The latest course of field management techniques and methods of Radix Glehniae

Adenophora root is the root system of Adenophora root, which is a traditional Chinese medicinal material in China. It has the effects of nourishing yin and clearing heat, moistening lung and resolving phlegm, benefiting stomach and promoting body fluid. It is often used for chronic cough due to yin deficiency, tuberculosis and phlegm, dry expectoration, etc. Good daily management during planting can effectively improve yield and quality. Let's take a look at the field management techniques of Adenophora japonica together with Xiaobian.

1. Intertillage and weeding

After sowing and emergence, the first thing to do is weeding, weeds will affect the growth of seedlings, especially in spring sowing, the emergence time of seedlings before and after grain rain, when the temperature is appropriate, rain is abundant, weeds grow faster. In addition, moderate cultivation combined with weeding can promote the growth and development of seedling roots. After that, several times of cultivation and weeding should be carried out. The depth of cultivation should be deeper each time, so as to keep the soil loose and permeable and promote the growth of roots downward. When the seedlings have grown up, the whole bed surface and covered by its stems and leaves, then the growth of weeds is limited, so there is no need to carry out weeding. When weeds are needed, they can be pulled out manually.

2. Fertilizer and water management

To grow fast, fertilization is an important measure, topdressing 2-3 times a year, the first time can be in the seedlings, after weeding, watering the seedlings with thin manure and livestock water to promote seedling growth. The second time in May to June, 15 kg of diammonium phosphate can be applied per mu; the third time in July, compound fertilizer, the amount of fertilizer depends on the growth status of planting, if the fertility of the soil is poor, the amount of fertilizer can be appropriately increased. Water immediately after each fertilization, so as to avoid excessive fertilizer on the plant stems and leaves caused by burns, affecting the normal growth of adenophora.

3. Pest control

Common diseases of adenophora root include root rot, brown spot and rust, which will affect the yield and quality of adenophora root, and cause plant death when serious, so we should pay attention to disease control. When root rot disease occurs, it can be sprayed with tuijunte; brown spot disease can be sprayed with prohydantoin; rust disease can be sprayed with triadimefon. Insect pests include cutworms, locusts and aphids. cutworms mainly harm root systems and constantly gnaw on rhizomes. trichlorfon can be sprayed for root irrigation control; locusts and aphids gnaw on leaf tissues and can be sprayed with Aimeile or dimethoate.

4. Harvest

From autumn to cold season, it is harvest season of adenophora root. If planted on flat ground, mechanical operation can be used for harvesting, while manual cutting should be adopted for large slope. The harvesting method comprises the following steps of: digging a groove with a depth of 60cm at the end of the plot to expose the root of the adenophora root, lifting by hand, removing the leaves, taking out the shaved adenophora root from the upper part of the head, cleaning, and dividing according to the size.

The above is the introduction of field management technology of Adenophora japonica, I hope to help you, if you want to know more related knowledge, please pay attention to us.
