At present, greenhouse strawberry production enters middle and late stages. In addition to strengthening pest control and controlling temperature and humidity, the most important is to do a good job of post-fertilization and watering. Therefore, the following problems should be paid attention to in production and corresponding management measures should be taken. 1. Watering irrigation is uneven. The reason is that in order to save water and reduce the humidity in greenhouses, some farmers use drip irrigation to irrigate them. This way, when they are irrigated, they will not cause the greenhouse temperature to drop too quickly, reduce the occurrence of strawberry diseases, and increase the yield of strawberries. However, due to the water quality, some drip outlets were often blocked during the later period, resulting in uneven irrigation and affecting the fruiting of strawberry blossoms. Management measures: According to practical experience, in later irrigation, it is a reasonable method to change drip irrigation to flood irrigation under the membrane. The specific method of operation for sub-film irrigation is to uncover the film between the two bowls, place the sprinkler directly under the membrane sulcus, and squeezing the water thoroughly. This method of irrigation can make water guide from the bottom of the strawberry upwards, reducing the soil compaction caused by irrigation, and the irrigation under the membrane can also reduce the number of irrigation times, which saves labor and labor. Generally, the viscous soil can be fertilized once every 15 to 20 days, and the sandy soil can be used once every 10 to 15 days. 2. After entering the secondary results, some strawberries appeared to be defertilized. If no nutrient supply is strengthened at this time, it will easily affect the yield and quality of the second crop. And flowering is not suitable for foliar fertilizer, adding a certain degree of difficulty for fertilization. Management measures: Increased use of strawberry tracer, Penshibao, potassium dihydrogen phosphate and other highly effective trace element fertilizers for strawberries to increase soil organic matter content, supplement missing trace elements such as manganese, molybdenum, zinc, and calcium, and increase supplemental efficient phosphorus. Potassium fertilizer. The method of application is that the diluted high-efficiency fertilizer is applied evenly with water when irrigating, and generally 25 kg of special fertilizer is applied per acre. 3. The occurrence of pests and diseases is more serious. With the increase of temperature, pests such as powdery mildew, gray mold, and worms are relatively increased, which seriously affects the quality and yield of strawberries. Management measures: In advance prevention, hanging a sticky board every 2 meters in the shed can reduce the amount of maggots. The site where the disease has already occurred can be fumigated with an aerosol after picking the strawberries. During specific operations, it is important to pay attention to the pollination bees first moved outside the shed to prevent damage to the bees. To completely seal the place where the ventilation is done, gas fog fumigant should be used in the evening and ventilation should be performed in the morning on the second day.
