Effects of Different Soil Moisture on Leaf Major Mineral Elements and Petroleum Ether Extract at Maturing Stage
摘要
Abstract
[Objective]To study effects of different soil water on leaf major mineral elements and petroleum ether extract.[Method]A pot ex-periment was conducted to study effects of different soil water on leaf major mineral elements and petroleum ether.The soil moisture relative capacity was 40%,60%,70% and 80%.[Result]The higher the soil moisture relative capacity,the lower the potassium of tobacco.Potassi-um of middle leaves of K346 and lower leaves of Yunyan 97 most affected by soil moisture.It was found that the influence of soil moisture on P,Ca,Mg,Na,B,Zn,Cu,Fe of tobacco reached a very significant level.The correlation analysis showed the negative correlation of the content of soil moisture and Fe,P,Ca,Mg.At the soil water level of 40%and 80% of field capacity,the content of petroleum ether was relatively smal-ler.At the soil water level of 60% and 70% of field capacity,the content of petroleum ether was relatively bigger.[Conclusion]The study pro-vides a theoretical basis for the reasonable irrigation and improving the intrinsic quality of tobacco leaf.关键词
