Open type low-cost morchella seed production method based on aged wheat grains

Abstract

The invention discloses an open type low-cost morchella esculenta seed production method based on aged wheat grains, and belongs to the field of morchella esculenta planting.The method includes the steps of matrix pretreatment, matrix proportioning, strain premixing, non-woven bag cultivation and the like, raw materials include the aged wheat grains, lime, urea, activated carbon, fresh bamboo sawdust, rape seed cakes (or wheat bran) and trace elements, and the raw materials include organic matters and inorganic matters; meanwhile, a high-pressure sterilization pot and a sterile culture room are not needed, the strains are prepared in an open mode, the purpose of low-cost seed production is achieved, meanwhile, the prepared fungus bag is rich in nutrition and enough for providing appropriate nutrient substances, the phenomena of hypha aging, vigor reduction and the like of the morchella strains can be avoided, and pests can be prevented and controlled.

Description

technical field [0001] The invention relates to the technical field of Morchella cultivation, in particular to an open and low-cost seed production method for Morchella based on aged wheat grains. Background technique [0002] Morchella esculenta is a kind of edible and medicinal mushroom with rich nutrients and high economic value, which has great market demand. But the yield of wild Morchella is low, and it is difficult to collect, so in recent years, artificial cultivation technology has become an important means to supplement the output of Morchella in the Morchella planting industry, but the progress of the artificial cultivation technique of Morchella is very slow. In recent years, my country has introduced the foreign aid nutrient bag method, which has made a breakthrough in the cultivation technology of Morchella, initially solved the problem of poor stability of the cultivation of Morchella, and promoted the development of the Morchella industry. [0003] Morchella...

AI Technical Summary

Problems solved by technology

(6) Strain: the price of hickory chick strain is high, the strain culture period is long, mycelium aging is prone to occur in the transportation process, the phenomenon such as vigor reduces, seriously affects the strain quality, in addition, in the strain preparation process Need aseptic workbench, high temperature sterilization pot and other equipment, the technical threshold is high

On the one hand, this will lead to people robbing people of rations during the seed production process. On the other hand, the cost of high-quality wheat grains is relatively high. The price of morel species on the market is generally 10-15 yuan per bag (400-500g per bag), and the dosage per mu is 300 yuan. -500 packs, which greatly affects the cultivation efficiency of Morchella

Moreover, during the planting process of morels, it is also necessary to prevent common mushroom mosquitoes, mites, slugs and other pests in morels from eating the mycelia and fruiting bodies of morels, resulting in reduced yield or no harvest

Therefore, whether high-yield and stable production can be obtained in morel cultivation mainly depends on high-quality, low-cost strains, and most growers do not have large-capacity high-temperature sterilization pots and aseptic operating tables, and cannot achieve seed production. Therefore, for the above Problem, providing an open low-cost seed production method for hickory chick based on old wheat grains
