土壤调理剂(田美乐)对菜心生长、品质及土壤理化性状的影响

Effects of Soil Conditioner (TM Agricultural) on the Growth and Quality of Flowering Chinese Cabbage and the Soil Physicochemical Properties

为探讨并应对土壤连作障碍对叶菜的不良影响,本试验以菜心为材料,以喷清水为对照(CK),土壤调理剂(田美乐)分别稀释500倍(T1)、1000倍(T2)、1500倍(T3)等量喷施土壤,研究不同稀释倍数对菜心产量、品质、土壤理化性状和植株养分吸收的影响。结果表明,喷施500倍和1000倍的土壤调理剂处理促进了菜心的生长,喷施1000倍和1500倍的处理提高了菜心的营养品质;喷施土壤调理剂提高了土壤pH值、降低了EC值,并改善了土壤的物理性状。综合来看,喷施1000倍土壤调理剂的T2处理最适合菜心,并且此处理提高了植株的矿质养分含量。

The experiment was carried out to investigate and deal with the harmful influence of soil continuous cropping obstacle on leaf vegetables. Flowering Chinese cabbage was used as plant material, and spraying water was as control (CK), also soil conditioner (TM Agricultural) was diluted 500 times (T1), 1000 times (T2), and 1500 times (T3) in the experiment. Different treatments were sprayed the same volume to the soil. Effects of different concentrations of soil conditioner on plant growth, nutritional quality, soil physical and chemical properties and nutrient absorption were studied. The results showed that, spraying soil conditioner 500 times and 1000 times promoted the growth of flowering Chinese cabbage, and spraying soil conditioner 1000 times and 1500 times improved the nutritional quality of product organ. Spraying soil conditioner increased soil pH value, decreased soil EC value and improved soil physical properties. In conclusion, spraying 1000 times soil conditioner (T2) was the most suitable treatment for flowering Chinese cabbage, and this treatment increased plant mineral nutrient content.
