Winter defense zucchini short and thick melon
Zucchini melons grow short and grow thick, which will seriously affect the commercial value of zucchini and reduce the income of vegetable farmers. It is recommended to prevent the occurrence of short and thick cucumbers in the early winter.
In winter, the greenhouse temperature and ground temperature are low, the light is weak, the photosynthetic efficiency of the zucchini is low, and the nutrient accumulation of the plant body is small. In addition, the function of the roots of zucchini decreased, the absorption, transportation and utilization of fertilizer and water were blocked, and the flower bud differentiation of zucchini was poor, resulting in an increase in short and thick melons. In addition, if the concentration of the vegetable farmer is too large, the time of the melon is too early, it is easy to cause the melons to develop abnormally, forming short and thick melons; leaving more melons, not sparse melons, lack of nutrients for the growth and development of melons, will It hinders the normal growth of melons and forms short and thick melons.
Measures to prevent zucchini short and thick melon: First, improve the environmental conditions in the shed, the zucchini enters the melon period, and should be high-temperature to raise melon, keep the shed temperature at 25 °C during the day, enhance photosynthesis, accumulate photosynthetic products, and maintain the temperature at 12 °C at night~ 14 ° C, in order to facilitate the transport of photosynthetic products to melon strips, promote the growth of melon strips. At the same time, it is necessary to pick up the leaves in time to improve the ventilation and light transmission conditions between the plants and to reduce nutrient consumption.
The second is to pay attention to topdressing. Functional fertilizers are combined with fully water-soluble fertilizers to raise roots, promote vines, and increase plant growth. It is also necessary to supplement the foliar fertilizer to improve the photosynthetic function of the leaves and delay aging.
The third is to pay attention to the concentration of the melon drug should not be too large, we must first test and then apply, the time of the melon is appropriate to the day before the opening of the female flower or the morning of the flowering.
