一、选用脱毒种薯在定陶县种植表现较好的早熟品种有荷兰15、鲁引1号、东农303等品种。荷兰15、鲁引1号从荷兰引进,出苗到收获60～70天。株高60cm左右,茎秆粗壮,分枝少,叶片肥大,块茎膨大快,结薯集中,薯块椭圆形,产量高,一般666.7m~2(亩)产2000～3000kg。二、搞好种薯催芽处理为使马铃薯播后尽快出苗,必须播前20～25天进行催芽处理,经过处理的种薯,一般早出苗10～15天,增产25%左右。 (一)切块催芽前将种薯切块,切块大小以25g左右为宜,每个切块至少在种薯中上部有一个已萌动的芽眼。切后在阴凉处摊晾1h(小时)左右,使切面水分自然蒸发。
First, the use of virus-free seed potato planting in Dingtao better performing varieties of the Netherlands 15, Lu cited No. 1, Dongnong 303 and other varieties. Netherlands 15, Lu cited 1 imported from the Netherlands, emergence to harvest 60 to 70 days. Plant height of about 60cm, stalks stout, less branches, leaf hypertrophy, tuber expansion fast, concentrated tuber, potato oval, high yield, generally 666.7m ~ 2 (mu) production 2000 ~ 3000kg. Second, improve seed germination treatment In order to make potato as soon as possible after sowing, must be sowing 20 to 25 days before germination treatment, after treatment of seed, generally early emergence of 10 to 15 days, an increase of 25%. (A) cut before germination will seed cut into pieces, cutting the size to 25g or so, each cut at least in the upper part of the seed has been sprouting bud eyes. After the cut in the shade of air drying 1h (hours), so that the natural moisture section.
