细绿萍起繁点低、繁殖快、肥效高、适应性广,是有发展前途的水生绿肥和饲料植物。但由于夏季气温过高,病虫猖獗,细绿萍常成片死亡而难以保种。所以许多单位除进行细绿萍的营养体越夏试验外,并先后开展了利用细绿萍孢子果越夏的研究。初春二月,细绿萍的孢子果已开始发生,5—6月即可逐渐或熟。我们在这里把细绿萍孢子果的采收和育苗方法作一综合介绍,以供试验时参考。 Fine Green Ping played less complex, fast propagation, high efficiency, wide adaptability, there is a promising aquatic green manure and feed plants. However, as the summer temperatures are too high, pests and diseases rampant, thin green leaf often become a piece of death and difficult to maintain seed. Therefore, many units in addition to fine green Ping nutrition body more summer test, and has carried out the use of fine green spore fruit summer research. Early spring in February, fine green Ping spore fruit has begun to occur, 5-6 months can be gradually or cooked. Here we put Sphaerotheca fine harvest and breeding methods for a comprehensive introduction for the test reference.
