Abstract: It was conducted to research the effect of Phyto-CatTM soil conditioner on the physiological and chemical properties of the soil and the physiological characteristics of non-bearing cabbage, and to explore its effectiveness as an alternative to traditional chemical fertilizers.We take non-heading Chinese cabbage plants as the test object, and adopt a multi-factor single-level method to study the effects of four treatments:study basal fertilizer(CK), basal fertilizer+Phyto-CatTM soil conditioner(T1), basal fertilizer+conventional fertilization(T2), basal fertilizer+conventional fertilization+The effects of four treatments with Phyto-CatTM soil conditioner(T3)on the physiological characteristics of non-heading Chinese cabbage, soil physical and chemical properties and fertility levels.The results indicated that compared with CK treatment, T1, T2 and T3 treatments could significantly increased the yield, chlorophyll content, leaf soluble sugar and root activity(tetrazole reduction intensity)of non-heading cabbage.Three processing each index had respectively increased by 11.5%-27.9%, 9.8%-22.7%, 7.8%-16.3%, 12.4%-24.8%;compared with CK treatment;T1 treatment made the test soil pH, water-stable aggregate content, field water holding capacity, soil organic matter, available nitrogen, available phosphorus, and available potassium content increase by 5.9%, 5.3%, 2.1%, 18.42%, 7.32%, 29.89% and 33.97%;Respectively, soil bulk density decreased by 9.5%.The research results indicated that the application of Phyto-CatTM soil conditioner had a significant effect on the physiological characteristics and soil properties of non-heading Chinese cabbage. Under the condition of applying no chemical fertilizer, Phyto-catTM soil conditioner played an obvious role in improving soil properties and increasing crop yield. It could replace chemical fertilizer application on the premise of ensuring crop yield, and open up a new way for pollution-free agricultural production.
