1. It is preferable to use raw materials for seed production, such as cottonseed husks, corn cobs, sawdust, bran, rice bran, gypsum, calcium carbonate, etc., and should be fresh, dry, free of mildew, and adulterated without any adulteration. Before use, it was exposed to sunlight for 1 to 2 days and ultraviolet rays were used to kill the pathogenic spores.
2. Rational use of material-based rice bran and bran is not only a good source of nitrogen for mycelium development, but also a carbon source. The amount of rice bran should be increased or decreased as the relative humidity of the environment changes. Excessive amounts are easily contaminated by bacteria. Therefore, to properly control its content in the 18% to 25%, high humidity season to be reduced to 18%.
3. Regulating the proportion of feed water Most of the water needed for the growth and development of edible fungi comes from the culture materials. Different filling containers and sealing materials are used in different cultivation seasons, and the ratio of feed water to water is not the same. Over-dried mycelium grows less and is delicate; over-wetness can cause mycelium decay and disease.
4, plug the invading mouth of the bottle or the bag must be a good mouth, Zhakou is very easy to cause the invasion of bacteria.
5, to prevent the culture material spoilage culture materials should be equipped with fashion bags and sterilization, or easy to acid deterioration. Sterilization should be thorough. Whether it is the production of strains or the cultivation of clinker, sterilization does not strictly lead to the occurrence of diseases.
6, strengthen the management of the germination period 1 appropriate cooling culture. Most of the germs are hi and high temperature. In addition to straw mushrooms can be properly cooled culture, so that although the growth rate of the mycelium is slow, but strong and powerful, while the pathogen significantly reduced. In particular, the raw material cultivation temperature should be below 20°C. 2 Hygroscopic culture. Edible fungus in the growth phase of mycelium requires air relative humidity is generally lower than the pathogen, so the air relative humidity in the germination period should be maintained at about 60%, effectively inhibiting the occurrence of bacteria. 3 timely turn inspection. Two to three days after the inoculation, the first turning inspection was performed and it was found that the infection by pathogenic bacteria was promptly picked up.
Additives mainly refer to various antibiotics, antioxidants, mold inhibitors, binders, colorants, flavouring agents, health care and metabolic regulation drugs, etc. are conducive to enhancing feeding effect, conducive to the production and storage of non-nutritive Feed Additives and their formulated products. It is mainly divided into food additives, feed additives, concrete additives, and oil additives.
Food additives refer to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are a term that refers to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are generally not food and may not have nutritional value, but they must conform to the above definition, that is, they do not affect the nutritional value of food, and can prevent food spoilage, enhance food sensory properties or improve food quality.
Feed additives, also known as feed additives, refer to the general term of additives manually added to formula feed in order to make up for the shortcomings of formula feed and some special needs. The functions of additives include: 1) insufficient nutrients in feed; 2) preventing deterioration of feed quality; 3) improving palatability of feed and utilization rate of feed; 4) enhancing disease resistance of feeding animals, promoting normal development and accelerating growth and production of feeding animals; and 5) increasing the output and quality of feeding animal products. The dosage of these special substances is very small, generally according to a few percent of the formula feed to several parts per million (mg/kg), but the effect is very significant. According to some data at home and abroad, it is considered that the average efficiency can be increased by 5%-7%, sometimes up to 10%-15%.
