摘要
为了促进谷子的大面积推广种植,加速谷子产业化开发,对化控间苗谷种栽培技术进行了研究。结果表明:谷种化控间苗效果与土质、肥力、整地质量、土壤墒情和播期等因素有关。不同栽培条件下,通过调节配比或播量可以达到化控间苗目的,实现谷子不间苗或少间苗。土壤黄褐墒情(含水量15%～18%)和春播谷子,采用配比35%、播量15.00 kg/hm2,或配比50%、播量11.25 kg/hm2;土壤黄墒情(含水量13%～15%)和夏播谷子,采用配比50%、播量15.00 kg/hm2,或配比50%、播量11.25 kg/hm2;红土壤及有机质含量高的土壤,化控间苗谷种的配比或播量应适当低于一般壤土地(含瘠薄地)。
To promote the planting of millet in large scale,and speed up its industrialization development,the cultivation techniques of thinning out by chemical control were studied.The results showed that the technique was influenced by soil texture,fertility and moisture,site preparation quality,and sowing date.Thinning out by chemical control could be realized through adjusting the proportion of untreated seeds and sowing rate.When the soil moisture was 15%-18% during spring sowing,the proportion of untreated seeds was 35% with the sowing rate of 15.00 kg/hm2,or 50% with the sowing rate of 11.25 kg/hm2.When the soil moisture was 13%-15% during summer sowing,the proportion of untreated seeds was 50% with the sowing rate of 15.00 kg/hm2,or 50% with the sowing rate of 11.25 kg/hm2.The proportion of untreated seeds and sowing rate on red soil and soil with high organic matter content should be lower than those on loam.
