Due to improper cultivation and management, or climatic factors, a large number of melons often appear, seriously affecting production. Causes of melon and prevention methods: Melon Guam is too weak, less nutrient accumulation, and at the same time bring melon 2-4, we must turn melon. Preventive measures: Apply appropriate amounts of bio-fertilizer, apply 1 kg of zinc sulphate to Mushi, increase the leaf area, and increase growth; raise the night temperature to around 20°C for 2-3 days, and increase the leaf area by 25°C during the day; Some melons, concentrated nutrition first expand 1-2 melons. Temperature difference between day and night In the late period of the guava period, the soil is longer than 20°C for a long time, the temperature difference between day and night is less than 10°C, and the light and the product are consumed in large quantities and the cucurbit will be melonized. Preventive measures: Master 25-32°C during the day and 13-18°C in the evening; For the prosperous greenhouse, control the prosperous melons; Few melons are sprayed with sprayed probiotics and high-potassium nutrient solution to promote sitting. And melons are swollen. Plant leaves over prosperous melons The long side of the cucumber plant is a long melon. If the long stems of the long stems and long stems of the plant grow, the vegetative growth will be too prosperous, and the growth of the melon will be inhibited. Preventive measures: After planting seedlings, control water, control temperature, control nitrogenous fertilizers, promote seedling roots, inhibit vegetative growth, and promote sitting cucumbers. The temperature is too low for melons During the day when the temperature is lower than 20°C, the leaves of cucumbers cannot be used for photosynthesis. If they are malnutrition for three consecutive days, empty cucumbers will appear. Preventive measures: increase the covering at night, exposing the grass cover early in the day and increasing the temperature of the shed. Potassium deficiency The ratio of nitrogen, phosphorus and potassium needed for cucumber production is about 5:2:6, and 78% of the potassium is absorbed by the fruits. If potassium is insufficient, it will turn into melon. Preventive measures: Basal fertilizer applied 25-50 kg of high quality potassium carbonate per acre in the case of applying organic fertilizer; spraying 99% high-purity potassium dihydrogen phosphate on a regular basis during the period of nectarine treatment; Nitrogen and phosphorus fertilizers to prevent potassium absorption. Diseased melon Cucumber often lost in the downy mildew, gray mold and black spots, infected plants poor photosynthetic ability to facilitate melon. Preventive measures: Prevent disease.
