Improve fertilizer efficiency: how to apply well
Spreading and stripting are generally applied to the farmland before the planting of the crop, or during the growth of the crop with higher density, deep application, strip application, and acupoint application are not allowed. The fertilization method can be evenly distributed to the soil tillage layer, and the early roots of the beneficial crops can be used for layering sowing before planting crops, or after the crops are planted, the ditch is about 5-10 cm deep, and the soil is covered after application.
The wheel is suitable for perennial woody crops, generally with the trunk as the center, and the wheeled fertilization ditch is excavated along the corresponding land in the margin of the upper canopy. After the fertilization, the soil can be covered, and the trunk can be intermittently dug into a symmetrical 2~4. In the crescent-shaped ditch with a certain length of rice, when a large amount of organic fertilizer is applied in winter, it is also possible to combine the cultivated land loose soil to apply fertilizer in a circular area under the canopy.
The fertilizer is dissolved in water to form a fertilizer solution, which is drenched into the soil surface where the roots of the crop are concentrated. For the phosphorus and potassium fertilizer, the base fertilizer is mainly due to the small mobility, and the method of leaching is not suitable. Can achieve the purpose of root dressing.
Spraying is mainly used for the emblem element fertilizer. It is economical to avoid soil fixation, fast nutrient absorption, high efficiency, easy to control concentration and reduce pollution. When the root absorption capacity is weak in the late crop, the leaf surface is sprayed with potassium dihydrogen phosphate. The solution can supplement the phosphorus and potassium nutrients, and has the effect of increasing the weight of the particles (phosphorus) and increasing the yield.
Apply fertilizer: look at manure
The application method of water-flooding is also called “flushing and fertilizingâ€. Generally, it is a top dressing that provides supplemental nutrition during the rapid growth of crops. Since it is supplemental fertilization, it cannot replace the main fertilization methods such as base fertilizer. However, many farmers like to use this method of topdressing. It is effective to use it. Because it can only be applied with water, urea, ammonia, ammonium sulfate and ammonium nitrate are commonly used in nitrogen fertilizer, and potassium chloride and potassium sulfate in potassium fertilizer are commonly used. Potassium nitrate can be fertilized by flushing.
Even the water-soluble phosphorus monoammonium and phosphodiammonium in the phosphate fertilizer should not be applied because the phosphate fertilizer has poor mobility and is easily fixed, and cannot penetrate into the root layer with water. The best application method of phosphate fertilizer can only be layered into the soil to improve its utilization. At the same time, it is not appropriate to break up the granular high-concentration compound fertilizer and then apply it to the non-decomposed insoluble solid organic fertilizer and microbial preparation as fertilizer.
Choose fertilizer: adapt to local conditions
The soil such as sand should be applied with organic fertilizer, such as soil and fertilizer, straw returning to the field, or planting green manure to timely pressure and fertility, and gradually improve soil properties.
The application of organic fertilizer to clay must be fully prepared for decomposing. The application of chemical fertilizer should be appropriate early, and it is advisable to “eat more mealsâ€, reduce the number of fertilizations appropriately, and avoid excessive application of nitrogen fertilizer at the end to prevent crops from being late. In addition, it is also necessary to dilute the loose soil and improve soil aeration.
The loam should be combined with long-acting fertilizer and short-acting fertilizer to meet the demand of fertilizer in different growth stages of the crop; organic fertilizer and chemical fertilizer combined with fertilizing the soil, and use heavy fertilizer; combined with a large amount of fertilizer and micro-fertilizer to provide timely crops Various nutrients.
