摘要
在浙江省新昌县研究了香料烟生长发育过程中干物质和主要养分积累与分配规律,结果表明:‘Sam-sun’品种叶和茎、‘Canik’品种叶片干物质积累高峰期均在移栽后35～65 d,而‘Canik’品种茎干物质积累高峰期在移栽后35～80 d;‘Samsun’品种干物质在叶和茎中的分配比例分别为32.18%和53.98%,‘Canik’品种干物质在叶和茎中的分配比例分别在24.74%和58.78%。‘Samsun’对N,K,S和‘Canik’对N,P,K,Ca,Mg的吸收高峰在移栽后的35～65 d,‘Samsun’对P,Ca,Mg,Cl以及‘Canik’对S,Cl的吸收高峰在移栽后的35～80 d;整个生育期‘Samsun’对7种营养元素的吸收积累量表现为K>Ca>N>S>Cl>Mg>P,‘Canik’表现为K>N>Ca>S>Cl>Mg>P;‘Samsun’品种对K,P,Ca,Mg,S的积累量高于‘Canik’,而对N,Cl的积累量低于‘Canik’。
The accumulation and distribution rules of dry matter and main nutrients of oriental tobacco were studied in Zhejiang. The results showed that the peak period of dry matter accumulation in leaves and stem of Samsun and in leaves of Canik was during 35 - 65 days after transplanting, while that in stem of Canik was during 30 - 80 days after transplanting. Also, ＂the distribution ratio of dry matter in leaves and stem was 32. 18% and 53.98% in Samsun, and 24. 74% and 58. 78% in Canik, respectively. In addition, the absorption level of N, K and S in Samsun and the absorption level of N, P, K, Ca and Mg in Canik reached the peak during 35 - 65 days after transplanting, while the absorption level of P, Ca, Mg and Cl in Samsun and the absorption level of S and Cl in Canik reached the peak during 35 - 80 days after transplanting. Furthermore, during the growing season, the order of accumulation of major nutrients from high to low was K 〉 Ca 〉 N 〉 S 〉 Cl 〉 Mg 〉 P in Samsun, and was K 〉 N 〉 Ca 〉 S 〉 Cl 〉 Mg 〉 P in Canik. The accumulation of K, P, Ca, Mg, S in Samsun was higher than that in Canik, while the accumulation of N, Cl in Samsun was lower than that in Canik.
