摘要
以小区试验的方法选择典型的南方旱坡地土壤,通过施用不同用量的酸性土壤改良剂在花生上的应用效果试验,探讨旱坡地土壤施用酸性土壤改良剂的改良效果及最佳用量。结果表明:施用改良剂可增加花生主根的长度和地上部分的生物量;与不施用改良剂比较,酸性土壤改良剂对旱坡地花生具有显著的增产效果,增幅为9.5%～19.6%;同时可提高花生果实的品质,增加花生果仁中粗脂肪和粗蛋白含量,增加幅度分别为2.6%～5.2%、0.3%～2.8%。结合花生的产量、植株营养状况、生长发育指标、品质分析等综合考虑,酸性土壤改良剂在旱作花生上适宜推荐使用量为每667 m2 60～65 kg。
A plot experiment of the peanut application effect with the different amount acid soil amendment was conducted to test the improvement effect and the best amount used on sloping-land in south.Results showed that compared to the treatment without the acid soil amendment of the sloping-land peanut,the length of the peanut main root and the biomass were increased by using the acid soil amendment,which were significantly increased from 9.5% to 19.6%.Furthermore the fruit quality,the crude fat and the thick protein content of the peanut was respectively increased from 2.6% to 5.2% and from 0.3% to 2.8%.Combined the output,the plant nutritional status,the growth target and the quality analysis of the peanut,the recommendation amount of the acid soil amendment on the sloping-land peanut was 60～65 kg per 667 m2.
