Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] The present invention a kind of white and direct seeding two-stage seedling raising method, and it is made up of following steps:

[0037] 1 white and small bulb formation

[0038] 1.1 Harvesting and preservation of pods. During the white and full flowering period from April to May of the current year, select plants with typical characteristics and strong growth for artificial pollination. Harvest when the fruit pods are mature from August to October, dry the surface water, and use clean toilet paper for every 8 to 10 fruit pods...

Abstract

The invention discloses a bletilla seed direct-seeding two-stage seedling culture method. The method is characterized by including two different stages, namely bulblet forming and bulblet graded broadcast sowing, and graded culture is performed on seed seedlings for two times, so that the phenomenon that big, small and medium seedlings are mixed in conventional seed direct-seeding seedling culture is overcome effectively, and seed seedling orderliness and field uniformity after transplanting are improved. The method can be completed by a producer alone and can be undertaken by different producers, thereby being conducive to developing standard production of seed seedlings; no plant growth regulator is added in the culture process, so that aberration rate is lowered effectively; seed seedling production is high in yield and efficiency, more than 500 thousand plants can be produced per mu in each period, it only takes 9-10 months normally from seed broadcast sowing to field transplanting, and field orderliness is improved by 70%, and yield is increased by higher than 18%.

Description

technical field [0001] The invention belongs to the technical field of seedling propagation of traditional Chinese medicinal materials, and in particular relates to a two-stage seedling raising method for live-sowing seeds of bletilla. Background technique [0002] White and [Bletilla striata (Thunb.) Reichb.f.] is a perennial herb belonging to Orchidaceae white and is one of the important Chinese medicinal materials, and its medicinal part is its dry tuber. Its taste is bitter, sweet, astringent, and slightly cold in nature; it returns to the lung, liver, and stomach meridians, and has the functions of astringent and hemostasis, detumescence and granulation promoting. In addition to the pharmaceutical field, Baiji is also widely used in food, tobacco, chemical, flower and other industries. The distribution area of ​​white and white is relatively wide, but the resource of white and white is very short in our country, has become the bottleneck restricting the sustainable dev...
