摘要
Rare earth phosphate fertilizer (REPF) as base fertilizer (750 kg per hm2) was applied in the western area of China during the "Tenth Five-Year Plan", and the results show as follows: compared with calcium superphosphate (CK), REPF increases crops yields for maize by 17.0%, for rice by 10.5%, for wheat by 24.2%, for potato by 18.5%, for cabbage by 16.3%, for Chinese cabbage by 16.4%, for beet by 6.5%; decreases the diseased plant rate for common smut of maize by 1.0%, for maize stalk rot by 1.2%, for wheat take-all disease by 7.8%, for wheat root rot by 3.2%, for potato blackleg disease by 1.4%, for potato late blight by 6.6%; increases the sugar content of beet by 0.9°S.
