Summer bright light, high temperature, high humidity environment, resulting in more difficult cultivation of zucchini, improper management, prone to malformation melon, disease, weight, production is also significantly lower than the spring and autumn. In order to improve the efficiency and efficiency of summer squash, the management should pay attention to the following aspects.
1. Must be sparse. In summer, the planting temperature is high, and seedlings grow fast. If the planting density is high, diseases such as virus disease and silver leaf disease are easily caused, resulting in reduced production.
2. Pollination. Summer summer squash from the planting to the clean garden only about 70 days, the management is more difficult, the output is only half of spring and autumn squash production, improper management of lower yield. In order to increase yield, many vegetable farmers are both spraying melons and wiping melons. When female flowers appear at the growing point, they begin to spray flowers and promote melons. When the female flowers of zucchini are opened, they begin to wipe melons. This increases the fruit setting rate. However, the number of malformed melons has also increased significantly. Therefore, the vegetable growers only adopt a method that promotes sitting and melons. If using guava spirit, it is necessary to sparsely melon so as not to prematurely decay the plant and produce a large amount of stubble melons.
3. Pay attention to seedling growth and do a good job of controlling the work in time. Some growers who grow this cornice in the first year can easily overlook this work. In the summer, they grow fast. If they can't control it easily, they can easily cause run and cause some young cubs to come out and not sit down. This phenomenon is because Failure to do a good job in time control, vegetative growth and reproductive growth are not coordinated.
4. Prevent pests and diseases. The main diseases of squash are powdery mildew, gray mold, viral disease, bacterial leaf blight, and physiological diseases. The pests mainly include aphids, whitefly, red spider, and Liriomyza sativae. The growers should promptly spray and prevent it.
5. Insect nets. If it is cultivated in protected areas, it is recommended that the ventilation openings be covered with 40-60 mesh insect-repellent nets, which can effectively prevent the entry of pests and prevent the occurrence of viral diseases.
6. Cover the shade net. Sunshade nets can cover strong light and have a significant cooling effect; prevent rainstorms, reduce the impact of heavy rain on the ground; reduce evaporation, and ensure drought protection; avoiding pests, the use of silver-gray shading nets to cover aphids and prevent virus diseases is very effective.
7. Laying mulch. In summer, it is recommended to use black mulch film. The black mulch film can maintain water and prevent grass. At the same time, it can also increase the growth time of summer cucurbits, which is longer than growth without mulching film.
