The Effect of Synchronous Side Deep Fertilization on Rice Yield and Economic Benefits of Bowl Seedling Wide and Narrow Row Machine Insertion
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 synchro-nous 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 synchro-nously and deeply on the side of the narrow row of bowl seedlings increased the average yield by 5-12 kg/667 m2,and the average income increased by 60-80 yuan/667 m2,with the best economic bene-fits.It is recommended to carry out experimental demonstration and promotion.
