遮阴胁迫对丹参生长及光合特性的影响
Effects of Shading Stress on the Growth and Photosynthetic Characteristics of Salvia Miltiorrhiza
摘要
Abstract
[Objective] The research aimed to study the effects of different shade on the growth and photosynthetic characteristics of Salvia miltiorrhiza.[ Method] The effects of shading stress on the growth and photosynthetic characteristics of Salvia miltiorrhiza were analyzed by measuring the main agronomic traits such as plant height, small leaf area and leaf numbers of Salvia miltiorrhiza and measured the photosyn-thetic rate in the main growth period of Salvia miltiorrhiza under different shading treatments.[ Result] Under different shading conditions, with the decrease of light intensity, the effect on the growth of Salvia miltiorrhiza was mainly manifested in the thinning of the stem, the plant height, the small leaf area and the leaf numbers increased first and then decreased .In full light conditions, too strong light was not conducive to the growth of Salvia miltiorrhiza.In July and August, the leaf area was the largest in the shade of 2.0 m ×3.0 m (when the canopy density was 32.7%) in Begonia, the leaf was well developed and the root of the medicinal organ increased, which indicated that the moderate shade was beneficial to the plant nutritional growth.[Conclusion]Shade between 32.7% of total light and canopy closure is suitable for the growth of Salvia miltiorrhiza.关键词
