Field Management of Rosemary

Rosemary is widely used in China, although it is not a plant that can be eaten directly. However, after processing, it can be made into a variety of spices for a variety of dishes, and it can also be mashed and soaked in hot water to drink, which has various effects such as calming diuresis, treating headache, promoting digestion and so on. Rosemary has a long growing period, so we need to strengthen our management. The following editor brings you the field management technology of rosemary. Let's have a look!

1. Timely transplanting

After successful propagation by cutting or other methods, it is necessary to transplant in time, and the planting density should be controlled when transplanting, usually the planting number is 4200 plants / mu. Do a good job of soil preparation and fertilization before planting, and after applying the base fertilizer, cover the fine soil on the base fertilizer, you can start the transplanting work. Watering should be done in time after transplanting, and flood irrigation should not be used in the way of watering to prevent seedlings from lodging due to excessive impact. If lodging occurs, it should be corrected in time, and should not be transplanted in the weather where the sun is too strong and the temperature is too high, so as to prevent the seedlings from being unable to adapt to cause death.

2. Reasonable topdressing

Rosemary does not have a great demand for fertilizer because it has strong growth ability and is more resistant to barren. However, after the seedlings are planted, it is necessary to topdressing according to the growth conditions, soil conditions and so on. Each time topdressing is carried out with the weeding work of ploughing and weeding, which can promote the fertilizer absorption of the soil. After topdressing, fine soil should be covered with fertilizer to improve the fertilizer conservation of the soil. And rosemary is sustainable, so it is necessary to apply nitrogen and phosphorus fertilizer for each harvest. Increase the proportion of nutrition and promote the growth of newborn rosemary, but pay attention to the amount of fertilizer, not excessive, otherwise it is easy to grow and burn roots.

3. Shaping and pruning

The pruning of rosemary is carried out continuously, and the pruning can begin about 3-4 months after transplanting. However, we should pay attention to the strength of pruning, do not re-cut strong pruning, excessive pruning can easily cause the plant to lose the ability to germinate again. The maximum length of each pruning can not exceed the average length of the branches. Each leaf axil of Rosemary has the ability to grow buds, and these leaflets will grow as the branches grow. If it is not dealt with in time, these small buds will lead to plant clutter, plant closure, leading to a variety of diseases and insect pests. Therefore, if the buds are not cut off, rosemary should be reshaped and pruned regularly.

4. Timely harvest

Rosemary can be harvested many times continuously, and once planted, it can be harvested continuously for many years. The main harvest object of rosemary is branches and leaves, and the harvest method can be folded by hand or by scissors. However, no matter what kind of harvest method it is, we should pay attention to the juice from the cut after harvest. If the juice is not removed in time, it will gradually solidify and it will be difficult to remove. Therefore, when we harvest, we should prevent the juice from touching the skin, and do a good job of disinfecting the plant wound to avoid infection and cause disease. Rosemary can be harvested at least three times a year when it is ripe, depending on the situation.

The above is a brief introduction of rosemary field management technology, rosemary field management is very important. Because the growth rate of rosemary is very slow, we also need to manage it patiently. Wait until mature can gradually feel the economic benefits of planting, today's introduction is here, this article is for reference only, want to know more related information, you can check on our website!
