The correct method for broadcasting compound fertilizer during the rice stem elongation stage
During the rice stem elongation stage, topdressing is generally carried out 1 to 2 times. In previous years we used urea, but this year we switched to a high-tower granulated fertilizer. This is a compound fertilizer with high nitrogen and low phosphorus and potassium. The fertilizer granules are round and smooth on the outside, with holes inside, and have a relatively low specific gravity. Before fertilizing, we first drained the flooded water, then broadcast the compound fertilizer granules on the soil surface, and immediately let water back into the field. After the water layer was full, we found that some fertilizer granules appeared on the water surface. These floating granules were blown to one side by the wind, and some stayed in the sheltered corners.

Key Operational Points for No-Till Rice Seedling Broadcasting Cultivation Technology
No-till rice seedling broadcasting refers to a new rice tillage and cultivation technique in which, after harvesting the previous crop, without any plowing or harrowing of the paddy field, herbicide is first applied to kill weed plants and shed-grain seedlings and to wither rice stubble, then the field is irrigated and fertilized for retting, and after the water layer naturally drains or shallow water is released, plastic-tray seedlings or paper-tube seedlings are broadcast-transplanted into the main field...

Key Technical Points for Controlling Diseases, Pests and Weeds in the Field After Rice Seedling Broadcasting
Southern rice black-streaked dwarf disease is a viral disease mainly transmitted by the white-backed planthopper. It mainly harms staple grain crops such as rice and corn. Once a crop is infected, the plant becomes stunted, tillering increases, and in the later growth stage the diseased rice cannot head or set grain, sometimes resulting in a complete loss of harvest, seriously threatening the safety of our county's grain production. In order to scientifically...
