玉米杂交是农业丰产的关键,而杂交种产量的高低及质量的好坏,直接影响到制种单位的经济效益。随着我国农业的飞速发展,玉米单产的不断提高,我国玉米制种面积不断扩大的同时,因自然灾害、环境条件及技术等造成的种子质量不合格、减产减收甚至绝收现象时有发生,给制种单位和制种农户带来严重的经济损失,大量劣质种子也给农业生产带来严重后果。针对这一问题,提出了有效的杂交玉米制种技术措施。
Maize hybridization is the key to agricultural yield, and the level of hybrid yield and quality of a direct impact on the economic benefits of seed production units. With the rapid development of agriculture in our country, the yield per hectare of maize has been continuously raised. While the area of maize planting in our country has been constantly expanding, the quality of seeds caused by natural disasters, environmental conditions and technologies has been unqualified. Which have brought serious economic losses to seed-making units and seed-producing farmers. A large number of poor-quality seeds have also brought serious consequences to agricultural production. In response to this problem, put forward an effective hybrid seed production technology measures.
