The invention discloses a base bait formula for mytilus crassitesta planktonic larva. The base bait formula comprises the following components according to the parts of a water body containing monodus subterraneus of same cell density: 65-72 parts of water body containing isochrysis galbana parke, 8-16 parts of water body containing nannochloris oculata or chlorella or a mixture of the nannochloris oculata and the chlorella, and 16-24 parts of water body containing diatom. The base bait formula has the advantages of complete nutrition, good luring property, low bait coefficient, low cost and convenience in culture.

A process for puffing the culture medium of edible fungus, which is prepared from the twigs or the straw or stalk of agricultural crops includes such steps as pulverizing, proportionally mixing it with organic and inorganic auxiliaries, puffing and baking.

The invention relates to a pholiota nameko culture method, which comprises the steps of: culture material proportioning and preparation, sterilization, inoculation and bagging, mycelium culture, summer-crossing management and primordium inducement fruiting. The pholiota nameko culture materials comprise the following recipe and mixture ratios: 30 to 50 parts of corncobs, 30 to 50 parts of soft mixed hardwood sawdust, 10 to 20 parts of bran, 2 to 4 parts of corn starch, 0.5 to 1.5 parts of gypsum and 0.5 to 1.5 parts of lime. The culture raw materials adopt the corncobs and the soft mixed hardwood sawdust as major materials, a good basis is laid for the smooth implementation of the Natural Forest Protection Projects and the pholiota nameko planting in flat areas, planting trays are omitted, the culture cost can be saved by 15 percent, the culture process is simple and is easy to implement, the work efficiency is improved, the edge fruiting effect of the pholiota nameko bag type culture is improved by 30 percent through being compared with that of the disc type culture, the edge fruiting effect of the edible fungi is sufficiently utilized, the yield can be improved by more than 10 percent, and the high-quality fruiting rate is improved by more than 40 percent.

The invention discloses a method for producing DHA and astaxanthin by mixed culturing Schizochytrium and Haematococcus pluvialls, inoculating Schizochytrium in the fermentation liquid after the growth period of Haematococcus pluvialls to carry out mixed bacterial fermentation culture , Supplement carbon source and sodium glutamate during the fermentation process, and extract oil after the cultivation is completed. The invention has the characteristics of simplifying the cultivation process, reducing the production cost, improving the stability of oil extraction and the like.

The present invention relates to a process for producing flavone through liquid-solid double-phase culture of medicinal mushroom phellinus igniarius, and belongs to the technical field of biological fermentation engineering. According to the present invention, mainly during a phellinus igniarius liquid fermentation process, a macroporous absorption resin is added to a culture liquid to establish a liquid-solid double-phase culture system so as to improve a flavone yield; with the double-phase culture process, the flavone yield can be up to 2174.35 mug / ml and is increased by 35% compared with the control; and the process has characteristics of simple operation and strong generalization, and is especially suitable for large-scale higher fungi fermentation and active substance production.

The invention provides a method for growing dendrobium seedlings, which includes in vitro inoculation of seeds, formation of circular corms through cultivation, and formation of differentiation seedlings by the cultivation of the circular corms, and is characterized by steps as follows: inoculating the differentiation seedlings on a 1 / 2 MS culture medium in a seedling raising bottle; covering with a lid; sealing the part of the lid which is connected with the bottle body with a fresh-keeping film; then placing the bottle in an ordinary greenhouse with a shading rate of 60-80% and after growing in a natural lighting environment with a temperature of 5-34 DEG and illumination intensity of 3500-9000Lx for 2 months, taking the seedlings out of the bottle and permanent-planting in a field. Theinvention can save not only the electric energy consumed in the commodity seedling culturing phase, but also the cost incurred by sterilization, sterilization medicine and manpower, and is convenientto be operated, time-saving and labor-saving. Particularly, after the culturing in the natural lighting environment, the antibacterial and disease-resistant capability of the commodity seedlings is improved, and the planting survival rate of dendrobium seedlings is greatly increased and attains over 90%.
