How to plant watermelon
The editor provides netizens with an explanation of how to plant watermelon and the techniques and management of watermelon cultivation in the green plant and flower aspect. Next, the editor will introduce the topic.
The most important factor for selling watermelon well is the sweetness of the watermelon, which is related to its sugar content. The higher the sugar content, the sweeter the watermelon. The sugar content of watermelon is associated with the variety and cultivation methods, with sweeter varieties having higher sugar levels. During cultivation, increasing the efficiency of photosynthesis in the plants, promoting the formation of organic matter, and converting it into sugar can enhance the sweetness of watermelon. Below are some specific methods compiled by the editor of Huinong Network to increase the sweetness of watermelon, let's take a look together.
Key points of planting methods to increase the sweetness of watermelon:
① Choose sandy loam soil with a higher potassium content to plant watermelon.
If the soil is heavy, it needs to be improved to increase its permeability.
② Scientific fertilization
Mainly use base and organic fertilizers, with a small amount of topdressing, supplemented with boron and zinc fertilizers. The ratio of nitrogen, phosphorus, and potassium should be 3:1:2. During the vine elongation stage, foliar fertilizers should be applied appropriately, reduce nitrogen fertilizers during the fruit expansion stage, and increase potassium fertilizers, avoiding excessive application of nitrogen fertilizers.
③ Light environment
“Sunbathe when young, cover when ripe.” Watermelon loves light. Insufficient light in the early stage can lead to slow fruit development and low sugar content, while excessive light in the later stage can easily cause fruit cracking, especially the direct sunlight on watermelon after a summer rainstorm should be avoided.
④ Frequent light watering, water control before harvesting
Watermelon absorbs a lot of water during its fruiting stage but does not tolerate waterlogging. The soil should be kept moist but not flooded. If the soil moisture content is low before harvesting, the watermelon will be sweeter. Watering can be stopped about a week before harvest.
⑤ Harvest at the right time
The sweetness of watermelon is highest when ripe. After ripening, the fruit begins to age, and the sweetness decreases. It should be harvested in time. On hot days, it can be harvested 1-2 days earlier. The longer the early or delayed harvest, the lower the sweetness.
For watermelon grown in greenhouses or other protected areas, methods such as increasing light intensity, adding day-night temperature differences, extending the duration of light, and applying more carbon dioxide can also be used to increase sugar content.
