Effects of Ecological Factors Variation Trend on Production Technologies of Flue-cured Tobacco in Wuyang County
摘要
Abstract
The analysis of the past five years ecological data in Wuyang showed that: during Apr. -Jun. rainfall is reduced; the monthly average temperature decreased, this period is the critical period for tobacco plant, thus affected the early development of the tobacco. The amplitude of temperature change during Jul. -Sep. is large; the inter-annual variation of sunshine hours has no law. Little change in air humidity in the past five years; strengthen the tobacco fields of water management according to the changes of the meteorological factors and take various measures to improve the tobacco fields of water and ground temperature. The analysis of soil showed that: the changes of soil nutrient are more obvious, organic matter content decreased from 1.5% (2007) to 1.26% (2010), thus affected the soil fertility level, available nitrogen has declined dramatically since 2007, the last two years it kept a considerable level. Available phosphorus content had little change. The potassium content increased. Soil nutrients spatial recovered from paid mainly organic manure and other trace elements that improved the tobacco fields of fertility to increased the quality of Luzhou-flavor tobacco.关键词
