1. Conditions for the growth and development of straw mushrooms
Straw mushrooms must have a temperature above 20°C, a
relative humidity above 80%, a haystack temperature of 32~38°C, and a moisture content of 70~85% of the hood in order to grow and develop normally. Therefore, it can be cultivated in the open air for three months in June, July and August, and it must be cultivated indoors in May and September to ensure the yield. For example, adding 1% ammonium sulfate or cow dung to the haystack can increase the yield. In addition to increasing the temperature of the open-air cultivation of straw mushrooms, sunlight can also promote the development of fruit bodies. This is more important for cultivating straw mushrooms in May and September, but it also has the side effects of accelerating water evaporation and burning young mushrooms. Therefore, the open-air cultivation of straw mushrooms is best under the shade of a melon shed.
2. Bacteria and cultivation site
Straw mushroom strains must choose the conditions of white hyphae, fragrance and no bacteria. Those that are blackened and deteriorated, smelly, or have yellow mold should not be used and should be eliminated. If there are clusters of small red spots on the top of the strain, it is a good strain for cultivation. A better culture material for straw mushrooms should be fresh, dried, unripe straw. The cultivation method is different due to different cultivation methods.
①Open field cultivation: If the quality of the bed soil is poor, straw mushrooms will often grow from the surroundings of the haystack and the surface of the bed soil, which directly affects the yield of straw mushrooms. Therefore, it is generally better to use loose soil, rich in humus, and more sandy loam. Sand or clay with poor water retention cannot be used as a cultivation site. Water with too high salt content is not suitable for irrigation. After the site is selected, the soil is turned up and whitened, broken up and made into a sleep. The sleeping width is 3~4 feet, the center is slightly higher, and the sides are lower, forming a turtle-back shape. The ditch is 1 foot deep and 3 feet wide. Ruler for management and harvesting. Then sprinkle hexachlorhexidine powder or spray 0.1% dichlorvos on the border to prevent pests.
②Indoor cultivation: If the cultivation bed is made of brick or gray floor, you must pick up the soil and thicken it by 4 inches to make it. If it is muddy, you must turn the soil to make a border. The method is the same as the open-air cultivation. Indoor cutting and training without borders will cause water to accumulate. At the same time, in addition to straw supplying straw mushroom nutrients, it cannot absorb nutrients from the soil, resulting in low yields.
