“冬作=玉米=水稻”栽培模式初探

“冬作＝玉米＝水稻”是以套作为中心，配套应用地膜栽培和水稻旱种的新型三熟制，在技术上可行，生产上可靠。能达到充分利用自然资源，缓解季节矛盾，省工、省力、省水、省秧田，综合效益好。该模式的关键技术是确保晚杂旱套播的一播全苗和防止草荒，促进齐苗、壮苗。

Studies on the Cropping Pattern of "Winter Crops=Corn=Rice

Winter crops=Corn=Rice" is a new cropping pattern applying a set of techniques of relay intercropping, ground plastic covering culture for corn and dryland planting for rice. The cropping pattern, technically feasible and productionally reliable, can make full use of natural resources, mitigate the contradiction of cropping seasons, save labor, water and seedling beds, which results in a good integrated efficiency. The key for this pattern is to ensure full standing of rice seeded interrow of corn and to control weeds for the growth of rice seedlings.
