Flue-Cured Tobacco Floating Seedling Technology Test And Demonstration Xianyang

The main part of flue-cured tobacco production has grow seedlings, transplanting, fieldmanagement and baking grading. Seedling production of flue-cured tobacco is the first link,also decided to yield and quality of flue-cured tobacco in the key link. Breeding of newtechnology research and promotion is the broad masses of farmers and technical personnel isthe most important concern. The flue-cured tobacco floating seedling technology of tobaccoseedling is the most advanced technology. In the United States, Brazil, foreign, Zimbabweand some European countries has been widely used in tobacco production. In China, Fujian,Yunnan, Guizhou and other province area of smoke, generalize earlier development faster. Atpresent, some areas to promote the application of this technology to100%.This article through to the Xianyang flue-cured tobacco seedling technical review of thedevelopment process, summed up the past five years in the breeding technology test,demonstration and research, put forward in Xianyang tobacco-growing areas ofcomprehensive promotion of floating seedling raising techniques of technical specification,and the breeding facilities and matrix etc undertook beneficial exploration, for flue-curedtobacco seedling raising techniques in Xianyang tobacco area, large area popularizesapplication laid the foundation. Experimental demonstration of the conclusions are as follows.1, floating seedling technology to improve seedling quality and the overall level oftobacco production, compared with the conventional breeding has a clear advantage. Floatingseedling of tobacco root system developed, one or two lateral root number than conventionalseedling growth of13.7%, taproot length than that of the conventional breeding increased3cm. Floating seedling leaf area and slightly increased as compared to conventional seedlingfresh weight and blinds, shutter dry weight increased significantly, showed that dry matteraccumulation, seedling quality in seedling performance, achieves the seedling standards. Atthe same time, floating seedling root system develops, seedling rate is high, transplanted intothe field after seedling fast, water fertilizer absorption ability, drought resistance and goodperformance, performance in the transplant survival rate reached95%, compared toconventional two section type seedling90%survival rate increased5percentage points.2, labor cost is obviously reduced in floating system. Compared with the conventionalbreeding mu all labor saving2.4. Reduce the cost of104.9yuan per mu. 3, float seedling production benefit increases apparently. Floating seedling flue curedtobacco yield than the control up to13kilograms, mu production value213.57yuan higher,classy smoke scale increased by4%,3%fold increase of secondary smoke, Jin rises0.22yuan.4, since the allocation of seedling substrate adapted to the two section type floatingseedling. Raw materials can obtain raw material locally, procurement cost, only in the stackretting fermentation process into labor cost can make grow seedlings, cost is reduced. Mu cost4.23yuan.5, using a simple nursery greenhouses ensure floating seedling technology. Each shed$4257construction cost is compared32000yuan each spring and autumn greenhouse shedconstruction cost, can save the construction cost27743yuan. Simple type greenhouse shedconstruction materials to obtain raw material locally, mainly cement arch frame for easyprocessing and low cost, low cost, simple construction, durable, easy to accept the farmers.For the seedling area is relatively moderate, ensure the seedling quality, ensure the floatingseedling technology facilities need, promoted the rapid promotion of floating seedling raisingtechnique. At the same time, after the end of tobacco seedling in greenhouse, basic idle, canbe reused in the greenhouse, flowers, vegetables, and obvious economic and social benefits.
