| Abstract: | The yield response of Chinese cabbage to phosphate fertilizer and manure was studied. The effect of over-application of phosphate
fertilizer and manure on plant total phosphorus content and phosphorus accumulation in soil was also investigated. The experiment
was arranged in a plastic barrel in the field for two years. Application of phosphate fertilizer at the rates of 150–600 mg·kg−1 gave a yield increase of 14.9%–21.5% of Chinese cabbage. Application of manure at the rates of 33.3–-133.2 g·kg−1 gave a yield increase of 18.2%–25.9%of the crop. There was no significant difference of yield response at the rates of 150,
300 and 600 mg·kg−1 phosphate fertilizer, and no significant yield response to the application of phosphate fertilizer after applying manure.
The total P content in Chinese cabbage was increased gradually with the rate increase of phosphate fertilizer and manure.
Phosphorus was absorbed luxuriously by the plant with over-application phosphate fertilizer and manure. The content of total-P,
Olsen-P, water-soluble P, biological available P in the soil was increased with the rate of phosphate fertilizer and manure.
Organic phosphorus in the soil was increased by the application of manure. Olsen-P had high correlations with water-soluble-P
and biological available-P, but there was a poor relationship between Olsen-P and organic-P.
