What to Do About Radish Seedling Death? Detailed Explanation of the Latest Control Methods
Radishes are grown over an extremely wide area in our country, but during the radish growing process, the phenomenon of radish seedling death often occurs, which gives farmers an extreme headache. So what should be done about radish seedling death? Below, the editor will share with everyone the control methods for radish seedling death, let's take a look together.
1. Crop rotation and stubble alternation
Radishes are not suitable for continuous cropping, so rational crop rotation is needed, putting the farming system of crop rotation and stubble alternation into practice, while also reducing the frequency and amount of insecticide use, increasing soil permeability, improving soil vitality, and reducing herbicide residues. After planting radishes, management should be strengthened: apply whatever nutrients are needed, apply them in decomposed form in the amount needed, increase the residual amount of fertilizer in the soil, restore soil vitality, and improve the soil environment.
2. Temperature control
The suitable temperature for radish germination is around 20 degrees; the seedling stage can tolerate low temperatures of about 5 degrees, and can also endure prolonged sub-zero low temperatures for a long time. However, short periods of high temperature and low temperature are extremely favorable for radish seed germination. The suitable temperature for leaf growth is 20 degrees, and the suitable temperature for fleshy root growth is around 16 degrees. Once the temperature is lower than 20 degrees, radish growth is weak and the yield is relatively low. Therefore, in the later stage of radish growth, plastic film mulching cultivation can be used, so that the radish seeds can flower and seedling death problems absolutely do not occur. Seeds need to be disinfected, and attention should be paid to temperature adjustment during the seed growth period.
3. Fertilizer use
Fertilizer is very effective for preventing radish seedling death. A special-effect foliar fertilizer dedicated to preventing radish seedling death and yield reduction can be used to prevent radish seedling death and root rot. When using herbicides after radish harvest, at the three-leaf-one-heart stage after emergence, and when the lower part of the root system begins to expand, these three stages should be sprayed on the ground and on the leaves in three separate applications, which can produce unexpected effects. Fertilizer should be used rationally: apply the appropriate fertilizer for whatever nutrients are needed, and the amount of fertilizer applied should be based on soil fertility and radish growth conditions. At the same time, when spraying the special-effect foliar fertilizer, combining it with Xinguozhimo can not only increase soil permeability and improve soil vitality, but also reduce pesticide residues.
