摘要
免耕保护性耕作是近年发展较快的新型耕作方式,但实施多年免耕作业之后会带来土壤有效耕层变薄、容重增加、灌溉水分难以入渗等一系列问题。为此,针对免耕作业方式所出现的问题,研制开发了新型弯曲式深松犁。通过对深松犁的实地测试,对试验结果进行了研究、分析,为操作使用深松农机具提供实际参考依据。该深松犁配合免耕保护性耕作方式,充分发挥深松犁的优良性能,达到了减少水土流失和作业工序、提高经济效益的最终目标。
Conservation tillage is a new type of farming method, developed rapidly in recent years, but after years of im-plemented no tillage operation, effective soil layer became thin, soil bulk density increased, irrigation water infihered a se-ries of problems. The problem for the no tillage practice, developed the new type bending subsoiling plow. Through thefield tests of deep subsoiling plow, analysised and studied the results of the test, provided practical reference for the opera-tion subsoiling equipment. With conservation tillage mode, give full play its excellent subsoiling performance of the deepsubsoiling plows , achieve the final purpose that improve soil physical structure and crops growth condition, efficient useof natural resources, increase crop yields and economic benefits.
