地膜覆盖栽培作为一项现代化的“白色”农业技术措施正在广泛普及利用。我市从1990年开始在杂交玉米制种上研究应用这项技术,几年来累计推广制种8万余亩,通过覆膜制种基本解决了种子生产成熟后降水慢,种芽易受冻害等一系列问题,并在种子产量和经济效益上也得到了一定提高。
Film mulching cultivation is widely used as a modern “white” agricultural technology measure. The city started to study and apply this technology on the hybrid corn seed production since 1990. Over the past few years, it has promoted the production of more than 80,000 acres of seed. The seed production by coating has basically solved the problem of slow precipitation after the seed is ripe and the seedling is susceptible to frost damage, etc. A series of problems, and also in the seed yield and economic benefits have also been a certain increase.
