How many days does a watermelon generally need to mature
After planting watermelons, how long does it take to complete the entire growth and maturity period? There will be certain differences depending on the variety and the region where they are planted. The time is shorter in warm regions and longer in cold regions. The planting time is shorter in the Yangtze River Basin,. and longer in the north. However, some early-maturing varieties take less time than late-maturing varieties, and greenhouses take less time than open fields. Exactly how long is needed will be introduced in detail right away.
1. Maturity time
If watermelons are generally planted in open fields in March, they will mature in more than June. Early-maturing varieties need about 90 days, such as Early Spring Jade; medium-maturing varieties need about 100 days, Xinong R; late-maturing varieties need 120 days, such as Hongyou No. 2, and they generally all mature from June to July. For greenhouse planting, choose early-maturing varieties, plant around February, and they can reach the market at the end of April or in May.
2. Growth period
The entire growth period mainly has four stages. The germination stage is the period when the cotyledons unfold, mainly relying on seed nutrients and cotyledon photosynthesis to provide nutrition, and mainly growing the root system. It needs a temperature above 25 degrees. The seedling stage, from growing true leaves to growing six true leaves, mainly involves leaf and stem growth. It needs a temperature above 20 degrees. The vine-running stage mainly involves rapid plant growth and the opening of female flowers. It mainly shifts to reproductive growth and needs a temperature above 20 degrees. The fruiting stage, from flowering to maturity, mainly involves flowering and fruiting, and nutrient supply, and needs a temperature between 20 degrees and 26 degrees.
3. Maturity standards
When the blossom end is sunken and the stem is green, it means it is mature. For patterned melons, if the stripes are clear, it is mature. For black melons, if the color is glossy and black, it is mature. If the rind is smooth, it is relatively mature. If a fruit of the same size becomes lighter in weight, it is mature. The common method of tapping the melon generally means a dong dong sound indicates maturity. If the sound is very deep and low, it is overripe. If it is a melon you grew yourself, you can also put it in water to test it. If some float to the surface, it is just right and mature.
4. Maturity period
In the south they mature earlier, at about June, and in the north they mature in July. For protected cultivation, they can be cultivated in all four seasons, and the maturity time must be calculated according to the planting time. Planted in early spring, they mature in May. Planted in autumn, they can also mature in winter. Depending on the variety, open-field planting can have maturing fruit from June to September. Sometimes it also depends on climate and altitude. At high altitude, the maturity period will be later, and in dry and warm climates it will be earlier.
How many days after planting watermelons they mature mainly depends on the variety, planting site, planting climate, altitude, environment, temperature and other influencing factors, and mainly also depends on the watermelon's own maturity period. But generally it is all within three to four months. I hope the above information will be helpful to everyone.
