Raising cotton seedlings in foam tray substrate with hydroponics gives higher returns
The widely promoted F1 hybrid cotton variety Ezamian No. 10 was selected to compare the cultivation effects of plastic soft-tray substrate seedling raising, foam tray substrate hydroponic seedling raising, and fertile-soil nutrient bowl seedling raising. The results showed that on alluvial fluvo-aquic soil in the Wuhan area, with cotton planted in continuous cropping with rapeseed, the net income per unit area was highest with foam tray substrate hydroponic seedling raising, followed by plastic soft-tray substrate seedling raising. Therefore, matching cotton varieties with simplified, light-labor cultivation techniques selected according to local conditions and promoting them together can improve the profitability of cotton growing.

Detailed Explanation of Key Techniques for Outdoor Substitute Substrate Cultivation of Shiitake Mushrooms
Shiitake mushroom (Lentinula edodes) is one of the important edible fungi, originally wild, and was first artificially cultivated in China over 800 years ago. Substitute substrate cultivation uses artificial mushroom logs made from sawdust, mulberry branch powder, cottonseed hulls, etc., to replace natural logs for cultivating shiitake mushrooms. This method has wide resource availability, high yield, a short production cycle and high economic returns, making it very suitable for farmers to cultivate. 1. Strain selection. There are many types of shiitake varieties, and the commonly used ones are of the medium-low temperature type. The optimal environmental conditions for the mycelial growth of this type of shiitake are an air temperature of 24-27°C, a substrate moisture content of about 60%, and no light or weak light. The optimal environmental conditions during the fruiting stage

Key Technical Points for Field Cultivation of Shiitake Mushrooms on Substitute Substrates
With the advancement of science and technology and the development of the market economy, shiitake mushroom cultivation is also continuously improving and innovating. Not long ago, the editor received phone calls from farmers such as Li Xiliang of Baigenli Village, Kele Town, Nenjiang County, asking about the techniques for field cultivation of shiitake mushrooms. We have specially selected and compiled the manuscript "Cultivation Techniques for Field Cultivation of Shiitake Mushrooms on Substitute Substrates," hoping it will be of help to you. 1. Preparation of the cultivation substrate There are many formulas for the culture medium used in field cultivation of shiitake mushrooms on substitute substrates. Two are introduced here: one is 80% hardwood sawdust, 10% wheat bran, 7% rice chaff, 1% gypsum powder, 2% soybean cake powder, and 0.1-0.2% 50% wettable

How to cultivate lion's mane mushroom (Hericium erinaceus) from spent mushroom substrate? Detailed new technique
Lion's mane mushroom is named for its resemblance to a monkey's head and its delicious flavor, and has long been known by the saying "monkey's head among mountain delicacies, bird's nest among sea treasures." During mushroom spawn production or transfer, contaminated spawn sometimes appears due to carelessness in sterilization, disinfection, inoculation, culturing and other steps. If contaminated spawn is discarded in the wild, it causes environmental pollution; if the substrate is dug out and the spawn bottles are washed for reuse, it wastes labor and time. But if contaminated spawn is used to cultivate lion's mane mushroom, waste can be turned into treasure with twice the result for half the effort. The specific method is as follows: 1. Collect contaminated spawn and sterilize. Promptly

Can distiller's grains be used as a substrate for growing oyster mushrooms?
It is acceptable to use distiller's grains instead of wheat bran as a supplement for producing oyster mushrooms. The usual amount is about 20%, and the other 70-80% can be cottonseed hulls, sawdust, or similar materials. Because distiller's grains are fairly acidic, some lime or similar material should first be mixed in before use, bringing the pH down to 6-6.5.

High-yield technique for bag cultivation of oyster mushroom on fermented coarse sawdust substrate
At present, with the development of the edible mushroom industry, the demand for raw materials is also growing. In recent years, the price of fine sawdust in the three northeastern provinces has soared, while coarse sawdust has become waste (such as the coarse sawdust sifted out through the electric sieve on the chipper and the coarse sawdust produced by the branch and twig crusher). The author used the locally abundant coarse sawdust as the main fermentation ingredient to cultivate oyster mushrooms, and the summary is as follows: 1 Test strain Oyster mushroom 2026, whose mother culture was provided by the Shijiazhuang High-tech Edible Mushroom Station in Hebei. The stock culture was a corn kernel medium, with corn kernels 99% and gypsum 1%. Soak or boil the corn kernels,

Preliminary Report on the Results of Substrate Replacement Cultivation Trials of Gastrodia elata
Artificial cultivation of Gastrodia elata mainly uses the trunks of broadleaf trees such as oak, birch, hazel, elm, willow, jujube, pagoda tree, and wild cherry, and requires a diameter of more than 5 cm. For a long time, this has caused severe damage to forest resources, which are now on the verge of exhaustion. Therefore, research on substrate replacement cultivation techniques for Gastrodia elata has gradually become a hot topic. There are already precedents for substrate replacement cultivation using corn cobs, shrub stems, corn cobs, corn pith, branches, and straw, but no reports on the cultivation of Gastrodia elata with cottonseed hulls have been seen. For this reason, this trial was conducted, and the preliminary results are reported as follows: 1 Materials and

What is the effect of adding plant ash to oyster mushroom substrate
When cultivating oyster mushrooms on raw substrate, adding an appropriate amount of plant ash to the substrate has certain benefits for the growth of oyster mushrooms. Because plant ash is alkaline, it has a disinfecting and sterilizing function and can inhibit the growth of various contaminating microorganisms. At the same time, plant ash contains various trace elements such as calcium, magnesium, iron and phosphorus, which can increase the nutrient content of the substrate. In addition, plant ash has the effect of absorbing heat and raising temperature, which can create a good growing environment for mycelial growth. The method of adding plant ash to the substrate is simple: just add 3%-4% after the substrate has fully absorbed water.

Why oyster mushroom mycelium fails to fruit for a long time after fully colonizing the substrate, and how to fix it
In oyster mushroom cultivation, you sometimes run into bags or blocks whose mycelium grows very well but, after fully colonizing the substrate, produce no mushrooms for a long time. The main causes and remedies are as follows: 1. The oyster mushroom variety does not match the season. The temperature type of the spawn differs too greatly from the air temperature at cultivation time, which is to say the sowing time was chosen poorly. For example, if a medium-to-low-temperature oyster mushroom spawn is sown at the turn of spring and summer, the mycelium fully colonizes just as the hot season arrives, making fruiting very difficult. Remedy: dig a trench in a shady spot, arrange the bags in it and cover them with soil to oversummer; when the autumn cool arrives and conditions are suitable, dig away the soil cover and carry out fruiting management to reduce losses.

How do you deal with a lack of water in the substrate during the later stage of oyster mushroom cultivation?
The first flush of oyster mushrooms accounts for about 40% of the total yield. Generally, after the second flush is harvested, because the water in the substrate is almost used up, even if mushrooms can still come out they are sparse, with thin and weak fruiting bodies, loose and dry flesh, and poor taste. To increase the yield, the following methods can be used to supplement water and nutrient solution: (1) The upright bag hole-irrigation method: the soaking method requires a water-holding container, but in some cases a small container or other reasons make it inconvenient, so this method can be used. Stand the fungus bags upright on the floor of the mushroom house, pull up the edges of the plastic bag so that water can be retained after watering, then
