报春花(Prinuia obconica Hance)属报春花科,为多年生宿根草本花卉。该花叶片多为长椭圆形,形同小白茶,叶丛生,花葶由根部抽出,顶生伞状花序,每花序可生出几朵至几十朵花蕾,每蕾开花一朵,多为6瓣,几十朵花拥簇逐渐而开,形成一个大的花团。其开花多为冬末、初春室外雪裹冰封之时,株形矮小,适宜盆栽,加之色彩艳丽,有的品种兼有浓郁的香味,适合室内摆放,其观赏价值较大。为了提高其观赏价值,我们坚持以实践为依据,对其栽培管理技术进行了初步探讨,总结出适于室内栽培的技术要点。1、播种技术报春花的繁殖有两种方法,播种和分根,但多以播种为主。种子多在5-6月份采收。由于其种子寿命较短,采收后应及时播种。适播期为6-9月。一般6月下旬播种的,植株发棵大,但因夏季气温高,移栽小苗成活率较低,需遮阴管理;8-9月份播种由于天气凉爽,管理方便,但生育期短,植株生长矮小,花期晚,花期也短,降低了观赏价值。一般以种子收下后播种最为适宜。播种时,先将花盆装好培养土,播种土层用细筛过筛、整平再浇透水。由于
Primula (Prinuia obconica Hance) is a Primulaceae, perennial herbaceous flowers. The flower is mostly oval leaves, the same small white tea, leaf clusters, Scape drawn from the roots, the top of the umbel, each inflorescence can produce several dozens of flower buds, buds each flowering, mostly 6 Petals, dozens of flowers gradually open clusters, forming a large flower group. Its flowering mostly at the end of the winter, early spring outdoor snow wrapped in ice, short stature, suitable for potted plants, coupled with colorful, and some varieties both rich aroma, suitable for indoor display, its ornamental value. In order to enhance its ornamental value, we insist on practice as the basis, conducted a preliminary discussion on its cultivation and management techniques, and summarized the technical points suitable for indoor cultivation. 1, sowing technology Primula propagation there are two ways, sowing and root, but mostly seeding. More seeds in May-June harvest. Due to its short seed life, timely harvesting should be harvested. Suitable sowing period of 6-9 months. Generally planted in late June, plants grow large, but due to high summer temperatures, transplanted seedlings survival rate is relatively low, shading management required; 8-9 months of seeding because of the cool weather, easy management, but the short growth period, plant growth Dwarf, late flowering, flowering is also short, reducing the ornamental value. After the seeds are generally received the most suitable sowing. Sowing, the first flower pot installed culture soil, sowing soil with fine sieve, leveling and then drenched water. due to
