Talking about the successful experience of planting mushrooms in greenhouses, He Minghua revealed three secrets of success. The first is the application of advanced science and technology. He Minghua combined the knowledge he learned with other successful experiences and applied it to actual planting, which not only saved time and effort, but also improved the output value. The second is to select excellent new varieties, strictly control inoculation, and put an end to mixed bacteria infection. In the past, old varieties had low yield and poor disease resistance, and they always encountered mixed bacteria infection during planting, which seriously affected the yield of Pleurotus ostreatus, and the quality of the produced Pleurotus ostreatus could not pass the test. In order to improve the varieties, he made a special trip to introduce excellent new varieties from neighboring cities, and the effect was much better than that of traditional cultivated varieties. The third is to strengthen management to ensure the development of strains under suitable conditions. Wind, light, temperature and humidity are important factors that restrict the growth of Pleurotus ostreatus. Without suitable temperature and good environment, no matter how good the variety is, it will not help. He Minghua keeps in mind the lessons of this failure, conscientiously completes every link, and allows mushrooms to thrive in a suitable environment.
