At present, the autumn squash has been in the late stage of growth. Affected by the low temperature and low temperature, the phenomenon of rotten melons and melons in the shed is widespread, and effective measures should be taken to increase the rate of saplings.
Supplementary nutrition Anti-melon melons In the late growth stage of zucchini, especially at low prices, many vegetable farmers are neglecting management, not watering and fertilizing, causing severe drought and lack of fertilizer in sheds, coupled with low ground temperature in winter and roots absorbing nutrients. The ability is weak, and the photosynthetic products produced by the leaves are small, so it is easy to form the melons due to insufficient nutrition supply. The current management is focused on cultivating roots and cultivating roots to increase the vitality of the root system. The addition of Apollo 963 nutrients, biological fertilizers and other fertilizers can improve the soil and create a good environment for root growth. Combine watering and fertilization to avoid the use of inferior fertilizers with high levels of hormones. Foliar can also be sprayed with aromatic nutrient, Zhixin and other full-fledged foliar fertilizers to supplement plant nutrition and enhance leaf activity.
The major diseases that cause moisture to prevent rotten melons are the gray mold, soft rot, sclerotia and so on. These diseases are prone to happen when the humidity is high in the shed. In winter season, in order to ensure that the temperature of the shed is rarely open and ventilated, it is easy to cause excessive humidity in the shed. Therefore, comprehensive measures should be taken to reduce the humidity in the greenhouse as much as possible while meeting the growing needs of the plants. According to soil moisture, timely watering, small water pouring, immediately warming water the next day to remove moisture; cover film, straw, etc., reduce the evaporation of surface water; reduce the number of spray, pay attention to the use of smoke agent. In addition, we must promptly remove burnt, rotten melon and diseased leaves to prevent pathogens from spreading and infecting. Remove the burnt-out and diseased melons and put them on plastic bags. Carefully remove them and take them out of the shed.
Adjusting the temperature to regenerate the melon in the winter, the outside temperature is relatively low, and the air temperature in the shed must be taken into consideration before ventilation and dehumidification. During the day, the temperature of the canopy is controlled at about 25°C, and at night it is controlled at 13 to 15°C. This temperature is most conducive to high yield and high quality.
