How to fertilize radish?

Radish is one of the ancient cultivated crops in the world, which is widely planted all over the world. How do you fertilize that kind of radish?

First, how to fertilize the radish?

1. Fertilization of white radish

(1) Base fertilizer: the type and amount of base fertilizer often vary with soil and variety. General base fertilizer can be sprinkled with rotten barnyard manure 2500-3000kg, plant ash 50kg, calcium superphosphate 25-30kg, ploughed into the soil, and then applied human fecal urine 2500-3000kg, dried and ploughed into the soil, raked flat to do the border. When applying soil miscellaneous fertilizer in many areas of the north, adding a certain amount of cake fertilizer can enrich the fleshy root tissue, and it is not easy to be hollow during storage.

(2) topdressing: the first topdressing of white radish applied thin human manure between rows when two true leaves were grown in the seedlings. When the second topdressing was applied in the second seedling, potassium sulfate 5kg was applied. When entering the peak period of leaf growth, quick-acting nitrogen fertilizer should be applied once, and when entering the peak stage of fleshy root expansion, compound fertilizer should be applied once. 20 days before harvest, sprinkle once a week and spray 0.2% potassium dihydrogen phosphate twice in a row for foliar topdressing.

two。 Carrot fertilization

(1) Base fertilizer: carrot base fertilizer can be applied in two ways: spreading and furrow fertilization. all solid fertilizers should be mixed with fine soil. Fertilization has a great influence on the shape of fleshy roots. when the amount of chemical fertilizer is more and organic fertilizer is less, the proportion of abnormal roots increases significantly, and the application of rotten organic fertilizer as base fertilizer can reduce the formation of abnormal fleshy roots.

(2) topdressing: to plant carrots, in addition to applying base fertilizer, topdressing should be applied for 2-3 times. The first time was 20-25 days after emergence, after 3-4 true leaves were grown, ammonium sulfate 5-6kg and potash fertilizer 3-4kg were applied every 667m2. The second topdressing was carried out after the carrot seedlings were fixed. Ammonium sulfate 7-8kg and potash fertilizer 4-5kg were used every 667m2. In the peak stage of root expansion, the amount of fertilizer used in the third topdressing was the same as that in the second topdressing. The type of fertilization, in addition to chemical fertilizer, can also use mature human feces and urine, 1000-2000kg per 667m2. The method of topdressing can be poured with water, or human feces and urine can be splashed with water.

Fertilization of radish is mainly based on soil fertility, radish variety, producing area environment and other factors. The above values can only be used as a reference, not blindly applied.
