Embodiment 1

[0029] Mix 20 parts of medical stone powder through a 60-mesh sieve, 20 parts of diatomite powder through a 60-mesh sieve, 5 parts of zeolite powder through a 60-mesh sieve, 25 parts of lime nitrogen, 5 parts of dicyandiamide and 25 parts of lignite , fully stirred, and after mixing uniformly, a disease prevention synergist was made; the nitrogen content of the disease prevention synergist in this embodiment was 8wt%.

[0030] Mix 13 parts of the above-mentioned disease prevention synergist with 37 parts of ordinary large granular urea, 25 parts of granular diammonium phosphate, and 25 parts of granular potassium sulfate, and stir evenly to prepare a special lawn fertilizer.

[0031] The present embodiment lawn special-purpose fertilizer nitrogen (N) 22wt%, phosphorus pentoxide (P 2 o 5 )12wt%, potassium oxide (KO 2 ) 12.5wt%, and the total nutrient content of nitrogen, phosphorus and potassium is 46.5wt%.

Embodiment 2～10

[0033] The difference from Example 1 is that the ratio of raw materials is different (see Table 1), and the preparation method is the same as in Example 1. The preparation process of each group of special fertilizers is to prepare the disease prevention synergist first, and then the disease prevention synergist Added to granular chemical fertilizers to make long-lasting lawn fertilizers for disease prevention.

Abstract

The invention relates to soil fertilizer and plant disease and insect pest control technology, in particular to a special disease-resistant and long-acting fertilizer of lawn and a preparation method thereof, solving the problem of lawn disease and insect pest control and fertilizer decrement application. The special disease-resistant and long-acting fertilizer for lawn comprises the following components in parts by weight: 10-15 parts of disease-resistant synergist, 30-40 parts of nitrogenous fertilizer, 20-30 parts of phosphatic fertilizer and 20-30 parts of potash fertilizer, wherein the disease-resistant synergist comprises the following components in parts by weight: 15-20 parts of medical stone powder, 15-20 parts of kieselguhr powder, 5-10 parts of zeolite, 20-30 parts of lime nitrogen, 5-10 parts of dicyandiamide and 20-30 parts of lignite. The preparation method of the special fertilizer comprises: medical stone powder, kieselguhr powder, zeolite, lime nitrogen, dicyandiamideand lignite are mixed and evenly stirred to prepare the disease-resistant synergist; and then the disease-resistant synergist, particle nitrogen, phosphorus and potash fertilizer are mixed and evenlystirred to prepare the special fertilizer. The preparation method of the invention is simple, has no pollution, can obviously improve fertilizer utilization ratio, prevents and cures diseases and prolongs lawn green period.

Description

technical field [0001] The invention relates to soil fertilizer and plant disease and insect pest control technology, in particular to a special fertilizer for disease prevention and long-acting lawn and a preparation method thereof. Background technique [0002] With the continuous expansion of the area of ​​green lawns, the role of lawn management and maintenance has become increasingly prominent. Due to the immaturity of lawn management and maintenance technology in our country, domestic lawns generally degrade and fall into disrepair within 5 to 7 years, and some lawns even become deserted after they are bred. The lawn with relatively perfect management and maintenance technology in developed countries can be used for more than 10 to 15 years. "Three minutes of planting, seven minutes of cultivation", the management and maintenance of green lawns are necessary technologies for the development of green lawns. [0003] Fertilization is an important part of lawn managemen...
