Magnetic water-retaining fertilizer special for kiwi fruit and applied in autumn

Abstract

The invention discloses magnetic water-retaining fertilizer special for kiwi fruit and applied in autumn. The magnetic water-retaining fertilizer is prepared by, by weight, 25-28 parts of tobacco dregs, 55-60 parts of coconut coir, 22-25 parts of activated sludge, 0.6-0.7 part of copper sulfate powder, 1-3 parts of tamarind polysaccharide gum, 1-2 parts of ammonium molybdate, 3-5 parts of potassium nitrate, 0.2-0.3 part of potassium polyacrylate, 40-42 parts of fresh orange leaves, 0.3-0.5 part of zinc chloride, 0.6-0.7 part of ferric sulfate, 0.2-0.3 part of iron sulfate heptahydrate, 2-3 parts of 10% sodium dodecyl sulfate solution and an appropriate amount of water. The magnetic water-retaining fertilizer special for kiwi fruit and applied in autumn has the advantages that the nutrition deficiency problem which easily occurs in the flower bud differentiation period after the leaf falling of kiwi fruit plants in autumn is solved, the fermentation organic material components using the tobacco dregs and the coconut coir as the main raw materials are added in targeted manner, composite nutrition of the active sludge calcined materials is coordinated with the fermentation organic material components, the nutrition storage of the kiwi fruit trees after leaf falling is increased greatly, a nutrition foundation is provided for the growth of new buds and new shoots, and the growth environment of kiwi fruit is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special magnetic water-retaining fertilizer for autumn application 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 re...

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
