Some problems needing attention in radish planting

Radish has a long history of planting in China, so the planting technology has basically been completely mature. However, due to the emergence of more novice growers in recent years, there are some common problems in the process of radish planting. Well, the editor has made an arrangement for you in view of these problems, and at the same time, I hope you can pay more attention to it in the later planting process. Let's take a look at the points for attention in radish planting.

1. Soil

The best planting land of radish is sandy loam with complete soil structure, fertile soil, soft soil, good permeability, good drainage, strong moisturizing and fertilizer preservation. The second is that the pH of the soil is preferably around 5.3 to 7. There is no continuous cropping, and the previous crop is cruciferous plant land is best not to be used to grow radish, easy to get sick.

2. Temperature

We all know that radish is not usually planted in summer, and it will also be harvested before Frosts Descent, which shows that it has certain requirements on the temperature of its growth. Radish seeds have a high germination rate and can germinate at two or three degrees, but the temperature suitable for radish growth is 20 to 25 degrees. When radish is in the seedling stage, it can grow at a high temperature of more than 25 degrees, as well as minus two or three degrees. But when the radish to the growth period, the normal growth temperature had better be 15 to 20 degrees, the temperature can not be lower than 6 degrees, otherwise the radish will suffer frost damage.

3. Watering

The water demand of radish is also different in different growth periods, so we should water it according to its water demand. During the seedling period of radish, generally do not need how to water, except in dry and high temperature weather, in order to avoid the emergence of dead seedlings, need to be watered properly. The maximum water demand of radish is its stem and leaf growth period and underground root growth period, so we can water scientifically according to the weather conditions and the wetness of the soil in the field. Especially in the process of underground rhizome growth, there can be no sudden dry and wet situation, otherwise it is very easy to cause radish cracking; it can not be too dry or too wet, otherwise it will lead to radish underdevelopment or rot and other phenomena, affecting the quality of radish.

4. Fertilization

The growth of radish needs a large amount of fertilizer, but it can not be abused casually, and it needs to be fertilized scientifically according to its growth characteristics. First of all, we should apply sufficient base fertilizer before planting, which is mainly based on organic fertilizer, and combined with appropriate amount of ternary compound fertilizer for soil preparation. Generally, in the case of sufficient base fertilizer, the basic upper part needs to be topdressing growth fertilizer, but if the radish appears yellow or thin in the growing period, then it needs to be topdressing fertilizer, mainly urea. When the radish rhizome is strong, it is best to apply phosphate and potassium fertilizer once, which can promote the growth of the rhizome and ensure the quality of the radish.

Of course, when radish is planted, we also need to pay attention to weeding and pest control. When ploughing, we should pay attention to shallow ploughing, do not hurt the roots of radish, affect the normal growth of radish. And pest control should choose the appropriate pesticide, and reasonable allocation of pesticide concentration, spray control at the right time.
