朝阳市处于东经118°50′14″—121°17′42″,北纬40°24′28″—42°32′36″的地理范围,属辽西丘陵地带,气候干燥,年降雨量仅500毫米左右,又集中在7、8、9三个月。春旱严重使我市地黄栽培处于出苗慢、全苗难、产量低、商品规格等级差的状态。1983年开始,我市喀左县卧虎沟乡李勤等18户药材种植户,在地黄栽培中应用了地膜覆盖新技术。提前10—15天下种,提前出苗一个月,鲜地黄亩产量增长一倍,商品规格等级显著提高。充分显示出推广应用新技术在药材生产中的巨大潜力。一、做畦、铺膜:于上年秋用犁细翻土地。3月上旬灌春水。地表干后立即平整,按南北走向做高畦,畦高10—12公分、畦面宽60
Chaoyang is located in the geographical range of 118 ° 50’14 “-121 ° 17’42” east longitude and 40 ° 24’28 “-42 ° 32’36” north latitude. It belongs to the western Liaoning hilly region with a dry climate and annual rainfall of only 500 mm Left and right, but also focused on the 7,8,9 three months. Severe spring drought in our city Rehmannia germination in slow, full seedling difficult, low yield, poor grade product specifications state. Since 1983, 18 families of medicinal herbs growers such as Li Qin in Wuhu County, Cameroon County have applied the new technology of plastic film mulching in Rehmannia glutinosa cultivation. 10-15 days in advance under the species, in advance of emergence a month, doubled the yield of fresh Huangmu, product specifications significantly improve the grade. Fully demonstrated the great potential of promoting the application of new technologies in the production of medicinal herbs. First, do 畦, film: In the autumn of last fall plowing the land. In early March irrigation water. Surface immediately after the formation of dry, according to the North-South to do high tide, high 10-12 cm, wide noodles 60
