The latest course of planting techniques and methods of autumn radish

Radish is a very common vegetable in winter, which has great health care effect and is welcomed by many people. And the medicinal history of radish is also very long, radish has various effects such as eliminating accumulated food, invigorating stomach and relieving diarrhea. With the passage of time, it is also gradually to the planting season of autumn radish. So the editor will give you a brief introduction to the planting technology of autumn radish today. Let's take a look at it.

1. Sowing environment

First of all, we have to choose a suitable variety, such as exposed green and so on. Because the cold tolerance of radish is relatively poor, so like to grow in a cool environment. The lowest temperature for seed germination is 3 degrees, and the most suitable temperature for germination is about 22 degrees. When planting, we must pay attention to control the sowing time, sowing too early and too late will affect the growth of autumn radish. If sowing too early, it is easy to cause soft rot and other diseases, but if sowing too late, the growth ability of radish is poor, its size is small, and its yield will decline. It should usually be sown about 4 days after the Beginning of Autumn.

2. Select land and sow seeds

First of all, we need to choose a good soil, autumn radish planting soil to ensure that there are no diseases and insect pests, and sufficient fertility. The previous crop of the soil should not be a cruciferous crop. Then do a good job of soil preparation and turn the soil about 30 centimeters deep. Then apply sufficient farm manure, about 3000kg per mu. Plough the soil thoroughly and rake it fine. Then the soil is made into high ridges before sowing, and the transplanting survival rate of radish is relatively low. Therefore, the sowing method is mainly direct seeding, the planting density is controlled, the sowing depth is kept at about 1.5cm, and each sowing hole is about 4 seeds.

3. Seedling stage management

When the seedlings grow about two true leaves, it is necessary to do a good job of interseedling work, which is mainly to remove some weak seedlings that are harmful to diseases and insect pests. Provide sufficient growth space for robust seedlings, each hole to retain about 3 plants, generally in the whole seedling stage to seedling about three times. Then, when about 4 true leaves grow out of the seedlings, the seedlings can be fixed, and timely seedling determination is of great help to the growth of autumn radish. Finally, we need to weed properly to prevent weeds from grabbing the growth and nutrition of autumn radish seedlings.

4. Field management

The fertilizer and water management of autumn radish is not only the key to balance plant growth, but also the main measure to increase the yield of autumn radish. In the early stage of planting, more topdressing should be appropriate to provide nutrition for the expansion of fleshy roots. In addition to applying sufficient base fertilizer, we should also apply fertilizer appropriately according to the growth of autumn radish, increase the proportion of phosphorus and potassium fertilizer, and promote nutrition transformation. Control the dosage, especially nitrogen fertilizer, to ensure the normal growth of autumn radish. Finally, we should reasonably control the moisture according to the growth stage of autumn radish, for example, when sowing, we should water more to promote germination. But at any time, do not have too much water, otherwise it is easy to cause succulent root rot and cause diseases and insect pests.

The above is a brief introduction to the planting technology of autumn radish. The planting technology of autumn radish is very simple, and the yield is relatively high, but we should pay attention to the management when planting. That's all for today's introduction.
