| 摘要: |
| 为了确定紫色土壤种植花生的高产高效施肥,于1996年~1997年在广西邕宁县进行花生施肥试验。试验设有机肥、尿素、氯化钾和钙镁磷肥4个处理,总面积480.24 m2。结果表明,有机肥或尿素的过量使用是植株徒长倒伏的主要因子;增施:有机肥≤ 15000 kg/hm2,尿素≤ 150 kg/hm2,KCl ≤ 225kg/hm2,钙镁磷肥≤ 450 kg/hm2,都能明显提高花生的单株生产力、百果重和百仁重,其中有机肥和尿素的效果极明显。 |

| Abstract: |
| The fertilization experiment of peanut was conducted in purple soil in 1996 to 1997 in Yongning county of Guangxi in order to predominate the effective fertilizing of getting high yield in peanut in purple soil.The treatments of this experiment included organic fertilizer,urea,potossium chloride and fused calcium magnesium phosphate.The test areas was 480.24 m2.The results were as follows:the excessive amount of organic fertilizer or urea was the cause of plant spindling and falling over. Application of different fertilizers for organic fertilizer ≤ 15000 kg/hm2,urea ≤ 150 kg/hm2,KCl ≤ 225 kg/hm2,fused calcium magneium phosphate ≤ 450 kg/hm2,have the apparent effects on increasing the individual plant productivity,the weight of one hundred granule and the weight of one hundred kernel.Organic fertilizer and urea showed more apparently effects. |
