Causes and control methods of hollow radish

Radish is a common vegetable, but in the process of vegetable farmers are very distressed is the radish hollow, hollow radish nutritional value is extremely low, but also lead to low yield, the most important thing is not sold out, resulting in losses. So what is the cause of the radish hollow? How to prevent it? Let's take a look at the detailed introduction of pro-agricultural network together.

1. Variety and sowing date

The hollowness of radish may be caused by variety. Some small radishes with dense meat grow slowly, and when they grow in balance with leaves, they are not easy to hollow; while large radishes with sparse meat grow rapidly, and their roots grow far more than the growth of leaves, and they are easy to hollow. In addition, improper sowing time will also cause hollow, sowing time is too early, radish growth temperature is too high, leading to growth stagnation, consumption of a lot of nutrients, easy to hollow.

Control methods: From the above content, it can be seen that selecting small radishes with dense meat can reduce the empty heart rate, master the correct sowing time, and make them grow in an environment with high temperature day and night.

2. Planting density

Radish planted in suitable conditions on the plot, if the plant spacing is wide, the fleshy roots will grow too fast, resulting in unbalanced growth with leaves, and the nutrients produced by photosynthesis of the leaves cannot meet the growth needs of the roots, resulting in hollow.

Control methods: reasonable close planting, maintain a reasonable distance between plant spacing, should not be too wide, should not be too dense, so that with leaf growth in a balanced situation.

3. Improper management of fertilizer and water

Radish fertilization improper is will cause hollow, especially in the late topdressing, topdressing too late, excessive, topdressing with improper, so that excessive nitrogen fertilizer application, resulting in vigorous growth of the ground parts, root hypertrophy, resulting in hollow. In addition, moisture is also one of the main factors causing hollow, in the fleshy root growth period, if the lack of moisture, the root does not get sufficient moisture to form growth, it will cause hollow, in addition to watering different, early to keep the soil moist, late soil dry, resulting in nutrients can not be normal transport accumulation, easy to hollow.

Control methods: strengthen fertilizer and water management, reasonable watering and fertilization, fertilization should be based on the growth status of plants, fertilization principle is to base fertilizer, supplementary topdressing, reasonable combination of nitrogen, phosphorus and potassium fertilizer, in the late application of appropriate boron fertilizer, can reduce the probability of hollow fertilizer and water. Pay attention to uniform watering, keep the soil moist, timely watering when drought, timely drainage and waterlogging prevention when rainy.

4. Improper harvesting and storage

In planting too late harvest will also cause hollow, especially in spring and summer planting radish, easy to occur due to late harvest and cause hollow phenomenon. When stored, if the temperature of the storage place is too high, and the humidity is low, the radish's respiration is faster, it will like a lot of water and cause hollow, and the temperature is too low and it will cause hollow because of freezing damage.

Prevention and control methods: master the correct harvest time, timely sale after harvest, to avoid hollow conditions due to storage problems.

The above is the reason and prevention method of radish hollow brought by pro-agricultural network. I hope to help you. If you want to know more, please pay attention to pro-agricultural network.
