Whether it is a greenhouse or a shed, due to the long-term warm and humid environment in the shed, coupled with years of heavy planting, the soil of most sheds will grow green moss of varying sizes. Many farmers have become accustomed to this and have not caused enough Pay attention to it. In fact, the soil in the greenhouse grows green moss, indicating that the salt in the soil has exceeded the standard, so don't underestimate the vegetable farmers.
Green moss is mainly caused by high salt content in greenhouses (such as nitrogen and phosphorus exceeding the standard) and moisture. It does not harm vegetable plants by itself, but the vigorous green moss will “block†soil pores, resulting in greatly reduced soil permeability. So how do you avoid the long green moss in the soil? It is recommended that vegetable farmers strengthen the following management:
Diligent
The main purpose of the plan is to remove the green moss from the surface of the soil and break the surface layer to improve the physical and chemical properties of the soil and improve the permeability of the soil. Note that the strokes should not be too deep, and should be carried out step by step, gradually deepening, so that the roots have a stage of adaptation and buffering, which is conducive to the robust growth of vegetables.
Balanced fertilization
Through soil testing and fertilization, the lack of hydrazine can greatly reduce the amount of chemical fertilizers, avoid soil salinization, and increase the amount of functional fertilizers such as organic fertilizers or microbial agents, gradually improve the soil and alleviate soil salts. Water staining.
Deep soil
Use a deep-deep machine to deepen the soil. It is best to use a deep-turning machine that can be turned to a depth of about 45 cm to break the bottom of the plow and increase the depth of the tillage layer.
Using drip irrigation equipment
Conditional vegetable farmers can install drip irrigation equipment, use membrane drip irrigation to improve fertilizer utilization, reduce soil moisture, and reduce the occurrence of green moss.
