Special stress-resistant golf turfgrass fertilizer and preparation method thereof

Abstract

The invention discloses a special fertilizer for stress-resistant golf turfgrass. The special fertilizer comprises the following components: 35-43 parts of nitrogen fertilizer; 8 parts of phosphate fertilizer; 13.5-20 parts of a potash fertilizer; 11 to 13.5 parts of trace elements; 22 to 26 parts of an auxiliary agent; according to the invention, the disodium ethylene diamine tetraacetate which has stability and chelating property is adopted, so that medium trace elements can be effectively guaranteed and activated, the absorption of metal nutrient elements by a lawn in an extreme environment is facilitated, and the nutrient deficiency phenomenon of the lawn is solved; fulvic acid, protein peptide and sugar can be directly absorbed by lawns and supplied to various enzyme activities in bodies, so that the anabolic ability of the lawns is enhanced, the growth of the lawns is promoted, especially the openness of leaf surface pores of the lawns can be properly controlled, transpiration is reduced, the fulvic acid, the protein peptide and the sugar play an important role in drought resistance, and the stress resistance can be improved; the lignin has high affinity to high-valence metal ions in soil, and lignin is used as a carrier of the fertilizer to adsorb or wrap the fertilizer, so that the purpose of slow release of the fertilizer can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special fertilizer for stress-resistant golf lawn grass and a preparation method thereof. Background technique [0002] At present, domestic golf lawn fertilizers are only conventional inorganic components and macromolecular humus organic fertilizers that have been passivated during production and processing. These organic fertilizers are basically slow fertilizers, and the humus contained in them needs to be decomposed by microorganisms for a long time before they can gradually become small molecular substances, making it difficult for most of the carbon to be absorbed by lawn grass. [0003] The ratio of inorganic compound fertilizers to organic and inorganic fertilizers in domestic golf lawn fertilizers is 9:1, obviously inorganic nitrogen, phosphorus and potassium compound fertilizers are mainly used, and the main content of these compound fertilizers is (c...

Problems solved by technology

These organic fertilizers are basically slow fertilizers, and the humus contained in them needs to be decomposed by microorganisms for a long time before they can gradually become small molecular substances, making it difficult for most of the carbon to be absorbed by lawn grass

[0003] The ratio of inorganic compound fertilizers to organic and inorganic fertilizers in domestic golf lawn fertilizers is 9:1, obviously inorganic nitrogen, phosphorus and potassium compound fertilizers are mainly used, and the main content of these compound fertilizers is (compound formula N-P2O5-K2O): 18-3 -18, 18-6-12, 18-2-10, 20-5-10 and other high-nitrogen compound fertilizers. The problems of this type of fertilizer are: 1. It is easy to cause soil compaction; 2. The fertilizer utilization rate is low, causing Waste of fertilizer and pollute the environment; 3. Under adverse environment, the root growth is weak, and the lawn absorbs nutrients efficiently; 4. The nutrient structure is single, lacking the supplement of carbon elements required by lawn grass, and the lawn has serious carbon starvation phenomenon

Conversely, long-term "carbon hunger" will lead to deteriorating microbial reproduction conditions, reduced soil fertility, and quick-acting nitrogen, phosphorus, and potassium fertilizers cannot be absorbed by crops. Instead, it will cause soil acidification, compaction, root system damage, and decline in lawn quality.

[0006] Turfgrass varieties for golf greens include Bermudagrass series, Seaside Paspalum series and Creeping Bentgrass series. Under low temperature conditions, the lawn’s resistance becomes weaker; under high temperature conditions, high temperature destroys the balance of photosynthesis and respiration of turfgrass , so that the lawn is in a state of starvation, and at the same time, the transpiration is strengthened, which destroys the water balance in the lawn grass; therefore, both low temperature and high temperature make the lawn's resistance worse, and even death will occur in severe cases
