The causes and control methods of the latest hollow radish

Radish is a common vegetable, but what bothers vegetable farmers in the process is that hollow radish has very low nutritional value, and it will lead to low yield, and most importantly, it can not be sold, resulting in a loss. So what is the reason for the hollowness of radish? How to prevent and cure it? Let's take a look at the detailed introduction of the pro-agricultural network.

1. Variety and sowing date

The hollow radish may be caused by the variety, some fleshy dense small radish, the growth is slow, when the growth balance with the leaves, not easy hollow; while the fleshy sparse large radish, the root growth far exceeds the leaf growth, easy 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 hollow.

Prevention and control methods: as can be seen from the above, selecting small radish with dense flesh can reduce the hollow heart rate, grasp the correct sowing time, and make it grow in an environment with high temperature day and night.

2. Planting density

If the radish is planted on the land with suitable conditions, if the row spacing is wide, the fleshy root will grow too fast, resulting in a loss of balance with the leaf growth, and the nutrients produced by leaf photosynthesis can not meet the needs of root growth, so it will be hollow.

Prevention and control methods: reasonable close planting, keep a reasonable distance between rows, should not be too wide, should not be too dense, so that the growth of leaves is in a balanced condition.

3. Improper management of fertilizer and water.

Improper fertilization of radish will cause hollow, especially in the later stage of topdressing, topdressing is too late, excessive topdressing, improper topdressing, resulting in excessive application of nitrogen fertilizer, resulting in vigorous growth of aboveground parts, root hypertrophy, resulting in hollow. In addition, water is also one of the main factors causing hollow, in the fleshy root growth period, if the lack of water, the root can not get enough water to form growth, it will cause hollow, in addition, watering is different, the soil is moist in the early stage, and the soil is dry in the later stage, resulting in abnormal transport and accumulation of nutrients, which is easy to hollow.

Prevention and control methods: strengthen fertilizer and water management, reasonable watering and fertilization, fertilization should be based on the growth status of the plant, but the principle of fertilization is based on base fertilizer, supplemented by topdressing, reasonable combination of nitrogen, phosphorus and potassium fertilizer, and applying appropriate amount of boron fertilizer in the later stage. it 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 it is overcast and rainy.

4. Improper harvesting and storage

Too late harvest in planting will also cause hollowness, especially radish planted in spring and summer, it is easy to cause hollowness due to late harvest. If the temperature in the storage place is too high and the humidity is low, the radish will breathe faster and will like a large amount of water and cause hollow, while too low temperature will cause hollow because of frost damage.

Prevention and control methods: grasp the correct harvest time and sell it in time after harvest to avoid hollow conditions due to storage problems.

The above are the causes and prevention methods of radish hollowness brought by pro-agricultural network. I hope to help you. If you want to know more, please pay attention to pro-agricultural network.
