Cultivate high-temperature mushrooms to control the "three passes"
The cultivation of mushrooms in summer has higher economic benefits. In order to grow mushrooms well in summer, there must be "three hurdles" of variety, fermentation and pest control. The main results are as follows: (1) the suitable high temperature type strains are Xincheng 96, Su Mushroom 1 and so on. The optimum temperature of Xincheng 96 is 18-36 ℃, 25-33 ℃ in greenhouse and 20-36 ℃ (24-33 ℃) in greenhouse. It is the most heat-tolerant strain at present. It is suitable for sowing in May-June and mushroom in June-September. Its greatest advantage is mushroom picking.

Comprehensive measures should be taken to prevent the growth of round eggplant.
At present, because the greenhouse begins to close at night for heat preservation, the night temperature is often too high, so that the round eggplant in the greenhouse grows seriously. In order to prevent the round eggplant from flourishing without setting fruit, the reporter found that vegetable farmers generally adopt the method of water control. However, it is difficult to achieve the desired effect by relying solely on water control in production, and there are many disadvantages of excessive water control, such as poor flower bud differentiation, abnormal fruit and so on. The author believes that there are many factors leading to plant growth, so comprehensive measures should be taken to control plant growth instead of blindly excessive water control. Temperature control tree. The suitable growth temperature of round eggplant is 25 in the daytime.

Soilless cultivation and Management of Phalaenopsis
1. Temperature. During the period of vegetative growth, the temperature is generally controlled at 20-35 °C. The temperature required for vernalization of large seedlings is 15-18 °C. The temperature requirement from arrow drawing to flowering is 18-20 °C at night and 25-30 °C from day to day. The ornamental temperature at flowering stage should be controlled at 15-20 °C. The temperature difference between day and night is generally more than 10 °C, let alone negative temperature difference between day and night. two。 Light. The light intensity of young seedlings (from 6 months old to 6 months old) is controlled at 5000-8000 lux; the light intensity of medium seedlings (6 months old to 6 months old) is controlled at 5000-8000 lux.
