【摘要】 针对北方地区地理位置及气候的特点,干旱现象日渐突导致播种困难,提出了机械化土壤改良保墒技术并设计研发了悬挂式土壤改良保墒机械,该技术在每年秋收结束进行田间试验,播种前测试不同深度土壤含水量。结果表明,该技术不仅可以提高土壤的含水量,还可以改变由于长期使用旋耕机而导致的土壤板结问题,为保证农民实时播种、增加农民收入提供了必要的技术支持。更多还原

【Abstract】 The soil improvement and soil moisture technology by agricultural machinery were put forward, designing and making it according to the characteristics of geographical position and climate in the north, drought phenomenon is becoming more and more serious, leading to the difficulty of sowing. Annually, soil moisture is measured before sowing, experiment showing, the technology not only can increase soil moisture but also improve the problem of soi soil hardening by using rotary cultivator in the long time. Meanwhile, it provides the necessary technical support to ensure the farmers to sow seeds and to increase the income of farmers.更多还原
