摘要
采用二因素随机区组设计方法,在山坡地栽培条件下研究了不同施钾量对兰州百合的生长以及鳞茎产量的影响.结果表明,钾素能使叶片和花蕾数增加,促进叶面积的扩展,使植株健壮,延迟叶片衰老.随着施钾量的增加,植株及鳞茎干物质的积累量呈增加的趋势,鳞茎产量在120kg.hm-2水平下达到最高.在覆膜模式下,鳞茎产量、株高、茎粗、叶片数都显著高于传统平作模式.
The impact of different levels of potassium fertilizer application on the growth and bulb yield of Lilium davidii var. unicolor was studied under cultivation condition of sidehill farmland with the random block design of two factors. The results showed that potassium fertilizer increased the numbers of leaves and flower buds, promoted enlargement of leaf area,made the plants stronger and delayed the decrepitude of the leaf. The dry matter accumulation creasing of potassium fertilizer supply. The yield of of the whole plant and big bulb were increased with in big bulb reached the highest level in potassium fertilizer supply treatment of 120 kg · hm^-2. The yield of big bulbs,the plant height,the diameter of numbers of leaves under cultivation mulched with film were sistems and the gnificantly higher than that of traditional cultivation patterns.
