| 中文摘要: |
| 不同氮肥用量对金秋梨产量及品质的影响试验结果表明,金秋梨的产量与氮肥间有一定的正相关关系,氮肥用量越大,金秋梨的产量越大。随着氮肥用量增加，金秋梨硬度不断降低，总糖含量和Vc含量逐渐增加，但对总酸含量影响较小。通过对经济效益进行分析，发现氮肥投入量越大，净收入越多。综合考虑经济效益和氮肥可能对环境带来严重的危害，推荐中氮施肥处理作为贵州黔东南地区的推荐施肥量. |
| 英文摘要: |
| The effect of N application rate on yield and quality of jinqiu pear was studied. The result showed that the effect of N
application rate on yield was very significant, and the yield of pear increased with N application rate increasing. The correlation between N application rate and quality of pear was affirmatively existed. Hardness reduced, total sugar and Vitamin C concentration improved with N application rate increasing. However, the effect of N application rate on total acids was very marginal. The net income increased with N application rate increasing by analyzing economic benefit. We advocated optimum N application rate as optimal N fertilizer in the southeast of Guizhou province after considering synthetically the economic benefit and the potential risk of exceeding N application. |
