早洋芋单产高,年商品需要量大,市场开发前景好,亩产值可达千余元。种植收获后,地块还可按时栽种大春作物,是值得重视和推广种植的一季早庄稼。洋芋(马铃薯)是以块茎为主要收获物的粮食作物,在不同的生长期对外界环境要求不同,发芽期是洋芋扎根发苗、结薯的关键时期,关系到保苗和获得高产。据资料介绍,适龄薯发芽温度为13℃,新收薯要求26～27℃温度才能发芽,土壤要求有足够的墒情,充足的氧气和适宜的温度;在幼苗期,保持土壤疏松透气,相对湿度以50～60%为宜;结薯期,晴天适温14～24℃,夜温12～17℃,即具有一定温差,土温16℃时,利于薯块膨大,短日照下成薯速度加快,保持田持水量80～85%,收获期控水以利于
Early potato yield is high, the annual demand for goods is large, the market development prospects are good, the mu output value can reach more than 1000 yuan. After planting and harvesting, the plots can also be planted with spring crops on time, which is worth as much as the promotion and planting of early season crops. Potato is a food crop that tubers are the main harvested material. It requires different environment at different growth stages. The germination period is the key period for root tuber and root tuber to be rooted, and it is related to seedling keeping and high yield. According to the information, the potato seedling temperature is 13 ℃, the new harvest potato requires 26 ~ 27 ℃ temperature to germinate, the soil requires adequate moisture content, adequate oxygen and appropriate temperature; seedling stage, to maintain soil loose breathable, relative humidity The optimum temperature is 14 ~ 24 ℃ in sunny days and 12 ~ 17 ℃ in night, which means that when the soil temperature is 16 ℃, it will enlarge the tubers and speed up the potato production under short days , Keep field hold water 80 ~ 85%, harvest water control in favor
