Aspen fertilizer

Abstract

The invention discloses aspen fertilizer which comprises the following raw materials, 20-40 parts of guano, 10-20 silkworm excrement, 5-15 parts of animal bone powder, 5-15 parts of broomcorn straw powder, 30-40 parts of wood processing saw dust, 15-25 parts of bean pulp, 10-20 parts of cottonseed meal, 5-15 parts of grain stillage, 10-20 parts of vinegar residue, 10-20 parts of traditional Chinese medicine dregs, 10-20 parts of castor roots, 5-15 parts of pagoda leaves, 10-20 parts of peach leaves, 20-30 parts of pine needles, 20-30 parts of cortex meliae, 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 aspen fertilizer can improve the quality of aspens, an can improve soil structure at the same time, soil hardening due to that fact that chemical fertilizer is applied too much is avoided, organic materials of the soil are increased, and soil ecological balance is maintained. The added traditional Chinese medicine can expel, kill and prevent pests, pesticide consumption is reduced or avoided, the disease-resistant, pest-resistant and lodging-resistant capacity of the aspens is improved, and the aspen fertilizer has good economical and environmental benefits.

Description

technical field [0001] The invention relates to a plant fertilizer, 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, and low fertility. Moreover, the groundwater level is often lower than 3 meters, and seasonal water supply is insufficient. In fact, 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. [0003] In addition, continuous cropping of poplars is very common in plain agricultural areas with a lot of people and little land, and the poplar rotat...
