混合基质条件下茄子苗期施肥量研究

Studies on Fertilizer Application Levels of Seedling Stage of Eggplant Raised with Mixed Media

在混合基质（草炭、蛭石、炉渣灰）育苗条件下，随着施肥量增加，茄子幼苗生长、干物质积累以及植株对Ｎ、Ｐ、Ｋ的吸收量也随之增大。当施肥量达到２８００ｇ／ｍ３时，茄子幼苗的株高、干物质积累以及Ｎ、Ｐ、Ｋ吸收量均达到或接近最大值，因此。

When eggplant seedlings were raised in mixed media (peat, vermiculite and cinder), the plant growth, dry matter accumulation and uptake amount of nitrogen, phosphorus and potassium increased with fertilizer application levels. The plant height, dry matter accumulation and uptake amount of nitrogen, phosphorus and potassium were nearly maximum when the fertilizer application level reached 2800g /m￣3.Therefore, 2800g/m￣3 was optimum for raising seedlings with mixed media.
