When planting radish, how to prevent radish hollowing?

Although radish is a crop with heavy base fertilizer and light top dressing, the application of boron fertilizer during the peak growth period of radish can effectively reduce the hollow probability of radish, in addition, the application of boron fertilizer can promote the photosynthesis of radish and improve the resistance of radish. It is worth noting that when applying top dressing, the growth period of radish is light and short, with only two to three months of growth time. Our ordinary households generally plant radishes in late summer and early autumn, and harvest them in late autumn and early winter.

If planted too early, it is easy to cause radish to sprout prematurely due to high temperature in the early stage, radish selection, sowing time, planting, water and fertilizer management, harvesting, storage, etc., any link in these processes, if there are some improper behaviors will cause radish hollow.

Radish is an annual herbaceous plant of the genus Radish in the family Cruciferaceae, which is twenty to one hundred centimeters long and has a green or red skin. As a wild species that grows on the warm coasts of Asia and Europe, it was widely popular as soon as it was transmitted to China, especially in the countryside in the seventies and eighties. In general, the growth of the aboveground part and the growth of the underground part of the radish in the growth process are out of balance, and the radish hollow will appear, and the loss of balance is often related to the variety of radish, soil, fresh white radish water is sufficient, and the radish is formed and expanded in the soil layer, and the water is not enough to expand the radish fruit in the above-ground plant and soil layer, and there will be a certain degree of hollow phenomenon.

Some radish varieties have large fleshy root parenchyma cells, and the fleshy root density is very poor, and this kind of radish varieties are very prone to hollow conditions in the process of growth. As a result, many regions have stopped cultivating such radish varieties. The principle of topdressing as a supplement, pay attention to the rational combination of nitrogen, phosphorus and potassium, scientific fertilization, varieties with short growth period, mainly base fertilizer, varieties with long growth period should be topdressed in stages and early, and master the principle of "light topdressing in the true leaf stage and heavy topdressing in the fleshy expansion period".

When planting, we must choose high-quality soil, and then also choose high-quality varieties, during the planting period, we should also add more water, eat more = nitrogen fertilizer and potassium fertilizer, and also do a good job in the management of weeds in the field during planting, and do a good job in the prevention and control of diseases and pests in advance, so that the radish planted will definitely not be hollow, and its yield will definitely be particularly good.

Regular pastoral management, deep soiling, regular water and fertilizer management, regular use of drugs to remove pests, supplemental sunlight and so on can be well prevented.

Spray some pesticides when planting radish, spray some pesticides after planting radish, and then spray pesticides on time according to the growth cycle of radish, water more and fertilize more, and pay attention to the disaster of insects.

First of all, we must choose a good variety, to the kind of fleshy root parenchyma cell variety, can effectively prevent the radish hollow, and then it is necessary to plant the radish in the clay soil so that the radish can grow healthier, and then it is necessary to water the radish field every day, and there is a fertilizer must grasp the material, must not apply too much, if you eat too much, it will also lead to the hollow of the radish, and there is a regular check of the state of the radish, if there are germs or pests, Be sure to spray pesticides in time to prevent and control them, which can not only make the radish grow particularly healthy, but also prevent symptoms such as hollowing of the radish.

The heart of the white radish becomes empty, indicating that it is the chaff heart, which is a common problem encountered in planting, generally we will encounter the bran heart after storing the white radish for a long time after the lack of water, but the lack of water in the planting will also encounter the bran heart, so it is needed firstEnsure the moisture of the land。SecondlyIt is the allocation of temperature, the choice of the variety.

1. Maintain sufficient water and fertilizer

The hollowness of radish bran core is closely related to soil moisture, and the lack of water first leads to the sponge of core fibers. Secondly, the lack of water allows respiration to work.

strengthened, the internal structure will naturally change.

Second, the selection of varieties in the high temperature season

There are many varieties of radish, generally we commonly have ivory radish, green radish, purple radish, heart radish, cherry radish.

Carrots, etc. Among these radish varieties, those with small body size, tight flesh and slow growth rate are not easy to be hollow, on the contrary, those with larger body size and rapid root growth will be prone to hollowing. In addition, in the warm season, the temperature is high, and the larger radish is not suitable for planting, which will make the roots grow more quickly, and the high temperature on the surface makes the radish hollow more serious.

