Technical points for cultivating Gastrodia elata with rice husk culture medium
Rice husk is a good "soil" ingredient for culturing Armillaria mellea and cultivating Gastrodia elata in plain areas. The "soil" it forms, namely the filler, is loose, well aerated, has good water permeability and is rich in nutrients, which is beneficial to the growth of Armillaria mellea. The rhizomorphs on the fungus branches and fungus wood cultured with it are thick and vigorous, and the Gastrodia elata cultivated with them grows well. The method is: (1) Rice husk fungus substrate culture: use 1 part rice husk and 1 part yellow sand (volume ratio 1:1) or 3 parts rice husk and 2 parts yellow sand, add water and mix thoroughly, humidity 40%

How to make watermelon rind taste good? The method for making licorice watermelon rind strips
Watermelon rind is rich in carbohydrates, minerals and vitamins, and has effects such as clearing heat and detoxifying, and promoting urination. The following introduces the technique for making licorice watermelon rind strips: Cut into strips. Thoroughly wash fresh watermelon rind with clean water, drain off the water, remove the green outer skin and the red flesh, then use a stainless steel knife to cut the watermelon rind into strips 0.2 cm wide and 6 cm long. Salting. First mix sodium benzoate and table salt, in amounts of 0.1% and 10% of the weight of the watermelon rind strips respectively. Then, in a container, salt in the order of one layer of watermelon rind and one layer of mixed salt, with a somewhat larger amount of mixed salt on the topmost layer. The salting time is generally 24 to 48 hours. Rinsing. Put the salted watermelon rind strips into a container holding clean water, changing the water once every 1 hour, until the salt content in the watermelon rind strips drops to 1% (the salt content is tested with a handheld salinity refractometer). Sugar processing. Put the rinsed watermelon rind strips into a bamboo basket and drain off the water. Then, in a container, process with sugar in the order of one layer of watermelon rind strips and one layer of sucrose. The amount of sucrose used is 20% of the fresh watermelon rind strips, and the sugar processing time is 24 to 48 hours. Baking. Take out the sugar-processed watermelon rind, drain off the sugar liquid thoroughly, arrange it evenly on a baking tray, send it into the drying room, and bake at 65 to 70 degrees C until the moisture content of the watermelon rind is 25%. Auxiliary ingredient formula. Calculated per 100 kg of fresh watermelon rind strips, prepare the auxiliary ingredients: sodium saccharin 0.05 kg, monosodium glutamate 0.2 kg, citric acid 0.05 kg, table salt 0.5 kg, potassium sorbate 0.01 kg. Soaking the auxiliary ingredients. Place the dried watermelon rind strips in a container. Dissolve the auxiliary ingredients according to the formula in licorice water, pour into the container, and mix the watermelon rind strips thoroughly from top to bottom. On the second day, mix from top to bottom another 1 to 2 times, leave for 2 days, take out the watermelon rind strips and bake them. The licorice aqueous solution is made by boiling 4 kg of licorice and 25 kg of water per 100 kg of fresh watermelon rind strips, and filtering it. Baking. Evenly arrange the watermelon rind strips that have been soaked with auxiliary ingredients on a baking tray, and send them into the drying room for baking. It is suitable to control the drying room temperature at 60 to 65 degrees C. During baking, turn them several times, and when the moisture content of the product drops to about 25%, the baking is finished. Mixing in licorice powder. Cool the watermelon rind strips at room temperature. Mix licorice powder (used in an amount of 0.1% of the fresh watermelon rind strips) into the watermelon strips, and mix evenly to obtain the finished product.

Key High-Yield Techniques for Cultivating Oyster Mushrooms on Rice Straw
High-Yield Techniques for Cultivating Oyster Mushrooms on Rice Straw 1. Selecting spawn: Experiments show that the relatively ideal strains include: the low-temperature type 792 and 118 oyster mushrooms; the medium-temperature type Xinnong No. 1, 9400 oyster mushroom, and Hypsizygus marmoreus; the high-temperature type Hainan No. 2, etc. (All of these spawns can be provided by the Binhai County Edible Fungi Research Institute.) 2. Seasonal scheduling: Along the middle and lower reaches of the Yangtze River, sowing can be done from early August to mid-February of the following year, with mid-September to mid-November being the best sowing period. 3. Rice straw selection: Choose fully dried, mold-free, golden-colored rice straw

Key Technical Points for Autumn Potato Cultivation with Rice Straw Mulching (Part 2)
4. Timely early sowing. Potatoes prefer a cool climate, and the sowing period should be when the daily average temperature steadily drops below 25°C. In plain and hilly areas below 500 m in altitude, the suitable sowing period is from late August to early September; in low mountainous areas at 500-800 m in altitude, the suitable sowing period is in late August. 5. Reasonable close planting and sufficient base fertilizer. For fields with rice stubble potatoes intercropped with rapeseed, both potatoes and rapeseed are planted in wide-narrow row patterns. For potatoes, the wide row is 0.6 m, the narrow row is 0.2 m, the hill spacing is 0.22 m, and about 700

After rice is flooded, attention must be paid to the three prevention measures
From mid-to-late June to mid-to-late July, southern regions are often hit by heavy rain, and some areas are prone to flooding disasters. If flooding occurs, in addition to carrying out conventional remedial measures, attention must also be paid to preventing outbreaks of bacterial diseases and mass outbreaks of migratory pests. Prevent the spread of bacterial brown stripe disease. As floodwaters overflow, the pathogen spreads and is transmitted and infects through wounds on rice plants caused by rain and floodwaters. The resistance of submerged rice plants declines, which is more conducive to disease spread. There is a process from after flooding to disease spread, therefore, for middle-season rice in flooded areas,

How to manage water and fertilizer well after rice is hit by floods
What should be noted when righting and washing rice seedlings? For flooded paddy fields, drain the standing water promptly and right the lodged seedlings; clear the ditches in time to lower the groundwater level. Where irrigation facilities have suffered heavy damage, organize forces promptly for emergency repairs. After the water in the paddy field recedes, open ditches to drain it, so that soil water in the field seeps into the ditches and is discharged, lowering the field moisture content as quickly as possible, so that the floating mud formed by flooding gradually settles and compacts, thereby promoting new root growth. For fields that have been submerged for a long time, the water can be drained off all at once in rainy weather; if there is scorching sun and high temperature, drain gradually, first letting
