chinois. 在大田栽培条件下,研究了不同摘顶时间对兰州百合植株的生长特性、鳞茎产量和品质的影响.结果表明,摘顶有利于提高百合植株的百合茎粗、叶面积、干物质总产量、鳞茎产量和商品品质;与不摘顶处理相比,现蕾初期摘顶处理的百合茎粗、叶面积、鳞茎总产量、大鳞茎鲜重和鳞茎淀粉含量分别较对照提高了20.94%、38.31%、24.52%1、4.23%和28.57%,因此现蕾初期是百合理想的摘顶日期.[著者文摘]
Afficher plus [+] Moins [-]anglais. Field experiments were carried out to investigate the effect of pinching treatment in different growth periods on growth characteristics, bulb yield and quality of Lilium davidii var. unicolor. The results showed that pinching treatment help increase the stem diameter, leaf area, total dry matter, bulb yield and quality of Lilium davidii var. unicolor. The beginning of budding was the best time for plnchlng,and compared with the treatment without plnching,the stem diameter,leaf area, bulb yield,fresh weight of big bulb and starch content of bulb after pinching treatment at the beginning of budding increased by 20.94 %,38.31%,24.52 %,14.23 % and 28.57 %,respectively.
