摘要
试验结果表明,配方施肥,培育沙棘壮苗,苗木比常规育苗营养物质提高32%。同时配方施肥使圃地的理化性质和肥力得到大幅度改善,各项生物因子指标都有较大提高。N、P、K的施肥比例应掌握在1 0.4 1。
Using formula to fertilize,the results showed that the nutritive material increased 32% than that of conventional seedling nursery.Using formula to fertilize,the physicochemical property and fertility were improved a great deal.Index of biotic factors improved greatly.Fertilizer proportion of N,P and K was kept in 10.41.
