High-quality special fertilizer for purple sweet potatoes

Abstract

The invention discloses a high-quality special fertilizer for purple sweet potatoes. The high-quality special fertilizer is prepared from the following substances in parts by weight: 20 to 25 parts of urea, 15 to 20 parts of potassium humate, 4 to 6 parts of magnesium sulfate, 3 to 5 parts of boracic acid, 2 to 4 parts of zinc ligninsulfonate, 2 to 5 parts of diaminoferric xanthohumate, 1 to 3 parts of manganese amino acid chelate, 30 to 50 parts of modified purple sweet potato straws and 0.5 to 1 part of prohexadione calcium. According to the high-quality special fertilizer, the purple sweet potato straws are used as organic components, nutritional components conform to the growth rule of the purple sweet potatoes, through special modified treatment, the fermentation time is shortened, the utilization rate of raw materials is increased, more small molecular substances which are easy to absorb are decomposed, the effect of enhancing the stress resistance of plants is achieved, and inorganic fertilizers are applied, so that the yield and quality of the purple sweet potatoes are greatly increased, and additionally, the soil environment is improved.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a high-quality special fertilizer for purple sweet potatoes. Background technique [0002] Purple sweet potato has attracted much attention because it is rich in anthocyanins and other health-care substances for human nutrition. It can be eaten fresh, extracted from pigments, processed into whole powder, and processed as snack food. The market demand is strong and the planting efficiency is high. At present, people have applied a large amount of common inorganic fertilizers in order to obtain higher yields. Their utilization rate is low, and long-term use will cause soil compaction and soil quality degradation. When planting purple sweet potatoes, the stems and leaves need to be managed, and letting the stems and leaves grow will also reduce the yield. Usually, the purple sweet potato vines will be directly burned after harvesting. With the strengthening of people's awareness of enviro...

Problems solved by technology

At present, in order to obtain higher yields, people have applied a large amount of common inorganic fertilizers. Their utilization rate is low, and long-term use will cause soil compaction and soil quality degradation.

When planting purple sweet potatoes, the stems and leaves need to be managed, and letting the stems and leaves grow will also reduce the yield. Usually, the purple sweet potato vines will be directly burned after harvesting. With the strengthening of people's awareness of environmental protection, incineration will no longer be used Instead, it is fermented in the open air or buried in the soil as an organic fertilizer. However, due to the existing technology, the processing time is too long and the use effect is low, which reduces people's enthusiasm for reuse.
