Embodiment 1
[0039] The impact of embodiment 1 ice fertilizer application on natural grassland forage grass output
[0040] Test location: degraded natural grassland in the second ranch of Xier Tala;
[0041] The test method is as follows:
[0042] 1. Reserve of cow urine
[0043] The manure storage tank of the second pasture of Xier Tala Farm, the manure is mainly wet liquid after dry-wet separation, mainly including cow urine, cleaning sewage and soluble matter in manure.
[0044] 2. Ice fertilizer formula
[0045] Prepared according to the mass ratio, cow urine feces: superphosphate: ammonium molybdate: boric acid = 1000kg: 1kg: 1g: 1g.
[0046] 3. Ice fertilizer production
[0047] Make ice fertilizer according to the above formula, and mechanically crush and granulate, the particle size is less than 3cm.
[0048] 4. Field application of ice fertilizer
[0049] Implementation time: November 20, 2016
[0050] Application method: Sprinkle directly on the surface of the grass with ...

Abstract
The invention relates to the technical field of natural grassland improvement, in particular to ice fertilizer made from cow urine, a preparation method thereof and a method for improving grassland. The ice fertilizer includes cow urine, superphosphate, ammonium molybdate and boric acid. The present invention combines the nutrient characteristics and chemical properties of cow urine, the climate characteristics of high-latitude cold regions, and the demand rules of plants for nutrients, and the invention uses cow urine to make ice fertilizer formula and the technical method of natural grassland improvement, which reduces the amount of cow urine. Pollution, rational use of its nutrient characteristics, improved nutrient recycling, improved grassland, improved grassland productivity, and hay yield increased by 50%‑100% compared with the control.
Description
technical field [0001] The invention relates to the technical field of natural grassland improvement, in particular to ice fertilizer made from cow urine, a preparation method thereof and a method for improving grassland. Background technique [0002] Each adult dairy cow excretes about 40-50 kg of fresh feces and 20 kg of cow urine per day. Adding sewage, the feces mainly composed of cow urine can reach nearly 30 kg, which is nearly 10,000 kg per year. Due to the acidic pH, natural exposure Leaked under natural conditions, the rich ammonia nitrogen volatilizes, causing pollution to the environment. Due to increasingly severe environmental protection problems and the requirements of sustainable agricultural development, how to utilize cow urine as a resource has become an urgent problem to be solved in pastoral areas. Cow urine is not only rich in nitrogen and potassium fertilizers, but also rich in medium-nutrient fertilizers such as copper and zinc. These are all necessar...
