摘要
7年的不同肥料配比试验表明，肥料生产力占桃树总产量的38．59％，其中钾肥对桃树增产的作用最大，占增产比重的20．74％，磷肥的边际产量最高，氮肥的作用较小，只占增产比重的5．37％，因此生产上应增施磷、钾肥，控制氮肥。
The results from 7 years fertilizer composite experiment showed that: the productivity of fertilizer took 38. 59 Percentage of the production of peach(Prunus prsica L. Batsch. ) trees; Anong which, the potash fertilizer(K), which took 20. 74 percentage, had the greatest effect on increasing production, meanwhile the ni-trogen fertilizer(N), which took 5. 37 percentage, took the lowest benefit; the phosphate fertilizer (P) had the highest accelerating production. Therefore, it was recommended to add P, K, control N ferticising.
