忻城珍珠糯玉米密植高产栽培与害虫防治

High Density and High Yield Cultivation and Pest Control on the Pearl White Waxy Corn in Xincheng

摘要: 忻城珍珠糯玉米作为国家地理标志的玉米品种，品质独特，但是产量难以提高。经过笔者实践探索，总结出一套密植高产栽培技术，在广西来宾市忻城县果遂镇和兴宾区试验示范，通过育苗移栽、定向密植、药物控制植株徒长措施、加强病虫害防治等技术措施，达到高产的目的。应用该技术平均每667 m²产干玉米粒356.43 kg，比普通种植方法(254.72 kg)增产39.93%，增产显著。

Abstract: Xincheng pearl white waxy corn, a national geographical indication product, has peculiar traits, but there has hardly been any improvement in its yielding capacity. The writers carried out practical explorations. The high density and high yield cultivation technology system was consequently established, which has been piloted and demonstrated at Guosui Township and Xingbin District in Xincheng County of Laibin City of Guangxi Region. A combination of technical approaches, including seedling transplanting, oriented high density planting, chemical control of excessive growth and the pest control was used to improve corn yield. The results showed that the average yield of dried corn kennel was up to 356.43 kg per 667 m², 39.9% higher than the traditionally cultivated corn (254.72 kg). The result in increasing yield was obvious.
