3. Specific gravity method Generally, the proportion of ripe watermelons is in between, which is greater than this number.

In general, take a pat and you know if he is raw, or cooked? If you are together, you will see the color of it. and size.

One. Watermelon originated in the Sahara Desert region of Africa, and then gradually moved north to Egypt and spread to Iran, so watermelon, like tomatoes and broccoli, all have a West character, and watermelons are cultivated in the north and south of China. The melon is round or oval, and the skin color is dark green, green, white or green with snake patterns.

The skull is juicy and sweet, with a deep red, light red, yellow, or white color. The types of watermelons include Jingxin series, Jinzhong Guanlong, Shoushan, New Ruby, Red Jade, Black Beauty, Seedless Watermelon, Flower Skin Watermelon, etc. Among them, the unicorn melon with thin skin and thick flesh is the most popular among everyone, and the sweet and crisp taste is incomparable to other watermelon varieties.

First look at the watermelon to see if there are white hairs around the roots, if there is raw, if it is smooth, it is ripe.

Tricks for picking watermelons: "pinch, play, check, touch, look". Pinch: Pinch the skin of the melon with your fingernails, the cooked skin is crispy and juicy, so it is easy to pinch in, and the skin of the raw melon is harder and difficult to pinch.

Bullet: Use the index finger or middle finger to hit the watermelon, if the sound is muddy and heavy, the sound of "bang bang" must be ripe melon; For example, it is raw melon that makes a crisp sound of "dang"; The "poof" sound is an overripe watermelon.

Ripe watermelons are lighter than unripe watermelons, but watermelons that are too light may be overripe or rotten. The watermelon with a pronounced heaviness is definitely a raw melon.

Touch: Ripe melons that feel hard and smooth to the touch, raw melons that are not smooth and sticky.

Look: The skin of the melon is smooth and bright, the dark green pattern is clear, there is no white hair, and the bottom of the melon is orange. The color of the melon skin is not bright, the texture is not clear, the melon skin has fine hairs, and the melon handle is blue-green and has fine hairs. The one with the withered stalk is the dead seedling.

Observations are made through indicators such as appearance color, bottom spots, pedicle condition, percussion sound, and flesh color and texture.

To judge whether the watermelon in the field is ripe, you can start with the appearance. Ripe watermelons usually have a bright and vivid skin color, such as dark green or yellow-green, rather than light green. The skin should be smooth and even, with obvious bumps or blemishes in the finches.

In addition, the bottom spots of the watermelon can be observed. Ripe watermelons will have yellow or cream-colored spots on the bottom, which refers to where the guati area touches the ground. If the spot at the bottom of the fruit is distinctly yellow or creamy, then the watermelon is likely ripe.

In addition to appearance, there are other ways to tell if the watermelon is ripe. Try twisting the pedicle of the watermelon, if the pedicle is easily twisted and the part that joins the fruit is dry or cracked, then this could be a sign of ripeness. In addition, you can gently tap the surface of the watermelon and listen to the sound.

Ripe watermelons usually make a dull sound, while unripe watermelons have a crisp sound. Finally, if you have the chance, you can cut a small piece of watermelon pulp to observe.

Precautions for watermelon planting

The watermelon in the puffing period needs enough water to grow, but the irrigation must be appropriate and even, you can irrigate once every 5-7 days, to keep the soil dry and wet, if the soil is dry and then wet, it is easy to crack the melon, so it is important to water with small water to keep the humidity uniform. Please note that if drip or sprinkler irrigation is used, it can be irrigated according to the actual conditions in the shed.

When planting watermelons, the fertilization is too blind, the amount of fertilizer exceeds the standard, and the rotten brother cannot achieve reasonable fertilization, usually the potassium fertilizer is not enough, and the nitrogen fertilizer exceeds the standard. In addition, when fertilizing, the amount of fast-acting fertilizer is excessive, the amount of organic fertilizer is insufficient or organic fertilizer is not used at all, so that after planting for several years, the phosphorus content in the soil exceeds the standard, and the nitrogen and potassium content is insufficient.

