Description
Technical Field
The invention belongs to the field of plant planting, and relates to a plant fertilization method under landscaping and crop cultivation. In particular to a base fertilizer application method for greening and water and soil conservation plant measures. The fertilizer has the advantages of wide application range, balanced and long-acting fertility, safety, environmental protection, low material cost, investment saving, simple manufacture and short construction period, and is particularly suitable for plant measures of ecological slope protection and greening.
Background
At present, in the crop and plant planting industry, a base fertilizer is taken as the most main fertilizer, and generally accounts for 70-80% of the total fertility, and the base fertilizer application modes mainly comprise a ditch burying method, a dot hole burying method and a 'one-pass cleaning' fertilization method. The base fertilizer is generally an organic fertilizer or a mixed fertilizer of an organic fertilizer and an inorganic fertilizer. The 'one-step cleaning' fertilization method is adopted, namely a full-layer fertilization method which is used for fully mixing soil and fertilizer by applying all base fertilizer once when the field is finished. The method is suitable for paddy fields with strong fertility preservation such as clay, heavy loam and the like, and is not suitable for dry lands for cultivating and weaving soil. Although the straws (including corncobs) are used as an organic base fertilizer in the process of returning waste organic fertilizers to the field for comprehensive utilization in the aspects of soil improvement, environmental protection, continuous development and the like, the straws have poor effect due to the reasons of high C/N ratio, difficulty in rotting, large turning pressure, insufficient nitrogen fertilizer and the like. Particularly, when the slope is treated and greened in the industries of water conservancy and hydropower, highways, railways, mines, port and navigation and the like, a mode of combining spray-seeding base materials with 'one-pass clear' fertilization is mostly adopted, namely, the fertilizer and other spray-seeding base materials are sprayed out by a spray-seeding machine, the thickness of a sprayed soil base layer is small and is generally only 10 cm-15 cm, the fertilizer mixed in the spray-seeding base layer is easy to lose (such as hydraulic spray-seeding and soil dressing spray-seeding) in dry land with slope, and even if the loss is small (such as high-order granule spray-seeding), the local fertility of the plant is too heavy, so that the problems of 'one year green, two years yellow and three years dead light' occur, which mainly violates the principle of low-concentration fertilizer supply of the ground-cover plants and balanced fertilizer supply of shrub plants. In addition, the slow release nutrition rod technology used in the water and soil conservation industry is expensive, can only adopt the arrangement of separation points, has generally larger spacing (measured by meters), larger area of a fertilizer-free area and heavier fertility of a fertilizer area, and adopts the arrangement of drilling holes on a rock surface in a spray seeding base layer with small thickness, thereby increasing the construction difficulty.
