吉农朝鲜碱茅改良盐碱地旱作栽培技术的研究

Studies on Cultural Technique of P. chinampoesis Ohwi cv. ‘Jinong' for Improve of Saline-alkali Soil

对吉农朝鲜碱茅旱作栽培采用L16(45)正交试验设计,经不同年份的重复试验,选择最佳处理组合。试验结果表明,以播种期6月20日、播种量60 kg/hm2、覆土深度0.5 cm、播种方式平条播的为最佳播种组合。

Adopting the orthogonal design L 16 （45）, the dry cultivation of P. chinampoesis Ohwi cv.‘Jinong＇ was studied. After several years revision test, the best processing combination was chosen. The results indicated that sowing time was on June 20, sowing rates was 60 kg/hm^2, covering thickness was 0.5cm, and the best sowing method was flat strip-sowing.
