钵苗宽窄行机插同步侧深施肥对水稻产量及经济效益的影响

The Effect of Synchronous Side Deep Fertilization on Rice Yield and Economic Benefits of Bowl Seedling Wide and Narrow Row Machine Insertion

本试验以水稻钵苗宽窄机插秧为载体,在贵州不同海拔、不同水稻生态区,开展水稻钵苗宽窄行机插同步侧深施肥、水稻钵苗宽窄行机插传统施普肥、水稻钵苗宽窄行机插一次性人工撒施缓释肥,三种不同施肥方式对比试验,探索钵苗宽窄行机插同步侧深施肥对水稻产及经济效益的影响。结果表明,钵苗宽窄行机插同步侧深施缓释肥水平均增产5~12 kg/667 m^(2),平均增收60~80元/667 m^(2),经济效益最好,建议开展试验示范推广。

This experiment used rice bowl seedling wide and narrow row machine transplanting as a carrier,and carried out synchronous side deep fertilization of rice bowl seedling wide and narrow row machine transplanting,traditional application of general fertilizer for rice bowl seedling wide and narrow row machine transplanting,and one-time manual spraying of slow-release fertilizer for rice bowl seedling wide and narrow row machine transplanting in different altitudes and rice ecological areas in Guizhou.Three different fertilization methods are compared to explore the impact of synchronous side deep fertilization of bowl seedling wide and narrow row machine transplanting on rice yield and economic benefits.The results showed that the slow release fertilizer and water applied synchronously and deeply on the side of the narrow row of bowl seedlings increased the average yield by 5-12 kg/667 m^(2),and the average income increased by 60-80 yuan/667 m^(2),with the best economic benefits.It is recommended to carry out experimental demonstration and promotion.
