复合菌肥是一种新型的微生物肥料。它具有刺激作物生长,分解有机肥料,分解转化土壤与磷矿粉中难溶性磷、钾养分的作用。一九七二年起,由省农科院土肥所与桃源县微生物研究所及桃源县尧河公社等单位协作,开始土法生产这种菌肥,并在水稻、小麦、油菜、红薯等作物上进行多点试验。一九七三年春季早稻育秧时,又进行了一批用复合菌肥拌种催芽育秧的效果试验。一九七三年下半年,重点在尧河、八字路两公社作了近万亩连作晚稻施用复合菌肥的示范样板,并继续扩大了试验。通过两年来的试验示范证明,复合菌肥在几种主
Compound fertilizer is a new type of microbial fertilizer. It has the role of stimulating crop growth, decomposing organic fertilizers, decomposing insoluble soil into phosphate and potassium nutrients in transformed soils. Since 1972, the Soil and Fertilizer Institute of the Provincial Academy of Agricultural Sciences and Taoyuan County Institute of Microbiology and Tao Yuanxian Yao River commune and other units to start the indigenous production of this fertilizer, and rice, wheat, rape, sweet potato and other crops On the multi-point test. In the spring of 1973, when early rice seedlings were transplanted, a series of experiments were carried out to test the effect of seed germination and seedling by compound seedling fertilizer. In the second half of 1973, a demonstration model of nearly 10,000 mu of continuous compound fertilizer for continuous cropping of late rice was made in the two communes in Yaohe and Bazi Roads, and the experiment was continued. After two years of demonstration experiments show that the composite fertilizer in several kinds of master
