Embodiment 1

[0039] A method for field cultivation of Violet trident Dabai and tissue culture seedlings, characterized in that it comprises the following steps:

[0040] 1) Site selection: choose warm and humid, deep soil, fertile and loose, well-drained, rich in organic matter red loam, with an altitude of 1600-2500m;

[0041] 2) Soil preparation: firstly plow the selected land 30cm deep, then crush the soil, then expose it to the sun for 5 days, then apply farmyard manure until the soil organic matter content is not less than 3%, and finally cover the soil with heat-proof plastic film and carry out steam disinfection , and keep the plastic film until 2 days before planting, then remove the plastic film;

[0042] 3) Build a 30% shading net with a height of 2m on the planting plot, and set up a sprinkler irrigation system that can cover the entire planting plot at a height of 1.6m from the ground under the shading net;

[0043] 4) Seedling hardening: choose September to start hardening, i...

Abstract

The invention discloses a field cultivation method of purple-flower bletilla striata tissue culture seedlings. The method includes the following steps of 1, selecting a suitable land parcel for planting bletilla striata; 2, conducting deep ploughing and soil smashing on the selected land parcel; 3, conducting light shielding on the whole planting land parcel and erecting a sprinkling irrigation system; 4, conducting seedling hardening; 5, conducting transplanting; 6, conducting field management. According to a planting technique of the purple-flower bletilla striata tissue culture seedlings, harvesting can be achieved only within two years, and the yield per mu can reach about 2.5 tons. The suitable land parcel is selected according to environmental conditions suitable for survival of bletilla striata, and the great environmental conditions are provided for good growth of bletilla striata after bletilla striata is transplanted into the field; furthermore, by preparing the soil, alleviating soil hardening, carrying out steam sterilization to assist in plastic film mulching, killing pest eggs and weed seeds and the like, elimination of weeds at the early stage of transplanting is achieved, the situation that the growth of the seedlings is influenced since there are too many weeds during a seedling period is avoided, and the adverse impact generated on roots of the seedlings by weeding since the bletilla striata tissue culture seedlings grow slowly and the plants are small is overcome.

Description

technical field [0001] The invention belongs to the technical field of cultivating large white and in particular relates to a method for field cultivation of purple-flowered three-fork large white and its tissue cultured seedlings. Background technique [0002] The purple-flowered three-pointed big white is a species of the orchid plant Bletilla striata (Thunb.) Reichb.f., and there are other species such as yellow flowers, white flowers, and light red flowers, which are also different from the purple-flowered three-pointed small white in Yunnan. There are currently 6 species found in Baiji and 4 species in China, all of which can be used in medicine to varying degrees. However, the best medicinal materials belong to Zihua Sanchabaiji (including Zihua Sanchabaiji and Zihua Sanchaxiaobaiji). The Baiji medicinal materials listed in the 2015 edition of the Chinese Pharmacopoeia describe two conditions in detail, one is purple flowers, and the other is purple flowers. The tuber...
