The latest fertilization method of Panax notoginseng
Sanqi is one of the most important medicinal materials in China, which has high medicinal value and health care value, high economic benefit and wide planting area. It will need a lot of nutrients in its growth, so reasonable fertilization is very important when planting, so how to apply fertilizer to Panax notoginseng? Let's take a look at the detailed introduction.
1. Law of fertilizer requirement
The demand for nutrients for the growth of Panax notoginseng is lower than that of other crops, and the demand for potassium is the highest for conventional nitrogen, phosphorus and potassium fertilizer, which is much higher than that of other crops, and the demand for phosphorus is lower. The fertilizer requirement of Panax notoginseng is the peak from August to October, the highest phosphate fertilizer is in December, and the fertilizer demand of 2-3-year-old plants is higher in the flowering and fruiting stage, accounting for more than the general amount of fertilizer application in the whole year.
2. Principles of fertilization
The fertilization principle of Panax notoginseng is based on base fertilizer and supplemented by topdressing, all kinds of fertilizers and nutrients are matched with each other, and foliar fertilizer is sprayed at the same time. In order to cultivate high quality Panax notoginseng, it is necessary to use farm manure and a small amount of nitrogen, phosphorus and potassium compound fertilizer. Generally, the proportion of them is 2 ∶ 1 ∶ 3. We should pay attention to the application of nitrogen fertilizer, too much nitrogen fertilizer will lead to the decline of the quality of Panax notoginseng, and too little potassium fertilizer will lead to the low yield and income of Panax notoginseng.
3. Fertilization method
The fertilization of Panax notoginseng is mainly based on base fertilizer, generally according to the fertility of the soil, 2500-4000 kg of farm manure, 100 kg of superphosphate and 10-15 kg of potassium sulfate are applied per mu. It should be noted that farm manure must be completely mature, otherwise it is harmful to the growth of seedlings and may lead to the death of a large number of seedlings. The mature farm manure was applied 2-3 times a year, with the amount of 2000-2500 kg per mu and compound fertilizer 2-3 times, 10-15 kg per mu each time to promote plant growth. In addition, 0.2% concentration of potassium dihydrogen phosphate solution or other low concentration of trace elements and other fertilizers can be timely sprayed.
