How to fertilize greenhouse soil

Plastic greenhouse is a highly intensive cultivation place, and soil management is very important. It is very important to pay special attention to soil fertility, reduce soil-borne diseases, avoid continuous cropping obstacles, appropriately increase organic fertilizer, rationally formulate fertilization, and determine reasonable fertilization amount at different growth stages according to the growth law of ginger, so as to improve fertilizer utilization rate.

When cultivating ginger in greenhouse, chemical fertilizer should be applied as little as possible to avoid the harm of high salt concentration. Once the soil is damaged by salt accumulation, in addition to flooding the greenhouse in leisure time to make it naturally seep down to leach out some salt in the soil, we can also consider applying crop straws with high carbon content to desalt, digging deep and changing soil to desalt. If it is serious, you can consider replacing the soil in the greenhouse, or moving the greenhouse to other places to eliminate salt damage.
