水葫芦原产南方,既可做饲料又可做肥料。近几年,在北京作为猪青饲料推广。由于它产量高、好管理、成本低,很受群众欢迎,推广面积日益扩大。但水葫芦不适应北方冬季的严寒气候,必须保护越冬,一般温室保种,管理时间长达6个月,花费人力物力较大。为此,我们从1974年起开展了水葫芦种子育苗的研究,经过3年的反复试验,到1976年才和基点的贫下中农一道研究成功,今年又进行了多点扩大试验,证明水葫芦能用种子繁殖。它的优点是:管理时间短,只需2个月左右;不需很多设备,能大量繁殖种苗,一克种子能育苗2,000多棵,可供4—5亩水面应用。缺点是育苗速度较慢,小苗需精心培育,花工较多。现将水葫芦种子育苗技术介绍如下。
Water hyacinth native South, can do both feed and fertilizer. In recent years, it has been promoted as a pig’s fodder in Beijing. Because of its high yield, good management, low cost, very popular with the masses, to promote the growing area. However, water hyacinth does not adapt to the cold weather in the northern winter, we must protect the winter, the general greenhouse seed, management for up to 6 months, spend more manpower and resources. For this reason, we started the research on seedling raising of water hyacinth from 1974. After three years of trial and error, we succeeded in researching with the poor and middle peasants at the base point only in 1976. This year we carried out more extended tests to prove that water hyacinth can Breeding with seeds. Its advantages are: short management time, only about 2 months; without a lot of equipment, can breed a large number of seedlings, one gram of seed can seed more than 2,000 trees for 4-5 acres of water applications. The disadvantage is the slow seedling, seedlings need to be carefully nurtured, flower workers more. Now water hyacinth seedling technology introduced below.
