How to choose and purchase good strains

Strain is the basis and guarantee to obtain high yield of edible fungus, and the quality of strain directly affects the economic benefit of edible fungus production. The following aspects should be paid attention to in the selection and purchase of improved varieties of edible fungi.

First, keep an eye on the market to select varieties. The prices of edible fungi are different in different regions, different seasons and different years. Mushroom farmers should not stick to the rules in seed selection, but should adapt to the circumstances and start from the following aspects.

1. Choose varieties with good prices, such as mushroom Zhongzhong "2796", Pleurotus ostreatus p54 "New Century", Xiaopinggu mushroom, straw mushroom v23, v35 and other varieties, usually in short supply, the price is good, can win with price, especially suitable for suburban development.

2. Select high-yield and high-quality varieties to win by quality and yield. These varieties can still achieve high economic benefits during the peak marketing period, and are more suitable for the development of large-scale edible mushroom bases for outward transportation.

3. Select new and excellent varieties. "scarcity is precious". Some rare and new varieties, such as Pleurotus eryngii, Pleurotus ostreatus, Pleurotus ostreatus, Zhenji Pleurotus ostreatus, Pleurotus ostreatus, etc., can be produced on a large scale with high price and good economic benefits. However, its characteristics and supporting cultivation techniques must be mastered when selecting.

Second, the selection of varieties should be "three-look". At present, there are still many fake and inferior bacteria in the market, which make it difficult for consumers to distinguish between true and false and easy to be deceived. Therefore, to select excellent bacteria, we should do a good job of "three views":

1. Look at the unit. It is necessary to choose units with high credibility, strong economic strength and strong technical force to purchase seeds. We should not simply pursue the cheap price, otherwise it is easy to be fooled, lose the big because of the small, and cause unnecessary economic losses.

2. Look at the brand. To choose the brand you are familiar with, do not blindly trust advertising, such as the conversion rate of 450%, 500%, anti-all miscellaneous bacteria, success rate of 100%, etc., are deliberate hype, can not be trusted.

3. Look at the strain. Bacteria have certain appearance characteristics, and many strains can judge their quality and degree of freshness from the appearance. Seed buyers should learn to observe the characteristics of strains and be good at distinguishing between good and bad strains and the old and new.

Third, be willing to spend money on improved seeds. Edible fungus is a kind of planting industry with a wide gap in economic benefits, such as 5 tons of cultivated materials with a high output value of tens of thousands of yuan and a low output value of only hundreds of thousands of yuan, and some even lose money. And if you can be willing to invest and buy high-quality bacteria, it can, to a certain extent, ensure high yield and high quality and reduce investment risk.
