摘要: 以双季稻为研究对象开展小区试验,设置手工栽插、机械插秧、抛秧、直播4种种植方式与淹水灌溉和间歇灌溉2种灌溉方式,对比不同处理对双季稻全生育期水分利用效率、产量和稻米品质的影响。结果表明:相同种植方式下,间歇灌溉较淹水灌溉显著(P<0.05)降低了早稻和晚稻的耗水量,产量增加0.79%~2.94%,在相同灌溉方式下,各种植方式相比均以直播的产量最低,显著低于其他处理。相同种植方式下,间歇灌溉条件下早、晚稻的碾磨品质要优于淹水灌溉。在相同灌溉方式下,直播早稻、晚稻的整精米率显著低于其他处理。总的来看,与淹水灌溉相比,间歇灌溉能够增加早、晚稻的产量,减少耗水量,提高水分利用效率,提高稻米的碾磨品质。与移栽稻相比,直播稻的产量降低,晚稻的品质下降。综合比较,手工栽插并配合间歇灌溉的双季稻种植模式具有较好的节水、增产、优质的栽培效果。

Abstract:

In the present study, double cropping rice was selected as the study object, a field experiment was carried out with four planting methods and two irrigation methods. The four panting methods were hand-planting, mechanical transplanting, seedling throwing and direct seeding, respectively, and the two irrigation methods were flooding irrigation and intermittent irrigation. The effects of different treatments with combinations of planting method and irrigation method were compared on the water use efficiency, yield and rice quality of double cropping rice. It was shown that the water consumption of early rice and late rice under intermittent irrigation was significantly (P<0.05) decreased than that under flooding irrigation with the same planting method, yet the yield of early rice and late rice was increased by 0.79%-2.94%. With the same irrigation method, the lowest yield of both early rice and late rice was found under the direct seeding method, which was significantly lower than the others. Under the same planting method, the milling quality of early rice and late rice with intermittent irrigation was better than that with flooding irrigation. Under the same irrigation method, the head rice rate of direct seeding early rice and late rice was significantly poorer than those with other planting methods. Overall, compared with the flooding irrigation, intermittent irrigation could increase the yield of early rice and late rice, decrease the water consumption, enhance the water use efficiency, improve the milling quality of rice. Compared with transplanting, direct seeding would lower the rice yield and quality of late rice. By comparison, the combination of hand-planting with intermittent irrigation exhibited good effect on water conservation, yield increase, and high quality of double cropping rice.
