Problems solved by technology

However, there are also certain disadvantages in the preservation of large field planting resource nurseries. It is manifested that the cross-pollination crops preserved in the field must be planted in isolation, or bagged and artificially pollinated to prevent natural hybridization, and it is difficult to apply them on a large scale in breeding or production.
In addition, kraft paper or sulfuric acid paper is used for bagging, which has poor air permeability and high temperature in the bag, which often causes the flowers to be pollinated to be scorched; at the same time, the light transmission is poor, which affects the growth and development of flowers and leaves in the bag
Furthermore, planting and preservation needs to occupy a large area of ​​land, requiring huge manpower and financial resources for long-term management, and the number of preservation is limited. If natural disasters such as diseases and insect pests are encountered, there is a danger of complete destruction.

Abstract

The invention relates to a net room apparatus and a potting apparatus for preservation of woody fruit tree germplasm resources. The net room apparatus comprises a framework, a separation net, and double-faced bi-directional zippers. The framework comprises steel tubes and connecting pieces, wherein ends of the steel tubes are connected through the connecting pieces. The separation net comprises a top separation net and a periphery separation net. Four edges, joining to the ground, of the net room are provided with lead wires corresponding to the separation net, and other edges for forming the net room are provided with the double-faced bi-directional zippers corresponding to the separation net, wherein each double-faced bi-directional zipper is pulled shut in an opposite direction and is pulled open in a reverse direction. The potting apparatus comprises a storing hole, a rotary table, and a potting device, wherein the bottom of the storing hole is provided with the rotary table, and the rotary table is provided with the potting device. The invention further relates to a preservation method of woody fruit tree germplasm resources. The apparatuses have beneficial effects of reasonable design and simple structure, are convenient to disassemble, change, and randomly assemble, and can be widely applied to preservation of woody fruit tree resources garden germplasm.

Description

technical field [0001] The invention relates to a device and a preservation method for preserving germplasm resources of woody fruit trees, in particular to a net room, a potting device and a preservation method for preserving germplasm resources of woody fruit trees. Background technique [0002] The narrowness of the genetic basis of woody fruit trees and the progress of breeding work make the collection and preservation of germplasm resources more and more important. It is expected that in the future fruit tree cultivation, the richness of woody fruit tree germplasm resources and the depth of related research work will determine the breeding advantages in this field. Compared with other preservation forms, the preservation of germplasm resource nurseries planted in large fields belongs to the open-air near-natural preservation. The plants carry out normal life activities and can directly carry out identification and evaluation of botanical characters, agronomic traits, ec...
