镁素供应对雪茄烟干物质积累及镁表观利用率的影响
Effects of Magnesium Supply on Dry Matter Accumulation and Apparent Availability of Magnesium in Cigar
摘要
Abstract
Yunxue 38(Solanum variety)and Yunxue 39(Cigar core variety)were used as test materials,and three treatments were set up by hydroponics:whole vegetarian,magnesium deficiency and magnesium abundance.Agronomic characters,dry weight,magnesium content and apparent utilization rate of each treatment were determined and analyzed.The results showed that the vegetative treatment had significant effects on plant height,stem circumference,number of effective leaves,maximum leaf length and maximum leaf width.The dry weight,root shoot ratio and magnesium apparent utilization ratio were higher than those in other treatments.The root shoot ratio of magnesium deficiency treatment was the lowest.The content of magnesium in magnesium abundance treatment was the highest;the root shoot ratio showed a decreasing trend along with the progress of growth and development.Under the whole vegetable treatment,the root-shoot ratio of Yunxue 39 and Yunxue 38 was higher than that of other treatments.The agronomic traits of Yunxue 39 were higher than that of Yunxue 38.The dry weight was 3.91 g/plant and 2.24 g/plant,respectively,and the apparent utilization rate was 10.93% and 14.85%,respectively.The correlation analysis showed that dry weight was significantly positively correlated with magnesium apparent utilization rate,but not significantly correlated with application amount.Yunxue 39 was higher than Yunxue 38 in agronomic traits,dry matter content,root-shoot ratio and magnesium apparent utilization ratio.关键词
