| Abstract: |
| With no fertilizer as control, we studied the effect of dry matter accumulation, seed yield and quality of oilseed flax(Linum usitatissimum L.) by single application of chemical fertilizer, single application of meat protein biological organic fertilizer and different proportion of meat protein biological organic fertilizer and chemical fertilizer combined application in the field. The results are as follows: (1) Meat protein bio organic fertilizer increased plant height, stem diameter and promote the dry matter accumulation process of flax. After the bud period, the dry matter accumulation rate significantly increased under 30% meat protein biological organic fertilizer instead of chemical fertilizer (T4), being 102.33%, 55.16%, 58.68% (P<0.05) as compared to no fertilization CK (T1) at flowering stage, fruiting stage and mature stage, respectively. (2) The actual production per unit area under 30% meat protein biological organic fertilizer instead of chemical fertilizer (T4) increased by 73.66%, 17.49%, 13.74%(P<0.01) than no fertilization CK (T1), single application of chemical fertilizer (T2) and single application of meat protein bio-organic fertilizer (T3), respectively. (3) The different proportion of meat protein bio organic manure and chemical fertilizer improved the quality of flax, the oilseed flax has the best oil content under 30% meat protein biological organic fertilizer instead of chemical fertilizer (T4), The content of linoleic acid and linoleic acid is higher under 60% meat protein biological organic fertilizer instead of chemical fertilizer (T5). In conclusion, 30% meat protein biological organic fertilizer instead of chemical fertilizer should be the best treatment. |