1. Morphological observation method: Under normal circumstances, the yellowing or withering of the tendrils of the knot knot node and its front and back segments indicates that the melon has matured. In addition, after the melon is ripe, the skin of the melon will show the unique luster and color of this product; After ripening, the skin of the melon is shiny, the pattern is clear, and the thin tendons of the epidermis are protruding; Ripe melons, whose skin sticks to the ground, dark green-skinned varieties turn yellow, and light-skinned varieties turn greenish-white.

The base of the ripe melon stalk is hairy and clean.

2. Listening to the sound method: when you tap the melon skin with your hand, the one that makes a "bang" low voiced sound is a ripe melon, and the one that makes a crisp sound of "dong dong" is an unripe melon. But sometimes the skin of the melon is more cautious or the dead gourd, although it is not ripe, it will also make a "bang" sound when knocked.

Melons that are listed earlier in the spring are prone to this situation, and the search is late.

1. Look at the ground print.

The "ground print" is the place where the watermelon comes into contact with the ground, and as the watermelon gradually matures, the color of the ground print becomes darker. If it is white, it is not ripe.

2. Look at the melon handle.

The stalk of a freshly ripe watermelon is green, the stalk is dry, it may be a dieffa, if it is dark brown and the hairs are falling off, it may have been picked prematurely and not ripe.

3. Look at the lines.

These brown lines are caused by bee pollination, and the more pollination, the sweeter the watermelon becomes. The texture should be deep and clear, and the surface should be light and slippery.

4. Calculation method.

Count the number of days after flowering or the number of accumulated temperatures. Under certain climatic conditions, the number of days from the opening of female flowers to the ripening of fruits of a variety is basically fixed, and the accumulated temperature required is also the same.

It takes 25 to 26 days from flowering to maturity for extra-early maturing varieties, and the accumulated temperature is about 700. 30 35 days for early and medium ripening varieties, and the required accumulated temperature is 800 900; Late-maturing varieties are more than 40 days old, and the required accumulated temperature is more than 1000.

The accumulated temperature is calculated by adding up the average temperature of each day, or by multiplying the average daily temperature by the number of days using meteorological data. The higher the average daily temperature, the fewer days from flowering to maturity. Melons that bear fruit at different times on the same watermelon plant are early to mid-to-mid, and the number of days it takes to ripen is also different.

5. Hand measurement method.

Flick the melon with your fingers or pat or touch the melon with the palm of your hand. The dullness of the melon is a ripe melon. It produces a crisp and crisp sound for raw melon.

When you touch the skin of the melon with your hands, the one that has a slippery feeling is the cooked melon, and the one that is astringent is the raw melon. One hand to hold the melon, one hand on the top of the melon gently patting, such as the palm of the melon slightly trembling, the melon makes a loud sound is a ripe melon, such as the hand of the melon does not feel trembling, the sound of the sound is raw melon. Squeeze both ends of the fruit with both hands at the same time, put it in your ear and listen, if there is a hissing melon cracking sound, it is a ripe melon.

6.It was determined by a non-damaging melon and fruit tester.

1. Weigh the weight: The higher the ripeness of the watermelon, the lighter its weight. Generally, watermelons of the same size are better for light ones, and raw melons for those that are too heavy.

2. Look at the melon navel: Generally speaking, after the watermelon is ripe, the umbilicus and the fruit pedicle part of the fruit are contracted, and the color of the downward side of the fruit is white and yellow.

3. Look at the fruit stalk: some watermelons still have fruit stalks when they are picked, if the fruit stalk is turquoise, it means that it has just been picked not long ago, and the fruit stalk is yellow, which means that it is caused by bad vines or picked for too long, and this watermelon tastes bad.

4. Listen to the sound: Many people will take a pat when buying watermelon, in fact, it is to judge whether the watermelon is ripe or not by the sound. Knock the watermelon with your hand and hear the dull sound, which means that the melon is ripe, and hear the sound more crisp, which means that it is not ripe.
