Abstract

A slow-release organic fertilizer for plantation of kiwi is prepared from the following raw materials, by weight, 8-10 parts of perlite, 10-12 parts of rotten fruit and vegetable, 8-9 parts of chicken manure, 14-16 parts of attapulgite, 3-4 parts of EM biological strain, 2-3 parts of agar powder, 6-8 parts of dry pond sludge, 4-5 parts of magnesium sulfate, 4-6 parts of potassium permanganate, 3-5 parts of iron chloride, 6-8 parts of sodium humate, 8-10 parts of ammonium bicarbonate, 4-5 parts of an auxiliary agent and a proper amount of water. The organic fertilizer provided by the invention is a specially-designed fertilizer for plantation of kiwi. By compounding of perlite, the organic fertilizer with an adsorption function is prepared. The fertilizer is firstly ground to a sand shape and then is coated with a layer of agar membrane. Then, elements can effectively be absorbed, use of the fertilizer is minimized and soil hardening is prevented. By addition of magnesium sulfate, potassium permanganate, iron chloride, sodium humate and the like, contents of magnesium, potassium, iron and the like are supplemented for the fertilizer. By addition of acid, soil acidity can be improved. By the use of the organic fertilizer, abuse of fertilizer is minimized, and consumption of energy is also reduced.

Description

technical field [0001] The invention relates to a slow-release organic fertilizer for kiwifruit planting and a preparation method thereof, belonging to the technical field of organic fertilizer in fertilizer. Background technique [0002] Kiwifruit likes sandy soil with deep upper layer, fertile and loose, good water retention and drainage, and high humus content. It does not have strict requirements on soil pH, but plants grow well on acidic or slightly acidic soil, and the suitable pH range is 5.5 to 6.5. It can also grow on neutral (pH7.0) or slightly alkaline (pH7.8) soil, but the yellowing phenomenon often occurs in the seedling stage, and the growth is relatively slow. In addition to soil quality and pH, the mineral nutrients in the soil also have an important impact on the growth and development of kiwifruit. In addition to nitrogen, phosphorus, and potassium, kiwifruit also needs rich magnesium, manganese, zinc, iron and other elements. If these mineral elements ar...
