Field Management Skills for High Yield Radish in Autumn

At this time, the temperature in many areas began to drop. For radishes, this is a good time for the roots to expand. Then, what important tasks for radish field management should be grasped by the growers at this time?

Field Management Skills for High Yield Radish in Autumn

1. Sowing period

According to the climate characteristics after the beginning of autumn, you can choose to sow from early August to mid-August, and you can harvest around November. If you plant on a plot with poor soil fertility, if the previous crop is a food crop, you can sow in advance to extend The growth period has a significant effect on the increase of output. Vegetable plots with fertile soil and more serious pests and diseases can be planted at a suitable late stage to avoid the peak period of pests and ensure yield and quality.

2. Fine land preparation

For radish cultivation in autumn and winter, you should choose plots that are convenient for irrigation and drainage. Sandy loam and loam soil are suitable. The land must be cultivated in time before planting. The cultivated land should be early, the quality of the cultivated land should be good, and the depth of the cultivated land should be consistent and not leaked. For plowing, the upper and lower layers of soil should be completely broken to ensure that the soil is loose. In production, wide ridges should be used for single-row cultivation. When preparing the ground, the ridge width is 66 cm, the ridge height is between 10 and 12 cm, and each ridge can be planted in one row.

3. Apply base fertilizer

The growth rate of radish itself is relatively fast, so the demand for fertilizer is large, so base fertilizer can be applied before sowing. It is recommended to apply 2500-3000 kg of decomposed ring fertilizer, 100 kg of plant ash, and 25-30 kg of superphosphate per mu. , It can be applied in conjunction with the cultivated land, and it can be mixed evenly with the soil. The applied base fertilizer is decomposed under high temperature, otherwise it is easy to damage the roots, which is extremely detrimental to the growth of radishes, which increases the number of underground pests, and the radishes are also easy to form branches and deformed roots.

4. Seeding techniques

Autumn radishes are generally broadcasted, followed by drilled seeding, and hole seeding. Large varieties are mostly used for drilling, medium types are mostly used for drilling, and small varieties can be used for drilling or broadcast. The main seeding must be sparse and suitable. After sowing, cover with about 2 cm thick soil. You can water first, then cover the soil, or you can first sow and then water. Generally, large radish varieties have a row spacing of 40-50 cm and a plant spacing of 40 cm; medium-sized radish varieties have a row spacing of 17 to 27 cm; small four-season radishes have a row spacing of 5-7 cm and a plant spacing of 5-7 cm.

5. Digging

Usually one month before maturity, use the tip of a small knife to cut directly to the new tooth, which is the middle position of the lower part of the radish tassel, and then use the tip of the knife to dig out this piece. The core of radish is indeed conducive to high yield. Because in the late stage of radish expansion, if some are not dug out, some new radishes will grow out. If this happens, we need to dig the heart a second time, so we must pay attention when digging the heart, especially for large-scale planting. If this happens, it will lead to an increase in labor costs. This is also digging. A drawback brought by the mind.

6. Skimming leaves

The method of leaf skimming is 25 days before harvest. The fleshy root enlargement has almost been finalized, and its root matter accumulation process and transformation are a process of accumulation, so leaf skimming at this time is the best. We have to selectively remove some useless radish tassels. Generally, the easiest way is to remove the outer radish tassels, leaving only two or three slices. This is generally enough. In this way, its ventilation and light transmission conditions will be improved, and nutrient supply will give priority to fleshy roots, and begin to accumulate dry matter, so that in the later stage. The occurrence of chaff and soft rot will decrease.
