中国北方半干旱区机械化坐水种技术研究

Study on Irrigating-sowing with Machine in Semiarid Area of North China

机械化坐水种已成为中国半干旱区作物抗旱播种的有效措施。本文探讨了机械化坐水种的技术原理,研究了作物出苗的适宜土壤底墒,分析了2BQMS-2型坐水播种机的性能优点,提出了应用机械化坐水种技术需要解决的问题,为中国北方半干旱区发展机械化坐水种提供技术依据。

Irrigating-sowing mechanization has become an effective measure on crop drought defying sowing in the semiarid region of China. In this paper,we discussed the technique mechanism of irrigating-sowing mechanization,studied the feasible soil moisture content of crop seeding emergence in sowing period, analyzed the capabilities of irrigating-sowing machine in type 2BQMS-2,put forward technique questions which need be solved in irrigating-sowing mechanization. It provided technical base for perfecting and developing the techniques of irrigating-sowing mecbanization in the semiarid area of north China.
