Manufacturing method of exogenous nutrition bag for improving yield and quality of morchella esculenta

Abstract

According to a manufacturing method of an exogenous nutrition bag for improving the yield and quality of the morchella esculenta, the yield of the morchella esculenta measured by a test is 720 kg / 667 m<2> and is remarkably higher than that of Chinese wolfberry branch scraps, grape branch scraps and caragana microphylla branch scraps which are compared at the same time; and meanwhile, nutrient bags of the apple branch scraps are used for cultivation, and the calcium content, the zinc content and the total protein content of the mature morchella esculenta are obviously higher than those of Chinese wolfberry branch scraps, grape branch scraps and caragana microphylla branch scraps which are compared with those of the mature morchella, and are higher than the national average value of nutrient components of the morchella esculenta. The calcium content is 162.7 mg / 100g which is 1.41 times that of the caragana microphylla branch scraps, the zinc content is 17.7 mg / 100g which is 71.8% higher than that of the Chinese wolfberry branch scraps, and the total protein content is 33.5 g / 100g which is 1.27 times that of the Chinese wolfberry branch scraps; the total organic carbon content of the exogenous nutrition bag containing the apple branch chips formula is higher than that of other wood chips, and the organic carbon nutrition continuously supplied to earth surface soil is high and can be used for fruiting of morchella esculenta; and in a hypha accumulation stage, the contents of total nitrogen, alkali-hydrolyzable nitrogen and available potassium in surface soil are obviously higher than those in other branch chip formulas, and the contents of starch, total sugar and cellulose are also higher than those in other branch chip formulas.

Description

technical field [0001] The invention belongs to the technical field of hickory chick cultivation, in particular to a method for making an exogenous nutrition bag for improving the yield and quality of hickory chick. Background technique [0002] Morchella is recognized as a rare edible and medicinal large fungus second only to truffles. Because of its unique flavor and high nutritional value, it is known as the "Prince of Fungi". Consumers favor. my country is the largest country in the production and export of morel mushrooms. It has been less than 10 years since morels have been artificially cultivated, and the planting area has grown from the initial 3,000 mu to about 146,000 mu today. The cultivation area has grown from the original Sichuan-Chongqing area to all provinces across the country. The essential feature of hickory chick artificial cultivation technology is the external nutrient addition technology, that is, the external nutrition bag technology. The main fun...

Problems solved by technology

[0004] Although the cultivation of morel has made significant progress, there are still many scientific and technological problems that have not been resolved. The research on the genetic characteristics, nutritional conditions, regulation mechanism from vegetative growth to reproductive growth of morel, and the role of nutrient transformation bags, etc. It is still not in place; the specific fruiting mechanism of hickory chick is not yet clear, and the research on the direct relationship with climate, sclerotia, conidia, exogenous nutrient bags, etc. is not thorough enough. There are still major obstacles
