辽宁省北宁市地区冬季气温一般为-20～-15℃。为保证葡萄安全越冬,秋季葡萄下架后,需在上方盖一层植被(玉米秸秆或草苫),然后在上面覆土5～10cm,传统的人工用锹覆土,效率低,劳动强度大,由于季节性强,家家都要雇人,费用较高。为解决这一难题,北宁市农机技术推广站研制成功了10OPF-A型葡萄越冬覆土机,该机是为葡萄越冬保暖在覆盖物上覆土的专用机具,适应于沙壤土和含水率12%～15%的无石块葡萄园作业。通过试验,该机多项指标均达到设计要求,于2003年7月通
The temperature in winter in Beining City, Liaoning Province is generally -20 ~ -15 ℃. To ensure the safety of grapes overwintering, the grapes need to be covered with a layer of vegetation (corn stalks or weeds) on the top of the grapes after the fall of the grapes in autumn, then the soil is covered with 5-10 cm of traditional artificial spade shovel soil, which is inefficient and labor-intensive. Seasonal, everyone should hire people, higher costs. In order to solve this problem, Beining City Agricultural Machinery Extension Station successfully developed a 10OPF-A grape overwintering shovel, the aircraft is overwintering the grapes in winter over the soil covering the special equipment to adapt to sandy loam and moisture content of 12% to 15 % Stoneless vineyard operation. Passed the test, a number of indicators of the aircraft have reached the design requirements, in July 2003 pass
