Magnetic water-retaining fertilizer for preventing root burning of kiwi fruits

Abstract

The invention discloses a magnetic water-retaining fertilizer for preventing root burning of kiwi fruits. The magnetic water-retaining fertilizer is prepared from the following raw materials in parts by weight: 55-60 parts of rape seed cakes, 34-38 parts of sunflower seed husk, 15-17 parts of phosphogypsum, 0.6-0.8 part of magnesium sulfate, 1.2-1.5 parts of hydroxypropylmethyl cellose, 2-3 parts of calcium nitrate, 4-5 parts of ammonium dihydrogen phosphate, 0.2-0.4 part of potassium polyacrylate, 44-46 parts of fresh tangerine leaves, 0.2-0.3 part of zinc chloride, 1.0-1.2 parts of ferric sulfate, 0.5-0.6 part of ferrous sulfate heptahydrate, 3-4 parts of 10% sodium dodecyl sulfate solution and a proper amount of water. According to the fertilizer disclosed by the invention, the growth needs of the kiwi fruits can be met, the overnutrition condition is avoided, and compared with the traditional fertilizer needing to be used at a position away from the root system, the magnetic water-retaining fertilizer disclosed by the invention has the advantages that the fertilization method can be optimized, and the condition that the plant growth is influenced by root burning is avoided.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a magnetic water-retaining fertilizer for preventing root burning of 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 requi...

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
