Abstract:

【Objective】 To study the effects of different planting density and row spacing on the growth and yield of Carthamus tinctorius L.,Which can coordinate the growth of Carthamus tinctorius L. and significantly improve the yield of Carthamus tinctorius L. filament and seed.【Methods】 Field planting experiment was carried out in Yumin County, Tacheng Prefecture, Xinjiang from 2020 to 2021. Two-factor randomized block design was adopted, and four treatments were set for planting density: 1.0×104 plants/667m2 (A1), 1.5×104 plants/667m2 (A2), 2.0×104 plants/667m2 (A3) and 2.5×104 plants/667m2 (A4), two treatments were set for row spacing: 20 cm (B1) and 30 cm (B2). The effects of different planting densities and row spacing on the agronomic characters, dry matter accumulation and yield of Carthamus tinctorius L. were analyzed. 【Results】 The results showed that within a certain planting density range, the plant height, chlorophyll content, dry matter accumulation, yield and other indicators of Carthamus tinctorius L. gradually increased with the increase of density, while the number of fruit balls per plant, the number of seeds per fruit and the thousand-grain weight gradually decreased with the increase of density, while different row spacing had little effect on each index of Carthamus tinctorius L.. The comprehensive index and yield of Carthamus tinctorius L. under A3B1 and A3B2 treatment reached the highest level, and the filament yield under A3 treatment increased by 15.73%, 11.23% and 7.97% respectively compared with A1, A2 and A4 treatment, and the grain yield increased by 18.75%, 11.96% and 14.50%, respectively, compared with A1, A2 and A4 treatments. 【Conclusion】 Reasonable planting density (2.0×104 plants/667m2, 20 cm(B1) or 30 cm(B2) equal row spacing) is the basis of high-yield and efficient cultivation mode of Carthamus tinctorius L.

摘要:

【目的】研究不同种植密度和行距对膜下滴灌红花生长发育和产量的影响,为构建红花高光效种植模式提供参考。【方法】2020~2021年在新疆塔城地区裕民县设置田间试验,采用两因素随机区组设计,种植密度设4个处理:1.0×104株/667m2(A1)、1.5×104株/667m2(A2)、2.0×104株/667m2(A3)和2.5×104株/667m2(A4),行距设2个处理:20 cm(B1)和30 cm(B2),分析不同种植密度和行距对膜下滴灌红花农艺性状、干物质积累和产量的影响。【结果】在一定种植密度范围内,红花株高、叶绿素含量、干物质积累量、产量等指标均随种植密度的增加而逐渐增加,单株果球数、每果粒数和千粒重则随着种植密度的增加而降低,而不同行距则对红花的各指标影响较小。A3B1和A3B2处理下红花的综合指标和产量均显著优于其他处理,A3处理下花丝产量分别比A1、A2和A4处理增加了15.73%、11.23%和7.97%,籽粒产量分别比A1、A2和A4处理增加了18.75%、11.96%和14.50%。【结论】种植密度(2.0×104株/667m2(A3),20 cm(B1)或30 cm(B2),等行距)为红花高产高效的栽培模式,能协调红花生长,显著提高红花花丝和籽粒产量。
