红薯脱毒是一项高、新、尖端的农业增产技术,生产上种植脱毒红薯苗,比种植未脱毒苗增产70％～150％。所谓红薯脱毒技术,即通过把幼嫩苗茎叶嫩生组织,进行人工脱毒培养,形成红薯脱毒原种苗,再经过扩大繁殖,形成大田栽培用苗。脱毒苗除具备常规红薯苗要求的技术特点,还要根据其脱毒苗的特点,加强田间管理,夺取高产丰收。 1 深翻土地,施足基肥 红薯是块根作物,适合生产在土层深厚,土壤疏松,通气良好的环境里。因此,在前茬作物收获后,必须深翻土地。精细整地。一般要求耕深在25～
Sweet potato detoxification is a high, new and cutting-edge agricultural production technology, production of detoxification sweet potato seedlings, than the production of non-detoxification seedlings yield 70% to 150%. The so-called sweet potato virus-free technology, that is, by tender shoots of young seedlings tissue, detoxification artificial training to form sweet potato virus-free seedlings, and then expand the breeding, the formation of field cultivation seedlings. In addition to the virus-free seedlings have the technical characteristics of conventional sweet potato seedlings, but also according to its characteristics of virus-free seedlings, strengthen field management, to seize high yield. 1 deep turn land, Shizuji sweet potato is a root crop, suitable for production in deep soil, loose soil, well-ventilated environment. Therefore, after harvesting the previous crop, the land must be slashed. Fine preparation Generally require farming depth 25 ~
