摘要： The present disclosure relates to the technical field of wheat planting, and in particular to a uniform monoseeding and cultivation method of winter wheat in Huang-huai-hai region. The cultivation method includes seedbed finishing and precision seeding; after seedbed finishing during winter wheat seeding creates excellent seedbed conditions, precision monoseeding of winter wheat is implemented by a seeder according to precise agronomic index requirements including plant spacing, row spacing, seeding depth, and seeding rate, concurrently achieving the objectives of consistent covering depth and deep placement of bottom fertilizer. The cultivation method can make the most of light, heat, water, and fertilizer resources, and precisely optimize the plant spacing, row spacing, and seeding depth during seeding to integrate mechanized seeding management of winter wheat in Huang-huai-hai region, achieving objectives of building excellent crop community and increasing yield and efficiency.

摘要： The present disclosure relates to a simplified cultivation method without wheat-corn rotation system in Huang-huai-hai Plain. Aiming at making the most of regional light, temperature and water resources to increase the annual wheat-corn grain yield, the method optimally integrates cultivation technologies for two crops to achieve the objective of complementary, comprehensive and balanced annual grain production. The technical core of the method is as follows: directly planting corn with minimal tillage under no soil ploughing but straw mulching after corn harvest, and directly planting wheat with minimal tillage under no soil ploughing but straw mulching after wheat harvest, thereby realizing zero crop rotation in annual wheat-corn planting in the Huang-huai-hai Plain, making the most of light and temperature resources and increasing regional annual grain yield.
