摘要
N、P、K三要素的不同配比施肥试验表明，不同配比的肥效显著不同，油茶产量差异很大。本试验以N、P、K的配比为1：2：2（单株施肥是0．75kg）的产量最高，效果最好．不同配比对油茶春梢生长、花芽及叶片数的增长均不一样，与产量的变化也不一致。对果的经济性状影响不大。最佳配比的增产效益高达11倍。
Major fertilizers of N, P, K were applied to oiltea camellia,Camellia oleifera,stands by differently-proportioned combinations. Results showed that both the fertility and thefruit yield varied markedly with the combination. The best effect was obtained when the propor-tional combination of N:P: K was 1: 2: 2 and the per-tree dosage was O. 75 kg. However, it wasalso found that the economic characters of the fruit was not significantly affected by fertilizercombinations. The best proportional combination brought about a yield increase 11 times higherthan the check.
