1, one-time fertilization method: one-time fertilization method is a one-time fertilizer as a base fertilizer in the whole layer when plowing, after no longer fertilize, this fertilizer method is characterized by simple labor, can promote early-onset, but easy late Premature senescence is mainly suitable for early rice turning autumn, double cropping rice field with short growing period in field, rice field with strong fertilizer holding capacity and organic fertilizer, sand field is generally not applicable, slow-release fertilizer and controlled-release fertilizer and machine organic complex Fertilizer can use this method of fertilization. 2, before the promotion, in the control, post-supplementation method: This fertilizer method is characterized by focusing on early fertilization, emphasizing the mid-term nitrogen control, in order to facilitate fertility transformation, appropriate late application of fertilizer, rice in the fertility of high, medium-term easy crazy The plots are more suitable and are more widely used in production. 3. Pre-stabilization, mid-promotion and post-protection fertilization methods: The characteristics of this fertilization method is to reduce the amount of fertilization in the early stage based on the basic seedlings inserted, so that the rice grows steadily, and the medium-term heavy panicle fertilizer promotes large panicles and grains. Appropriate application of granulation fertilizer at late stage to increase seed setting rate and grain weight can meet the fertilizer demand of rice at different growth stages. It is a high-yield, super-high-yield fertilization technology developed in recent years. It is suitable for high-yielding fields, and its disadvantage is that Many times, it is difficult for farmers to grasp. 4, anhydrous layer fertilization method: This fertilization method is characterized by fertilizing the field when the water is dry, the general basal fertilizer after the dry ploughing, dry land preparation, so that the soil and fertilizer blending, field fertilizer when the field is dry, slowly irrigation after application, The use of fertilizers to bring the fertilizer into the soil, the advantage of this fertilization method is that it can reduce the loss of fertilizer and increase the utilization of fertilizer. 5, foliar dressing fertilization method: This fertilization method is characterized by fertilizer is not directly applied to the soil, but by spraying on the foliage, the leaf surface absorption for the growth of rice needs, its advantage is that the amount of small, fast absorption, The effect is obvious and the fertilizer utilization rate is high. The disadvantage is that it is more labor-intensive. It is generally combined with spray spraying and spraying. It can be sprayed during the whole growth period, spraying more at the booting stage and filling stage, and is particularly suitable for the application of trace element fertilizers. The application of rice is promoted after recovery.
