Insect pest preventing efficient slow release fertilizer for Chinese cabbages

Abstract

The invention discloses an insect pest preventing efficient slow release fertilizer for Chinese cabbages. The insect pest preventing efficient slow release fertilizer is prepared from the following raw materials: thoroughly decomposed pig manure, fermented bean dregs, composite urea, diammonium phosphate, a calcium-magnesium phosphate fertilizer, rock flour, pine needle mulch, borax, talcum powder, shell powder, a microbial agent, citric acid, tartaric acid, seaweed meal, radix glycyrrhizae, wood vinegar, a folium meliae azedarach extracting solution, a pyrethrum extracting solution, and an envelope agent. The insect pest preventing efficient slow release fertilizer for Chinese cabbages disclosed by the invention is reasonable in formula, is high in fertilizer utilization rate, is good inslow release effect, does not need to top dressing after once fertilizer application, further can improve the quality of Chinese cabbages while increasing the yield of the Chinese cabbages, is small in environmental harm after being applied, and can effectively improve physical and mechanical properties of soil.

Description

technical field [0001] The invention relates to the technical field of agricultural chemical fertilizers, in particular to an insect-resistant high-efficiency slow-release fertilizer for cabbage. Background technique [0002] Cabbage is rich in a variety of nutrients. Regular consumption has the effects of nourishing the stomach and promoting body fluid, eliminating restlessness and quenching thirst, diuresis and laxative, clearing away heat and detoxification, and is deeply loved by consumers. With the promotion and use of fertilizers and greenhouses, the output of Chinese cabbage has increased year by year, effectively meeting people's daily needs. [0003] Because cabbage has the characteristics of long growth period and large nutrient demand, it is generally difficult to meet its growth demand under the condition of one-time application of conventional fertilizers. Therefore, in order to achieve high yield, farmers generally use a large amount of base fertilizer, and oft...

Problems solved by technology

[0003] Because cabbage has the characteristics of long growth period and large nutrient demand, it is generally difficult to meet its growth demand under the condition of one-time application of conventional fertilizers. Therefore, in order to achieve high yield, farmers generally use a large amount of base fertilizer, and often need to top-dress the cabbage several times in the later stage. , which will cause a large loss of nutrients, resulting in eutrophication of surface water, excessive nitrate content in groundwater and cabbage, and N 2 A series of environmental problems, such as the increase of greenhouse gas emissions such as O and NO, not only lead to serious waste of resources, but also affect the yield and quality of cabbage in the long run, and also increase the input of labor
