近年来我国细绿萍研究应用进展很快。细绿萍以其同氮能力强蛋白质含量高,为鸡、猪、鱼等所广泛利用的特点,既能作饲料、饵料又可间接地用作水田有机肥料。如今南方闽、浙等省有蓬勃开展稻—萍—鱼多层次、多领域的生产方式,利用稻田水面养绿萍,达到立体生态平衡,有效地解决了养地与用地之间的矛盾。关于细绿萍作为绿肥对水稻生长的影响,我组1983～1984年的研究表明:水稻在各生育期对细绿萍中氮素的利用分蘖期为14.95%、孕穗期为23%、成熟期为38.25%。至于磷的利用情况国内尚未报道。我们布置本试验目的就是为探明水稻在其
In recent years, the research and application of Fine Green Ping in China is progressing rapidly. Fine Green Lupin its nitrogen with strong protein content, for the extensive use of chicken, pig, fish and other characteristics, both for feed, food can also be used indirectly as paddy organic fertilizer. Nowadays, Fujian Province, Zhejiang Province and other provinces have flourished to carry out multi-level and multi-field production methods of paddy-ping-fish. With the use of paddy water to raise green plants, the three-dimensional ecological balance has been reached and the contradiction between raising land and land has been effectively solved. On the Green as the green manure fertilizer on the growth of rice, our group from 1983 to 1984, the study showed that: rice in the growth stages of nitrogen utilization of fine green Pingtong 14.95%, booting stage was 23%, maturity 38.25%. As for the use of phosphorus has not been reported in China. The purpose of this experiment is to identify the rice in it
