- 摘要:
- 为大幅度减少灌溉水量的浪费,减轻农民负担,促进农民增收,以空育131为材料,比较研究了其在不同灌溉方式下的农艺性状。结果表明:在控灌和浅湿干灌溉下,空育131根系发育好,茎叶生长协调,株高、穗长、穴数和穗数等农艺性状优于常规灌溉处理;水稻控灌和浅湿干灌溉用水量分别为6 900和8 625 m3,比常规灌溉节水34.3%和17.9%;控灌和浅湿干灌溉相对常规灌溉,有利于叶片的光合作用和干物质积累,增产分别为4.4%和1.4%,控灌增产376.50 kg?hm-2,直接经济效益增加975.00元?hm-2。因此,节水技术的应用不仅大大节约了田间用水量也可带来较好的经济效益。
- Abstract:
- To substantially reduce the waste of water irrigation to alleviate farmers’ burdens,increase farmers’ income,Kongyu 131 was used as tested material,the comparative study on agronomic traits under different irrigation methods was conducted.The results showed that:in Control irrigation and Shallow-wet-dry irrigation modes,the roots developed well,stem leaves grew harmonious,plant height,panicle length and panicles number and other agronomic characters were better than those of General irrigation treatment;The water volume of Control irrigation and Shallow-wet-dry irrigation respectively for 6 900 and 8 625 m3,saving water 34.3% and 17.9% than General irrigation;Control irrigation and Shallow-wet-dry irrigation treatment were good for leaves of photosynthesis and dry material accumulation,yield increasing respectively for 4.4% and 1.4%,Irrigation treatment could increase yield by 376.50 kg?hm-2,direct economic efficiency increased about 975.00 Yuan?hm-2.Therefore,application of water-saving technologies had not only greatly reduce the field water consumption,but also bring good economic benefits.
