Cultivation Season and Spawn Selection Methods for Straw Mushrooms
I. Cultivation Season The optimum temperature for the mycelial growth of straw mushrooms is 30°C-35°C, and the optimum temperature for fruiting body growth is 28°C-30°C. It takes more than 1 month from stacking the substrate to the end of fruiting. Among the currently artificially cultivated edible fungi, it is the mushroom type with the higher temperature requirement and the shortest growth cycle. An appropriate cultivation period can be chosen according to the temperature requirements of straw mushrooms and the different cultivation conditions in each region. II. Spawn Selection It is very important to select high-quality, high-yield varieties according to local conditions and actual circumstances. The criteria for variety selection are high yield, good quality, and strong stress resistance.

Preparation method of secondary spawn and production spawn of straw mushroom
Secondary spawn is the spawn made by transferring primary spawn into secondary spawn substrate. Secondary spawn can be used directly as production spawn. Generally, secondary spawn is transferred to the same kind of substrate for expanded culture to become production spawn. Secondary spawn is generally placed in 750 ml mushroom bottles or plastic bags. (1) Preparation of substrate. Formula 1: rice straw 90%, bran (rice bran) 9%, gypsum powder 1%. The preparation method is to select golden-yellow, non-moldy dry rice straw, cut it into 3 cm lengths, soak it in clean water for about 12 hours to

Dried Straw Mushrooms
After straw mushrooms are harvested, their growth does not stop, and the caps will continue to elongate. Therefore, besides being eaten fresh, they must be processed quickly into dried straw mushrooms or canned straw mushrooms, etc. Before processing, the soil and rotting grass at the base of the young mushroom buds (mushroom bodies) should be removed with a small knife, and they should be graded according to commercial standards. Those sold far away should also be packed in plastic bags and transported under refrigeration in a refrigerator or cooler box to preserve the quality of the fresh mushrooms. For processing into canned straw mushrooms, Grade 1-2 fresh mushrooms are best; although Grade 3-4 fresh mushrooms can be sliced into sliced mushrooms, their quality is inferior. For processing into dried straw mushrooms, it is best

Detailed Explanation of New High-Yield and High-Efficiency Cultivation Techniques for Straw Mushroom
Straw mushroom, also known as orchid mushroom, delicious bract-foot mushroom, Chinese mushroom, and Nanhua mushroom. It is a thermophilic and hygrophilic straw-textured saprophytic fungus that grows in summer on grasses such as rice straw and other Gramineae grasses, or on fibrous waste such as cotton and hemp. Straw mushroom is delicious, nutritious, and has good health-care effects. It is cold in nature and sweet in taste, has the function of relieving summer heat and removing fever, and has effects such as strengthening the body and bones, protecting the liver and strengthening the stomach, promoting lactation, and detoxifying. Eating straw mushroom regularly can increase the body's resistance and accelerate wound healing. It can also reduce cholesterol accumulation and lower blood pressure. Therefore, straw mushroom has always been favored by consumers

Detailed Explanation of Key Points for High-Yield Cultivation Techniques of Straw Mushroom
1. Selecting good spawn is key. It is best to use a newly bred first-generation improved variety; varieties that have been subcultured too many times are prone to quality degeneration and yield decline. At the same time, avoid mixed cultivation of different types of straw mushroom spawn. 2. Properly handle the growing substrate. The main growing substrate for cultivating straw mushroom is rice straw. To improve the quality of the growing substrate, when the rice straw is spread out to dry, it can be beaten with sticks or rolled with stone rollers, pressing it repeatedly to make the rice straw fine, loose, soft, and easy to absorb enough water, so that it can be pressed more firmly when building the bed, which is beneficial to fermentation. The rice straw is soaked in water. pile-fermented, and 1% lime

Detailed Explanation of High-Efficiency Cultivation Techniques for Straw Mushroom, Lecture 3
Straw Mushroom Bed Cultivation Techniques Straw mushroom shelf-bed cultivation is currently a commonly used cultivation method. Building shelves inside a house or shed not only makes full use of space and improves utilization, but also provides good moisture retention and insulation, is easy to manage, and gives high and stable yields. 1. Mushroom House Setup 1.1 Dedicated Mushroom House: For cultivating straw mushrooms, a dedicated straw mushroom house can be built. This mushroom house is suitable for year-round production. The mushroom house is 3-4m long, 2m wide, and 2.5m high. The four walls are lined with 1-2cm thick foam plastic boards,

Detailed Explanation of High-Yield Cultivation Techniques for Autumn Potatoes with Rice Straw Mulching
Potatoes have the characteristic of preferring cool conditions and fearing heat, making them perfectly suited for no-till planting in idle winter fields. This method requires no plowing or soil covering, saving labor and effort, and is simple to operate. Harvest can be achieved after 3 months, with an average yield of over 1,500 kg per 667 sq m, a 30% increase compared to traditional cultivation methods. At 0.8 yuan per kg, this yields a gross profit of 1,200 yuan. This is a quick and effective project for improving land utilization and increasing farmers' income. 1. Selecting improved varieties and soaking seeds for sprouting: Choose varieties with high quality and yield, a relatively short growth period, relatively high tolerance to high temperature and drought

Six Improvements in No-Till Cultivation of Autumn Potatoes with Rice Straw Mulching
Autumn potatoes can be harvested in December and marketed as vegetable potatoes, giving relatively good returns. Adopting no-till cultivation of autumn potatoes with rice straw mulching not only saves labor and time, reduces labor intensity, and prevents environmental pollution caused by burning rice straw, but also yields about 1500 kg per mu, an increase of more than 10% over plowed and sown crops. Especially in recent years, in conjunction with production demonstrations, agricultural technicians have made some improvements to this technology, making it further mature. Specifically, these are the "six improvements": switch to early-maturing excellent varieties. Effective growth period of autumn potatoes

Key Techniques for No-Till Cultivation of Autumn Potatoes with Rice Straw Mulch
Autumn potatoes can be harvested in December and marketed as table potatoes, giving good returns. Adopting no-till planting of autumn potatoes with rice straw mulch not only saves labor and time and reduces labor intensity, but also prevents environmental pollution caused by burning rice straw, and can increase yield by more than 10% compared with plowed planting. The key cultivation points are as follows. 1. Select early-maturing, excellent varieties. The effective growth period of autumn potatoes is short, generally 80-90 days. Therefore, seed potatoes should be selected from varieties with early maturity, fast tuber enlargement, and good yield and disease resistance, such as Dongnong 303, Holland 15, etc.

How to prevent and control several common diseases of straw mushrooms?
① During the mushroom bud formation stage, control the temperature at 25-28°C. When the temperature suddenly drops below 20°C in early autumn, cover the shed with straw curtains for insulation; ② During the mycelium growth stage, the light should be dimmer to prevent strong light stimulation from causing premature mushroom bud formation; pile the straw firmly to help the mycelium connect tightly; ③ During the mycelium growth period, spray rotenone and dichlorvos around the culture material on the mushroom bed to kill pests such as millipedes and woodlice; ④ The spawn must be isolated or introduced every year and stored at a suitable temperature; ⑤ Regularly sprinkle water on the beds around the material blocks or irrigate in the bed furrows to keep the bed moist.