Therefore, the high temperature season is only suitable for planting small radishes such as cherry radish.

3. Harvest time

The most suitable time for harvesting radish is when the leaves turn from dark blue to light and slightly yellow, which affects the yield too early, and will expand too late, the roots will age, and the absorption of water will slow down, and it will naturally be chaff and hollow. <>

Fourth, the storage environment

In general, at a reasonable time in a reasonable season, the harvested radishes are very watery and spicy.

Moderate, but once stored for a period of time, it will become chaff, which has a lot to do with the humidity and temperature of the storage environment, first of all, the environment in which we store it can not be at least 10 degrees Celsius, if the temperature is high, the radish will remain active and continue to grow, and it will naturally grow old and become chaff, and secondly, it is necessary to pay attention to the use of snakeskin bags.

Store properly sealed and do not allow excessive moisture to escape. All are required within 20 to 30 days**. <>

In the process of planting, white radish will have similar in addition to hollowDeformed, cracked roots and even black skin, black heartThese are also related to the hardness of the soil, the environment, too much improper fertilizer, uneven moisture, etc.

1.Before planting, it is necessary to plough the soil thoroughly when ploughing the land.

2.Reduces or weakens the content of urea.

of organic fertilizer, comprehensive and deep cleaning of the soil from stones, rubble.

3.Avoid prolonged droughts and sudden water injections. This is one of the most important things to avoid root cracking.

4.Excessive use of human manure, animal manure fertilization, and excessive microorganisms are high oxygen consumption, and soil hypoxia is the key factor causing black skin and black heart. The land is thoroughly turned over before planting.

5.Relax the soil regularly to ensure sufficient oxygen content and avoid black hearts and black skins.

White radish should be kept reasonably nutritious, and some good quality varieties should also be taken, so that the white radish is very delicious, and it will not be hollow.

If you want to avoid hollowing, you should water and fertilize in time, and you should also do a good job in the management of water and fertilizer, and you should also spray pesticides in time to avoid the harm of insect pests, and you also need to ensure sufficient light and temperature vision.

First of all, when fertilizing, a small amount of fertilizer should be applied, not too much and not too little. Sowing seeds at the right time, with the right amount of watering.

In the process of planting, it is necessary to pay attention to the right time of watering and fertilization, and also pay attention to the balance of nutrients to avoid this situation.

Living in the countryside, we eat the radishes every year are home-grown. Villagers are often troubled by the hollowness of radishes, which not only reduces the overall yield and quality of radishes, but also causes the meat to be dry and rough, which makes it difficult to taste and sell. How can you make the radish not hollow, only the personal summary has the following aspects, which should reduce the hollowing phenomenon of the radish.

Hollowing of radish is a physiological phenomenon, not a disease, which is mainly manifested as lesions and even cavities in the center of the fleshy roots of radish. In the early stage, it can be found that the fleshy roots are ring-shaped or brown lesions, and the edible value is reduced, which seriously affects the economic benefits. The problem of radish varieties.

Large radishes with loose flesh are more likely to cause hollowing than delicate ones. Because the fiber of large radish with loose flesh will also be more loose, it is normal for the fiber to crack and hollow when growing.

Caused by the inappropriate planting density of radishes. Some people think that if the radish is planted loosely, the radish will grow very large. Doing so will increase the chance of the radish being hollow.

Finally, there is the hollowing of the radish due to improper moisture and fertilizer. When planting radish, although it is not picky about water and fertilizer, it is also necessary to water and fertilize reasonably, and insufficient fertilizer or too much fertilizer will cause the hollow of the radish if it is too dry or wet.

The hollowness of radish may be caused by the variety, some small radishes with dense flesh grow slowly, and when the growth of the leaves is balanced, it is not easy to hollow; Large radishes, on the other hand, with sparse flesh, grow quickly, and the growth of roots far exceeds the growth of leaves, and they are prone to hollowing. In addition, improper sowing time will also cause hollowing, sowing time too early, radish growth temperature is too high, resulting in growth stagnation, consumption of a lot of nutrients, easy hollowing. There are great differences between hollow varieties of radish, which can be roughly divided into three varieties: large, medium and small.

