Eucalyptus tending and top dressing and its fertilizing method

Abstract

The invention discloses topdressing for fostering eucalyptus. The topdressing is used for fertilizing eucalyptus plantation, and is prepared from raw materials of macroelements of nitrogen, phosphorus and potassium, and microelements of calcium, magnesium, silicon, boron, zinc, copper and molybdenum by the processes of crushing, mixing, pelletizing and the like; the topdressing for fostering eucalyptus comprises the following effective components by weight percent: 18-32% of nitrogen, 3-12% of phosphorus pentoxide, 8-22% of potassium oxide, 5-12% of calcium oxide, 1-5% of magnesium oxide, 2-5% of silica, 0.01-1% of boron, 0.01-1% of zinc, 0.01-1% of copper, and 0.001-0.1% of molybdenum. Correspondingly, the invention also discloses a fertilizing method of the topdressing for fostering eucalyptus. By adopting the topdressing, kinds of necessary nutrients for eucalyptus growth can be met, the fast-growing advantages are fully developed, unnecessary waste of fertilizer nutrients can be reduced, the disease resistance, the wind resistance and the cold resistance of the eucalyptus can be enhanced, and scientific fertilization can be achieved.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a eucalyptus tending top dressing and a fertilization method thereof. Background technique [0002] Eucalyptus has excellent characteristics such as fast growth, high yield, and multiple uses. It has been planted on a large scale in the production of tropical and subtropical short-rotation plantations in my country. In order to obtain a higher growth in a short period of time, it must be fertilized reasonably, especially in the barren south. The effect of fertilization in soil afforestation is very obvious, and fertilization is an important measure to build a high-yield eucalyptus forest. [0003] In the first rotation period of eucalyptus high growth, reasonable fertilizer is the primary material guarantee. In areas where no special fertilizer for eucalyptus is known, most growers will use three imported compound fertilizers of 16 (N:P:K=16:16:16) or three domestic compound fertilizer...

AI Technical Summary

Problems solved by technology

And use this kind of fertilizer as base fertilizer or topdressing, because the demand of eucalyptus to nitrogen, phosphorus and potassium is different from that of crops, this not only causes the waste of fertilizer nutrient, increases the cost, but also lacks the medium and trace elements (calcium and magnesium) necessary for the growth of eucalyptus Boron and zinc) cause eucalyptus to fail to grow normally and reduce disease resistance, which is also the reason why eucalyptus in some places cannot guarantee high survival rate and slow growth due to bacterial wilt
