Magnetic water retention fertilizer for producing selenium-rich kiwi fruit

Abstract

The invention discloses a magnetic water retention fertilizer for producing selenium-rich kiwi fruit. The magnetic water retention fertilizer is prepared from the following raw materials by weight: 2-4 parts of selenium yeast, 58-60 parts of dry rabbit dung powder, 33-35 parts of tea bran, 20-22 parts of degranulated cob, 1-2 parts of borax, 0.8-1.2 parts of sodium silicate, 3-4 parts of sodium humate, 1-2 parts of potassium carbonate, 0.2-0.3 part of potassium selenite, 0.1-0.2 part of potassium polyacrylate, 40-44 parts of fresh tangerine leaf, 0.3-0.4 part of zinc chloride, 0.8-1.0 part of ferric sulfate, 0.4-0.5 part of ferrous sulfate, 2-4 parts of sodium dodecyl sulfate of 10%, and proper amount of water; the magnetic water retention fertilizer takes the selenium yeast and the potassium selenite as selenium sources, organic selenium and inorganic selenium are added in the fertilizer in the two modes, the release of the selenium is prolonged through the coating of a calcined powdered carbon of the cob, sodium silicate and the like, the selenium is complexed and adsorbed through the higher loading capacity of the sodium humate, so that the long-term effective selenium intake of a root system of a kiwi fruit plant is realized, and an excellent technical support is provided for the production of the selenium-rich kiwi fruit.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a magnetic water-retaining fertilizer for producing selenium-enriched kiwifruit. Background technique [0002] Kiwi fruit is soft in texture and has a sweet and sour taste. It contains organic substances such as actinine, proteolytic enzymes, tannin pectin and sugars, as well as trace elements such as calcium, potassium, selenium, zinc and germanium, and 17 kinds of amino acids needed by the human body. Fruits with fresh quality, rich nutrition and delicious flavor play an important role in maintaining human health. Kiwifruit is a berry-like vine fruit tree with fleshy roots, vigorous growth, luxuriant branches and leaves, many and early results, and consumes a large amount of nutrients every year, and the available nutrients in the soil are difficult to meet its needs. Therefore, it is necessary to accurately grasp its fertilizer requirements. Timely supplementation of requ...

Problems solved by technology

At present, kiwifruit fertilization is mainly based on quick-acting fertilizers. Although the yield of kiwifruit has been greatly increased, the nutrient utilization rate of quick-acting fertilizers is low, which is easy to cause soil compaction, eutrophication of surface water and pollution of groundwater, which will also lead to deterioration of kiwifruit fruit quality. A sharp decline
