Broad beans are also called Luo Han beans, and it is said that broad beans are one of the items brought back when Zhang Qian left the Western Region. He has a long history of cultivation in my country. And broad beans are not only nutritious, but also have a variety of ways to eat, so they are welcomed by the market. Now that the golden autumn is October, it is precisely the cultivation time of broad beans, so how exactly should it be grown? What are the cultivation techniques? Let's understand it together.
1. Seed selection
Choose high-yield, disease-free, excellent seeds. Before sowing, the land should be dug deep and tilled to make the land soft and conducive to root expansion and sprouting to form root nodules. Reuse of rhizobia inoculation can increase yield. The method of soil inoculation can be used to take about 100 kg of soil from the soil that has been planted with fava beans and sprinkle it in the ditch when sowing.
2. Seedling management
After sowing, cover with soil and cover with straw to maintain temperature and humidity. Treat the diseased plants in the middle of the growth period, remove the diseased debris and weeds, and destroy them intensively. Spray pesticides to control pests and rats, control the moisture, and arrange the shoots. To ensure the normal development of plants. In the later stage, ensure the plant's demand for water, control the density, and maintain the air permeability between the land.
3. Top dressing and watering
After sowing, you should irrigate in time to maintain the required moisture, which can promote early germination. After sowing, the soil should be compacted to prevent lodging of the grown plants. When growing young leaves, it is appropriate to apply some nitrogen fertilizer. During the growth period, it is necessary to apply phosphate fertilizer and potassium fertilizer in time. During the pod formation period, more trace elements should be applied to reduce the phenomenon of flowers and pods and achieve high yields. In the early stage, it is still necessary to ensure drainage and ventilation, to avoid falling flower pods and shriveled beans.
4. Cultivation and pruning
After the emergence of the seedlings should be checked in time, if the lack of seedlings should be replanted immediately. In the seedling stage, we must regularly plowing and weeding, and the soil will be thickened to prevent lodging. Before and after the flowering period, more attention should be paid to the branching of the seedlings. The branch of the broad bean is difficult to pod. The extra branches should be cut off to absorb more nutrients in the main trunk to increase the fruit rate and the fullness rate.
5. Harvest in time
When harvesting broad beans, it can be done in batches, from bottom to top, about once a week. You can save some mature seeds. When the leaves fall, pick the middle and lower part of the pods. After drying, peel the pods to save the broad beans.
In general, there are many techniques to notice when planting broad beans in October. In order to ensure that growers can effectively increase planting yields, these techniques must be mastered.

Lower Limb Locking plate is a kind of implant fracture orthopedics with locking thread holes.
The lower limb locking plate allows the bone to bind to the plate more firmly, so that the reduced limb is more stable. Locking plates were first used in spine and maxillofacial surgery 20 years ago to stabilize fractures while reducing extensive dissection and damage to soft tissues. When the threaded hole in the locking plate is screwed in by a screw with a threaded head, the plate becomes an Angle fixing device. It can have both locking and non-locking holes for different screws to be screwed in. Any plate that can be screwed into an Angle fixed (stable) screw or bolt is essentially a locking plate.
Locking plate system does not rely on bone friction to achieve connection, but completely depends on the interlocking structure of the plate itself. A certain gap between the plate and the bone surface can be left, which can eliminate the adverse effect of heavy pressure contact between the plate and bone, and greatly improve the blood supply and the growth and recovery of the periosteum. The main biomechanical difference from conventional plates is that the latter relies on friction at the bone-plate interface to accomplish plate compression on bone. Stability is maintained by an angularly stable interface between the screw and the plate. Because the locking internal fixator has a stable integrity, the pull-out force of the locking screw is much higher than that of the ordinary screw. It is difficult for a single screw to be pulled out or broken unless all the surrounding screws are pulled out or broken.
