品种和种植密度对红花农艺性状、产量及品质的影响
Effects of Variety and Planting Density on Agronomic Traits,Yield and Quality of Safflower
摘要
Abstract
In order to explore the effects of different varieties and planting densities on agronomic charac-ters,yield and quality of safflower,and to select the variety and density of safflower suitable for the"Weihon-ghua"area,6 safflower varieties were used in this experiment and 3 planting densities were set(D1:333 000 plants per hectare;D2:167 000 plants per hectare;D3:111 000 plants per hectare).A comparison experi-ment was conducted by using random block arrangement method,and the differences of agronomic traits,flow-er yield,seed yield and chemical constituents in flowers and seeds among treatments were measured and com-pared.The results showed that compared with the other varieties under the same density,Xinjiang Big Fruit Ball(P5)was the dominant variety with the plant height,main stem diameter,secondary branch number,bud number,bud diameter,flower and seed yield,seed oil content and seed soluble sugar content significant-ly higher.For the same variety,D2 was the most suitable planting density.With the increase of planting densi-ty,the plant height and flower and seed yield increased,while the main stem diameter,bud diameter,prima-ry and secondary branch number,bud number,and seed oil,protein,soluble sugar and starch contents de-creased.Taken these traits together,D2 density performed well among the three density treatments.To sum up,the suitable variety for planting in the"Weihonghua"area was Xinjiang Big Fruit Ball with a planting density of 167 000 plants per hectare,that was,30 cm of row spacing and 20 cm of plant spacing.关键词
