前言:近些年由于生产方式的改变,大量连年施用化肥导致的结果是土壤有机质不断下降,土壤出现了板结、易耕性差,保肥供肥能力差、土壤不耐旱涝等不良现象。要想提高有机质的含量,需要的解决有机肥源问题,牲畜粪便资源基本枯竭,近几年大型联合收割机广泛使用,让我们找到了一种提高土壤有机质的途径——秸秆还田,我们通过几年的摸索,研究出了提高耕地质量的有效途径。1、基本情况1.1地点:项目地点设在呼兰区大用镇沈八村。
Preface: In recent years due to changes in production methods, the result of a large number of successive years of application of chemical fertilizers is the result of declining soil organic matter, soil compaction, poor plowing, poor fertilizer and fertilizer supply, the soil is not tolerant to drought and other adverse phenomena. In order to improve the content of organic matter, the problem of organic fertilizer needed to be solved and the excrement of animal manure are basically exhausted. In recent years, large-scale combine harvesters have been widely used, so that we find a way to improve soil organic matter - A few years of exploration, developed an effective way to improve the quality of arable land. 1, the basic situation 1.1 Location: The project site is located in Hurun Town, Hulan District, Shen Village.
