Fertilizer for poplars

Abstract

The invention relates to the field of fertilizers and particularly relates to a fertilizer for poplars. The fertilizer is prepared from the following ingredients in parts by weight: 20-25 parts of straws, 10-20 parts of sawdust, 10-12 parts of expansible perlite powder, 1-2 parts of nitrification inhibitor DMPP, 0.3-0.5 part of tea saponin, 20-40 parts of seabird dung, 10-20 parts of silkworm feces, 5-15 parts of animal bone meal, 5-15 parts of sorghum stalk powder, 15-25 parts of bean dregs, 10-20 parts of cottonseed meal, 5-15 parts of grain stillage, 10-20 parts of vinegar residues, 10-20 parts of traditional Chinese medicine decoction dregs, 10-20 parts of castor roots, 5-15 parts of Sophora japonica leaves, 10-20 parts of peach leaves, 20-30 parts of pine needles, 20-30 parts of Chinaberry barks, 10-20 parts of Achnatherum inebrians, 20-30 parts of urea, 10-20 parts of calcium nitrate, 20-30 parts of magnesium chloride, 5-15 parts of magnesium acetate and 5-15 parts of zinc sulfate. The fertilizer disclosed by the invention can be used for improving the quality of the poplars, and meanwhile, can also be used for improving the structure of soil, avoiding soil hardening caused by excessive chemical fertilizer use, increasing organic matters of the soil and maintaining the ecological balance of the soil.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a poplar fertilizer. Background technique [0002] In order to live normally, poplar must absorb various nutrients from the soil. Most poplar forests in my country have low fertility and less organic matter in the soil, usually less than 0.5% to 1%; the content of nitrogen, phosphorus and potassium is at a low level. In many afforestation lands in the north, the soil contains more sand, less clay, less silt, low fertility, and the groundwater level is often lower than 3 meters, and seasonal water supply is insufficient. actual [0003] There is a considerable gap between the site conditions of most poplar forests in my country and the suitable conditions for poplar trees, and the lack of fertility restricts the growth of poplar trees. [0004] In addition, continuous poplar cropping is very common in plain agricultural areas with a lot of people and little land, and the poplar rotat...
