New Technology of Water-saving and Efficiency Production of Rice-wheat Double Cropping in Southeast Shandong Rice Region
This paper summarized the new water-saving and efficiency production technology of rice-wheat double cropping in southeast Shandong rice region from the aspects of selection and collocation of rice-wheat varieties,crop and sowing date,pre-sowing seed treatment,land preparation,sowing(transplanting)method and seed amount,fertilizer application,water management,disease,insect and grass damage control,harvest and so on.This technology is mainly aimed at the rice and wheat double-cropping grain production in Linyi City and the surrounding medium japonica-medium cropping ecological area.Compared with the traditional hand rice transplanting method,it greatly reduces labor intensity and saves manpower and material resources,and is conducive to promoting the transformation of rice planting method from traditional hand rice transplanting to dry breeding machine transplanting and machine direct sowing,with significant social,economic and ecological benefits.
