Fertilizer use should be done simultaneously with growing vegetables and fertility. The use of animal fat and vegetable fertilizers is preferred to be 1 to 1. Each vegetable is generally applied at the end of 45-60 grams of organic fertilizer per hectare, followed by organic fertilizer 1500 kg per hectare.
To apply the base fertilizer, 80 percent of the total amount of fertilizer is used as a base fertilizer, and the soil is uniformly mixed with the fertilizer in the tillage layer to facilitate root absorption. At the same time, it is necessary to apply top dressing. For plants with high planting density and shallow roots, topdressing can be applied in a top-dressing manner. When the vegetables grow to 3 to 4 leaves, the fertilizers are air-dried, uniformly spread into the vegetable field, and watered in time; Large and rooted vegetables can be topdressed with a trench, pay attention not to damage the root system when the ditch is opened, and to spread the fertilizer into the ditch and water it in time after the soil is covered. For vegetables with a large plant spacing, open the vegetables. Point dressing mode.
