摘要:

探讨不同种植方式对油莎豆生长发育及产量的影响,为科学栽培油莎豆提供理论依据。以‘黑油莎2号’为材料,采用二因素大田试验设计,研究了平作和垄作,以及行距30 cm、60 cm和90 cm对油莎豆生长发育及产量的影响。结果表明:(1)与平作相比,垄作降低了0~20、20~40 cm土层土壤容重,增加了土壤含水量和土壤养分含量,随行距的增大,土壤容重、土壤含水量及养分含量均减小。(2)不同种植方式下,油莎豆株高间均未达到显著差异(P>0.05),根长B1、B2和B3比A1、A2和A3分别增加了37.21%、39.24%和36.95%,分枝数分别增加了95.56%、62.09%和28.48%,叶面积分别增加了13.47%、44.23%和11.14%,根长、分枝数和叶面积在A1、A2和A3,以及B1、B2和B3之间均无显著性差异(P>0.05)。(3)B1比A1、B2比A2、B3比A3单株粒数分别增加了26.58%、7.71%和17.34%,单株产量分别增加了19.81%、18.06%和60.00%,总产量分别增加了61.21%、35.71%和9.77%。同一种植方式下,随着行距的增大,单株粒数、百粒重、单株产量和总产量均呈现先增大后减小的变化趋势。B2处理总产量最高,为7635 kg/hm2,均显著高于其他处理(P<0.05)。由此说明,垄作能改善土壤结构,增强土壤供肥能力,更有利于油莎豆幼苗生长,并且行距选择60 cm,产量最高,是较好的种植方式。

Abstract:

To investigate the effects of different planting methods on growth and yield of Cyperus esculentus, and provide a theoretical basis for scientific cultivation of Cyperus esculentus, using ‘Cyperus esculentus No.2’ as material, a two-factor field experiment design was conducted to study the effects of flat and ridge planting and row spacing of 30 cm, 60 cm and 90 cm on growth and yield of Cyperus esculentus. The results are as follows, (1) Compared with flat planting, ridge planting decreased soil bulk density in 0-20 cm and 20-40 cm soil layer, and increased soil water content and soil nutrient content. With the increase of row spacing, soil bulk density, soil water content and soil nutrient content decreased. (2) Under different planting methods, there was no significant difference of plant height (P>0.05), the root length of B1, B2 and B3 increased by 37.21%, 39.24% and 36.95% compared with that of A1, A2 and A3, respectively, the branch number increased by 95.56%, 62.09% and 28.48%, respectively, and the leaf area increased by 13.47%, 44.23% and 11.14%, respectively. There was no significant difference of root length, branch number and leaf area among A1, A2 and A3, and B1, B2 and B3 (P>0.05). (3) To compare B1 and A1, B2 and A2, and B3 and A3, the grain number per plant of the former increased by 26.58%, 7.71% and 17.34%, respectively; the grain yield per plant increased by 19.81%, 18.06% and 60.00%, and the total yield increased by 61.21%, 35.71% and 9.77%, respectively. Under the same planting method, the number of grains per plant, 100-grain weight, yield per plant and total yield increased first and then decreased with the increase of the row spacing. The total yield of B2 treatment was the highest (7635 kg/hm2), which was significantly higher than that of other treatments (P<0.05). In conclusion, ridge planting could improve soil structure, enhance soil fertilizer supply capacity, and is more conducive to the growth of Cyperus esculentus seedlings, and the row spacing of 60 cm could achieve the highest yield and is a good planting method.
