为适应建设高产稳产农田的需要,在研究耕地黑土肥力变化规律和总结研究群众培育高产黑土经验基础上,我们在哈尔滨院内试验地进行了培育高产黑土的试验,取得了较好的效果.现将试验结果介绍如下:一、培育途径及试验处理试验地面积7.5亩,试验采用田间大区简单对比法进行.1976年,处理区亩施草炭土约2万斤,新挖的草炭土混入少量磷矿粉堆腐4个月后施入.堆腐后的草炭土含有机质10.6%,全氮0.636%,全磷

In order to meet the need of building high-yield and stable farmland, based on the study of the law of fertility change of cultivated land black soil and the conclusion of the study of the masses’ experiences in cultivating high-yielding black soil, we have carried out the experiment of cultivating high-yielding black soil in the laboratory in Harbin and achieved good results. Test results are as follows: First, the cultivation methods and test treatment The test area of ​​7.5 acres, the test field using a simple comparison method .1976 years, handling area Mushu about 2 kg of peat soil, new dig grass peat mixed with a small amount of phosphorus After 4 months of heap deposition, the peat soil after heap compost contains 10.6% of organic matter, 0.636% of total nitrogen,
