What are the growing environment requirements for daikon radish? Detailed explanation of cultivation conditions

Daikon radish is a root vegetable of the Brassicaceae family, and it is also a vegetable often grown in homes and on farms. It has many therapeutic food benefits. During cultivation, daikon radish has unique requirements for water, temperature, light, nutrients, soil, and more. Only when these conditions are suitable will it grow well, and the goal of increasing yield and quality be achieved.

1. Water

Daikon radish is mainly composed of water; about 70% of the root is water, so during the root expansion stage it needs a continuous and abundant water supply. Generally, once it enters the rooting stage, it can be irrigated once a week to keep the soil moist, which helps the roots take hold and expand, all the way until the root matures and is harvested. During this period, if there is drought, increase the irrigation amount at night; irrigating too rapidly during the day can easily cause root cracking.

2. Temperature

Daikon radish is generally sown in summer and autumn, and begins to expand before winter. In winter it can tolerate low temperatures of 1 to 2 degrees below zero. After maturity, it should be harvested as early as possible; do not leave it over winter, as overwintering will cause cold damage, and it will also bolt and become hollow due to vernalization. In the early stage, the temperature needed for seed germination is between 20 and 25 degrees; keeping the seedling stage temperature at 18 to 25 degrees also allows good growth; the most suitable temperature for leaf growth is between 13 and 18 degrees, and high temperatures are not good for leaf growth. During the expansion stage, the temperature can be within the range of 6 degrees to 20 degrees, so attention should be paid to the sowing period.

3. Light

In the early stage, daikon radish also needs more light hours for vegetative growth, which helps promote leaf growth, then photosynthesis produces nutrients to supply growth and store nutrients for the root system. In the later stage of root expansion, the time receiving light can be reduced; the root needs a dark environment to grow. General natural conditions can meet the light requirements.

4. Soil

Because daikon radish is mainly harvested for its fleshy root, the planting soil should preferably be deeper than the soil used for other vegetables. When plowing the soil, it should be plowed to a depth of 35 cm, which is good for root growth, prevents forking, and makes growth smoother. Because it absorbs a lot of water, the soil should be loose and not prone to water accumulation, so that disease occurrence can be reduced.

5. Nutrients

The selected soil must be fertile, and base fertilizer must not be omitted. The base fertilizer should be mild, low-concentration farmyard compost. Apply sufficient base fertilizer, with accurate fertilization depth, and it should be a fertilizer with long-lasting effects. In the early stage of topdressing, mainly apply nitrogen fertilizer to promote growth, and an appropriate amount of potassium fertilizer to strengthen the stems. In the later stage, mainly apply potassium fertilizer and an appropriate amount of phosphorus fertilizer to promote root expansion, and do not apply nitrogen fertilizer, so as to balance growth.

The above are the specific requirements of daikon radish for its growing environment. The more conditions that can be met, the better the growth quality. If conditions are limited and fewer requirements are met, the quality may be more stable. In any case, it still depends on the actual production situation.
