The latest course of management techniques and methods in radish expansion period

Radish is a typical root vegetable, which is basically planted in all parts of our country. When planting radish, the management work is very important, when we manage, we need to adjust the management technology reasonably according to the growth stage of radish. Especially during the turnip expansion period. So how to manage it during the turnip expansion period? The following editor brings you the management technology of the turnip expansion period, let's have a look!

1. Rational fertilization

During the turnip expansion period, fertilization is very important. Because during this period, radish needs a lot of nutrition to ensure that it can expand normally. Therefore, first of all, we need to do a good job in fertilization, fertilizer should be based on phosphorus and potassium fertilizer, to apply the right amount of phosphorus and potassium fertilizer in time. The method of fertilization can be foliar spraying. After diluting potassium dihydrogen phosphate with water, it can be sprayed to the leaves. Supplying sufficient phosphorus and potassium to radish can accelerate the growth rate of fleshy root. And potassium dihydrogen phosphate can also prevent radish fruit cracking and bifurcation.

2. Timely watering

Like fertilizer, watering during the expansion period of radish is also very important. During this period, radish also needs a lot of water, so we should pay attention to keep the soil moist and have enough water. However, when watering, we should pay attention to control the watering time and the amount of watering, not at noon, but in the morning and evening. It is best to be able to do it in the morning, because if it is watered at noon, it is very easy to crack fruit because of the excessive temperature difference at the root. Then in the watering should be based on the principle of small water frequently, do not flood irrigation, to avoid excessive water flooding.

3. Ploughing and weeding

In addition to doing a good job of fertilizing and watering, we should also pay attention to the work of ploughing and weeding during the turnip expansion period. Proper mid-tillage can avoid soil consolidation, improve soil permeability, enhance the absorption and respiration capacity of roots, and promote the normal expansion of roots. At the same time, it can also inhibit the growth of weeds, the main purpose of weeding is to avoid weeds and rob the expanded nutrition and water of radish. Therefore, we must pay more attention to concentrate nutrition on radish plants to ensure radish yield and quality.

4. Pest control

Finally, we should also do a good job in the prevention and control of diseases and insect pests. The common diseases and insect pests in the expansion period of radish are aphids, root rot and so on. These diseases will affect the growth of various organs of radish in varying degrees, especially the root growth of radish. Therefore, we should pay attention to regular disinfection to eliminate diseases, insects and germs in the field. At the same time, we should often observe the growth of radish, when it is found that there is an abnormal situation, we should deal with it in time, and make corresponding treatment after checking out the specific reasons to ensure the normal growth of radish.

The above is a brief introduction to the management technology of radish expansion period. That's all for today's introduction. This article is for reference only. I hope it can help you all.
