不同种植行距对干旱半干旱区荞麦农艺性状及产量的影响
Effects of Different Row Spacing on Agronomic Characters and Yields of Buckwheat in Arid and Semi-arid Regions
摘要
Abstract
In order to screen out the suitable row spacing for the arid and semi-arid buckwheat production in Baiyin City,study was carried out to investigate the influence of different row spacing on the agronomic characters and yield of buckwheat.The results showed that correlation between different row spacing treatments and agronomic traits or yield parameters of buckwheat was in descending order as plant height(r=0.774**)>number of branches(r=0.623*)>yield(r=0.358)>number of main stem nodes(r= 0.312)>thousand-grain weight(r=-0.131)>plant grain mass(r=-0.354).Different row spacing had a significant correlation with plant height,number of branches and yield.Under the seeding density of 1.2 million seeds/ha,the yield of buckwheat was the highest when the row spacing was 25 cm,i.e.,2 191.20 kg/ha which was not significantly different from those of the 20 cm and 30 cm row spacing treatments,respectively but was significantly different from that of the 15 cm row spacing treatment.关键词
