目的 研究新型植物源有机药肥(烟渣有机药肥和茶皂素有机药肥)在水稻上的肥效以及对水稻害虫的防治效果,促进水稻栽培过程中化肥、农药双减的实现。方法 水稻田间试验设计3个处理:常规施肥(对照)、烟渣有机药肥+80%常规施肥、茶皂素有机药肥+80%常规施肥。测定水稻产量,分析水稻稻谷、秸秆养分吸收以及土壤速效养分含量,并在水稻分蘖期调查有机药肥对稻纵卷叶螟Cnaphalocrocis medinalis和白背飞虱Sogatella furcifera的防治效果。结果 与常规施肥相比,烟渣有机药肥和茶皂素有机药肥的部分替代施用分别提高水稻产量22.29%和18.58%,稻谷N、P和秸秆K吸收量显著提高,水稻收获后的大田土壤速效养分含量无显著差异。植物源有机药肥对稻纵卷叶螟和白背飞虱有明显的防治效果,其中烟渣有机药肥和茶皂素有机药肥对稻纵卷叶螟的防效分别达到81.27%和51.09%,对白背飞虱的虫口减退率分别为55.74%和37.70%。结论 施用新型植物源有机药肥能部分替代化肥并减少化学农药的使用,增加水稻产量,减少虫害,促进农业可持续生产。 相似文献

Rice ratooning refers to the production of second crop from the stubble after the harvest of main crop.Main and ratoon rice growth and development are affected by different factors.These factors include varieties selection,water management,fertilizer management,stubble height,plant protection practices and external environmental factors such as temperature and light.In this review,we discussed the different factors affecting the yield and yield components of main and ratoon rice.Among these factors the most important and first one is varietal selection.Varieties should be selected according to the requirement of specific area and prefer varieties resistant to insects/pests and diseases.Sufficient amount of water and fertilizer should be supplied.Stubble height of 10-20 cm will resulted in high production of ratoon rice.Too low or too high temperature and light would reduce the grain yield and quality of rice.Optimal temperature is useful for higher yield.It was concluded that by keeping the management practices more efficiently,the yield of main rice as well as ratoon rice could be increased.There is a need of more studies focusing on improvement of the quality of ratoon rice. 相似文献
