What are the main strains of cultured letinous edodes?
Mushroom canopy structure in most plain areas of North China, the average temperature in winter in January was -3 to -10 C, and the initial frost was in late October. The autumn letinous edodes mushroom season generally after October, at this time, more cold north wind, windy, low temperature, dry air, is not conducive to mushroom. Therefore, the North should adopt the semi underground type sunlight greenhouse. The shed is usually made of bamboo and wood, with east-west width of 10 meters, 30 meters long, and a floor area of 300 square meters. Below ground level dig deep 0.5 meters, south wall slightly higher than the ground, along the wall to do 0.1 meters wide drainage ditch, and shed outside the seepage well interlinked. For some mainland shed slightly to the root of the south slope, wall drainage. The north wall is 2 meters high and leaves a 0.4 meter x 0.25 meter window above 3.25 meters above the ground. Keep along the north wall for 1.3 meters wide. Something to hang 3 root powder pipe, pipe between the distance of 2.5 meters, 1.6 meters in height, in the bulk water pipe every 1 meters to install a dedicated spray head.
Select varieties of northern spring cultivation, should select moderate, medium temperature, high strains, such as Cr04, L26, min 3, Cr66 and so on. Autumn planting should choose medium temperature low type letinous edodes strains, such as Min Hao 5, Cr62, with medium temperature type L26, Min Hao 1 strain, etc.. What is worth mentioning is that the old variety Cr02 has the characteristics of not turning color and fruiting, early fruiting, quick turnover, high yield and low temperature resistance. The disadvantage is that a mushroom and mushroom shaped small cap, thin, suitable for fresh market sales and production of Cr04, Cr62 and L26 cans; mushroom shaped large and round, single mushroom, good color, high quality, suitable for export fresh flesh, or dry mushroom. For the effective use of the natural temperature, should choose early or middle maturing varieties, such as late maturing varieties, fungus mushroom mature period is too long, prone to impatience, relaxed management, often leads to failure of cultivation.
Timely sowing according to the climatic characteristics of the temperature requirements of letinous edodes at different growth stages and the North was confirmed, the purpose is to turn color and hair fungus, mushroom three stages of control under the suitable conditions, to ensure the high quality of letinous edodes, has high market efficiency. In the north of the Great Wall area such as Chengde, Zhangjiakou and other places, the climate is characterized by winter cold, summer is cool and can be planted in the spring, in the selection of varieties, high temperature, from 2 to March with low temperature bacteria, letinous edodes robust mycelium bacteria contamination rate is very low. In June, the mycelium was mature and turned out to be mushroom at the right time. 7~9 months coincided with the production of letinous edodes in the southern part of the country. However, the fresh letinous edodes supplied the domestic and overseas markets and made a lot of profit. Letinous edodes of North China plain area cultivation, can be planted in autumn, the temperature variety, in August with natural temperature strain, October turned edge of fruiting, year long autumn mushroom. Winter preservation of bacteria, spring to continue to grow mushrooms, there is a long fruiting period, higher yield.
The mushroom shed a mushroom bed three layer 12. The mushroom bed is 1.05 meters high, and the ground floor is 0.35 meters apart from the ground and between the layers. The vertical bed is provided with a pair of upright posts at intervals of 2 meters. The column is fixed with a cross bar, and a bamboo sheet is arranged on the cross bar, and the gap between the bamboo pieces is 2.8 centimeters. Mushroom bed 8 meters long, 1.4 meters wide, a floor area of 11.2 square meters, a bedstead, three layers of mushroom beds, with a total area of 33.6 square meters.If Japanese mushroom bags are used, the bags are 32 cm x 20 cm and 1 kg wet material. The mushroom bag removal to each other at a certain distance, an average of 1 square meters of mushroom bed 36 bags. The number of bacteria of 300 square meters are as follows: 36 Gupeng square metres x 12 x 33.6 bags =14500 bags; if the area is under construction, per square metre mushroom shed: 14500 bags, 300 square meters =48 square meters / bag. If the Fujian Gutian style slender rod bacteria, bag size is 55 cm x 15 cm, with 2 kilograms of wet material, the mushroom shed ground on oblique rod vertical, 667 square meters (1 acres) mushroom shed can be placed 8000 rods, the average per square metre 12 bar. Such as the use of high shed to take 5-6 layers of mushroom beds, bacteria stick flat, remove the channel covers an area of 1 acres of mushroom shed can be placed 20000 bars, an average of 30 meters per square meter.
