Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0022] The invention provides a technical scheme: a topdressing type eucalyptus fertilizer, comprising the following active ingredients in weight percentage:

[0023] Calcium 0.2-0.3%;

[0024] Magnesium 0.11-0.19%;

[0025] Phosphorus 7-10%;

[0026] Boron 0.04-0.07%;

[0027] Zinc 0.07-0.11%;

[0028] Nitrogen 7-10%;

[0029] Potassium 7-10%;

[0030] Lime 20-65%;

[0031] Humus 20-40%.

[0032] In this embodiment, the magnesium source is at least one of magnesium sulfate, magnesium nitrate and magnesium chloride, the calcium source is granular superphosphate, and the phosphorus source is monoammonium phosphate, diammonium phosphate, calcium hydrogen phosphate, At least one of superphosphate, the potassium source is at least one of potas...

Abstract

The invention relates to the technical field of eucalyptus fertilizers, and discloses a topdressing type eucalyptus fertilizer, which comprises the following active ingredients by weight: 0.2-0.3% of calcium; 0.11 to 0.19% of magnesium; 7-10% of phosphorus; 0.04 to 0.07 percent of boron; 0.07% to 0.11% of zinc; 7-10% of nitrogen; 7-10% of potassium; and 20-65% of lime. The elements contained in the fertilizer can improve the nutrient utilization rate, nutrients are reasonable and balanced, negative effects on the environment are reduced, rapid and robust growth of eucalyptus is promoted, short-period cultivation of eucalyptus is achieved, the production cost is low, and economic benefits are effectively improved.

Description

technical field [0001] The invention relates to the technical field of eucalyptus fertilizer, in particular to a topdressing type eucalyptus fertilizer. Background technique [0002] Eucalyptus is the general term for species of Eucalyptus in the family Myrtaceae, and together with poplar and pine, it is called the world's three largest fast-growing tree species. Because eucalyptus grows rapidly, it absorbs a lot of nitrogen, phosphorus, potassium, sulfur, calcium, magnesium and trace elements from the soil, but these nutrients are limited in the soil. In order to ensure the normal growth of eucalyptus and maintain the balance between supply and demand of nutrients, some fertilizer factories have produced special compound fertilizers for eucalyptus. Compared with single element urea, phosphorus fertilizer and potassium fertilizer, the compound fertilizer has more complete nutrition and has stronger scientific rationality. [0003] Existing special compound fertilizers for e...
