Problems solved by technology

There is no significant difference between the above-mentioned fertilizer formula and use for artificial grassland or turf and the planting industry. Since most of the vegetation on artificial grassland or turf is a single species, it basically does not involve biodiversity protection and ecosystem functions.
Therefore, related technologies cannot be directly applied to natural grass

Embodiment 1

[0025] In this embodiment, the formula fertilizer raw material composition includes: 29.55wt% of ordinary urea, 11.65wt% of ammonium dihydrogen phosphate, 24wt% of potassium sulfate, 2.25wt% of zinc sulfate heptahydrate, 3.6wt% of sodium tetraborate decahydrate, dicyandi Amine 0.12wt%, lignite 28.83wt%.

[0026] The above-mentioned raw materials are added into the mixing machine according to the weight percentage, mixed evenly, and then packaged to obtain the finished product.

[0027] The nutrient content of this embodiment formula fertilizer is by weight percentage, and nitrogen accounts for 15wt%, and phosphorus pentoxide accounts for 7wt%, and potassium oxide accounts for 12wt%, and boron accounts for 0.4wt%, and zinc accounts for 0.5wt%, and sulfur accounts for 4.7wt%. Cyanamide 0.12wt%; wherein the total content of nitrogen, phosphorus and potassium is 34wt%.

Embodiment 2－10

[0029] The difference from Example 1 is that: the ratio of raw materials is different (Table 1), the specific implementation method is the same as Example 1, and the weight percentage of the main nutrient content of the formula fertilizer in each example is shown in Table 2.

Abstract

The invention relates to soil fertilizer technology, specifically to a special formula fertilizer for northern mowing grasslands and a use method of the special formula fertilizer. The fertilizer comprises the following materials by weight: 27.8 to 31.3 percent of urea, 10.0 to 13.3 percent of ammonium dihydrogen phosphate, 20.0 to 28.0 percent of potassium sulphate, 1.8 to 2.7 percent of heptahydrate, 2.7 to 4.5 percent of sodium tetraborate decahydrate, 0.1 to 0.15 percent of dicyanodiamine, and 20.05 to 37.6 percent of accessories lignite. According to the invention, the use method of the special formula fertilizer is suitable for natural mowing grasslands which ban grazing through fencing in North China; the best fertilizing time is in late May or early June; and the dosage of each hectare is 75 to 225kg. The special formula fertilizer is suitable for the northern mowing grasslands to balance the nutrient contents, improve the productivity of the grasslands, and maintain the ecosystem function of the grasslands and the biodiversity.

Description

technical field [0001] The invention relates to soil fertilizer technology, in particular to a special formula fertilizer for mowing grassland in northern China and its application method. Background technique [0002] Since the implementation of the fence and grazing prohibition policy in my country, mowing has become the most important grassland utilization method in the north. In grassland systems with relatively good climatic conditions and relatively high vegetation productivity, appropriate frequency and intensity of mowing can stimulate compensatory or even supercompensatory growth of plants, thereby obtaining higher plant productivity. In recent years, foreign researchers have studied the effects of mowing period, mowing frequency, and mowing interval on grassland community composition, productivity, and grass quality, and found that mowing can significantly improve the quality of pasture, which is beneficial to animal utilization. However, if the frequency and inte...
