“瑞奇”高效有机肥对当归产量及构成因素的研究

研究了施用新型高效有机肥料对当归根的形态﹑根重﹑产量以及麻口病害发生率的影响。结果表明：施用高效有机肥处理的鲜、干芦头径分别为3.67cm和2.57cm，较施用化肥处理增大10.54%和7.08%，鲜、干主身径分别提高7.69%、6.60%；单根干重为38.82，比化肥处理增大15.02%,平均“干/鲜” 比增加了40%；施用高效有机肥处理的成苗率提高了4.11%，干归公顷产量也高于化肥处理，达到2371.84 kg/hm2；施用高效有机肥处理的麻口病发病率为6.95%，低于施用化肥处理17.04%，有利于当归的高产、优质栽培。

study of the influence of high efficiency organic fertilizer on Chinese angelica yield effect

Compared with chemical fertilizer, the influence of high efficiency organic fertilizer on Chinese angelica root’s configuration, weight, yield and Ditylenchus destructor occurring rate was studied by field test. Conclusions were drawn as follows: By using high efficiency organic fertilizer, fresh and dry root- head diameter were 3.67cm and 2.57cm, which increased 10.54% and 7.08% than using chemical fertilizer; fresh and dry main root diameter enhanced 7.69% and 6.60% respectively; dry root weight was 38.82, which improved 15.02% than using chemical fertilizer, and D/F increased 40%; dry angelica root yield increased too, reached 2371.84 ㎏/hm2; using high efficiency organic fertilizer reduced Ditylenchus destructor occurring rate ,which was 6.95%,lower than using chemical fertilizer about 17.04%.So high efficiency organic fertilizer is helpful to get high yield and good quality on Chinese angelica.
