摘要
如何保证亚麻正常生长和亚麻地土壤肥力稳定及养分平衡,是亚麻新产区非常关注的问题。以氮、磷、钾和几种主要微量元素进行2因素随机区组试验的结果显示,不同肥料处理组合对亚麻农艺性状的影响各不相同,对有效株数影响最大,单茎重、株高与工艺长度居其次,而茎粗所受影响最小,且大量元素对亚麻生长的影响要比微量元素更大。依据亚麻综合性状表现,配合施肥以A3B1、A2B0、A3B2、A2B2处理组合比较理想,亚麻原茎产量达到13.3t/hm2以上。在配合适量施肥前提下,亚麻地土壤肥力基本保持稳定。
It is widely concerned how to ensure vigorous growth of flax and keep stability and balance of soil nutrients in the new producing area of flax. A two-factor random block experiment was carried out , in which N,P,K were regarded as factor A and B,Mn,Cu,Zn,Mo as factor B. The results showed that the different fertilizer combination had various influence on agronomy traits of flax. The quantity of efficient plants was most signficantly influenced among the weight, height and industrial length of dry stem, while the diameter of dry stem was little affected. In addition, maeronutrients showed greater influence than micronutrients on flax growth. According to flax agronomic traits in different condition, the ideal combination of fertilization were A3B1 ,A2B0, A3B2 and A2B2,yielding more than 13.3t/hm^2 raw stem yield and keeping a good balanced soil nutrition. These results implied that soil nutrients and their balance could be preserved after production, if a comprehensive fertilizer application program was adopted.
