Technical points for planting more summer beans in the mountains

Taking advantage of the low temperature in the mountains, the cultivation of the summer beans (the kidney beans) is listed in the off-season of the vegetable supply from August to September, and the benefits are considerable. The key links that need to be paid attention to are:

1. Variety selection and seed treatment should use disease-resistant varieties, such as 豇28-2. Before sowing, soak seeds with 40% carbendazim 1000 times for 12 hours.

2. Site preparation and fertilization select land with deep soil layer and good irrigation and drainage conditions, and turn over the land. Apply organic fertilizer of 5,000 kg to 10000 kg per mu and 50 kg of superphosphate.

3, suitable for the appropriate amount of sowing in mid-May to early June. The row spacing is 70 cm × 25 cm, planting 5000 to 5500 piers per acre, 3 to 5 seeds per pier, and 2 kg to 2.5 kg per acre.

4. Strengthen field management, avoid timely cultivating after falling flowers and slow seedlings, and apply 1 in seedling stage.

The second slow seedling fertilizer can apply 40 kg of decomposed bean cake or sesame sauce per acre. Before flowering, the seedlings are mainly used, and the fertilizer and water should not be too large. In case of drought, water should be poured in a proper amount to keep dry. After the pod is set, the fertilizer and water supply should be strengthened, and 20 kg of quick-acting compound fertilizer per mu should be applied. If the supply of fertilizer and water is timely, the first peak of production in mid-to-late August will continue until September. If there is water pouring condition, it can be combined with watering for topdressing, and the waterless pouring condition can be used for rain and topdressing.

5, when the pruning plants have 5 to 6 true leaves, they should be laid in time, and the vines are put on shelves when the plants are vines. At the same time, all the side branches below the first inflorescence are erased to concentrate nutrients. For the side branches of the first inflorescence above the main inflorescence, leave 2 to 3 leaves to pick the heart. When the main vine grows to 15 to 20 knots and the plant height is 2 to 2.2 meters, it is necessary to pick the heart in time.

6. Prevention and control of pests and diseases In the early stage of plant growth, 1000 times of omethoate solution can be sprayed to control aphids. Land plots with serious damage to underground pests should be timely controlled. In the peak period of pod-forming, if there is damage caused by pea pods, it is necessary to spray phoxim 1000 times solution or BT emulsion 600 times to 800 times in time for prevention and treatment. From July to August, coal pollution is serious. It can be sprayed with 50% more bacteria 600 times to 800 times liquid or 75% methyl thiophanate 1000 times solution in the middle and late July.

7. 10 days to 12 days after timely harvesting, when the pods are full and the seeds have not been exposed, it is suitable for harvesting. There are 2 pairs to 5 pairs of flower buds in each inflorescence of the beans. When picking the fruit pods, do not damage other young pods and flowers on the inflorescence. The second one should be collected early so as not to affect the pod rate.

PRF Tube

PRF extracted with PRF Tube contains collagen and collagen junction protein, which have various biological activities and can promote the adhesion and growth of cells, and cell adhesion is a necessary condition for the maintenance of body structure and the completion of cell growth. PRF has been used in research in the fields of wound healing, oral implantation, wound treatment, and regenerative medicine, showing a wide range of application prospects. PRF facial fat transplantation proves that PRF and autologous fat particles can significantly reduce fat absorption after transplantation. It is rich in platelets with the ability to regulate tissue repair and a variety of cytokines released after activation, which improves the survival rate of transplanted fat.

The preparation of PRF is simplified, with no need to add any anticoagulant, thrombin, and other exogenous substances, and it is completely derived from its own materials, thus avoiding the possibility of immune rejection and allergic reactions. At the same time, it also has the function of slowly releasing growth factors. Release of growth factors in the body for up to a week
