水葫芦,又名水绣花、凤眼莲,是多年生草本植物,富含蛋白质、脂肪、纤维素和钙、磷等无机盐类,是养猪的好饲料。它在气温7—10℃以上才能安全越冬,13℃左右才能增株繁殖。水葫芦引种我省已有十几年,但由于越冬保种技术没过关,推广不快。近年来有的采取温室保种,虽能越冬,但费钱费煤,成本高。因此,我们根据蔬菜冬季温床育苗和甘薯温床育苗的原理,同时又考虑到水葫芦喜温好湿的特点,采取“温床盆养”,取得成功。具体作法大体同蔬菜、甘薯温床育苗的做法基本相似。在背风向阳的地方,挖
Water hyacinth, also known as water embroidery, Eichhornia crassipes, is a perennial herb, rich in protein, fat, cellulose and calcium, phosphorus and other inorganic salts, is a good feed for pigs. It is above the temperature of 7-10 ℃ in order to be safe winter, about 13 ℃ in order to increase strains. Introduction of water hyacinth in our province for more than 10 years, but because of over-winter seedling technology no clearance, promotion of unpleasant. In recent years, some adopt greenhouse seed-saving, although the winter, but the cost of coal, high cost. Therefore, based on the principles of vegetable seedling raising in winter and seedling growing in sweetbush seedling, and taking into account the characteristics of water hyacinth and good warm and wet, we adopted “hotbed pot raising” to achieve success. The specific approach with vegetables, sweet potato hotbed nursery practice is similar. In leeward sunny place, dig
