节水灌溉条件下油用亚麻密度氮磷钾四因素正交旋转组合高产栽培模型研究
High-yield Planting Model of Linseed Flax Based on Orthogonal Rotation Combination Design of Density、N、 P and K under Water-saving Irrigation
摘要
Abstract
In order to optimize the irrigated farming structure in Bashang area , an orthogonal rota-tion combination with 4 influential factors was designed to study the effect of density , N, P and K on the yield of linseed flax under water -saving irrigation condition.The precipitation during the growth period after seedling was only 142.5 mm, 50%less than the common years , the test condition was extremely ar-id.In order to meet the normal growth for linseed flax , 13.3m3/666.7m2 of water were irrigated during the budding period , flowering period and grouting period.The results showed that the yield could be up to 239.7kg per 666.7m2 with the density of 668 thousand effective seeds, 12.8kg N, 7.3kg P and 6.9kg K.A planting model with water -saving, high yield and high income was put forward in the local-ity.关键词
