Look at which parts of the radish are sweet and full of water without chaff?

White radish should be chosen with a heavy proportion, a heavier weight, and a heavy weight in the hand. If you master this well, you can avoid buying hollow radishes such as bran radishes and fleshy chrysanthemum heart-shaped radishes.

Look at the tail of the radish, you can see that the radish is not chaff, sweet, and has a lot of moisture, you can also look at the radish leaves, if the radish leaves are rotten, the radish will basically have a bran heart.

If his head is very green, it proves that it is very fresh, and then it is also very sweet, very juicy, and the food is very delicious.

The white radish body is slender, ** smooth, and the weight is larger, you can break the radish tassel to take a look, if there is no moisture in it, it means that the radish bran is out; Looking at the radish whiskers, the root of the radish should be straight, thin and long, which means that the radish is very fresh!

Bran carrots.

It is a phenomenon in which cylindrical holes grow longitudinally on the fleshy roots in the late growth stage of radish.

When the number of leaves, the size of the leaves, the weight of the roots and the size of the radish increase the fastest, it is often the period when the chaff begins to form.

During the rapid expansion of the fleshy roots of radish, the fleshy roots are far away from the conductive tissues, and due to the rapid expansion and growth of the cells, it is becoming more and more difficult to transport water and nutrients here, so that the parenchyma tissues here are in a "starvation state".

First of all, it is manifested in the disappearance of sugar in the large cells of the parenchyma, and then the pectin of the cell wall and the mesogelatin layer gradually dissolves and disappears, and the parenchyma cells are separated from each other, and the gap between them gradually expands, bubbles occur, and finally a hollow state is formed.

No matter how cheap the radish is, as long as there are these 4 situations, they are all chaff, don't buy them blindly.

When the radish is too old, the internal moisture is insufficient, and the flesh is soft and dehydrated, like cotton.

Those who have lost water are like cotton in the middle, and they are no longer nutritious.

1. Variety selectionFor areas with a high incidence of radish bran and hollow core, medium radish varieties with fleshy roots should be closely arranged before sowing radish and radish varieties with long growth cycles, and at the same time, try to avoid planting extremely early maturing or early maturing radish varieties or large radish skin varieties.

2. Fertilization management uses boron fertilizer and other trace elements in the fertilization process, which can prevent the bran core caused by the lack of boron fertilizer, and the use of 5 kg of borax on the bottom fertilizer should be used with organic fertilizer on top dressing, and the borax or boric acid solution can be sprayed during the expansion period, sprayed once every 5 days or so, sprayed 3 4 times in a row, and the effect is better.

3. Planting temperature radish planting, try to avoid planting in the case of high temperature, you can wait for the temperature to drop to about 20-25 degrees before radish planting, so that when the radish fleshy roots begin to expand and develop, the temperature can almost drop to about 18-20 degrees, and the temperature in this range is most conducive to the expansion and development of radish fleshy roots.

4. Scientific watering radish in the early stage of growth of the seedling watering should keep the soil moderately moist, in the radish into the rosette period to properly control the water squatting seedlings, until the radish leaves become dark green, after the completion of the squatting seedlings and then watering 1 permeability, at this time in the radish fleshy root formation, expansion to harvest or so 10 days before the harvest should keep the soil always moist, so that can control the above-ground stems and leaves vigorous, robust seedlings, but also can promote the smooth expansion and development of the underground fleshy roots of the radish, so as to ensure high yield and excellent harvest in the later stage.

5. In the management of the radish growth period, if the radish grows too vigorously, in order to avoid the phenomenon of "hollow" or "chaff", it is recommended that we spray 1-2 times continuously according to the dosage of 15 grams of paclobutrazol per mu to control the growth of radish in a timely manner, and the interval between the spraying of drugs to control the growth is about 7-10 days. In addition, according to the actual needs, 30-40 days after the radish is sown and about 15 days before harvesting, it can be sprayed with a concentration of 100 mg kg of naphthalene acetic acid once. Spraying naphthalene acetic acid on radish can effectively prevent the occurrence of bran and hollow on radish.

I think the cause of radish bran is the incompatibility of water, soil and fertilizer, light and temperature. Base hail

1. Water imbalance, in the peak growth period of fleshy roots, the cells expand rapidly, if the temperature is too high, the plant respiration and transpiration are vigorous, the water consumption is too large, and some parenchyma cells in the fleshy roots will lack the nutrients and water with the front and be in a state of starvation, and there will be gaps between the cells, so there will be a chaff heart.

2. Soil and fertilizer, the conditions are not suitable for excessive fertilization, especially too much nitrogen fertilizer, radish grows vigorously, the proportion of the aboveground part and the underground part is out of balance, the aboveground part grows rapidly, consumes more nutrients, and can not have a large amount of photosynthetic products to the fleshy roots.

