Research on the Mathematic Model for High Yield of Flax in Yunnan Province |

| Abstract: | Flax Ariane was sown in the autumn. The relation between the stem yield and 5 main factors(planting density,the applying amount of N,P,K and the applying date of N)was studied. A mathematic model was constructed. The optimized model was density 2008 seedling/m2,urea 24.05kg/666.7m2,Ca(H2PO4)2 39.3kg/666.7m2,K2SO4 2.7kg/666.7m2. The applying dates of urea were 5% as basic fertilizer,25% when seedlings were 8-10cm high,70% when seedlings were 15-25cm high. |
