在提高草地的肥料效率的问题上,有科学根据的定额和不同类型肥料的比例具有特别重要的意义。而这又决定于土壤、气候条件和草层利用状况。在奥卡河河漫滩天然草地的不同地段进行了研究。试验表明、在禾本科-杂类草草层中按 N_(60)P_(60)的定额施入磷肥和氮肥时,其牧草产量较对照高(表1)
Scientifically based quotas and the proportion of different types of fertilizers are of particular importance in raising the efficiency of fertilizers in grasslands. This in turn depends on the soil, climatic conditions and grassland utilization. Research was conducted in various locations on the natural grassland of the Oka River floodplain. The results showed that the yield of forage grass was higher than that of the control in the gramineous-heterotic grass layer when applying phosphate fertilizer and nitrogen fertilizer according to N_ (60) P_ (60) (Table 1)
