Requirements for growing environment of white radish

White radish is a root vegetable of Cruciferae, and it is also a vegetable often planted in families and farms. It has many therapeutic effects. In cultivation, white radish has unique needs for water, temperature, light, nutrition, soil, and so on. Only when the conditions are suitable, the growth will be good, and the goal of improving yield and quality will be achieved.

1. Moisture

White radish is mainly composed of water, and about 70% of the rhizome is water, so a large amount of water supply is needed during the period of rhizome expansion. Generally speaking, when it enters the rooting period, it can be irrigated every other week to ensure that the soil is moist, which is conducive to rooting and expansion until the rhizome is harvested. During the period of drought, if the amount of irrigation is increased at night, if the irrigation is too rapid during the day, it is easy to crack the roots.

Second, temperature

White radish planting, generally sowing in summer and autumn, began to expand before winter, can withstand a low temperature of minus one or two degrees in winter, can be harvested as soon as possible after maturity, do not stay through the winter, will suffer frost damage, will also bolting by vernalization, hollow. The temperature needed for early seed germination is between 20 and 25 degrees, and the seedling temperature is maintained at 18 to 25 degrees. The most suitable temperature for long leaves is between 13 and 18 degrees. High temperature is not conducive to growing leaves. The temperature during the expansion period can be in the range of 6 to 20 degrees, so pay attention to the sowing period.

Third, lighting

The vegetative growth of white radish also needs more light hours in the early stage, which is beneficial to promote the growth of leaves, and then carry out photosynthesis to produce nutrients for growth, store nutrients and supply roots. Root expansion in the later stage can reduce the time of receiving light, and the root needs to grow in the dark environment. General natural conditions can meet the requirements of lighting.

IV. Soil

Because white radish mainly collects fleshy roots, it is best to plant soil deeper than that of other vegetables. when ploughing the soil, it is necessary to plough to the degree of 35 cm, which is conducive to root growth, will not bifurcate, and grows more smoothly, because it absorbs much water. If the soil is loose, it is not easy to accumulate water in order to reduce the occurrence of diseases.

V. Nutrition

The choice of soil must be fertile, base fertilizer must not be applied, base fertilizer must be used with low mild concentration of farm compost, adequate base fertilizer, accurate fertilization depth, if the fertilizer effect is long-lasting. In the early stage of topdressing, the main application of nitrogen fertilizer to promote growth, an appropriate amount of potassium fertilizer to strengthen the stem, in the later stage mainly topdressing potassium fertilizer, appropriate amount of phosphorus fertilizer to promote root expansion, no nitrogen fertilizer, balanced growth.

The above are the specific needs of white radish on the growth environment, the more conditions can be met, the better, the better the growth quality. If there are less conditions to meet the conditions, the quality may be more stable. Anyway, it depends on the actual production.
