(1) Nursery and planting Grafting and propagation, nectarine anvil, seed layering, winter sowing, budding in June-August, or harvesting in the early spring of next year, and the second winter nursery stock can be planted. The plant spacing was 4m×5m or 3m×4m, and 500-840 plants were planted per hectare. The planting period can be from defoliation to germination. Taoyuan must not be contiguous, otherwise the growth of the saplings will be obviously weakened, the leaves will be green, the new roots will be browned, and the branches and branches will flow. This phenomenon of bogey continuation shows a serious performance in sandy soil or in the soil with low fertility. The main reason is that the former residue roots decomposes in the soil to produce toxic substances such as benzaldehyde and cyanate, which inhibits and poisons the root system, and is also related to the proliferation and accumulation of nematodes in the soil during continuous cropping.
(2) The ratio of nitrogen, phosphorus, and potassium needed for fertilized peach is about 1:0.5:1. Juvenile trees need to pay attention to control the application of nitrogen fertilizer, otherwise it is easy to cause leggy. After the fruit period, nitrogen fertilizer is added to enhance tree vigor. The content of potassium in peach fruit was 3.2 times that of nitrogen. Potassium fertilizer was applied to increase fruit production. Results The tree was fertilized three times a year: basal fertilizer was applied during the period of October-November combined with deep plowing of the soil, mainly organic fertilizer, accounting for 50% of the annual fertilization amount; the strong fruit fertilizer was applied during the hard core of the fruit from late April to May. The precocious species were mainly applied with potash fertilizer. The nitrogen application rates of mid-late and late-maturing varieties accounted for 15%-20% of the whole year, phosphorus accounted for 20%-30%, and potassium accounted for 40%; the fruit fertilizer was applied before and after fruit harvest, accounting for the total amount 15%-20% of the year. In addition, Taoyuan requires frequent cultivating and weeding to keep the soil loose, drain water in time, and prevent the accumulation of water.
(3) Pruning is more natural and happy. The dry height is about 60cm, leaving 3-4 main guilders, the main branches open at an angle of 50°-60°, leaving 1-2 main branches for each main branch, and leaving as few twigs as possible on the main branch and sub-main branches. The pruning period includes winter trim and summer trim. Although the initial result tree (3-4 years after planting) has resulted, it grows vigorously, has many branches with long branches, and has dense branches. It is necessary to adopt summer scissoring measures such as wiping shoots, picking hearts, and twisting the tip to suppress the weak and maintain the tree body. Balance; fruity peach trees, due to many years of results, tree vigor has eased, leggy branches and secondary branches significantly reduced, the proportion of middle and short fruit branches increased, must be short cut, and remove the dense branches and strong apex Branches, improve lighting conditions between shoots;
The anesthetic mask can be attached to the patient's face, delivering oxygen and volatile anesthetic gas to the patient.
Oxygen Masks are devices that are constructed to supply oxygen or other gases to an individual. Masks of this type fit snugly over the nose and mouth, and are equipped with a tube that connects the Oxygen Mask to a storage tank where the oxygen is contained. The Oxygen Mask is made from PVC, as they are light in weight, they are more comfortable than some other masks, increasing patient acceptance.
The Nebulizers are connected by tubing to a compressor, that causes compressed air or oxygen to blast at high velocity through a liquid medicine to turn it into an aerosol, which is then inhaled by the patient, and the medicine in the form of a liquid solution is loaded into the device upon use. The Nebulizers are commonly used for patients in hospitals who have difficulty using inhalers, such as in serious cases of respiratory disease, or severe asthma attacks, it is also for ease of use with young children or the elderly.
