磷营养对克新1号和夏波蒂品种马铃薯的抗旱性效果对比分析

Comparison and Analysis on Effect of Phosphorus Nutrition on Drought-resistance of Potatoes of the Kexin 1 and Shepody

提高植物的抗旱性一直是农业科学中研究较为热门的课题,本文通过对马铃薯作为研究对象,选取克新1号和夏波蒂两个较为典型的品种,通过施加不同浓度的磷肥来研究磷营养对克新1号和夏波蒂马铃薯的抗旱性效果。结果表明,磷肥可以显著提高两个品种马铃薯的抗旱性能,但是需要在一定的适宜浓度范围内。并且,磷肥对于提高两个品种马铃薯叶片中叶绿素的含量,并无显著效用。

Increasing drought resistance of the plant has been more popular in agricultural scientific research subject, thisarticle used potatoes as the research object, and selected Kexin 1 and Shepody two more typical varieties, by applyingdifferent concentrations of phosphate fertilizer to study the effect of phosphorus nutrition on drought resistance of two kindsof the Kexin 1 and Shepody. The results showed that phosphate fertilizer can significantly improve the drought resistanceperformance of two varieties of potatoes, but it need in a certain concentration range. And phosphate fertilizer can improvethe two varieties of potatoes chlorophyll content in leaves, has no significant effect.
