The invention belongs to the technical field of agricultural planting, and in particular discloses a method for planting pearl guavas, which comprises the following steps: (1) the planting garden for the pearl guavas is planned, gutters are dug to drain stagnant water and reduce underground water level, a gutter is dug every 6.5 to 7 meters in the garden, the row spacing of plants in each border is between 3.5 and 4 meters, the row spacing of plants on two sides of the gutters is three meters, the space of the plants is between 2.5 and 3 meters, the plants are all planted through supporting piers, the height of the piers is between 25 and 30 centimeters, the pearl guavas are grafted, bred and fixedly planted mainly in spring; (2) fertilizer is applied, wherein the pearl guavas are fertilized by taking earthworm excretion as the basic fertilizer and are sprayed by microelement foliage fertilizer such as zinc, boron and molybdenum after fertilizer; and (3) field management work is carried out, including 1. controlling the time of fruiting of young trees, 2. reasonably keeping fruits and controlling the flowering and fruiting, and 3. wrapping the fruits by bags. The pearl guavas planted by the method have incrassated and broad leaves, big and stout fruits, sweet taste without acid taste, good color and luster of the fruits, juicy and crisp pulp, good mouthfeel and high yield, are suitable for standardization planting on a large scale.

The invention provides an embedded double-line central oxygen supply lifesaving system for a mine refuge chamber. An embedded mine refuge chamber lifesaving cabin body is arranged inside a mine chamber; the cabin body is a sealed inflated flame-retarding double-layer lifesaving cabin body; a compressed air pipeline port running through the cabin body and a communication data line interface are arranged on the cabin body; and a double-line central oxygen supply lifesaving system, a carbon dioxide absorber, a power carrier communication device, a UPS power source, an RFID personnel identification system, a video safety monitoring system, an automatic toxic and harmful gas detector, a sealed physiological excretion discharger and a survival food storage cabinet are arranged inside the cabin body. The double-line central oxygen supply lifesaving system is connected with central air and oxygen supplying masks and is connected with the compressed air pipeline port. The power carrier communication device is connected with the communication data line interface. The embedded double-line central oxygen supply lifesaving system can provide a shelter, oxygen and living spaces for the mineworkers in the case of mine disasters and can have the functions of saving life and providing refuge; meanwhile, the embedded double-line central oxygen supply lifesaving system is provided with a double-line oxygen supply system.
