Net turf taking agricultural waste and silicate minerals as matrixes and preparation method thereof

Abstract

The invention discloses a net turf taking agricultural waste and silicate minerals as matrixes and a preparation method thereof. The net turf sequentially comprises a substrate layer, a protective layer, a matrix layer and a grass stem layer from bottom to top; the protective layer comprises straw or coconut fibers; the matrix layer comprises silicate mineral particles and an organic fertilizer; and a lower net is arranged at the lower part of the protective layer. The net turf disclosed by the invention has the advantages of light weight, high turf forming speed, short outplanting period, few weeds, strong tensile resistance, difficulty in breaking and the like, does not damage cultivated land, protects a plough layer, is simple and convenient to operate, has high production efficiency, facilitates large-scale mechanical operation, and is suitable for planting various playgrounds and urban greenbelt lawns. The preparation method of the net turf is simple and convenient in process, low in cost and suitable for large-scale actual production.

Description

technical field [0001] The invention relates to a turf, in particular to a net turf based on agricultural waste and silicate minerals and a preparation method thereof. Background technique [0002] At present, there are two main methods of turf production: soil lawn and sand lawn. The soil lawn is the turf directly planted and produced by using the original soil of the farmland. Because the surface soil is taken away during the transplanting process, the cultivated layer is destroyed, resulting in nutrient loss, and the soil fertility declines year by year; and the quality is heavy, so it is not easy to transport. With the promulgation of a series of national policies prohibiting the destruction of the cultivation layer in recent years, some areas use sand flats instead of soil lawns for turf production. Sand flats have the advantage of not destroying the soil cultivation layer, but they have poor water and fertilizer retention and require a large amount of water and fertili...

Because the surface soil is taken away during the transplanting process, the soil turf destroys the cultivated layer, resulting in nutrient loss, and the soil fertility declines year by year; and the quality is heavy, so it is not easy to transport

With the promulgation of a series of national policies prohibiting the destruction of the cultivation layer in recent years, some areas use sand flats instead of soil lawns for turf production. Sand flats have the advantage of not destroying the soil cultivation layer, but they have poor water and fertilizer retention and require a large amount of water and fertilizer. In addition, in recent years, due to the shortage of resources, the price of sand has risen, and the production cost of sand turf has increased year by year, and the cost performance is not high.
