Effects of Different Planting Densities and Plastic Film Mulching on the Main Agronomic Traits and Quality of Safflower(Carthamus tinctorius L.)
探明不同种植密度及不同地膜对红花主要农艺性状及品质的影响,为干旱半干旱地区红花获得高产提供依据.以红花品种"云红七号"为试材,测定在不同种植密度(A1,8000 株•667m-2;A2,10000 株•667m-2;A3,12000 株•667m-2)及不同地膜处理(B1,黑膜;B2,透明膜;B3,不覆膜)下红花主要农艺性状及品质.结果表明:茎粗、一级有效分枝数、二级有效分枝数在A1 密度下表现最优,均显著优于A3 处理;株高、分枝高度、三级有效分枝数在A3 密度下表现最好,与其他地膜处理无显著差异;除主果球直径外,其余农艺性状在B1 地膜下表现最佳,大多显著优于B3 不覆膜处理.小区种子产量、果球着粒数、千粒重在A3 密度下达到最优,部分性状与其他密度处理有显著差异;小区种子产量、果球着粒数、千粒重、单株种子产量在B2 覆膜处理下表现最好,部分性状与其他地膜处理有显著差异;小区花瓣产量在A2B1 的互作下显著高于其他处理.不同密度与覆膜处理对红花品质无显著影响.最佳处理以产量性状为核心依据,种子主产区优选A3B2 处理;花瓣主产区优选A2B1 处理.结合"云红七号"红花的农艺性状及品质表现,在以红花花瓣为主要经济价值的云南产区,最佳种植密度及最佳覆膜方式为 10000 株•667m-2,覆黑膜.
To explore the effects of different planting densities and different plastic film mulching on the main agronomic traits and quality ofsafflower(Carthamus tinctorius L.),and to provide a theoretical basis for achieving high yield ofsafflowerin arid and semi-arid regions.Taking the safflower variety"Yunhong No.7"as the test material,the main agronomic traits and quality of safflower were determined under different planting densities(A1,8000 plants•667m-2;A2,10000plants•667m-2;A3,12000 plants•667m-2)and different plastic filmmulching treatments(B1,black plastic film;B2,transparent plastic film;B3,no film mulching).The results showed that:stem diameter,number of primary effective branches,and number of secondary effective branches performed the best under density A1,all significantly superior to treatment A3;plant height,branching height,and number of tertiary effective branches were the best under density A3,showing no significant differences from the other density treatments.Except for the diameter of the main capitulum,all other agronomic traits performed optimally under B1 plastic film mulching,most of which were significantly better than B3(no film mulching)treatment.Plot seed yield,number of seeds per capitulum,and 1000-seed weight reached the optimal level under density A3,with some traits showing significant differences from other density treatments.Plot seed yield,number of seeds per capitulum,1000-seed weight,and seed yield per plant were the best under B2 film mulching treatment,and some traits had significant differences from other plastic film treatments.Plot petal yield under the A2×B1 interaction was significantly higher than that of other treatments.Different density and film mulching treatments had no significant effect on safflower quality.Taking yield traits as the core basis for selecting the optimal treatments,A3B2 treatment is preferred in main seed-producing areas,while A2B1 treatment is preferred in main petal-producing areas.Combined with the agronomic traits and quality performance of the safflower variety"Yunhong No.7",in the Yunnan producing areas where safflower petals serve as the main economic value,the optimal planting density and film mulching method are:10000 plants•667m-2 with black plastic film mulching.
