Hydroseeding machine grass seed

2019-07-31 09:39:16

The technique of spraying grass on the soil is to create a matrix layer on the rock slope that can grow and not be washed. Then the plant seeds are sprayed on the substrate layer, and the vegetation is restored after the later maintenance. This practice is now introduced to everyone.

Guest Soil Spraying hydroseeding machine Material Preparation Matrix Material Selection and Proportioning Composition Matrix materials mainly include guest soil, organic matter, chemical fertilizer, water retaining agent, binder, pH buffering agent etc.

The land is suitable for local conditions, it is best to choose loam and loess. The soil should be dried, sieved, and sieved from 1.5 cm to 2 cm to remove large soil particles and other debris. The soil fertility and cohesiveness are poor, and should not be used as much as possible; the soil with excessive viscosity can improve its permeability by increasing the content of organic matter.

The organic matter commonly used in organic matter is sawdust and rice husk, which are inexpensive and easy to obtain.

Chemical fertilizers are used in combination with organic fertilizers and compound fertilizers to provide the longest supply of fertilizer for plant growth.

The water retaining agent has a high rate of water absorption property, can effectively absorb and store water, and slowly releases moisture during drought to provide seed germination and growth of plant seeds. The amount of water-retaining agent can be more or less depending on the amount of local precipitation. The place with more precipitation can be placed less, and the place with less precipitation can be placed more, usually 3 grams per square meter.

The binder is added to the matrix of the binder and the pH buffer matrix to form a stable whole matrix layer (thickness about 10 cm) and the slope of the rock to prevent the erosion and erosion of the matrix layer by the rainwater. The commonly used binder is ordinary Portland cement. . The amount of cement must be properly controlled. Too much soil layering and hardening of the matrix layer, the plant can not grow normally, too little adhesion is not enough, the matrix layer is easily eroded by rain, washed, and even the matrix layer collapses. The main factors affecting the amount of cement are: slope size, physical structure of the guest soil, and the amount of precipitation. The slope of the rock slope is large, the viscosity of the guest soil is poor, and the precipitation is much. The amount of cement should be appropriately increased; otherwise, the amount of cement should be appropriately reduced.

The main role of plant seed selection and matching grass slope planting is to prevent soil erosion, restore vegetation, and increase the effect of greening landscape. Therefore, the following points should be considered in the selection of plant species: plant species should be selected from the selection of excellent and adaptable species. The selection of plant species requires strong drought resistance, rapid growth and robustness, and the roots are developed deep into the soil. It is resistant to thinness and can adapt to the harsh growth conditions of slopes and consider its landscape performance on the basis of adaptation.

The combination of fast-growing and slow-growing, through plant proportioning design, achieves the combination of fast-growing and slow-growing of seed plants, thus forming ground cover as quickly as possible on the one hand, and achieving long-term development of vegetation on the other hand.

The landscape effect of urban rock slope greening requires not only the four seasons of green grass, but also shrubs. In order to increase the greenness of the slope in the cold season, it is necessary to add a certain proportion of cold-season grass species (such as tall fescue and high dormant mites) to the selection and ratio of plant seeds; at the same time, reduce the highly invasive Bermudagrass. The amount of seeds, because the hay formed by the Bermudagrass into the dormant period is a deficiency of the winter landscape.

In order to control the turf grass growing too fast and growing too high, we use plant growth regulators on the turf grass in Chengping. The paclobutrazol 500PPm was sprayed evenly once, and the tall fescue and Baixi grass branches were thick and short, and the stems of the dog's roots grew slowly and the branches increased. When the turfgrass grows vigorously, the effective control time is usually about 30 days. Similarly, plant growth regulators also affect the growth of shrub seedlings in plant communities, which is undesirable. Therefore, the concentration and frequency of use of plant growth regulators should be carefully considered.
