滴灌下不不同供磷方式对马铃薯生长的影响
Effects of P Application Methods on Growth of Potato under Drip Fertigation
摘要
Abstract
A pot experiment was carried out to evaluate the effects of P fertilizer application methods on the growth,tubers yield and quality of potato under drip fertigation system.The results obtained were as follows:under this experiment condition,compared with no phosphate fertilizer treatment,the phosphate treatment could significantly increase hiomasses of potato,then there had no different among the five treatments in phosphate application methods.The P fertilizer applied by drip fertigation increased P concentration in potato tuber compared with basal application. Tuber yield of the treatment of 50％ P basal application and 50％ P application by drip fertigation with ten times were higher than the other treatments,andthe commodity rate was the higher too,the data as 88.96％. The content of starch and dry matter had no difference among the five treatments in P application methods.关键词
