How many jin per mu does white radish yield? The best time to plant and harvest is in which month
White radish, a root vegetable, a plant of the genus Raphanus in the cruciferous family. It has been cultivated for a thousand years to date. So when planting it, how many jin can one mu of land usually produce? When is the best time to plant? In which month is it harvested? From Master Wang in Daoxian County, Hunan, we learned that there are many decisive factors for white radish yield per mu; the yield is related to variety and cultivation management. In a normal year it is about 2500 kg to 5000 kg, and with good management the yield can reach more than 5500 kg or even higher.
When is the best time to plant white radish? In which month is it harvested?
According to the radish cultivation season, it is divided into autumn radish, generally sown in mid-to-late July. Harvested in mid-September; if the climate is suitable, the yield is high and the quality is good; summer-autumn radish, sown in May-June, harvested in July-August; if sown too early, it is prone to premature bolting, and it is mainly used as a supplement during the autumn slack season.
As an off-season radish cultivation, depending on the variety, sowing generally starts in April-May in mid-altitude areas of 800—1200m, with harvest in June-July; in high-altitude areas, sowing is in May-July with harvest in July-September. Alpine radish cultivation uses varieties with strong winter hardiness and is planted for two crops, and can be marketed from June until the end of October.
Field management of white radish
Thinning. After the seedlings emerge, they grow rapidly, so thinning must be done in time; otherwise crowding and shading will occur, causing spindly growth. Thinning should be done early, generally 2 times; the 1st time is at 2 to 3 true leaves. The principle of thinning is to remove the inferior and keep the superior. At the time of root splitting, select plants with the characteristics of the original variety for final thinning, keeping 1 plant per hole at final thinning.
Watering. Germination stage: water fully, with soil moisture content above 80%, to ensure fast and uniform emergence. Seedling stage: the roots are shallow and water needs are small, but supply must still be ensured; soil moisture content is about 60%, and the principle of watering little but often should be followed. Before root splitting, seedlings should be hardened to encourage the taproot to grow downward. Leaf growth peak stage: this stage needs more water, so irrigate appropriately, but water should be properly controlled in the later stage to prevent excessive leaf growth from affecting fleshy root growth. Root growth peak stage: water fully and evenly to prevent root cracking; soil moisture should be maintained at 70-80%, and air humidity at 80-90% is suitable. Watering is still needed until the late growth stage to prevent hollowing.
Cultivation, weeding, and earthing up. Because white radish growth requires high air content in the soil, the soil must be kept loose, and cultivation should be carried out in a timely manner, combined with weeding, and earthing up must be done during cultivation. In production, the three tasks of cultivation, weeding, and earthing up are generally combined.
Pest and disease control. Field management should pay attention to integrated control of white radish diseases. The main diseases include mosaic disease, viral disease, soft rot, and black heart disease, etc. The main pests harming white radish are aphids, cabbage caterpillars, etc. The key to disease control lies in strengthening cultivation management, making the plants robust, enhancing disease resistance, and carrying out integrated control in combination with chemical control.
