Fertilization technology for standardized production of Chinese herbal medicines
2018-08-06 22:01:32
Fertilizer is an indispensable material for the growth of medicinal plants. It plays a leading role in promoting its growth and development, increasing yield and quality, but it must be paid attention to rational application, and it cannot be applied or abused by fertilization methods of other crops. According to the relevant regulations of standardized and standardized production of Chinese herbal medicines (GAP), the following points are summarized for reference by the majority of pharmaceutical farmers during production.
1. Fertilize according to the characteristics of Chinese medicinal materials
Generally for perennial, especially medicinal plants of roots and underground stems, such as jade bamboo, white peony, etc., mainly applying fully decomposed organic fertilizer, adding 50-70kg of calcium magnesium phosphate fertilizer per acre, adding potassium fertilizer, matching Fertilizers are applied to meet the nutrient needs throughout the growing season. Generally, the whole plant Chinese herbal medicines may be supplemented with nitrogen fertilizer; for Chinese herbal medicines with fruit and seeds, more phosphorus and potassium fertilizers should be applied. In the different growth stages of Chinese medicinal materials, fertilization is different. In the early growth stage, more nitrogen fertilizer is applied, the application rate is less, and the concentration is lower; in the middle growth period, the dosage and concentration should be appropriately increased; in the later stage of growth, phosphorus and potassium fertilizers are used to promote early fruit ripening and full seeds. .
Second, due to soil fertilization
1. Sandy soil should pay attention to the application of organic fertilizers such as manure, compost, green manure, soil and fertilizer, and add clay to thicken the tillage layer to enhance its water retention and fertilizer retention capacity. Top dressing should be applied in small amounts multiple times to avoid loss of too much application.
2, sticky soil, should apply more organic fertilizer, and quick-acting fertilizer for seed fertilizer and early topdressing, in order to promote early development.
3, loamy soil, this soil has the advantages of sand, clay, is the ideal soil for most Chinese herbal medicine cultivation, fertilization combined with organic fertilizer and inorganic fertilizer, according to the needs of various growth stages of cultivars.
Third, the principle of fertilization
1. Mainly use ternary compound fertilizer and use organic fertilizer.
2, based on the base fertilizer with the use of top dressing and seed fertilizer.
3. Apply fertilizer on the basis of applying farmyard manure to improve soil and improve the quality of Chinese herbal medicine.
