青铜峡灌区优质水稻主要栽培方式比较研究

Comparative Study of Main Cultivation Methods for High-quality Rice in Qingtongxia Irrigation Area

对青铜峡灌区优质水稻主要栽培方式进行比较研究,通过田间试验表明,机插秧比人工插秧增产8.1%,效益增加17.1%;幼苗旱长比播后上水增产14.7%,效益增加16.3%。机插秧从种到收便于实现标准化控制,适合涉农企业及种粮大户对水稻的栽培选择。水稻种植户在选择幼苗旱长栽培时,应看土壤墒情而定,如果土壤墒情不好,选择播后上水栽培方式较为稳妥。

A comparative study of the main cultivation methods for the high-quality rice in Qingtongxia irrigation area is conducted. The field testing showed that the yield of the rice transplanted with transplanter was 8.1% higher than that with artificial transplanting and the benefit increased by 17.1%. The yield with seedling dry growth was 14.7% higher than that with irrigation after sowing and the benefit increased by 16.3%. The transplanting with transplanter was convenient for realizing standardized control and was suitable to be selected by the agriculture-related enterprises and the large-size grain growing households. When the seedling dry growth is selected by the rice growing households, the soil moisture should be considered. If the soil moisture is not good, the cultivation with irrigation after sowing should be selected for prudence.
