摘要
Direct seeding has been increasingly adopted under both rainfed and irrigated conditions due to its low cost and convenience.Not only to suppress weed germination and reduce the cost of manual weeding and/or dependence on herbicides,but also to control pests and reduce pesticide usage,farmers usually flood the direct-seeded field,resulting in inadequate seed germination and seedling establishment.
