Abstract

The invention discloses a eucalyptus high-efficiency foliar fertilizer and a preparation method thereof, and belongs to the technical field of agriculture and forestry fertilizers. The foliar fertilizer is prepared from the following raw materials, by mass: 20-25 parts of potassium dihydrogen phosphate, 35-45 parts of potassium nitrate, 50-60 parts of ammonium nitrate, 7-9 parts of sodium octaborate tetrahydrate, 8-12 parts of EDTA iron, 2-4 parts of EDTA manganese, 4-6 parts of EDTA zinc, 1-2 parts of EDTA copper, 0.8-1.5 parts of ammonium molybdate, 2-3 parts of nano SiO2, 300-400 parts of polyglutamic acid fermentation liquor and 480-550 parts of biocontrol bacteria. The eucalyptus foliar fertilizer is prepared according to the steps of dissolving, emulsifying and the like so as to solve the technical problems that the growth of eucalyptus is influenced due to untimely nutrition supply and the environment is influenced due to unreasonable foliar fertilizer formula, and the reasonable formula is combined with regular scientific spraying, so that the fertilization cost can be greatly reduced, the labor cost is reduced, and good economic benefits and social benefits are obtained.

Description

technical field [0001] The invention relates to a high-efficiency foliage 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 species in tropical and subtropical regions, eucalyptus has the advantages of fast growth and high economic benefits, and is widely planted in southern my country. A growth cycle of eucalyptus needs to absorb more nutrients. Due to the high labor cost at present, the fertilization of eucalyptus is generally done once a year in March-April. During the whole growth cycle, it is easy to cause deficiency disease due to untimely nutrient supply, which affects the eucalyptus. growth rate. [0003] At present, there are no mature eucalyptus-specific foliar fertilizer products in the market. It is an urgent task to realize the sustainable development of eucalyptus plantations, which is also i...
