Greenhouse melon water and fertilizer management technology (summer melon high-yield cultivation and fertilization methods)

Water and fertilizer management technology for greenhouse melon

① Planting

After the melons are planted but before they start to vine, they need less water . Watering should be controlled to prevent lowering the ground temperature and promote root growth.

② Extension period

When the melon spider enters the vine extension stage, the water requirement gradually increases. Water once during the vine extension period to promote stem and vine growth .

③Flowering period

During the flowering and fruiting period of melons, the soil and air should be kept moist to extend the pollination time, which is beneficial to pollen germination and young fruit enlargement. The soil should be kept dry and wet at the same time, thus promoting fruit setting.

④ Water and fertilizer during fruit setting period

After the melons are firmly planted, the melon plant needs a lot of water and is very sensitive to water shortage . If the water needs of fruit development cannot be met, cell elongation will be restricted and it will not expand normally, and the fruit will become significantly smaller or even deformed.

Therefore, the number and amount of irrigation can be appropriately increased to keep the soil moist, but it is also not advisable to irrigate too much at one time to cause waterlogging on the ground.

⑤ Water and fertilizer management during fruit expansion period

When the melons enter the late stage of swelling, the amount of watering should be controlled, and watering should be stopped 7 days before harvest to improve the quality and appearance of the commercial melons. This can prevent the fruit from being too wet, which will cause the fruit flavor to become lighter, and avoid cracking and rot during transportation and marketing.

Topdressing technology for spring melon in greenhouse

The topdressing plan for melons in greenhouses depends on soil type, fertility level, climatic conditions, variety and planting density.

Generally, 5kg of Jinkede silicone fertilizer is used to fertilize one acre of melon, once after the seedlings have grown, at the early flowering stage, and at the early fruiting stage, to promote root growth and increase root capacity.

This method of top dressing shortens the internodes of melons, prevents excessive growth, improves pollen vitality, increases flowering and fruiting, increases skin hardness, makes fruits more resistant to impact, extends the shelf life by 7-15 days, and improves the taste.

Technology and methods of foliar fertilization of melon

① Seedling stage

Mix 30ml of Jinkede silicone foliar fertilizer in a spray pot (30 pounds of water), spray once every 7 to 10 days, spray twice .

②Growth period

Mix 50ml of Jinkede silicone foliar fertilizer in a spray pot (30 kilograms of water), spray once every 7 to 10 days, and spray 4 to 6 times continuously .

③Long-term

Mix 80ml of Jinkede silicone foliar fertilizer in a spray pot (30 pounds of water), spray once every 7 to 10 days, and spray 3 to 4 times in a row.

After spraying in this way, the melon plants will grow strong, with thick leaves and high chlorophyll content, which will improve photosynthesis, increase pollen vitality, produce more flowers and fruits, and increase production by 10%-20% .

If the melons are put on the market 5-7 days earlier , the melon skin will be thin, the flesh will be crisp and sweet, and the sugar content will be high. In addition, in terms of pests and diseases, vine blight, wilt, virus disease, spider mites, melon aphids, leafminers and other pests and diseases will be significantly reduced.
