Watermelon Baidu knowledge

Watermelon (Citrullus lanatus, English: Watermelon) belongs to Cucurbitaceae and is native to Africa.

Watermelon is a dicotyledonous flowering plant, which is shaped like a vine and has feathery leaves. The fruit it bears is a fake fruit, which belongs to what botanists call a fake berry.

Fruit skin is smooth, green or yellow with patterns, and pulp is juicy, red or yellow (rare white). Morphological characteristics Watermelon is an annual vine herb.

The fruit is crisp, sweet and juicy, rich in mineral salts and vitamins, and is the main fruit in summer. Watermelon can clear away heat and relieve summer-heat, and has an auxiliary effect on treating nephritis, diabetes and cystitis.

Peel can be preserved, preserved, jam and feed. The oil content of seeds is as high as 50%, which can be used to extract oil, fry food or make pastry ingredients.

Characteristics: Watermelon has a main root system with a depth of more than 1 m, and the root groups are mainly distributed in the root layer of 20 cm-30 cm. The roots are slender and easily broken, with weak regeneration ability and poor transplant tolerance. The stem of the seedling stands upright, elongates after 4-5 nodes, grows prostrate after 5-6 leaves, has strong branching ability, and can form 3-4 levels of lateral branches.

Leaves alternate, deeply divided, shallowly divided and entire. The dioecious flowers are the same plant, the male flowers are in the 3 rd to 5 th nodes of the main stem, and the female flowers are in the 5 th to 7 th nodes. A few bisexual flowers can appear at the flowering stage.

Corolla yellow. The ovary is below and the placenta is the lateral membrane.

Both male and female flowers have nectaries, and the flowers are insect-borne flowers, which open in the morning and close in the afternoon. Fruits are spherical, oval, oval, cylindrical and so on.

The surface of the fruit is smooth or ribbed, and the epidermis is green-white, green, dark green, dark green and black, with fine meshes or stripes in between. The pulp is milky white, light yellow, dark yellow, light red, bright red and other colors.

Meat is divided into meat and mortar. Seeds flat, ovoid or oblong, smooth or cracked.

The seed coat is white, light brown, brown, black or brown, monochrome or variegated. 1000-grain weight 100g ~ 150g, middle grain type 40g ~ 60g, small grain type 20g ~ 25g.

The type of melon is 145g ~ 200g. Watermelon watermelon fruit is the main fruit in summer.

Mature fruit contains a lot of water, and the sugar content of pulp is generally 5~ 12%, including glucose, fructose and sucrose. The sweetness increased with the increase of sucrose in the late mature stage.

Without starch, the sweetness will be reduced due to the hydrolysis of disaccharide into monosaccharide during storage. Melon seeds can be used as tea, and melon skin can be processed into watermelon sauce.

Chinese medicine uses melon juice and peel as medicine, which can clear away heat and relieve summer heat. It can be called the king of melons. It was introduced from the western regions in the Han Dynasty, so it was called watermelon.

Watermelon also belongs to the genus Cucurbitaceae, which is native to Africa. At present, except for a few remote and cold areas, it is planted all over the country, and the fruit is sweet and cold. Watermelon is a typical fruit and the main fruit in summer. As long as there is frozen watermelon in hot summer or hot tropical night, it will have the effect of relieving summer heat.

Variety: Watermelon can be divided into three categories according to different uses: ordinary watermelon, melon seed melon and small watermelon. Watermelon-also known as water melon, cold melon and summer melon-was called "watermelon" because it was introduced from the western regions in the Han Dynasty. It tastes sweet and juicy, refreshing and thirst-quenching. It is a good fruit in midsummer, which can not only dispel summer heat and quench thirst, but also has a good diuretic effect, so it is called "natural white tiger soup". Watermelon contains almost all kinds of nutrients needed by human body except fat and cholesterol. This is a natural white tiger soup.

Can be used for treating edema, dysuria, fever, diabetes, red eye and swelling and pain. Growth process of watermelon: Watermelon is an annual vine crop, and there is a growth cycle from seed to seed, and the whole process generally takes 100- 120 days.

The whole process has obvious stages, with different morphogenesis, physiological functions and environmental requirements, and each stage is interrelated and influenced each other. According to the characteristics of different growth stages of watermelon, it can be divided into four stages: germination stage, seedling stage, craning stage and fruiting stage.

