摘要
为考察不同硫氯比的复合肥对马铃薯生长发育的影响,开展了盆栽试验。试验以纯硫基复合肥处理为对照(CK),T1~T6处理的复合肥硫氯比分别为1.5∶1、2.5∶1、3.5∶1、4.5∶1、5.5∶1、6.5∶1,测定了马铃薯的株高、茎粗、叶绿素相对含量(SPAD值)、地上部鲜质量、单薯质量及品质等指标。结果表明:与CK处理相比,当硫氯比大于2.5∶1时,对马铃薯的株高、茎粗、SPAD值、地上部鲜质量、单薯质量和品质指标等均有促进作用;在试验条件下,T2处理对促进马铃薯生长发育的效果较理想。
A pot experiment is conducted to investigate the effects of compound fertilizers with different sulfur chlorine ratios on the growth and development of potatoes.The experiment used pure sulfur based compound fertilizer treatment as the control(CK).The sulfur to chlorine ratios of the compound fertilizers in T1-T6 treatments are 1.5∶1,2.5∶1,3.5∶1,4.5∶1,5.5∶1,and 6.5∶1,respectively.The plant height,stem diameter,chlorophyll relative content(SPAD value),aboveground fresh weight,single potato weight,and quality of potatoes are measured.The results show that compared with CK treatment,when the sulfur chlorine ratio is greater than 2.5∶1,it has a promoting effect on potato plant height,stem thickness,SPAD value,aboveground fresh weight,single potato weight,and quality indicators.Under experimental conditions,T2 treatment has an ideal effect on promoting the growth and development of potatoes.
