Beidou navigation global winter wheat satellite zoning expansion and green snow wheat fire belt

Abstract

The invention discloses a novel three-dimensional Beidou navigation global winter wheat satellite zoning expansion and green snow wheat fire belt comprehensive advance method. Base on a deep-snow and constant temperature winter wheat safe green-up life zone of a cold plateau, Beidou navigation firstly performs global winter wheat satellite zoning and planting is expanded. Planting regions are divided into safe regions, relative safe regions, and risk regions. Planting surface expanding-downward life support energy supply intervals are divided into mechanical cultivation intervals and non-mechanical cultivation intervals. According to a filed planting test result of previous winter wheat freezing injury detection, winter wheat is expanded from the safe planting regions to corresponding cultivation depth of the life support energy supply mechanical cultivation intervals below a base line through gradually expanding downward a global winter wheat life safe wintering and green-up guarantee energy supply seeding line, thereby realizing to expand gradually to the relative safe planting regions and then expand to the risk planting regions. The green snow wheat fire belt is a green ecological fire barrier belt of manual cultivation in forests and grasslands in cold plateaus, and is protected by forest climate and accumulated snow, and is the safe region of Beidou navigation satellite zoning expansion planting regions.

Description

technical field [0001] The present invention belongs to the field of intelligent agricultural environment, climate and agricultural production, and specifically relates to the expansion of Beidou Navigation Global Winter Wheat Satellite Division and the comprehensive promotion method of green snow wheat firebreaks, and the establishment of a three-dimensional guarantee framework for global winter wheat life safety, overwintering and greening, and alpine areas Ecological protection of snowy areas The green safe turning green belt of winter wheat is used as a green snow wheat fire belt to isolate forests and grasslands from fire. Background technique [0002] China's Beidou Satellite Navigation System (BDS) is a global satellite navigation system developed by China itself. It is the third mature satellite navigation system after the US Global Positioning System (GPS) and Russia's GLONASS Satellite Navigation System (GLONASS). The supplier identified by the United Nations Satel...

Problems solved by technology

[0014] The purpose of the present invention is to provide a new three-dimensional Beidou navigation global winter wheat satellite division expansion and comprehensive advance method of green snow wheat fire belt, directly locate the safety life zone of winter wheat in the alpine ecological protection snow area, and find the life safety of winter wheat Overwintering and turning green to ensure the critical point of the surface, delineate the baseline of winter wheat life safety, overwinter and turn green to ensure the surface baseline, establish the winter wheat life safety and turn green to ensure the energy supply interval, use satellites to first divide and then expand winter wheat planting, and its scope will be gradually divided into cold areas. Expand planting around the world, and use the freeze damage inspection and value method to achieve safe overwintering and greening of winter wheat, and make the complicated science of winter wheat development simple and practical, so as to solve the problem of greening of winter wheat in the same plot, the same variety, and the same planting method in the alpine area. Stability phenomenon (the world problem of good greening in some years, poor greening in some years, and death in some years), finding the irresistible cause of death of winter wheat, taking into account the three-dimensional environment and climate, and delineating the life expansion of winter wheat through satellite zoning Safe areas, relatively safe areas and risk areas and corresponding planting models, have successively used the safe turning green belt of winter wheat in the alpine area for ecological protection as the green snow wheat fire protection belt of forest and grassland for fire isolation application, and started the China Beidou Navigation Global Winter Wheat Project , creating an effective new model for the world to expand the planting of winter wheat in the alpine region, realize the maximum expansion of the planting area of ​​winter wheat in the alpine region, and contribute to world food security and environmental protection
