一、播前准备1.品种选择选用抗病、优质、丰产、抗逆性强、商品性好的农家红皮、农家白皮、紫花白等品种。2.切块提倡小整薯播种。使用大种薯播种时为防止浪费需要切块处理。通常在播前4～7天切块。挑选健康的较大种薯,切块大小以30～50克为宜,每个切块带1～2个芽眼。切刀每使用10分钟后或在切到病、烂薯时,用5%高锰酸钾溶液或75%酒精浸泡1～2分钟或擦洗消毒。切块后立即用含有多菌灵(约为种薯重量0.3%)的不含盐碱的植物草木灰拌种、摊晾,使伤口愈合。勿堆积过厚,以防烂种。
A preparation before sowing 1. Selection of varieties Selection of disease-resistant, high-quality, high yield, strong resistance, good commercial property of farm red skin, farm white, purple white varieties. 2. Cut to promote small whole potato sowing. The use of large seed sowing to prevent waste when cutting need to cut. Usually cut 4 to 7 days before sowing. Select a larger healthy seed, cutting the size of 30 to 50 grams is appropriate, each cut with 1 or 2 bud eyes. Cut knife every 10 minutes or when cut to sick, bad potato, with 5% potassium permanganate solution or 75% alcohol soak 1 to 2 minutes or scrub disinfection. Immediately after dicing, the plants were treated with carrageenan-free plant ash containing carbendazim (about 0.3% by weight of the seed tubers) and spread to dry the wounds. Do not accumulate too thick to prevent rotten species.
