定西地区是当归的主要产区,年栽植面各7万亩左右,年产量650万kg以上,约占全国产量的70%和全省产量的80%。但因麻口病危害,使产量、质量受到严重影响。经过几年的试验、示范、推广,总结出优质当归丰产栽培技术:栽培当归宜选用麦类、豆类及洋芋茬,3月下旬至4月上旬选用无伤无损、生长点光亮、无侧根的健壮小苗移栽,亩保苗4000-5000株,亩施农家肥4000-5000kg,化肥纯量10kg左右,氮磷比为1:0.75-1为宜。移栽方法:以“双苗独定”法为好。为防治麻口病危害,全生育期需采取以下管 Dingxi area is the main producing area of ​​Angelica sinensis. The annual planting area is about 70,000 mu with an annual output of over 6.5 million kg, accounting for about 70% of the national output and 80% of the province's output. However, because of maize mouth disease hazards, the output and quality are seriously affected. After several years of experiments, demonstration, promotion, summed up high-quality high-yield Angelica cultivation techniques: cultivation of Angelica should use wheat, beans and potato stubble, from late March to early April to choose non-destructive, bright spots, no lateral roots Miao Miao transplanting seedlings 4000-5000 acres of seedlings, Mushi farmhouse 4000-5000kg, fertilizer about 10kg pure, nitrogen and phosphorus ratio of 1: 0.75-1 is appropriate. Transplanting methods: to “double Miao unique” method as well. In order to prevent the dangers of maikou, the whole growth period need to take the following tube
