Abstract

The invention discloses a red date tree canopy leaf nitrogen vertical distribution detection method based on remote sensing information and agronomic knowledge, wherein the method comprises the steps: distinguishing canopies of different levels, carrying out distinguishing through labels, and reminding a worker through remarks on the labels, so as to prevent the worker from deviating when inputting data; meanwhile, calculating the optimal vertical distribution state of canopy leaf nitrogen at different levels, so as to effectively improve the production strength; and distinguishing the data after agronomic knowledge analysis, integrating the data belonging to vertical distribution of leaf nitrogen of different levels of canopies, and making the integrated data into a statistical chart which can be intuitively expressed, such as a broken line chart or a histogram and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for detecting the vertical distribution of leaf nitrogen in the canopy of jujube trees based on remote sensing information and agronomic knowledge. Background technique [0002] Due to the serious pollution of the environment at present, the field resources that can grow crops are in short supply, and the existing seasonal climate is changeable, and the productivity of arable land is decreasing day by day. Improving the productivity of the existing arable land is crucial to maintaining food security. During the process, nitrogen is an essential nutrient element for crops. The growth and production of crops not only depend on the amount of nitrogen absorbed by plants from the soil, but also largely depend on the vertical distribution of nitrogen in the canopy. Improving and adjusting the form of nitrogen in the canopy can effectively increase the production ...
