplanted and directly-seeded tomato in this experiment appeared in the tomato sown on Apr.24, its yield could be 4498.2 g/plant and 3955.9g/plant, significantly higher than that sown on other days. In yield composition factors, sowing date had significant influence on the number of valid fruit of individual plant but had not significant influence on the average weight per fruit. The treatment ol late-sowing with straw mulching had significant effect on plant growth compared with no straw mulching on the same sowing date. The dry matter accumulation of transplanted plants increased by 15.5% and 9.6%, the yield of transplanted plant inereased by 36% and 39.8%. The dry matter accumulation of directly sown plants in-creased by 27.8% and 15.7%, while the yield of direetly sown plants increased by 12.2% and 9%. The average weight per fruit of transplanted plants increased significantly by using straw mulching and that of directly-sown ones re-mained the same or decreased slightly. |
