Scientific application of panicle and grain fertilizers is a guarantee for rice to obtain high yield, high quality and high efficiency. According to tests, it is possible to increase rice production by 20% to 25% by using panicle and grain fertilizers. Rice panicle fertilizer refers to the period of young panicle differentiation before heading, and timely applying a certain amount of available nitrogen fertilizer will help consolidate the effective tillering in the early stage, reduce and prevent the degradation of spikelets, and promote good development of rice panicles. Due to differences in fertility, cultivated varieties, and meteorological conditions of paddy fields, the timing and methods of top-dressing are different. Generally, the top dressing time is suitable for differentiation from branch to spikelet differentiation stage, about 16-18 days before heading, or rice leaf age index of 90%. The flag leaf of rice is just exposed and the young panicles grow to 1-2 mm. The amount of topdressing fertilizer per acre is: if ammonium nitrate is used, 4–5 kg, if ammonium sulfate is used, it is 6 kg. If using ammonium phosphate, it needs 4–5 kg. Before topdressing, irrigation 3 to 5 cm deep, plugging up and down the mouth, evenly spread, 4-5 days and then turn into a normal tube. In the case of rainy days, rice fields growing too busy may not chase panicles. Rice grain fertilizer refers to a small amount of fertilizer that is applied 5 to 10 days after the ear, or a fertilizer that is applied two to three days before the head of the rice cracks. Appropriate application, can make the grain full, 1000-grain weight increase; improper application, no effect or late-maturing lust, affect the yield. In order to apply granulated fertilizer, we must do a "three look", that is, look at the sky, see the fields, and see the seedlings. To see the sky is to grasp the weather, when it is necessary to work in the drought, and to use less rain. Watching the field is to grasp the soil fertility of different plots, to make more thin fields, and to use less fertilizer. Look at the seedlings according to the seedling condition, the growth is thin and weak, the yellow color of the leaf color after heading is severe, the growth is strong, and the yellowing of the heading is lightly applied or not applied. Granular fertilizer is generally applied ammonium sulfate, urea and other fertilizers, applied 3-5 kg ​​per acre. At the time of application, the field should be filled with shallow water. Do not apply water after fertilization and allow it to dry naturally. If there is no urea, ammonium nitrate can also be applied. In addition to doing topdressing, it is also possible to use extra-foliage dressing. The methods are: 1. Foliar spraying urea at a concentration of 1%, applying 5 kg per hectare. 2. The foliar potassium dihydrogen phosphate solution was sprayed at a concentration of 0.5% and 2.5 kg per hectare.
