Autumn radish dressing can generally be divided into 3 to 4 times. The first topdressing can be carried out after the seedlings, such as insufficient base fertilizer, radish seedlings grow weaker, can be the first time after the seedlings to recover the seedlings, per acre topdressing ammonium sulfate 7~10 kg. The second top dressing can be done after the seedlings are finished. At this time, the radish's fleshy roots are rapidly expanding, requiring more water and fertilizer, and 12 to 20 kg of ammonium sulfate can be applied per acre. The top dressing method is: before the irrigation, sprinkle the fertilizer on the shade of the ridge at a distance of 6 to 10 cm from the plant, then water it, or apply water after the soil is applied on the ditch. Can also be applied per acre chaos Shifen 1000 ~ 1200 kg, combined with watering. The third time dressing can be carried out about 15 days after the second dressing, about 1,000 kg of cooked thin manure per acre, and the top dressing while watering. The fourth fertilizer can be applied for about 15 days after the third fertilizer application, and 12 to 20 kg of ammonium sulfate can be applied per acre, and 900 to 1200 kg of decomposed feces can also be used.
In addition, radish is very sensitive to boron, boron fertilizer can promote a big heart radish, soil boron deficiency will lead to radish hollow, so pay attention to foliar spray boron fertilizer. The specific method is: from the radish seedlings grow 2 to 3 true leaves from the beginning to harvest about half a month, spray once every 15 to 20 days boron fertilizer, each mus of 150 grams of borax or boric acid 100 grams, first After dissolving with a small amount of warm water, spray 60 to 75 kilograms of water evenly. Spraying time is appropriate in the evening.
Autumn radish topdressing also pay attention to two points: First, the amount of nitrogen fertilizer to be applied, too much nitrogen fertilizer is easy to make bitter radish; Second, each fertilizer should be poured once after the water, in order to facilitate the growth of radish.
