How to grow Ranunculus ternatus well? A detailed guide to the latest cultivation techniques
Ranunculus ternatus is an annual herbaceous plant of the genus Ranunculus in the family Ranunculaceae, and it is also one of the traditional Chinese medicinal herbs. The main part used for medicine is its underground tuber. At present, Ranunculus ternatus is mainly distributed in Guangxi, Taiwan, China, Zhejiang, South China, Hubei and other places, but the yield is not very high, so it is also a traditional Chinese medicinal herb in very short supply on the market. Today, the editor will teach everyone how to grow Ranunculus ternatus well.
1. Site selection and land preparation
Ranunculus ternatus has the characteristics of liking light, tolerating shade, liking warmth, liking moisture, and having strong adaptability to the environment. Generally speaking, the requirements for the planting site are not high, but if you want to grow Ranunculus ternatus well, you still need to be somewhat selective about the planting site. It is usually suitable for planting in fertile soil, with good drainage, abundant and pollution-free water sources, and sandy loam. Next, the issue of sunlight also needs to be considered. It is best to choose sunny mountain areas, flat land, slopes and so on. After choosing the planting site, deep plow the land and combine this with base fertilizer. The base fertilizer is mainly organic decomposed manure, mixed with phosphate fertilizer and cake fertilizer. Finally, break up the soil finely and level it, then make trenches and beds.
2. Propagation methods
There are three ways to propagate Ranunculus ternatus, namely seed propagation, division propagation, and tuber propagation. But no matter which propagation method is used, planting can be done in both spring and autumn. During planting, pay attention to the planting density. For seed propagation, the row spacing is generally about 15 cm, and the seeds are evenly scattered. For division propagation and tuber propagation, the row spacing is 15 cm and the plant spacing is about 10 cm for planting. Finally, just cover with soil and water, then wait for seedlings to emerge.
3. Field management
During the growth process of Ranunculus ternatus, we should pay attention to soil moisture. Generally, it is best to keep it at about 60 percent, so we had better water about once every week. If there is dry weather with higher temperatures and less rainfall, then we also need to water in the morning and evening to achieve the purpose of cooling. Of course, there is still something to note: in seasons of continuous rain, we must drain water in time to avoid waterlogging. In order to increase the yield of Ranunculus ternatus, during its later growth process we should carry out topdressing at least three times. The first time is watering with manure and urine water; the second time is trench application of a three-element compound fertilizer; the third time is mainly phosphorus and potassium fertilizer, combined with foliar fertilizer, to promote tuber growth. Of course, attention should also be paid to intertillage and weeding, removing weeds in time to avoid nutrient loss. When intertilling, cultivate as shallowly as possible to avoid damaging the tubers of Ranunculus ternatus and affecting tuber enlargement.
4. Pest and disease control
Ranunculus ternatus has strong resistance, so it rarely develops diseases, and insect pests are also very few. However, under continuous rainfall without reasonable management, damping-off is also very likely to occur. This means we need to drain water in time. In the early stage of disease onset, Tuzet can be used for control. In addition, southern blight and powdery mildew may occur, and we can use thiophanate-methyl wettable powder and triadimefon respectively for control.
One important reason why Ranunculus ternatus is in short supply on the market is that the planting scale is not large, and another is that the cultivation techniques for Ranunculus ternatus are somewhat lacking. Many people think Ranunculus ternatus is easy to grow and then neglect management, which is also an important reason leading to failure in growing Ranunculus ternatus. If there are friends who want to grow Ranunculus ternatus, you can read the above carefully.
