Knowledge introduction of beauty melon

Beauty melon

Black Beauty watermelon is a representative of small-fruit watermelons. The skin of the watermelon is dark green and shiny. The watermelon is long and oval, and the weight of a single watermelon is generally 2-4 kilograms. The flesh is bright red, the seeds are small, and the sugar content is extremely high, generally reaching more than 13%.

The fruit of watermelon is composed of three parts: peel, flesh and seeds. The peel is developed from the ovary wall, and the flesh is developed from the placenta tissue. In the initial stage of watermelon fruit development, that is, within 14 days after flowering, the weight of the peel accounts for a large proportion of the fruit, and then the weight of the flesh gradually increases, so that the weight gain rate of the flesh is greater than that of the peel. Not only that, the content of soluble solids increases fastest 12 to 24 days after flowering. There is a sequence in the speed of watermelon fruit weight gain: the longitudinal diameter develops first; the transverse diameter gains weight later. It can be seen from this that the development of the top of the fruit is earlier than the development of the waist of the melon. Therefore, the development of the top of the watermelon fruit is a very sensitive area. When the fruit is ripe, the middle gelatinous layer of the placenta cells begins to dissociate, the gap increases, and a large number of giant juicy thin-walled cells are formed.

Varieties of melon

There are four types of peel colors: white, green, black, and mottled. The flesh can be divided into three types: white, yellow, and red. The color and size of the seeds are white, yellow, black, and brown. The number of seeds in a single melon is usually around 200 to 300. The above conditions vary depending on the variety.

Watermelon can be divided into three categories: early-maturing, mid-maturing, and late-maturing varieties. Early-maturing varieties of watermelon are generally not resistant to storage and have thinner rinds. The time from flowering to maturity is short, about 28 days. For example, early-flowering watermelon belongs to early-maturing varieties, and the rind thickness of this type of watermelon is 0.7 to 1.0 cm. Mid-maturing varieties take 33-35 days from flowering to maturity, and the rind thickness is 1.13 to 1.2 cm, such as the chicken claw gray variety of watermelon. Late-maturing varieties take 38 to 40 days from flowering to maturity, and the rind thickness is 1.4 to 2.0 cm. For example, the frozen melon variety of watermelon belongs to the late-maturing variety. However, the same variety of watermelon may also mature very early or late due to inconsistent fruit setting periods.

Cultivation and management of melon

1. Sowing period: February to April in spring and June to the end of August in autumn are the best. The early growth period of spring is in the low temperature period, and the late growth period is in the high temperature period, while the autumn is the opposite. The number of days required for spring is longer than that of autumn, and the fruit shape is also larger and the flesh color is also darker. In the low temperature period, in order to prevent cold, it is advisable to use tunnel sheds for heat preservation and seedling cultivation. When 1-2 true leaves are unfolded, they can be planted in the field. 2. Seed disinfection and germination sowing: In order to prevent the seeds from being attached with pathogens that affect seed germination and the spread of diseases and pests, it is best to disinfect the seeds before sowing. Watermelon seeds are generally soaked in 100 times formalin solution for 30 minutes and then picked up, and the residual pesticides can be washed with clean water. In order to increase the germination rate of seeds and make them germinate quickly and uniformly, save the amount of seeds, avoid rodent damage, and avoid missing plants, germination sowing is generally used. Especially in the low temperature period, germination sowing is more suitable; the germination temperature is best to use a constant temperature of 28-300C. Watermelon seeds are photophobic, so the light should be blocked during germination. When the young sprouts emerge from the seed shell, they should be sown in hole trays or field planting holes, with the young sprouts pointing vertically downward. When raising seedlings, sow 1 seed for germination in each hole. When direct seeding, sow 2-3 seeds for germination in each hole. Cover with soil about 1.5 cm thick and water after sowing.
