Embodiment 1

[0029] A method for raising seedlings of white and direct seeding, comprising the following steps:

[0030] (1) Arranging the seedbed: mixing the seedling-growing substrate, pesticides and nitrogen, phosphorus and potassium compound fertilizer uniformly to obtain a mixed seedling-raising substrate, the weight ratio of the seedling-raising substrate, pesticides and nitrogen, phosphorus and potassium compound fertilizer is 200:1:2, and the The mixed seedling-raising substrate is evenly laid on the field ridge, and the laying thickness is 1cm, that is, the finishing of the seedbed is completed;

[0031] (2) Treating seeds: Peel off the pods of Baiji pods to get the seeds of Baiji, mix the seeds of Baiji with raw powder, root powder and MS dry powder medium according to the volume ratio of 25:8:0.8:8 to obtain seed mixture;

[0032] (3) Sowing: Sow when the average temperature is 15°C, water the seedbed thoroughly, let it stand for 10 minutes, then sow the seed mixture to the see...

Embodiment 2

[0036] A method for raising seedlings of white and direct seeding, comprising the following steps:

[0037] (1) Arranging the seedbed: mixing the seedling-growing substrate, pesticides and nitrogen, phosphorus and potassium compound fertilizer uniformly to obtain a mixed seedling-raising substrate, the weight ratio of the seedling-raising substrate, pesticides and nitrogen, phosphorus and potassium compound fertilizer is 200:1:2, and the The mixed seedling-raising substrate is evenly laid on the field ridge, and the laying thickness is 3cm, that is, the finishing of the seedbed is completed;

[0038] (2) Treating seeds: Peel off the pods of Bletilla pods to get Bletilla seeds, mix the Bletilla seeds with raw powder, root powder and MS dry powder medium according to the volume ratio of 35:12:1.2:12, to obtain seed mixture;

[0039](3) Sowing: sow when the average temperature is 25°C, water the seedbed thoroughly, let it stand for 30 minutes, then sow the seed mixture to the se...

Embodiment 3

[0043] A method for raising seedlings of white and direct seeding, comprising the following steps:

[0044] (1) Arranging the seedbed: mixing the seedling-growing substrate, pesticides and nitrogen, phosphorus and potassium compound fertilizer uniformly to obtain a mixed seedling-raising substrate, the weight ratio of the seedling-raising substrate, pesticides and nitrogen, phosphorus and potassium compound fertilizer is 200:1:2, and the The mixed seedling-raising substrate is evenly laid on the field ridge, and the laying thickness is 2cm, that is, the finishing of the seedbed is completed;

[0045] (2) Treating seeds: Peel off the pods of Bletilla pods to get Bletilla seeds, mix the Bletilla seeds with raw powder, root powder and MS dry powder medium according to the volume ratio of 3:1:0.1:1 to obtain seed mixture;

[0046] (3) Sowing: Sow when the average temperature is 28°C, water the seedbed thoroughly, let it stand for 20 minutes, then sow the seed mixture to the seedb...

Abstract

The invention relates to a bletilla striata seed direct-seeding seedling raising method. Common seedling raising substrate, pesticides and fertilizer sold on the market are mixed, then the mixture is laid on field ridges, the laying thickness is 1-3 cm, the complex steps of producing complex substrate materials and blending substrate are omitted, meanwhile, the consumption of the substrate is greatly decreased, and the cost is saved; bletilla striata seeds, potato starch, rooting powder and an MS dry powder culture medium are mixed in a certain ratio, a seed mixture is obtained, the bletilla striata seeds are incompletely developed in nature and have no endosperms, the potatoes starch, the MS dry powder culture medium and the bletilla striata seeds are mixed to provide nutritional substances necessary for germination of the bletilla striata seeds and are equivalent to endosperms of bletilla striata, the rooting powder serves as plant exogenous hormone to stimulate rooting and germination of the bletilla striata seeds, and the germination rate of the bletilla striata seeds is increased. The method is simple to operate, raw materials are simple and available, the cost is low, the growth cycle is short, and the seed germination rate is high.

Description

technical field [0001] The invention belongs to the field of planting medicinal materials, and in particular relates to a method for raising seedlings of baiji seeds by direct direct seeding. Background technique [0002] Bletilla striata (Bletilla striata) is a commonly used Chinese herbal medicine. Bletilla striata has good astringent and hemostasis effects, detumescence and granulation promoting. Wild bacilli are becoming increasingly depleted, and they mainly rely on artificial planting to meet the market; although there are a large number of seeds in baiji, the seeds have a short life span and no nutrient reserves. The germination conditions are harsh, the seedling period is long, and they are sensitive to the environment. The seeds of baiji are very small and sterile Therefore, it is difficult to germinate and grow under natural conditions, and the cultivation of seedlings is relatively difficult. [0003] At present, most institutions and companies adopt the method o...
