Flue-cured Tobacco " Jiucaiping2" Agronomic Characters And Supporting The Production Technology Research

The purpose of this study mainly combine with the Hezhang county’s unique geographical environment and social economic conditions, the varieties of flue-cured tobacco which suitable for Hezhang county were selected, and through the promotion of research on key cultivation technology and the newest technology, forming the characteristics of Hezhang County tobacco standardization production pattern. The results show that:1、Hezhang county is located in the sloping land which between eastern Yunnan plateau and Guizhou mountains and hills area, with an average altitude of1996m, yellow brown soil and yellow soil incurred the total land area of65.2%, the average soil pH value is6.37, the total accumulated temperature stable throughout the year with an average of4891℃, frost free period248days, the total radiation is96250kcal/square centimeter, annual sunshine1445.8hours, with hot rainy season, consistent with the conditions of the development of high quality tobacco;2、Flue-cured tobacco:Jiucaiping2tobacco, belongs to the typical sweet flavor, excellent aroma quality and the quantity is sufficient; the intrinsic chemical composition is harmonious, Taste is Elegant and pure, elegant enough oil, color thick, tissue structure loose, good maturity, easy compatibility, fill strong, sugar and nicotine is jealous; comfortable, slightly sweet aftertaste, clean, smoke and meticulous soft, local characteristics significantly, and has a broad market space and strong market competition ability; the most suitable for planting in Hezhang area;3、Flue-cured tobacco:Jiucaiping2best transplanting period between April25th-May10th, apply pure nitrogen82.5-97.5kilograms per hm2for planting density; Suitable for tobacco Jiucaiping2growth and development;4、Hezhang County in the special geographical environment and climatic conditions,15150strains (0.6m*1.1m) per hm2can well coordinate the contradiction of individual and group situations; The contradiction can better coordination of individual and group5、Application of foliar fertilizer could increase Jiucaiping2Yield and quality of tobacco, so as to further enhance thevalue and economic benefit; Penshibao is the most obvious effect in foliar fertilizer, income up to36%;...
