栽培措施对全缘叶绿绒蒿种子产量和质量的影响

Impact of Cultivation Measures on Seed Quality and Yield of Meconopsis integrifolia

目的:研究栽培措施对全缘叶绿绒蒿种子产量和质量的影响,为制定其生产规程提供依据。方法:设置不同栽培密度、遮阴度、施肥方案进行小区对比试验,分别测定叶面积指数、株高、茎基粗度、果长、果径、单株结果数、结果总数、种子千粒质量、单株种子产量和单位面积种子产量,研究农艺性状、品质和产量的变化规律,分析不同栽培措施下全缘叶绿绒蒿的农艺性状变化与种子产量、质量的关系。结果:不同栽培措施对全缘叶绿绒蒿种子的农艺性状、千粒质量及产量影响较大;遮阴是全缘叶绿绒蒿大田栽培、种子生产的必要条件;有机复合肥+有效微生物群菌肥可显著提高种子千粒质量和产量。结论:筛选出的最佳栽培密度、遮阴度和施肥方案适用于全缘叶绿绒蒿的人工栽培和种子生产。

Objective:To study the effects of different cultivation measures on the seed quality and yield of Meconopsis integrifolia and provide evidence for their production procedures.Methods:Comparative experiments were conducted in different plots with different cultivation densities,shading degrees,and fertilization schemes.Leaf-area-index(LAI),plant height,stem base thickness,fruit length,fruit diameter,number of fruit per plant,total number of fruit,mass per thousand seeds,seed yield per plant,and seed yield per unit area were measured,so as to study the changes in agronomic traits,quality and yield,and analyze the relationship between changes in agronomic traits of M.integrifolia and seed quality and yield under different cultivation measures.Results:Different cultivation measures had a significant impact on the agronomic traits,mass per thousand seeds,and yield.Shading is a necessary condition for the cultivation and seed production of M.integrifolia in large fields.The application of effective micoorganisms probiotic fertilizer combined with organic fertilizer can significantly increase mass per thousand seeds and yield.Conclusion:The optimal cultivation density,shading degree,and fertilization scheme were selected,which were suitable for the artificial cultivation and the seed production of M.integrifolia.
