不同施肥方式对马铃薯生长及产量的影响

以‘冀张薯8号’为材料,研究不同施肥方式对马铃薯的生长和产量的影响。结果表明:在不同时期处理f7、f4叶片的SPAD值均大于其它处理,施氮肥t越高SPAD值越大,磷肥和钾肥的施入对SPAD值的影响较小;氮、磷、钾肥对马铃薯不同时期株高增长的影响有所不同,从日平均增长量来看,处理t7最高,而后依次为f4、f6、f3、f5、f2、f1;马铃薯产量以处理f7产量蕞高,f4次之,方差分析表明。两处理与其它处理相比表现为极显著,在磷钾不变的情况下,随着氮肥使用量的增加,产量也随之增加。...

A fidd experiment was conducted to evaluate the effects of different fertilization methods on growth and yield d potato, by using the variety Jizhangshu No. 8 under seven treatments (f1 ,f2 f3 ,f4,tS ,f6 ,f7) and five growth stages. The results showed that the plant height and SPAD readings were higher for the f7 treatment. After the harvest, the yield of f7 and f4 treatments reached extremely significant level compared with other treatments. Nitrogen fertilizer could increased the yield,height and SPAD readings,but P and K fettlhzer were not obvi- ous to improve the indexes. Therefore, the f7 treatment could improve potato production.
