What are the key points of field management for Sichuan lovage? Understand it in one article
Sichuan lovage is a perennial herbaceous plant in the Apiaceae family. Its root system has a relatively strong growth capacity and is accompanied by a fairly rich fragrance. It has a wide planting area in China, and when growing Sichuan lovage, management work is very important. Reasonable field management techniques are the key to ensuring the yield and quality of Sichuan lovage. So how should Sichuan lovage be managed when grown? Below, the editor brings you the key points of field management for Sichuan lovage. Let's take a look!
1. Intertillage and weeding
Intertillage and weeding are very important for the growth of Sichuan lovage. After the seedlings successfully emerge evenly, a shallow intertillage and hoeing should be carried out in time. Then about 3 weeks later, carry out intertillage and weeding again. During intertillage, pay attention to the depth; it should not be too deep, to prevent damaging the roots of Sichuan lovage and affecting growth. During the vigorous growth period of the underground rhizome, carry out the 3rd intertillage. During the cultivation of Sichuan lovage, intertillage should be carried out at least 4 times, with the last time in the spring of the second year. Before intertillage, pay attention to clearing old stems and leaves from the field; after completion, earth up around the roots to improve the cold resistance of the rhizome and promote the rhizome through winter.
2. Thinning and final singling of seedlings
Thinning is to prevent vigorously growing seedlings from crowding each other, competing with each other for the nutrients and water needed for growth, and affecting normal growth. Generally, in March-April each year, when the seedlings have grown to about 12 cm, carry out thinning and final singling of seedlings. During thinning, pay attention to the growth condition of the seedlings. Select healthy seedlings free of pests and diseases, and remove weak and poorly growing seedlings. Then control the planting density well and do the final singling work. It must not be too dense, otherwise the thinning and final singling work will lose its effect. Keep about 10 seedlings per hill.
3. Reasonable fertilization
In the first two years of growing Sichuan lovage, its aboveground part grows relatively vigorously, and the nutrient area forms relatively quickly. Only by producing a large amount of dry matter can the rhizome be guaranteed sufficient vegetative growth. Therefore, when growing Sichuan lovage, we should pay attention to doing a good job in fertilization. Within the first two months after planting, topdress at least about 3 times, and each topdressing can be carried out together with intertillage and weeding. The fertilizer should mainly be decomposed farmyard manure, applied at the mouth of the planting hole. Generally, it should all be applied before Frost's Descent to ensure the effect.
4. Timely harvesting
The harvest season for Sichuan lovage is generally most suitable within about one week around Grain Full in the second year of planting. The harvest time should not be too early or too late. If too early, the underground rhizome has not yet fully matured, which will have a certain impact on yield. However, if harvested too late, the rhizome is too mature and very prone to rotting underground, also causing a decline in yield and affecting the economic benefits of cultivation. When harvesting, pay attention to choosing a sunny day; it must not be done on rainy days. Dig out the whole plant, then remove the stems and leaves, remove the soil, dry it slightly for 2-3 hours, and then process it for market.
The above is a brief introduction to the key points of field management for Sichuan lovage. Pest and disease control and management work for Sichuan lovage is also very important. Common pests and diseases include root rot, stem node moth, and others, which will harm the growth of Sichuan lovage plants to varying degrees.
