本文报道了一项全新的玉米秸秆还田技术:玉米秸秆整株原位翻压还田技术(简称:整翻技术ISAGT technique)。文内介绍了整翻技术的技术工艺、操作方法和技术要点及4年的实验研究结果。研究证明,整翻处理的玉米秸杆在一年内有85％以上可以腐解,不会影响来年的秋收种麦工作;整翻处理的土壤微生物群体比清茬翻耕处理(对照)提高1～2倍;经4年整翻处理,土壤有机质含量由0.8％左右提高到1.27％,年递增约0.1％,有显著的土壤培肥效果;整翻处理对小麦苗期生长无不良影响,后期生长稳健,小麦产量逐年增加,增产幅度为5.5％～23.7％;与传统堆沤还田耕作方式和现行的粉碎还田技术比较,整翻技术每公顷作业费分别降低742.5元和225元。整翻技术具有省工、省时、省力、省钱、节能增产的良好效果,在曲周实验区不推自广,目前已有750hm~2的应用面积。
This article reports a new technology of corn stalks returning to the field: the corn stalks in situ pressing back to the field technology (referred to as: the whole turn technology ISAGT technique). The paper introduced the technical process of the whole turn technology, operation method and technical points and 4 years of experimental research results. The results showed that over 85% of corn stalks could be decomposed in one year and did not affect the work of autumn harvesting wheat in the coming year. The soil microbial population in the whole turn-over treatment increased 1 ~ 2 times. After 4 years of tipping over treatment, soil organic matter content increased from 0.8% to 1.27%, with an annual increment of about 0.1%, and significant soil fertility enhancement effect was achieved. The tipping over treatment had no adverse effects on wheat seedling growth and later growth Steady, wheat production increased year by year, the rate of increase of 5.5% ~ 23.7%; with the traditional method of plowing and plowing and returning to the field compared to the current technology, the entire turnover technology operating costs per hectare decreased by 742.5 yuan and 225 yuan. Finishing technology has the advantages of labor saving, time saving, labor saving, money saving, energy saving and yield increase. It has been applied in 750km ~ 2 in Quzhou experimental area.
