TABLE 1 Effect of ice foiling machine application technique on Natural grassland Biomass
The reason why the ice manure and the application technology improve the forage grass yield is analyzed. The fertilizer effect of the ice fertilizer mainly comprises the following points:
(1) the cow urine contains rich ammonia nitrogen and potassium fertilizers, and the proportion of nitrogen, phosphorus and potassium fertilizers is supplemented by increasing the content of phosphate fertilizers.
(2) The cow urine contains rich copper-zinc fertilizer, and the zinc fertilizer can improve the drought resistance and low-temperature resistance of crops and promote healthy growth of branches and leaves; and is involved in the synthesis of chlorophyll and auxin. Copper is a component of a plurality of oxidases in plants, particularly a main component of superoxide dismutase, participates in the oxidation-reduction reaction in plants, promotes the stabilization of phytoalexin and other pigments, and promotes the stress tolerance of plants.
(3) Molybdenum is a component of nitrate reductase, participates in the reduction of nitrate and nitrogen metabolism in plants, and is also a main component of nitrogen fixation enzyme, and the molybdenum fertilizer increases and promotes the nitrogen fixation capability of leguminous plants.
(4) The boric fertilizer can promote the growth of plant roots and the absorption of phosphate fertilizer, and simultaneously can improve the stress resistance and disease resistance of plants.
(5) The ice fertilizer contains more sodium, and the increased calcium in the calcium superphosphate can antagonize the ionic effect of the sodium.
(6) The added calcium superphosphate and boric acid are both acidic substances, the pH value of the urine can be adjusted, the pH value of the original urine is acidic at 8.0-8.5, and the pH value of the adjusted ice fertilizer is neutral.
The reason why the yield of the forage grass is improved by applying the ice fertilizer in winter. The conventional cow urine and the like are mostly used as environmental pollutants and are difficult to treat. The natural grassland applied in winter has the following advantages by the preparation of the ice fertilizer:
(1) after the ice fertilizer is prepared, the natural grassland is applied in winter, the volatilization of ammonia nitrogen and the like is reduced, and the accumulated snow in winter also plays a role in covering the ice fertilizer.
(2) The ice fertilizer is applied to the grassland, the freezing and thawing are performed alternately in spring, the nutrients of the ice fertilizer are gradually diluted along with the melting of snow water and uniformly permeate into a soil layer, and the absorption and utilization of the plants on the nutrients are ensured.
(3) Along with the green turning of the grassland, the ice fertilizer is melted and dispersed to the soil and around the root system, thereby providing nutrients for the rapid growth of plants and ensuring the yield of the forage grass in the whole growing season.
The ice fertilizer and the natural grassland utilization technology solve the problem that cow urine as a pollutant is difficult to treat, and meanwhile, the productivity of the natural grassland is improved by recycling nutrients, so that sufficient forage grass is provided for the development of animal husbandry.
Compared with the mode that the cow urine is directly applied to the grassland in summer, the biomass is reduced in 2017 and 2018, which shows that the grass yield is reduced when the cow urine is directly applied in summer. The main reasons are the following disadvantages:
(1) the high content of sodium ions in the cow urine causes salt damage, which is not beneficial to the normal and rapid growth of plants.
(2) The high pH of cow urine causes alkali damage to grasslands, which is not favorable for the normal and rapid growth of plants.
(3) When the nutrient solution is applied in summer, nutrients in the cow urine cannot rapidly enter underground soil on the ground surface, and the nutrients are lost in the form of ammonia gas and the like.
(4) The cow urine contains some bacteria and microorganisms which are not beneficial to plant growth, and the like, and causes certain pollution to the environment.
The cattle urine is directly used for ice fertilization (comparative example 3), and the forage grass yield in 2017 and 2018 is improved to a certain extent. The main reasons include:
(1) nutrients such as nitrogen and phosphorus fertilizers contained in the urine of the cattle can be absorbed and utilized by plants, the salt alkalinity harm caused by fertilization in summer is caused in a relative link of the application mode of the ice fertilizer, and the ice fertilizer is applied in a slow release effect.
(2) Although the saline-alkali property of the cow urine is relieved to some extent, the effect on the growth of plants is still influenced to some extent in a long-term mode.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
