The intertidal management of straw mushroom has three key points: First, prevent pests from invading. Once found, they should be completely killed in the first time. Second, the prevention and control of disease-causing bacteria can be used in moderation in the intertidal zone, such as spraying high-efficiency, low-toxicity and low-resistance drugs. Third, after cleaning up, it should be ventilated and protected from light, so that the hyphae can be rehabilitated to expand the biomass; conditional can be used to replenish the base.

Thermoplastic starch is also called "non-structured starch", which can make the starch structure disordered and thermoplastic by certain methods. Starch molecules for polysaccharides molecular structure, containing a large number of hydroxyl, due to its intermolecular and intramolecular hydrogen bond action, so that its melting temperature is higher, and its decomposition temperature is lower than its melting temperature, so in the heat processing, starch molecules did not melt and first decomposed. The traditional mechanical processing method of plastic is mostly heat processing, so to make starch - based whole starch plastic needs to make natural starch thermoplastic. This thermoplasticity can be achieved by changing the crystalline structure inside starch molecules. Destroy intramolecular and intermolecular hydrogen bonds, disrupt the double helix crystal structure of starch molecules, which will reduce the melting temperature of starch and make it thermoplastic.
