细绿萍,又叫蕨状满江红或细叶满江红。是我区新引进的水生有机肥和优质饲料。由于它固氮能力强,生长速度快,单位面积及周期产量高,有机质和粗纤维含量多,钾的含量较高,用作肥料易于分解,肥效平稳,因而是有机肥料中具有低耗(节成本,省能源)、快繁、高产、优质等特点的极有利用价值的有机肥料或饲料。我站从解决当前有机肥不足和优质青绿饲料短缺出发,通过大办样板,示范推广,养用面积逐年扩大。1980年1.28万亩,1981年5.04万亩,1982年12.69万亩。在示范推广同时,组织多点进行肥效鉴定,现简报如下: 一、养份含量云南省农科院土肥所对采自田间自然状
Fine green Ping, also known as fern-like red or fine leaves full of red river. Is my new aquatic organic fertilizer and high-quality feed. Because of its ability to fix nitrogen, fast growth, high yield per unit area and cycle, high content of organic matter and crude fiber and high content of potassium, it is easy to decompose as fertilizer and has a stable fertilizer effect. Therefore, it has the advantages of low consumption , Provincial energy), fast propagation, high yield, high quality and other characteristics of the extremely valuable organic fertilizer or feed. I stand to solve the current shortage of organic fertilizer and high quality green feed shortage starting through the big model, demonstration and promotion, raising area expanded year by year. 12,800 mu in 1980, 50,400 mu in 1981, and 126,900 mu in 1982. At the same time in the demonstration and promotion, the organization more fertilizer identification, are briefed as follows: First, the nutrient content of Yunnan Academy of Agricultural Sciences of soil and fertilizer from natural field
