搞好种子生产,为农业提供优质种子,对增产粮食是至关重要的。要获得高产优质的种子,也需要遵照气象条件的基本规律。我省是国家的玉米种子生产基地,每年供应全国玉米种子2.5亿kg,约占需种总数量的1/3。这里就搞好玉米种子生产与气象因素的关系谈几点看法。 1 热量与种子生产。玉米是喜温作物,生育期要求较高的温度条件。一般中熟种需要≥10℃的积温2600～
Improving seed production and providing high-quality seeds for agriculture are crucial for boosting grain output. To get high-yielding and high-quality seeds, we also need to follow the basic rules of meteorological conditions. Our province is the country’s corn seed production base, the annual supply of corn seed 250 million kg, accounting for about 1/3 the total number of species. Here to improve the relationship between corn seed production and weather factors talk about a few points. 1 heat and seed production. Corn is a thermophilic crop, the higher the temperature requirements of the growing period. Generally cooked in ≥10 ℃ accumulated temperature 2600 ~
