从2007年开始连续8年呼兰区实施了测土配方施肥项目,配方施肥的大面积推广有效缓解了土壤中氮磷钾比例失调的问题,但有机质下降的的问题始终是需要解决的难题。提高土壤中有机质的含量是改造中低产田的关键,近几年我们一直探索研究改造中低产田的技术,主要研究了以下两个方面的技术措施。1秸秆还田技术秸秆还田是当今世界上普遍重视的一项培肥地力的增产措施,在杜绝了秸秆焚烧所造成的大气污染的同时还
Since 2007, Hulan District has implemented the soil testing and fertilizer project for eight consecutive years. The large-scale popularization of formula fertilizer has effectively alleviated the problem of imbalance of N, P and K in the soil. However, the problem of the decline of organic matter has always been a problem to be solved. In order to improve the content of organic matter in the soil, it is the key to rebuild mid- and low-yield fields. In recent years, we have been exploring and researching the technology of rehabilitating mid and low-yield fields, and mainly studied the following two technical measures. 1 Straw technology Field straw is a common emphasis in today’s world of a fertility fertility stimulation measures to eliminate the air pollution caused by straw burning also
