Special full-element functional fertilizer for eucalyptus and preparation method thereof

Abstract

The invention discloses a special full-element functional fertilizer for eucalyptus and a preparation method thereof. The fertilizer is prepared from the following components in parts by mass: 120-160parts of urea, 162-192 parts of ammonium sulfate, 105-145 parts of potassium chloride, 90-100 parts of calcium magnesium phosphate fertilizer, 52-68 parts of monoammonium phosphate, 25-35 parts of ammonium nitrate, 3.5-5 parts of boric acid, 4-5 parts of ferrous sulfate heptahydrate, 1-2 parts of manganese sulfate monohydrate, 1-2 parts of manganese sulfate heptahydrate, 2.5-4 parts of zinc sulfate heptahydrate, 1-2 parts of copper sulfate pentahydrate, 0.5-0.8 part of ammonium molybdate, 5-8 parts of polyglutamic acid fermentation product, 300-330 parts of 60% organic matter decomposed product, 28-35 parts of alcohol fermentation concentrated solution and 5-6 parts of composite functional bacteria. The fertilizer is prepared from the steps of crushing, stirring and granulating. By meansof the fertilizer, soil fertility can be continuously improved, continuous cropping obstacles are relieved, the eucalyptus growth rate is increased, and the effects of adjusting soil and relieving andpreventing diseases are comprehensively achieved.

Description

technical field [0001] The invention relates to a special whole element functional fertilizer for eucalyptus and a preparation method thereof, belonging to the technical field of agricultural and forestry fertilizers. Background technique [0002] As one of the most important fast-growing afforestation tree species in tropical and subtropical regions, eucalyptus has the advantages of large growth and high economic benefits, and is widely planted in southern my country. A growth cycle of eucalyptus needs to absorb more nutrients. After ordinary inorganic fertilizers are applied, part of them will be transpired, dissipated and lost with water, and only part of the nutrients will be absorbed and utilized by plants. The utilization rate of ordinary inorganic fertilizers is very low. According to research, the utilization rate of eucalyptus to urea and ammonium bicarbonate in ordinary inorganic fertilizers reaches 20-46%, phosphate fertilizers (diammonium, monoammonium, heavy cal...

AI Technical Summary

Problems solved by technology

The utilization rate of ordinary inorganic fertilizers is very low. According to research, the utilization rate of eucalyptus to urea and ammonium bicarbonate in ordinary inorganic fertilizers reaches 20-46%, phosphate fertilizers (diammonium, monoammonium, heavy calcium) reach 10-25%, and potassium fertilizers reach 45%. -60%. According to the short-board theory of wooden barrels, if there is a lack of other nutrients, the eucalyptus will not grow normally, which will seriously affect the yield.

Moreover, if a large amount of inorganic fertilizers are applied for a long time, the utilization rate of fertilizers will decrease year by year, increasing the dependence of eucalyptus on inorganic fertilizers, which will easily cause fertilizer loss, pollute groundwater sources, soil acidification and hardening, and soil-borne diseases are difficult to control. The sustainable development of forest land is worrying.

Most of the currently commercially available eucalyptus fertilizers are mainly composed of N, P, and K inorganic elements. The organic and inorganic eucalyptus fertilizers also overemphasize the content of N, P, and K, ignoring the utilization rate of fertilizers and the comprehensive results obtained by fertilization. Benefits, excessive application of multi-element inorganic fertilizers may have a relatively large negative effect on the soil structure and the ecological environment, which is not in line with the industrial policy of weight loss and efficiency enhancement advocated by the state
