| 摘 要： | 在大田条件下,选用大穗型品种兰考矮早八号和多穗型品种豫麦49-198为试验材料,研究了不同施硫量和灌水次数对冬小麦光合性能及产量的影响.结果表明,不同施硫处理,以硫60 kg/hm2处理产量最高,并达到显著水平.兰考矮早八和豫麦49-198的增产幅度达19.32%和9.24%,此处理下的光合速率和SPAD值高于硫30 kg/hm2和硫0 kg/hm2处理.在本试验条件下,2品种在灌水处理间产量有差别,兰考矮早八以不灌水产量最高,豫麦49-198以仅拔节期灌水产量最高.

| Abstract: | Effects of different sulphur rate and irrigation time on photosynthetic characteristics and yield of two high-yield winter wheat cultivars with different spike types(LKAZ8 with a big spike and YM49-198 with a multiple spike) were studied under field experiment conditions.The results showed that the yield of the S60 with 60 kg/hm2 was higher than that of S30(30 kg/hm2) and S0(0 kg/hm2),and the differences reached a significant level between them. Compared to control(S0),the yield of LKAZ8 and YM49-198 with S... |
