集安市地处吉林省东南部,气候条件好,很适应人参种植。但由于山高坡陡,土壤砂性大,保水能力差,出现严重缺水现象。因而,人参产量低,质量差,经济效益不佳,在人参生产没有喷灌技术前,每平方米产量仅0.65kg,产值21元/m~2。1985年通过对比试验,浇水比不浇水提高产量26％～125％。因此,自1987年以来全市开始普及应用人参喷灌技术,每年全市增产55万kg水参,增值2000万元,经济效益十分显著。具体做法是:
Located in southeastern Jilin Province, Ji’an City enjoys good climatic conditions and is suitable for planting ginseng. However, due to steep mountain slopes, sandy soil, water retention capacity is poor, serious water shortages. Thus, ginseng production is low, poor quality, poor economic efficiency, ginseng production without sprinkler technology, the yield per square meter only 0.65kg, the output value of 21 yuan / m ~ 2.1985 years through the trial, watering than not watering Increase production by 26% ~ 125%. Therefore, since the beginning of 1987, the city began to popularize the application of ginseng sprinkler irrigation technology, and the annual increase of 550,000 kg of ginseng and added value of 20 million yuan in the whole city will bring remarkable economic benefits. The specific approach is:
