The squash squash strips grow short and grow thick, which can seriously affect the quality of zucchini and reduce the income of vegetable farmers. Experts suggest that in the winter and spring season, zucchini should be prevented in advance. In winter and spring season, the greenhouse temperature and the ground temperature are low, and the light is weak. The photosynthetic efficiency of summer squash is low, and the nutrition accumulation of the plant body is less. Coupled with the decline in the root function of Zucchini, the absorption, transportation, and utilization of fertilizer and water are hindered, and the flower buds of Zucchini are poorly differentiated, resulting in an increase in short crude melons. In addition, if the concentration of vegetable melon medicine too much, too early to wipe melon, it is easy to lead to melon strip development is not normal, the formation of short crude melon; stay Guaduo, not sparse melon, melon strip growth and development of the necessary nutrients, will hinder The melon strips grow normally and form short, rough melons. Here, take measures to prevent short courgettes in summer: The first is to improve the environmental conditions within the shed, and the zucchini enters the nectar period, so that “high-temperature melon cultivation†is achieved. During the day, the shed temperature is maintained at 25°C, photosynthesis is enhanced, and photosynthetic products are accumulated. At night, the temperature is 12° C. to 14° C. to facilitate photosynthate production. Melon conveyors promote the growth of melons. In addition, timely picking leaves should be used to improve the ventilation and translucency between the rows and reduce nutrient consumption. The second is to strengthen fertilizer and water management. In the winter and spring seasons, it is recommended that functional fertilizers and top-fat fertilizers be applied in combination with topdressing, rooting and promoting vines to increase plant growth. At the same time, the leaf fertilizer was added to improve the photosynthetic function of leaves and delay aging. Third, pay attention to the concentration of wipes should not be too large, it is recommended to test and then apply. The time to wipe the flowers is the day before the opening of the female flower or the morning of the flowering day. Plant extracts are based on plants as raw materials.
