Problems solved by technology

[0004] In nursery production and greening management, pruning is essential to maintain the beautiful branches of willow trees. The number of branches produced by pruning is huge, and greening branches have always been regarded as solid waste, while traditional landfill and incineration disposal methods , which not only increases the pressure of garbage disposal, but also causes environmental pollution, which no longer meets the requirements of environmental protection and sustainable development.

Embodiment 1

[0030] Such as figure 1 Shown is a kind of slow-release organic fertilizer preparation method that takes branch as main raw material, and concrete steps are.

[0031] (1) Branch crushing: Collect tree branches and crush them through a branch crusher to fully and effectively crush them to increase the contact area to facilitate full contact fermentation.

[0032] (2) Mixing of materials: according to volume percentage, wet 55-75% of the crushed branches with water, add 25% chicken manure, add 2% calcium phosphate, 1% ferrous sulfate and 1.5‰ fiber Decompose bacteria, mix and stir, accumulate layer by layer, and be sure. (Materials must be mixed evenly before stacking. When mixing, coarse texture materials should be spread on the bottom first, and fine texture materials should be spread on the top. When there is a large amount, you can use a shovel to turn it, and when it is small, use a flat shovel to turn it until Until it is uniform, it can be sealed with a plastic film to ...

Embodiment 2

[0043] Such as figure 1 Shown is a kind of slow-release organic fertilizer preparation method that takes branch as main raw material, and concrete steps are.

[0044] (1) Branch crushing: Collect tree branches and crush them through a branch crusher to fully and effectively crush them to increase the contact area to facilitate full contact fermentation.

[0045] (2) Material mixing: according to the volume percentage, wet 75% of the crushed branches with water, add 45% cow dung, add 5% calcium phosphate, 3% ferrous sulfate and 3‰ cellulolytic bacteria , mixed and stirred, piled up layer by layer, practical. The materials must be mixed evenly before they are piled up. When mixing, the coarse texture materials should be spread on the bottom first, and the fine texture materials should be spread on the top. When the amount is large, you can use a shovel to turn it over, and when it is small, use a flat shovel to turn it until it is even. So far, it is enough to seal it with pla...

Abstract

The invention discloses a sustained-release organic fertilizer taking tree branches as a main raw material. The sustained-release organic fertilizer is composed of, by volume, 55 to 75% of smashed tree branch, 25 to 45% of animal manure, 2 to 5% of phosphate fertilizer, 1 to 3% of iron fertilizer, and 0.15 to 0.3% of cellulose-decomposing bacteria. A preparation method of the sustained-release organic fertilizer comprises following steps: branch smashing; material blending; fertilizer heap volume controlling; heap turning; and maturity judgement. Raw material source is wide; the raw materials are free, and are easily available; the obtained sustained-release organic fertilizer is abundant in nutrients, is air permeable, possesses water absorption, is green and friendly to the environment, and is a best culturing soil. Application of the sustained-release organic fertilizer is capable of activating soil nutrients, improving soil texture, promoting absorption of plants on nutrients, reducing plant diseases and insect pests, and reducing pesticide residue.

Description

technical field [0001] The invention relates to a method for preparing an organic fertilizer, in particular to a method for preparing a slow-release organic fertilizer with branches as main raw materials. Background technique [0002] The branches of trees have the function of transporting nutrients and water and supporting the growth of leaves, flowers and fruits in a certain space. Willow, also known as willow, is a deciduous tree belonging to Salicaceae Salicaceae, with a height of up to 20m and a diameter at breast height of 0.8m. The willow branches are slender, soft and drooping, and they are highly resistant to drought and water. They are widely distributed in northeast, north, northwest and Yangtze River River basins, the Yellow River basin is the main distribution center; willows have plump canopies, grow rapidly, and leave early and fall late. They are commonly used as shade trees and street trees in northern China, and are also often used as road trees, shelter fo...
