Radish fertilization technology points

The goal of the cultivation of radish fertilization technology is to promote the coordinated growth of the underground and aboveground parts to obtain fleshy roots. According to the production measurement, for every 1000 kilograms of radish produced, it is necessary to absorb N2.1 to 3.1 kg, P2O5 0.8 to 1.9 kg, and K2O 3.8 to 5.6 kg from the soil. The ratio of the three is 1:0.2:1.8. It can be seen that radish is a potassium-based crop, and should not be applied excessively. In addition, radish is more sensitive to boron, and the use of foliar sprayed boron fertilizer in the early and prosperous period of fleshy root expansion can effectively improve the quality of radish.

First, the base fertilizer: The roots of the radish are developed, and the base fertilizer needs to be applied. Before the sowing, the deep-turning of the organic fertilizer is applied in 2000 to 2500 kg per mu, the grass ash is 100 kg, the mixed phosphate fertilizer is 35 kg, and the compound fertilizer is 35 kg. Organic fertilizer is combined with inorganic fertilizer, and too much fertilizer is prone to bitterness. In the boron-deficient area, 1 kg of boron fertilizer can be applied with the base fertilizer to prevent the radish black heart. Linyi Fertilizer Network Copyright

Second, topdressing: radish fertilization is based on base fertilizer, supplemented by topdressing, short-term growth can appropriately reduce topdressing, while long-term growth is to stage topdressing, but topdressing should be centered on the expansion of fleshy roots. In the topdressing, mastering the right time, the staged component topdressing is the key to obtaining high quality and high yield, and we must grasp the principle of being light, heavy and light. Generally, the first top dressing is carried out in the seedling stage. When the seedlings have two true leaves unfolded, the fertilizer can be combined with the weeding soil, and the human excrement or the use of 10-15 kg of urea is applied to the water after pouring into the water; During the period of a€?outcropa€?, 2 heavy fertilizers should be applied, and 30 kg of compound fertilizer should be applied per mu. The radish basically meets the needs of future growth after chasing twice the fertilizer. Linyi Fertilizer Network Copyright
