Abstract

Abstract:

To improve acidic soil and promote crop growth in Pucheng County, this experiment took Pucheng long straw Chinese cabbage as the material to study the soil improvement after applying three different soil conditioners, and the effect on the yield and quality of cabbage. The results showed that in acidic soil with pH 4.8, the soil pH could be increased by 0.8 to 1.1 units and the total amount of exchangeable base could be increased by 65.6%-75.7% under the dosage of 3000 kg/hm². The availability of heavy metals in soil reduced significantly, effective chromium, effective mercury and effective lead decreased by 2.7% to 13.6%, 9.1% to 50.0% and 7.1% to 17.2%, respectively. The application of soil conditioner could improve the yield and quality of Pucheng long straw Chinese cabbage, and the application of slow release silicon had the greatest effect on the yield.

Key words: soil conditioner, Chinese cabbage, pH, yield, quality, acidic soil, Pucheng County