1. The germination period generally takes 7- 13 days from sowing to the appearance of the first true leaf. When the seeds germinate, the water absorption is 60%-70% of the weight of the seeds.

The optimum temperature for germination is 28-30℃. When the temperature is lower than 25℃, the germination period is prolonged, the germination rate is reduced and the seedlings are thin.

When the temperature exceeds 35℃, the germination rate is obviously reduced and the seedlings grow thin. Variable temperature treatment can shorten germination period, improve germination rate and seedling quality.

Cold bed and hotbed are used to raise seedlings in production. When about 70% of the seedlings are unearthed, they should be cooled immediately. The daytime temperature is 22-25℃, and at night 13- 15℃, and the ground temperature is kept at 18-20℃ to avoid the formation of tall seedlings. Second, the seedling stage starts from 1 true leaves to 5-6 true leaves, which is called the seedling stage or clumping stage of watermelon, and generally takes about 30 days.

During this period, the internodes were short and erect, and the leaves differentiated rapidly, but the leaf growth and leaf area expanded slowly, while the roots and new organs differentiated vigorously. At the top of seedling stage, 8-9 completely differentiated leaflets and 2-3 basal parts of Yuan Ye appeared, and the flowers differentiated. The method of loosening soil and heating should be adopted in production to promote root growth and female flower differentiation.

Third, the vine-pulling stage is the main period of vegetative growth, which marks the end of seedling stage. It takes about 18 days for a plant to bloom from clumping to the first female flower, and then a female flower will bloom every 4 days.

In the vine-pulling stage, long vines have long leaves, the internodes are rapidly elongated, the plants change from upright to creeping, and the leaves and leaf areas are rapidly expanded. Generally, a big leaf appears in 4-5 days. Plants grow vigorously, providing sufficient nutrients for the development of flowers, while the root system gradually slows down from vigorous growth to the end of vine extension, and the root system development is basically completed.

In production, according to the growth characteristics of vines, vines and leaves should be fully grown in the early stage to lay a good foundation for later flowering and fruiting, and cultivation management should focus on promotion. When the vines grow to about 30 cm, cake fertilizer or compound fertilizer should be applied to promote the growth of vines. On the one hand, vines and leaves should continue to grow vigorously in the late stage of vine pulling, on the other hand, nutrition should be properly prevented from growing too fast to avoid delaying or affecting flowering and fruit setting. Cultivation is mainly controlled, and measures such as pruning, vine pressing, fertilizer control and water control are taken to prevent melons from growing wildly.

4. The fruiting period takes about 25-40 days from the opening of female flowers to the complete maturity of fruits. According to the different morphological changes and growth characteristics of fruits, the fruiting period is divided into prophase, metaphase and anaphase. 1, prophase.

It takes about 4-6 days from the opening of female flowers to the depilation of fruit, which is also called fruit-setting period. After the female flower opens, the ovary begins to swell, the villi on the surface of the melon gradually become sparse, and the whole fruit also appears shiny. At this time, the stems and leaves continue to grow vigorously, and the young melons grow slowly, which is the most intense stage for the two to compete for nutrients, the turning stage from vegetative growth to reproductive growth, and the critical period for deciding whether to set fruit.

Production should focus on prevention and control, timely pruning vines, proper control of fertilizer and water, control of vine leaf growth, artificial pollination and promotion of fruit setting. 2. medium term.

It takes about 18-24 days for the fruit to expand from molting to fruit setting. At this time, the fruit expands rapidly, so a lot of substances are transported into the fruit, and the growth of vines and leaves begins to slow down, which is the key period to determine the size and yield of melons.

In production, swollen melon fertilizer should be applied again, and fertilizer and water management should be strengthened to expand and maintain leaf area, improve photosynthesis and prevent water shortage and fertilization. At the same time, keep the fruit and pick the core properly, so that the nutrients can be distributed reasonably in the stems, leaves and fruits.

You can also topdressing outside the roots to prevent premature aging. 3. Late stage.

It takes about 7- 10 days from fruit setting to full maturity. At this time, the fruit is basically shaped, the growth is reduced, but the internal substances of the fruit change, the sugar conversion, especially the sucrose content increases rapidly, and the sweetness of watermelon increases. At the same time, the color of pulp gradually darkens and the peel becomes hard and smooth.
