免耕强化栽培条件下水稻生理及群体发育的研究
Study on the Physiological Performance and Population Development of Rice under the Condition of No-tillage Intensified Cultivation
摘要
Abstract
[Objective] The study aimed to provide reference for the application of no-tillage and intensified cultivation in rice planting. [Method] With Liangyoupeijiu as tested cultivars, no-tillage rice transplanting cultivation as CK, the growth status and yield of rice under the condition of no-tillage intensified cultivation were studied through the field experiments with randomized block design. [Result] The average tiller numbers of no-tillage system of rice intensification (SRI) and CK in peak tillering period were 36.5 and 26.7 tillers/plant resp. and their difference was 36.7%; their available ear numbers in maturation period were 14.6 and 11.4 ears/plant resp. and their difference was 28.07%. In tillering, heading and maturation periods, compared with CK, the root activity of no-tillage SRI was enhanced by 17.43%, 13.63% and 22.41% resp., its proline content in leaf was enhanced by 21.37%, 32.44% and 9.92% resp. and its malonaldehyde content in leaf was enhanced by 10.42%, 13.62% and 9.47% resp. Compared with no-tillage rice transplanting cultivation, the available ear number of no-tillage SRI was reduced by 8.93% and its grain number per ear was increased by 11.32%. [Conclusion] No-tillage intensified cultivation was a high-yield and high efficient cultivation mode and it was worth popularizing and applying.关键词