3. Light and temperature, if the temperature is high day and night, especially at night, a large amount of assimilation products will be consumed, which is easy to cause chaff. Short eye exposure conditions are conducive to the formation of fleshy roots, and some varieties tend to have bran core phenomenon under long sunlight. During the formation of fleshy roots, if the light is insufficient, the assimilates are reduced, the growth of stems and leaves is restricted, and the bran core phenomenon is also prone to occur.

Radish introduction

It is a biennial or annual herbaceous plant of the cruciferous family and the genus radish, which can reach a height of 100 cm; Straight fleshy, oblong, spherical or conical, green, white or red skin; basal leaves and lower stems and leaves large pinnately semilobed, apical lobes ovate, oblong, obtusely toothed, sparsely coarsely hairy, racemes apical and axillary; The flowers are white or pink, the sepals are oblong, and the petals are obovate.

First of all, look at the new leaves that grow in the middle of the head, which will grow later, and this kind of leaf will absorb the water in the radish, and the radish will lose its moisture and become bran or hollow. Second, the weight is the best reflection of the amount of moisture inside the radish, pick up the radish in your hand and shake it, and the heavy feel is enough water, that is, fresh. If the amount is not enough, it feels very light, the radish is not fresh, the internal moisture is insufficient, and it may be chaff or hollow.

Take a look at the skin of the radish, the skin of the radish should be smooth. Second, look at the roots of the radish, the radish is sweet and watery, and the root has only one large taproot. And it's evenly distributed. Three look at the radish tassels. Fresh turnips, turnip tassels will not grow new shoots.

In fact, just look at the center of the radish, it is generally relatively tender, and then its bottom will crack, which proves that it has a lot of sugar and sugar, and the flesh is juicy, very delicious.

Forgive me for not hearing of it, I have seen the kind of radish that has been soaked in water or left for a long time, the color is yellow, the meridians are thick, there are cracks, the taste is not brittle, and the water is less

Selection and processing of turnips.

Radish is also known as radish white, cabbage, rasp, etc. Radish is rich in carbohydrates, fiber, vitamin C and minerals such as calcium, phosphorus, potassium, iron, etc., and is rich in nutrients. Radish also has the effect of promoting metabolism and increasing appetite, and has a certain effect on indigestion, stomach fullness, cough and phlegm, chest tightness and asthma, cold and flu.

The shape of radish is long, round, oblate, oval, spindle, cone, etc., and the skin color is red, green, white, purple, etc. In the selection of fresh radishes with uniform size, no lesions and no damage, should be selected; The skin of the radish is delicate and smooth, and the back of the finger is flicked to touch its waist, and the voice is heavy and strong, and the voice is not chaff, and if the voice is muddy, it is mostly chaff.

Different parts of radish contain different nutrients, so different ways of eating should be taken to maximize the nutrients contained in radishes

From the top of the radish to 3-5 cm is the first section, this section has the most vitamin C content, but the texture is a little hard, suitable for shredding, strips, quick cooking, can also be shredded to cook soup, used with mutton to make filling, excellent taste;

The middle section of the radish has more sugar content, the texture is crisp and tender, it can be diced to make a salad, it can be shredded and mixed with sugar and vinegar, and it is also very delicious to stir-fry;

From the middle section to the tail section, the radish has more amylase and mustard oil and other substances, some spicy taste, which can help digestion and increase appetite, and can be used for pickling; If peeled and eaten raw, it is the best choice for diabetics to replace fruits; Cooking can be stewed, fried, and souped.

Radish bran heart reason:

1. In the process of harvesting, storage and transportation, it causes cracks, cracks and other wounds, which enhances the respiration effect, and causes radish bran heart due to excessive consumption of nourishment and feast;

2. The temperature of the radish storage environment is too high, and the suitable temperature for radish storage is 1 to 3 degrees Celsius, and it is easy to germinate and grow when it exceeds 3 degrees Celsius, resulting in radish chaff;

3. The radish storage environment is too dry, the ideal air humidity for radish storage is between 9% and 95%, and when it is less than 90%, the radish is constantly dehydrated to make the tissue soft, which eventually leads to the radish chaff;

Measures to prevent radish bran from becoming aggressive:

1. In the process of harvesting and transporting radish, try to minimize mechanical damage such as broken skin and fracture of radish, remove the stem plate before storing radish, place it in a cool and clean place to prevent wind, sun and frost, and store it when the temperature in the cellar and warehouse drops below 4 degrees Celsius;

2. When the radish is in storage, first spread a layer of 8 to 9 cm thick wet sand at the bottom of the cellar, check whether the radish stem plate is cleaned, remove the radish with wounds, and then place a layer of radish covered with a layer of wet sand, and place it in turn, pay attention to ventilation, temperature control and moisturizing, so that the radish storage environment is best kept at a temperature of 2 degrees Celsius, and the humidity is between 90% and 95%.
