Growth-promoting slow release fertilizer special for lotus roots

Abstract

The invention discloses a growth-promoting slow release fertilizer special for lotus roots. The slow release fertilizer comprises fertilizer particles, slow release layers wrapping the surfaces of the fertilizer particles and protective layers wrapping the slow release layers; the fertilizer particles are prepared from urea, monoammonium phosphate, monopotassium phosphate, ground phosphate rock, potassium nitrate, potassium chloride, potassium minerals, magnesium humate, zinc humic acid, humic acid urea iron, boracic acid, copper citrate, manganese citrate, saccharomycetes, lactic acid bacteria, molasses, chitosan oligosaccharide, fresh ginger and 1-hydroxyethylidene-1,1-diphosphonic acid. According to the growth-promoting slow release fertilizer special for the lotus roots, the formula is reasonable, nutrition is balanced, and the growth of the lotus roots can be promoted; meanwhile, the slow release effect is achieved, onetime application can be conducted before transplantation, the utilization rate is high, and the obtained lotus roots are good in quality and high in yield.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special growth-promoting slow-release fertilizer for lotus roots. Background technique [0002] Lotus root, also known as lotus root, belongs to the rhizome of lotus, which can be used for food or medicine. It is planted in Jiangsu, Zhejiang, Hubei, Shandong, Henan, Hebei, Guangdong and other places in my country. Lotus root is rich in nutrition and delicious in taste. It can be eaten fresh or processed into lotus root powder, sugared lotus root slices, etc. It is a natural tonic and has become one of the necessary vegetables in people's daily life. [0003] The nutrients needed by lotus root during the growth and development process come from the photosynthesis of lotus leaves on the one hand, and from the soil on the other hand. However, the original fertilizer in the soil is limited, and it will become less and less as the plant grows and develops. top dressing. But t...

Problems solved by technology

However, the lotus root grows under the water, and it must be turned into the soil after topdressing. One is to be close to the root system after being put into the soil, which is easy to absorb, and the other is to prevent a large amount of nutrients from dissolving in the water, which will make the water eutrophic, which is not good for the growth of the lotus root.

However, it is difficult to turn the soil during the growth of lotus root, and the manual operation is time-consuming and laborious.

At present, there is still a lack of fertilizer varieties that have long fertilizer effects, nutrient release and meet the absorption requirements of lotus roots, and only need to be applied once before transplanting. As a result, during the process of planting lotus roots, the quality and yield of lotus roots are low, the growth is slow, and the benefits are not high.
