Problems solved by technology

[0003] At present, in the process of turmeric production, no attention is paid to the law of its fertilizer demand, and chemical fertilizers are abused, resulting in serious fertilizer loss and low utilization rate. At the same time, agricultural non-point source pollution is aggravated and the ecological environment is affected.
In addition, drug farmers rely on compound fertilizers or undecomposed farmyard manure for a long time, which can easily lead to plant burning, breeding of soil pathogenic microorganisms, damage to the soil micro-ecological structure, and then affect the nutrient supply of plants, resulting in poor quality of medicinal materials and causing serious damage to the local environment. influences
Research on turmeric mostly focuses on the impact of fertilizers on turmeric production, while ignoring the quality of turmeric. For example, research such as Li Longyun pointed out that organic fertilizers have the greatest impact on turmeric production, followed by superphosphate, and finally potassium chloride. , also have reported high-yield and high-quality green silk turmeric fertilizer application method, such as patent CN110278754A, but yellow silk turmeric and green silk turmeric belong to different medicinal varieties, the composition difference is large, and the nutritional requirements of plants are completely different, which is verified by experiments The patent CN110278754A fertilizer application method is not suitable for yellow silk turmeric, and high-yield and high-quality yellow silk turmeric cannot be obtained by this method

Abstract

The invention relates to a fertilizer combined application method for improving the yield and quality of radix curcumae longae. On the basis of base fertilizer application, the following fertilizers are applied in proportion: 16.11-22.64 kg of nitrogen fertilizer, 67.96-92.04 kg of phosphorus fertilizer, 12.35-22.48 kg of potassium fertilizer and 35.82-53.24 kg of organic fertilizer in each 667 m<2> of cultivated land. By adopting the fertilizer combined application method, the obtained radix curcumae longae is high in yield and good in quality, wherein the yield per mu of the radix curcumae longae is 120 kg or above, the total ash content of the radix curcumae longae is lower than 9%, and meets the total ash content index of the medicinal material radix curcumae longae specified by the 2015 edition of Chinese pharmacopoeia, the content of extract is greater than 20%, and the content of curcumin is greater than 0.08%. The fertilizer combined application method is applied in productionpractice, the yield can be improved, and furthermore, the contents of the extract and the curcumin can be improved, and the fertilizer combined application method is a combined application method withrelatively high safety.
