温室土壤管理主要是改良土壤,培肥地力,以改善其理化性状,创造果蔬根系生长发育的良好环境,防止土壤酸化、盐化及营养元素的失衡。增施有机肥:有机肥含有果蔬需要的各种营养元素且释放缓慢,不会使土壤溶液浓度过高或发生元素过剩。有机肥中还含有大量的微生物,微生物能促使被土壤固定的营养元素释放出来,增加有效成分的浓度。但含氮有机肥的使用量要适中。
Greenhouse soil management is mainly to improve the soil, fertility and fertility, to improve its physical and chemical properties, to create a good environment for the growth and development of fruits and vegetables roots, to prevent soil acidification, salinization and nutrient imbalance. Application of organic fertilizer: Organic fertilizer contains various nutrients required for fruits and vegetables and slow release, will not make the soil solution too high concentration or elemental excess. Organic fertilizer also contains a large number of microorganisms, microorganisms can promote the release of nutrients fixed by the soil to increase the concentration of active ingredients. However, the amount of nitrogenous organic fertilizer to moderate.
