设计4种营养土配比试验，选出最优的营养上配比组合，并对影响产量的构成因素进行分析，结果表明：20％EM堆肥＋60％田土＋20％草炭＋纯N0．2kg／m3＋K2O0．12kg／m3＋P2O50．2kg／m3配比组合最好，产量最高，使单穗粒重、粒数、百粒重有明显提高。另外，EM堆肥可提高土壤速效性养分当季利用率，K最明显。
The results showed that: 20% EM composting + 60% field + 20% peat + pure N0.2kg / m3 + K2O0 .12kg / m3 + P2O50.2kg / m3 the best combination of the highest yield, the grain weight per spike, grain number, weight of 100 significantly increased. In addition, EM composting can improve soil seasonal availability of nutrients quarterly, K the most obvious.
