If you do not pay attention to these points, it may be counterproductive to fertilize the soil in multi-span greenhouses
1. Increase the application of organic fertilizers to provide comprehensive nutrition for vegetable growth and enhance the buffering capacity of soil nutrients.
2. After the vegetables are harvested, the soil should be plowed deeply, and the salt-rich topsoil should be turned into the lower layer, and the relatively less salt-containing lower layer soil should be turned into the upper layer to reduce salt damage.
3. Take advantage of the stubble gap to remove the film, and let the salt in the surface layer of the soil leaching to the deep layer through sun and rain or flood irrigation.
4. Vigorously promote formula fertilization, which can not only coordinate the balance of soil nutrients, but also slow down soil salinization and acidification.
Only with good soil nutrients can vegetables grow better, which is more conducive to the development of the ecological environment in multi-span greenhouses, reducing the occurrence of diseases and pests, and the healthy development of ecological cycle is also the balance pursued by multi-span greenhouses.
