- 摘要:
- 色素万寿菊是短日照作物，在长日照地区，常规方法栽培不能解决病害加重问题，依据生态习性在苗期进行短日照光周期调控处理，使开花提前，并延长花期，在阴雨季节，植株生长势仍保持健壮，表现抗病性强。以大花品种万寿菊为试材，采用遮光方法，研究了光照时间缩短后，对色素万寿菊生长开花的影响。结果表明：在二对真叶期每日光照8 h光照时间超过14 d，可有效避开病害发生期，实现免药耕作，提高产量效果显著。
- Abstract:
- Pigment marigold is a kind of short-daylight plant.In long-daylight areas,normal planting patterns were not suitable because of less yield and more serious diseases.Therefore,the short-daylight control was conducted during seeding period,based on the plant’s own ecological characteristics,so the blossom was advanced and florescence extended.Even during overcast and rainy seasons,pigment marigold could still grow luxuriantly and resist diseases stubbornly,the effect of light blocking on the growth and florescence of the grandflorus breed were studied.The results showed that the new method effectively avert the period of diseases and achieved no-drug cultivation during the period of two pairs of leaves,with 8 hours light per day over 14 days.
