摘要
采用正交试验法,对青花菜无土育苗基质中的最佳施肥量进行了研究。结果表明,适量增施氮肥可显著促使幼苗生长、干物质积累和对养分的平衡吸收,青花菜无土育苗的最佳施肥量每立方米为:N0.4 kg、P2O50.4 kg、K2O 0.1 kg。
The optimum rate of fertilize in soilless nursery substra for broccoli were studied with orthogonal design. The results showed that growth, dry matter accumulate and nutrient absorption of broccoli seed increased with proper increment of nitrogen supply. The optimum rate of N, P2O5, and K2O in soil substrate for broccoli seedling were 0.4 kg/m^3, 0.4 kg/m^3, and0.1 kg/m^3, respectively.
