1983年—1985年我们在黑龙江省东宁、萝北县进行了栽培黄芪种的选择和综合栽培技术措施的初步试验。结果表明,蒙古黄芪Astragalus mogholicus鞭杆态芪产量(368.9斤/亩)远比膜荚黄芪A、membranaceus鞭杆态芪产量(83.1斤/亩)高,为获得大量鞭杆黄芪,建议栽培蒙古黄芪。根据物候观测,蒙古黄芪果熟期在7月下旬,膜荚黄芪在9月中旬,两者成熟期均较长,应适时分期采收种子。通过正交试验,看出增施尿素(6斤/亩)增产效果相当显著(p<0.01),减少中耕次数增产显著(p<0.05),是值得推广的栽培措施。
From 1983 to 1985, we conducted preliminary experiments on the selection and comprehensive cultivation techniques of cultivated yellow plant species in Dongning and Luobei counties in Heilongjiang Province. The results showed that the Astragalus mogholicus sphagnum bark production (368.9 kg/mu) was far higher than that of A. membranaceus (83.1 kg/mu). In order to obtain a large number of whip pole jaundice, Mongolian yellow sorghum was recommended for cultivation. . According to observation of phenology, the ripening period of Mongolian astragalus fruit is in late July, and that of astragalus membranaceus is in mid-September, both of which are longer in maturity, and seeds should be harvested in a timely manner. Through orthogonal test, it was found that the effect of increasing urea production (6 kg/mu) was quite significant (p<0.01), and the number of cultivating times increased significantly (p<0.05), which was worthy of promotion.
