稻草还田技术在攀枝花大棚苦瓜中的应用研究

Application Effects of Rice-straw Returning Technology on Greenhouse Bitter Gourd in Panzhihua

研究了不同稻草还田量、腐熟剂的用量对土壤有机质含量、养分含量、苦瓜产量及品质的影响。试验结果表明,施用稻草的处理(处理1、处理2、处理3)比处理4(CK1,空白对照)土壤有机质含量平均增加56.3%,速效钾平均增加55%;施用腐秆剂土师傅5号的处理(处理2、处理3)比处理1土壤有机质含量平均增加30.1%,碱解氮平均提高63.2%;稻草还田能从一定程度上增加苦瓜产量,但对苦瓜的生长发育及苦瓜的品质没有较大影响。

In the paper, we studied the effects of different amounts of returning rice straw, decomposition agent on soil organic matter content, nutrient contents and yield and quality of bitter gourd. The results showed that, compared to the control treatment （CKI）, soil organic content and available potassium content of the treatments applying rice straw （T1, T2, T3） increased by 56.3% and 55% respectively. The soil organic content and available nitrogen content of the treatments applying decomposition agent Tushifu No.5 （T2, T3） were 30.1% and 63.2% higher than those of Tl. Returning rice straw to soil made the yield of bitter gourd increased to some extent, but it had no significant effect on growth, development and quality of bitter gourd.
