工业大麻品种“云麻1号”籽、秆高产栽培模型研究

Model of High-yielding Cultural Measures for Seed and Stem Compatible Type of Yunma No.1

应用二次回归正交旋转组合试验设计法,对工业大麻品种云麻1号的栽培密度及氮、磷、钾肥用量4个关键农艺措施与籽产量和秆产量的关系进行研究,分别建立了2个数学模型,并对回归模型进行失拟性和显著性检验,证明2个模型皆与实际拟合较好,可靠程度较高。优选出同时获得籽产量1500 kg/hm2、秆产量12 750 kg/hm2的兼用型栽培措施为：行距76.16-83.84 cm,施氮（N）量为80.85-83.82 kg/hm2,施磷（P2O5）量为33.32-41.68 kg/hm2,施钾（K2O）量为54.24-65.76 kg/hm2。

The quadratic regression orthogonal rotational combining design,four key comprehension cultural measures on the seed and stem yields of industrial hemp variety Yunma No.1 was studied,such as the planting density,nitrogen （N）,phosphorus（P） and potassium（K） fertilizer rates.Two corresponding mathematic models were established respectively.Each of the models agreed well with the practice and was highly reliable by testing lose effectiveness of fit and significant test.The optimized seed and stem compatible type of cultivation measure was the raw space of 76.16-83.84 cm,nitrogen rate of 80.85-83.82 kg/hm2,phosphorus（P2O5） application amount of 33.32-41.68 kg/ hm2 and potassium（K2O） of 54.24-65.76 kg/ hm2.Using the optimized measure,the seed and stem yield could reach 1500 and 12 750 kg/hm2 simultaneously.
