摘要:
为了在大田条件下研究种植密度对稻茬小麦幼苗生长状况的影响，选用冬小麦品种宁麦13为研究材料，分别于2017年和2018年采用免耕单粒精密条播方式控制稻茬小麦种植密度，设种子间距分别为1.5 cm、3.0 cm和4.5 cm 3个处理，行距均为20 cm。通过定位跟踪统计稻茬小麦出苗率和苗龄占比，同时测定分析稻茬麦幼苗个体地上部和根系指标，分别用出苗动态和单株农艺性状2类指标进行评价。结果表明，对于南方水稻土而言，稻茬小麦出苗率随着种植密度的增大而减小，但差异未达到显著水平。出苗率和苗龄占比可以用于检测不同种植密度处理之间的出苗差异。随种植密度的增加，单株稻茬小麦幼苗地上部干质量和根系干质量在2017年呈减小趋势；2018年稻茬小麦幼苗农艺性状随密度的增加而受到抑制。相比于出苗率指标，苗龄占比更能准确反映稻茬小麦的出苗密度效应。稻茬小麦群体从出苗期开始出现株间竞争，而且种植密度越大，株间竞争越剧烈。
Abstract:
To study the effects of planting density on the growth of post-paddy wheat under field conditions, Ningmai 13 was precisely sown in a single-seeded manner with seed-to-seed distance of 1.5 cm, 3.0 cm and 4.5 cm, and line spacing was 20 cm in 2017 and 2018. Seedling emergence rate and seedling age ratio of post-paddy wheat were obtained through location and tracking. At the same time, the individual shoot and root indices of post-paddy wheat seedlings were measured and analyzed, and the seedling emergence dynamics and agronomic traits of individual plant were used for evaluation. The results showed that for southern paddy soil, seedling emergence rate reduced with the increase of palnting density, but the difference did not reach a significant level. Seedling emergence rate and seedling age ratio the difference of seedling emergence among different planting density treatments for post-paddy wheat. The shoot and root dry weight of single post-paddy wheat seedling decreased with the increase of density in 2017. The agronomic characters of post-paddy wheat seedlings were inhibited with the increase of planting density in 2018. Compared with seedling emergence rate, seedling age ratio was more precise in quantifying density effects. The competition among plants began from the emergence stage. With the increase of planting density, the plant-to-plant competition becomes more and more intense.
