High-efficiency fertilizer suitable for sandy forest trees, and preparation method thereof

Abstract

The invention discloses a high-efficiency fertilizer suitable for sandy forest trees. The high-efficiency fertilizer comprises, by weight, 35-52 parts of fixing powder, 12-28 parts of a composite fertilizer, 20-35 parts of rape straws, 0.3-1 part of citric acid and 45-70 parts of distilled water. The invention also discloses a preparation method of the high-efficiency fertilizer suitable for sandyforest trees. The high-efficiency fertilizer suitable for sandy forest trees has a good fertilization effect, can provide sufficient nutrients for the growth of sandy forest tree seedlings, can effectively improve the fertilizing effect of the fertilizer on the sandy forest tree seedlings on the basis of fixing the fertilizer in sand grains through the co-action of the fixing powder and the rapestraws in order to improve the survival rate of the forest trees on the sandy land, and has a wide market prospect.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a high-efficiency fertilizer suitable for trees in sandy land and a preparation method thereof. Background technique [0002] In the usual sense, sandy land is expressed as land covered by sand and basically without vegetation. Sandy land is generally divided into sandy land, desert and desertified land. Among them, my country's deserts and desertified land are mainly distributed in the northwest region of the arid and semi-arid zone, Inner Mongolia and the west of the Northeast region. Due to factors such as long-term drought, these regions continue to erode the cultivated land area of ​​our country. There is a severe wind and sand attack, which has seriously affected people's survival and living environment. [0003] In order to slow down the land desertification in our country, sand trees are usually planted in deserts and desertified lands. Common sand trees include Populus euphrat...

AI Technical Summary

Problems solved by technology

However, these sandy land trees need a large amount of nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer for the rapid growth of tree stems and leaves in the early growth stage, and because the main component of desert and desertified land itself is sand grains, the internal fertilizer content is small, which cannot meet the needs of plants. Nutrient elements and water needed for the growth of seedlings. At the same time, there are many gaps between sand grains in deserts and desertified land, and the fertilizer and water contained in them will be exposed from the gaps, which is even more unfavorable for the growth of sandy trees.
