| 摘 要： | 通过两年在几种不同土壤上所进行的田间试验及盆栽试验,表明合理施用化学钾肥对马铃薯块茎的产量、品质以及对马铃薯的抗病性均产生有利影响。但其肥效与土壤速效钾含量及农肥中草木灰的数量有关。一般当土壤速效钾(K)大于30mg/100g±或所施农肥中含有大量草木灰时肥效就不明显。

A Study on the Effects of potassium Fertilizer Application on potato |
| |
| Abstract: | The pot and field experiments in different kinds of soil have been made for two years in our provience.The results show that reasonable application of chemical potassium fertilizers have given good effects on the yield and quality of potato tuber and have increased the disease resislance of the plant.And these effects are related to the content of rapidly available potassium in the soils and the quantity of plant asia in the manure applied.Generally,when the content of rapidly available potassium in the soils is more than 30mg k/100g soil or there is a huge amount of plant ash in the manure applied,the efficiency of chemical potassium fertilizers is not so obvious. |
