Comparison of Growth Period, Yield and Value in Flue-cured Tobacco Pattern of Transplanting Young Seedlings under Film to Conventional Transplanting above Film and Its Correlation with Meteorological Factors
摘要
Abstract
In order to ensure the effect of technology of seedling transplant under plastic mulching (YSTUPM) in Baoshan tobacco-growing area and explored the meteorological foundation,a set of 10field comparison experiments that including the pattern of YSTUPM and conventional pattern above plastic mulching (CPAPM,CK) in 5 county and area of Baoshan in 2013-2014 was conducted.The results indicated that (1) The field growth period of YSTUPM were longer than that of CK,the days after transplanted (DAT) to seedling restitution,rosette,flower-bud appearing,topping,1 th picked-cured,last picked-cured,respectively longer 2.4,4.2,6.2,6.6,6.6,8.8 d.The whole growth period of YSTUPM was great significantly shorter by 16.2 d than that of CK.While the DAT to lst picked-cured,last picked-cured of YSTUPM were significantly longer than that of CK.(2) Yield,value,super leaf,middle leaf,price of YSTUPM respectively increased by 12.88％,17.61％,7.95％,3.88％ than that of CK,among of them,value of YSTUPM were significantly greater than that of CK.(3) DAT to root spreading stage was great significant positively correlation with ∑ P (T · L) root spreading (r =0.727 * *).DAT to fast growing stage was great significant negatively related to dRfast growing (r =-0.723**),∑ P (dT · dL · dR) fast growing (r =--0.764**),was significant negatively related to ∑Tfast growing (r =-0.693 *),while was great significant positively correlation with ∑Lfast growing (r =0.710 * *).DAT to maturity stage were significant positively correlation with dLmaturity (r =0.673*) and ∑ Lmaturity (r =0.675*).(4) Yield were great significant positively correlation with dTwhole growing (r =0.773 * *),∑Twhole growing (r =0.880 * *),∑P (dT · dL)whole growing (r =0.888 * *).The value were great significant positively correlation with ∑P (dT · dL) wholoe gowing (r =0.825 * *),were also significant positively correlation with ∑ P (T ·L) wholegrowing (r =0.707*),∑ Twholegrowing (r =0.880* *).Super leaf were significant positively correlation with ∑P (T · L)fast growing (r =0.629*).Middle leaf were significant negatively related to product by ∑P (T· L)fastgrowing (r =-0.653*),∑P (dT· dL · dR)wholegowing (r =-0.601 *).Price were great significant negatively related to dTwhol~owing (r =-0.926 * *),∑Twholegrowing,and also were negatively related to ∑P (dT.dL · dR)wholegrowing (r =--0.590*),∑P(T · L · R) whole growing (r =--0.666 *).YSTUPM techniques affected the whole growing duration after transplant and life duration,but also effectively updated leaf economic characters.The growth period and economical characters attribute to combined meteorological factors including air temperature (T),rainfall (R),sunshine hours (L).The information provided theory base and conference for developed and optimized YSTUPM techniques.关键词
