Detailed Explanation of Key Field Management Techniques for Rosemary
Rosemary is grown over a very wide area in China, even though it is not a plant that can be eaten directly. However, after processing it can be made into various spices used in all kinds of dishes, and it can also be crushed and steeped in hot water to drink, offering various benefits such as calming and diuretic effects, treating headaches, and promoting digestion. Rosemary has a long growing period, so we need to strengthen its management. Below, the editor brings you the field management techniques for rosemary, so let's take a look!
1. Timely transplanting
After successful propagation by cuttings or other methods, transplant at the right time, and control the planting density well when transplanting; usually the planting number is 4200 plants/mu. Before planting, do the soil preparation and fertilization work well; after applying the base fertilizer, cover it with fine soil, and then transplanting can begin. After transplanting and planting, water promptly, and do not use flood irrigation, to prevent too much impact force from causing the seedlings to lodge. If lodging occurs, straighten them promptly; do not transplant in weather with overly strong sunlight and too high temperatures, to prevent the seedlings from being unable to adapt and dying.
2. Reasonable topdressing
Rosemary does not have a great demand for fertilizer, because rosemary has strong growth ability and is relatively tolerant of poor soil. However, after the seedlings are planted, topdressing should still be done in a timely manner according to growth conditions, soil conditions, and so on. Each time you topdress, do it together with intertillage and weeding, which can promote the soil's absorption of fertilizer. After topdressing, cover the fertilizer with fine soil to improve the soil's ability to retain fertilizer. Moreover, rosemary grows continuously, so after each harvest, apply a nitrogen and phosphorus fertilizer once. Increase the nutrient ratio to promote the growth of new rosemary, but pay attention to the fertilizer amount; do not use too much, otherwise excessive growth and root burning are likely to occur.
3. Shaping and pruning
Pruning of rosemary is carried out continuously. About 3-4 months after successful transplanting and planting, pruning of the branches can begin. However, pay attention to the pruning intensity; do not prune heavily or severely, as excessive pruning can easily cause the plant to lose the ability to sprout again. The maximum pruning length each time must not exceed half of the branch; each leaf axil of rosemary has the ability to grow small buds, and these small leaves will gradually grow longer as the branches grow. If not handled in time, after growing long, these small buds will cause the plant to become messy and the plant to close up, triggering various pests and diseases. Therefore, if the small buds are not cut off, rosemary must also be shaped and pruned regularly.
4. Timely harvesting
Rosemary can be harvested continuously multiple times; one planting can allow continuous harvesting for many years. The main harvest target of rosemary is the branches and leaves, and the harvesting method can be by hand snapping or by using scissors. However, no matter which harvesting method is used, after harvesting pay attention to the sap flowing from the cut. If this sap is not removed in time, it will gradually coagulate and be very difficult to remove. So when harvesting, we should avoid the sap touching the skin, and do a good job disinfecting the plant wounds to avoid infection causing disease. After rosemary matures, it can be harvested at least three times a year, but this depends on the specific situation.
The above is a brief introduction to rosemary field management techniques. Field management of rosemary is very important. Because rosemary grows very slowly, it also requires patient management from us. After it matures, you will gradually be able to feel the economic benefits of planting. That is all for today's introduction. This article is for reference only. If you want to learn more related information, you can visit our website!
