Problems solved by technology

Then, in the process of promoting conservation tillage technology, in the past, the suitable model was mainly screened through field experiments in the area to be implemented. Although the results obtained by this method are relatively intuitive, it takes a long time and high input cost, which limits the application of the model. Type and scale of experiment

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0035] Such as figure 1 As shown, the conservation tillage mode selection method provided by the invention comprises the following steps:

[0036] 1) Data collection. According to the characteristics of mature areas of conservation farming and the differences in the equipment and techniques used, they are divided into different modes of conservation tillage, and soil data, climate data, geographical data, production habits and other important data of mature areas are collected. Conduct inspections and surveys on areas where conservation tillage is to be implemented, and collect soil data, climate data, geographic data, production habits and other important data in these areas.

[0037] 2) Mode selection preparation. According to the detection and survey data in mature areas, determine the decision-making units and indicators of each conservation ti...

Abstract

The invention relates to a method for selecting a protective farming mode, which is characterized by comprising the following steps: 1) data collection: soil data, climate data, geographic data and production habit data of a mature area and an area to be implemented in different modes are collected; 2) preparation of mode selection: a decision unit and an index of each protective farming mode are determined according to the data of the mature area; 3) construction of a projection pursuit analysis model; 4) construction of a similarity evaluation model; 5) model selection: the protective farming mode corresponding to the mature area with the highest similarity to the area to be implemented is selected as the protective farming mode of the area to be implemented according to the level of similarity. The invention selects a proper protective farming mode for the area to be implemented by constructing a protective farming mode selection mode, and the whole process is completed by computer analog simulation without field experiment, thereby improving the efficiency of protective farming mode selection, and reducing the cost for popularizing protective farming.

Description

technical field [0001] The invention relates to a pattern recognition technology, in particular to a method for selecting a protective tillage pattern applied in agricultural production. Background technique [0002] Conservation tillage is a new type of dry land farming method, which mainly includes no-tillage sowing and fertilization, subsoiling, weed control, straw and surface treatment. Its core is no-till sowing, and the main operations are all done by machinery. Conservation tillage technology originated in the United States in the 1930s. At present, countries such as the United States, Canada, and Australia have basically adopted conservation tillage supported by mechanization, and achieved good results. [0003] Conservation tillage has only been systematically tested and researched in China for more than ten years, and certain results have been achieved in some typical areas, and a series of conservation tillage models suitable for specific areas have been summed u...
