breeding program
The breeding plan should determine the tree species and varieties to be bred in the coming year according to the seedling structure planted in the nursery, so as to determine the ways, methods and quantities of seedling breeding.
The determination of breeding plan should refer to the scale and quantity of nursery production, and then determine the breeding cycle and technology according to the requirements of seedling raising. After the plan is made, it is time to start breeding.
Transplant plan
The transplant plan needs to be determined according to the nursery reproduction yield, tree yield and tree planting structure of the previous year, and then the new annual tree species and quantity should be determined according to these factors.
Transplant plan, and then determine the plant spacing and planting area according to the maintenance years, seedling years and growth of different tree species.
Maintenance project
Transplanted seedlings will be maintained after growing in a new place for one year. Maintenance mainly includes water, fertilizer, pests and diseases, cultivated land, weeding, pruning and cold protection. For this part of the arrangement, it is mainly to determine the operation time, workload, labor, materials and process selection.
Beyond the nursery plan
In the new year, there must be some seedlings in your nursery. When the seedlings in the nursery reach the nursery standard in height, thickness and volume, they can be included in the nursery list.
Nursery plan is mainly divided according to tree species and varieties, and then listed separately according to various specifications. When making a plan, we should count the number of seedlings of various specifications. The annual output of the nursery is well budgeted, and this year's output can be predicted through the years of reproduction, transplantation and maintenance.
Employment and materials plan
Planning labor materials can budget production costs. The determination of artificial materials is mainly based on the data of the previous year, and generally there will not be much change. Labor mainly refers to the workload of maintenance and seedling raising, and the materials mainly include fertilizers, pesticides, seedling packaging, cold-proof materials and tools, machinery and fuel needed for these jobs and maintenance. Therefore, the data of the previous year should be kept well, and on this basis, it should be increased or decreased appropriately.
Planting big seedlings plan
Large seedlings refer to seedlings whose specifications have exceeded the nursery standards. If the DBH of deciduous trees is more than 8 cm and the height of evergreen trees is more than 3 m, these trees are all big seedlings.
The planting plan of big seedlings is mainly based on the greening task in the overall planning of urban construction. Because it takes a long time to recover the economic benefits of big seedlings, it is necessary to prepare seedlings several years in advance and then predict the annual growth. If you have the idea of planting big seedlings, you should make preparations several years in advance.
Introduction of seedling planting plan
Some nurseries introduce some seedlings from home and abroad every year, mainly because there are no seedlings in the nursery, or to expand reproduction, or because the fertility of trees is poor, they can only be cultivated by introducing seedlings. The content of the introduction plan mainly includes the varieties, specifications and quantity of introduced seedlings, and the specific values are determined according to the actual situation of the nursery.
