一、选用适宜的优良品种夏地瓜生长期短,只有120天左右。因此,要求地瓜品种要具有结瓜早、膨大快、耐肥水、适应性强,无论鲜瓜和瓜干产量都较高的特点。据试验,84156、鲁薯四号、青农二号、鲁薯七号等品种鲜瓜产量差异不大,皆具有秧蔓短、结瓜早、膨大快、耐肥水、结瓜集中的特点,经几年示范推广很受群众欢迎。在有条件的地区应尽量种植脱毒地瓜R代苗,以最大限度的提高地瓜产量,增加收益。
First, the selection of suitable varieties of sweet potato growth period is short, only 120 days. Therefore, the sweet potato varieties are required to have early fruiting, swelling fast, resistant to fertilizer, adaptability, regardless of fresh melons and melons are high yield characteristics. According to the experiment, 84156, Lushu No.4, Qingnong No.2 and Lushu No.7 showed no significant difference in the yield of fresh melon, all of them had the characteristics of seedlings with short shoots, early flowering, rapid expansion, After several years of model promotion is popular with the masses. In the conditional areas should try to plant detoxification sweet potato R generation seedlings, in order to maximize the yield of sweet potato, increase revenue.
