Latest Key Points of Field Management Techniques for Rosemary
Rosemary is grown over a very wide area in our country, although it is not a plant that can be eaten directly. However, after processing it can be made into various spices for use in all kinds of dishes, and it can also be crushed and soaked in hot water to drink, with various effects such as calming, promoting urination, treating headaches, and aiding digestion. Rosemary has a relatively long growing period, so we need to strengthen its management. Below, the editor brings you the field management techniques for rosemary. Let's take a look!
1. Timely transplanting
After successful propagation by cuttings or other methods, transplant at the right time. Control the planting density well when transplanting; usually the number of plants set out is 4200 plants/mu. Before planting, do a good job of land preparation and fertilization. After applying the base fertilizer, cover it with fine soil, and then the transplanting work can begin. After transplanting and planting, water promptly. Do not use flood irrigation, to prevent the seedlings from lodging due to too much impact. If lodging occurs, straighten them promptly. Do not transplant in weather with excessively strong sunlight or excessively high temperatures, to prevent the seedlings from failing 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 can grow continuously, so after each harvest, apply nitrogen and phosphorus fertilizer once. Increase the nutrient ratio to promote the growth of new rosemary, but pay attention to the amount of fertilizer; do not use excessive amounts, otherwise excessive vegetative growth and root burning are likely to occur.
3. Shaping and pruning
The pruning work for 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 intensity of pruning; do not prune heavily or severely, as excessive pruning can easily cause the plant to lose the ability to sprout again. The maximum length of each pruning must not exceed half of the branch. Every leaf axil of rosemary has the ability to grow small buds, and these small leaves will gradually grow longer as the branches grow. If they are not handled in time, after growing longer these small buds will cause the plant to become messy and the plant to close up, triggering various diseases and insect pests. 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, and one planting can be harvested continuously for many years. The main harvest targets of rosemary are the branches and leaves. The harvesting method can be breaking by hand or 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. Therefore, when harvesting, we should avoid the sap touching the skin, and do a good job of disinfecting the plant wounds to avoid infection and 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 the field management techniques for rosemary. Field management of rosemary is very important. Because rosemary grows extremely slowly, it also requires us to manage it patiently. After it matures, you will gradually feel the economic benefits of planting it. 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 to check it out!
