摘要
为获得红花高产,采用L16(45)正交试验设计,研究不同密度、氮磷钾肥和品种对红花农艺性状、产量及品质的影响。结果表明:密度对茎粗影响不显著,对百粒重、含油量影响显著,对其余性状影响极显著;氮肥对株高、含油量影响不显著,对茎粗、果球着粒数影响显著,对其余性状影响极显著;磷肥对单株及小区花瓣产量影响不显著,对株高、茎粗及含油量影响显著,对其余性状影响极显著;钾肥对株高、果球着粒数及羟基红花黄色素A影响不显著,对其余性状影响极显著;品种对所有性状影响极显著。通过各因素不同水平的综合平衡分析比较,在云南红花主产区采用12.5万株/hm^(2)的种植密度(40 cm×20 cm)、375 kg/hm^(2)的施氮量、225 kg/hm^(2)的施磷量、240 kg/hm^(2)的施钾量以及选用品种云红三号的红花生产技术模式,可达到增产增效的最佳效果。
In order to obtain high yield of safflower,an orthogonal experiment design of L16(45)was used to study the effects of different density,nitrogen,phosphorus and potassium fertilizer amount and varieties on the agronomic traits,yield and quality of safflower.The results showed that the density had no significant effect on stem diameter,but had significant effect on 100-seed weight and oil content,and had extremely significant effect on other characters.The effect of nitrogen fertilizer on plant height and oil content was not significant,but on stem diameter and seed number of fruit was significant,and on other characters was extremely significant.The effect of phosphate fertilizer on petal yield of single plant and plot was not significant,but on plant height,stem diameter and oil content was significant,and on other characters was extremely significant.The effect of potassium fertilizer on plant height,grain number and hydroxysafflor yellow A was not significant,but on other characters was extremely significant.The effect of varieties on all characters was extremely significant.Through analysis and comparison of different levels of factors,the technical model with the planting density of 12.5×104 plants/hm^(2)(40 cm×20 cm),the application of 375 kg/hm^(2) of nitrogen,225 kg/hm^(2) of phosphorus,240 kg/hm^(2) of potassium and selected variety Yunhong No.3 could reach the best effect of increasing yield and efficiency in the main safflower area of Yunnan.