Large varieties penetrate the soil deeply, the flesh is relatively loose, the fleshy root expands faster, and when it is greater than the growth rate of the leaves, it is easy to hollow. Small and medium-sized varieties have shallow soil, relatively fine flesh, slower growth rate of fleshy roots, more balanced growth of roots and leaves, and are not easy to hollow.

You can apply more fertilizer to the land in the early stage of planting radish, and then also apply some fertilizer to the radish during the planting process.

1. Pay attention to scientific and reasonable watering: the requirements for soil moisture content in the growth and development stage of radish are generally 60% 80%, especially in the swelling period of radish fleshy roots, insufficient soil water supply or drought and waterlogging, it is easy to cause hollowness, so a balanced water supply should be maintained, when the soil water content is lower than the above requirements, it is necessary to water properly to keep the soil dry and wet.

2. Scientific application of boron fertilizer: boron fertilizer can promote the growth of radish hearts. From the radish seedlings grow 2 or 3 true leaves to about half a month before harvest, spray boron fertilizer every 20 days or so, 150 grams of borax or 100 grams of boric acid per mu each time, first dissolve 60 75 kg of water with a small amount of warm water, spray evenly, and the spraying time is appropriate in the evening.

Good quality varieties should be selected before planting, and irrigation and fertilization should be carried out in a timely manner to avoid such hollow states and should be harvested in time.

Be sure to fertilize more, don't let the radish be malnourished, and you must pay attention to insect pest control and pay attention to protecting the loose and breathable roots of the roots.

Harvest at the right time. When the radish grows, it must be harvested, otherwise it is easy to hollow.

Improper selection of varieties, excessive growth of above-ground stems and leaves, lack of water during the expansion period, lack of nutrients (such as potassium deficiency, boron deficiency), damage during harvesting, high temperature and humidity in the storage environment, etc., which can easily cause radish to appear "chaff heart" and "hollow" due to insufficient organic nutrient transport and accumulation when the underground fleshy root swells, or "bran heart" and "hollow core" due to excessive loss of water and nutrients in the body during the harvest and storage period.

If the radish is hollow, it is most likely caused by insufficient water during the growing season. Therefore, in the process of growing radish, enough water should be given so that the fruit can be full.

It is caused by being too ripe, and when the radish is ripe, it will be hollow.

Water and fertilizer related: water and fertilizer ** uneven or drought and waterlogging and other phenomena, it is easy to crack the phenomenon, especially when the fleshy stem is mature, the outer skin has been lignified, at this time, a large amount of watering will make the fleshy stem suddenly expand, the epidermis can not be expanded with it, especially during the succulent stem expansion period, pay attention to watering evenly, keep the soil moist, avoid flood irrigation, do not accumulate water. If soil compaction is found, it is necessary to carry out tillage in time to ensure soil drainage and air permeability.

<> pests and diseases are inevitable problems encountered in many planting processes, and they are also the root cause of damage to farmers' interests. After the occurrence of pests and diseases, proper control can often have better results, but if the control is not timely, it may lead to the breeding of pests and diseasesSudden flooding: During the swelling period of young shoots on the ground of lettuce, the early stage has been relatively dry, and the amount of watering is insufficient.

If it rains heavily suddenly, or if it is watered a lot, the young stem of lettuce will expand rapidly, and the internal and external growth will be inconsistent, and there will be a hollow problem.

Bottom fertilizer: Before lettuce planting, base fertilizer should be applied to the land to ensure the nutrients needed for the growth of lettuce seedlings. The base fertilizer should be mainly farmhouse fertilizer, with compound fertilizer and nitrogen fertilizer, about 4000kg fertilizer per mu.

The lack of boron, calcium and other trace elements in the plant will affect the formation of biological enzymes and the thin and brittle cell wall in lettuce, resulting in poor plant stress resistance and easy to cause hollowness.

1. During the growth of lettuce, drought and flood are uneven, and the sudden flood irrigation causes the growth of internal and external tissues to be unsynchronized, forming a hollow. 2. When nitrogen fertilizer is applied excessively, phosphorus and potassium are insufficient, it will cause excessive nutrients, insufficient dry matter accumulation in the plant, and it is easy to produce hollowness. Boron can promote the growth and development of plant roots, and plays an extremely important role in the process of transporting carbohydrates, and carbohydrates are the main substances that fill the fleshy stems of lettuce.
