灌溉方式和种植方式对双季稻产量和稻米品质的影响
Effect of irrigation and planting methods on the yield and quality of double-cropping rice
摘要
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 irriga-tion 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 in-creased by0.79%-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 meth-od,the milling quality of early rice and late rice with intermittent irrigation was better than that with flooding irriga-tion.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 efficien-cy,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.关键词
