Abstract:

In order to alter the producer’s blindness to the base fertilization of winter wheat, resolve the low yield of wheat caused by irrational fertilization, field experiment was carried out for comparing the effects of several common types of compond (mixed) fertilizer on winter wheat applied before seeding. The results were followed: 2 types of compond (mixed) fertilizer contented N, P and K increased the wheat yield and benefit significantly compared with the other types. Among which the compond (mixed) formula fertilizer with N-P2O5-K2O of 18-18-6 increased the wheat yield and benefit significantly compared with the N-P2O5-K2O of 15-20-5, but the two applying rates of 525 kg/hm2 and 675 kg/hm2 had no marked difference on yield and benefit. So the Compond (mixed) fertilizer with N-P2O5-K2O of 18-18-6 was well suit to Yongnian soil and wheat. The proper base applying rate was 525-675 kg/hm2.
