叶面肥喷施对汉麻叶面积及干物质积累分配的影响

Effects of Foliar Fertilizer Spraying on Leaf Area and Dry Matter Accumulation and Distribution of Industrial Hemp

为了明确叶面肥对纤维汉麻的影响,以火麻一号为试验材料,研究了叶面肥喷施后汉麻叶面积和干物质积累与分配的变化。结果表明,喷施叶面肥后能够提高汉麻的叶面积,促进汉麻叶片的生长发育,延缓衰老;喷施叶面肥后提高了汉麻单株、叶片、秆芯、麻皮、根系的干物质积累量及麻皮产量,增加了叶干重所占比例和麻皮干重所占比例,降低了秆芯干重所占比例;自制汉麻专用叶面肥(F2)的效果明显优于磷酸二氢钾叶面肥(F1)。该研究为汉麻高产栽培技术和汉麻叶面肥的推广应用奠定了理论基础。

In order to clarify the effect of foliar fertilizer on fiber hemp, Huoma No.1 was used as experimental material to study the changes of leaf area, dry matter accumulation and distribution of hemp after spraying foliar fertilizer. The results showed that spraying foliar fertilizer could increase the leaf area, promote the growth and development of leaves and delay aging. Spraying foliar fertilizer increased hemp bast yield and the dry matter accumulation of per plant, leaf, stem core, hemp bast, root. And it increased the proportion of leaf dry weight and bast dry weight, while decreased the proportion of stem core dry weight. The effect of self-made special foliar fertilizer for hemp(F2) was significantly better than that of potassium dihydrogen phosphate(F1). This study laid a theoretical foundation for the high-yield cultivation technology of hemp and the popularization and application of hemp foliar fertilizer.
