【Abstract】 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.更多还原
