A Detailed Guide to the Latest Cultivation and Management Methods for Solomon's Seal
Solomon's seal (Polygonatum odoratum) is a perennial herbaceous plant in the Liliaceae family and also a commonly used traditional Chinese medicinal herb. At present, the main cultivated varieties of Solomon's seal are Xiang Solomon's seal, Haimen Solomon's seal and Xi Solomon's seal, and there are also two relatively common wild varieties: Guan Solomon's seal and Jiangbei Solomon's seal. In fact, the cultivation technique for Solomon's seal is very simple, but if you want a high yield, you still should not overlook its management techniques. So today what we are going to learn about is the cultivation and management techniques for Solomon's seal. Let's take a look together.
1. Density management
Solomon's seal is generally planted in April or October each year, and when planting, its planting density is also worth our attention. A reasonable planting density can, to a large extent, help avoid the occurrence of some diseases. Generally speaking, the best planting density is a row spacing of 30 to 40 cm and a plant spacing of 15 to 20 cm. At the same time, it is also relatively convenient for us when carrying out field operations, and it can also reduce a certain amount of labour.
2. Intertillage and weeding
Solomon's seal has a relatively long growth cycle, and generally it will not emerge in the first year after planting; it will only emerge in the spring of the second year. After Solomon's seal emerges, we need to start intertillage and weeding. When we first start weeding, we all use shallow tillage or pull out the weeds by hand, and we must ensure there are no weeds in the field. By the third year, its rhizomes grow and are distributed densely, so in order to avoid damaging the tubers, we can only weed by pulling them out by hand. If the soil becomes compacted, then we should also loosen the soil and earth up appropriately, so as not to affect the yield of Solomon's seal.
3. Fertiliser and water management
Although Solomon's seal is a plant that needs high fertiliser for high yield, generally, when the base fertiliser has been applied sufficiently, no topdressing is needed in the first year. But if the growth rate of Solomon's seal is very slow and the leaves show yellowing, this is usually a sign of malnutrition, which means it is time to fertilise. When topdressing, we mainly use manure and urine water, together with farmyard manure, cake fertiliser, phosphate fertiliser, etc. What to note is that nitrogen fertiliser should be avoided as much as possible, because Solomon's seal is very sensitive to nitrogen fertiliser. During the growth process of Solomon's seal, we should water it from time to time, with the specific situation determined according to the rainfall conditions at the planting site and the growth condition of Solomon's seal, and carry out timely drainage treatment when necessary.
4. Pest and disease control
During the cultivation process, the prevention and control of its pests and diseases is also something we need to pay attention to. For example, leaf spot disease, root rot, grey leaf spot and purple ring disease are four relatively common diseases, and we can use Bordeaux mixture, carbendazim, chlorothalonil, trichlorfon and other chemicals respectively to prevent and control them. Secondly, the pest white grub also causes relatively great harm to Solomon's seal, so we should spray to kill it in a timely manner, so as not to affect the yield and quality of Solomon's seal.
The above is all the content that the editor wants to share with you today.
