The term "Mai Dong" from Ben Cao fen is sweet, slightly bitter and slightly cold. Moisten lung and clear heart, purge heat and promote fluid production, resolve phlegm and stop vomiting, cure cough and promote diuresis. Modern pharmacological research also shows that radix ophiopogonis mainly contains ophiopogonin, steroid saponin, alkaloid, sitosterol, glucose, amino acid, vitamin and the like, and has the effects of resisting fatigue, removing free radicals, improving cellular immune function and reducing blood sugar. In addition, the radix ophiopogonis has the effects of calming, hypnotizing, resisting myocardial ischemia, resisting arrhythmia, resisting tumors and the like, particularly has various effects on promoting the health of old people, and at present, the roots of the radix ophiopogonis are listed as homology of medicine and food, so the radix ophiopogonis has wide application and needs to be planted in a standardized way.
Fucheng dwarf lilyturf tuber, also called Chuan dwarf lilyturf tuber and Mian dwarf lilyturf tuber, is produced in san Tai county of Sichuan province, and the production area is mainly concentrated in nine towns (villages) centered on garden towns in Fujiang drainage area of san Tai county. In 2006, the national quality inspection Bureau approved the application of geotagged product protection to Fucheng radix Ophiopogonis. The Fucheng dwarf lilyturf tuber has the main medicinal components of polysaccharide, saponin, amino acid and the like, has the effects of nourishing yin, promoting the secretion of saliva or body fluid, moistening lung, clearing away heart fire and the like, and has the advantages of increasing continuous cropping obstacles of the dwarf lilyturf tuber, reducing yield, serious diseases and insect pests, reducing quality and the like due to large market demand, narrow suitable planting area and continuous year planting of farmers in a production area. The method mainly comprises the following aspects:
(1) the fertilizer application types mainly comprise simple substance urea, calcium superphosphate, potassium sulfate, common compound fertilizer, and organic fertilizers such as poultry and livestock feces and straws in peripheral farms, and the fertilizer application types are applied by growers according to experience. The fertilizer application has various varieties and difficult mastering of the dosage, and can not be well coupled with the fertilizer requirement rule and the soil physicochemical properties of the Fucheng dwarf lilyturf tuber, so that the fertilizer is inconvenient to apply, the utilization rate is low, the soil quality is reduced, and the diseases are aggravated.
(2) The pest control mode is mainly to spray chemical pesticide on the leaf surfaces in the later period. The radix ophiopogonis is used as a medicinal material of underground roots and has long continuous cropping time and various underground pests, and the control effect of spraying chemical pesticide on the leaf surfaces of the radix ophiopogonis on the underground pests is not good, and the environmental pollution is easily caused.
(3) Radix ophiopogonis is usually applied to the root tuber of underground, so that the main measure for promoting the root tuber growth in production is to spray paclobutrazol, and because the fertilizer is used for a long time and the fertilizer is unscientific, the sensitivity of the radix ophiopogonis to the paclobutrazol is reduced, the dosage is large, and the pesticide effect residual period is long.
(4) The conventional fertilization of the radix ophiopogonis mainly adopts common chemical fertilizers, and the soil is low in organic matter content, so that the soil is hardened by acidification and poor in granular structure. The diversity of the microbial communities in the ophiopogon root soil is affected, so that diseases, insects, grasses and pests in ophiopogon root are accumulated.
Therefore, resistance nutrition research aiming at the planting problem of Fucheng dwarf lilyturf appears to be urgent.
