Crop suitability evaluation method based on environment information

Abstract

The invention discloses a crop suitability evaluation method based on environment information. The method comprises crop data acquisition, soil environment information acquisition, calculating condition setting, matching degree calculating and an output result step. Through collecting crop data, a crop information database is formed. A crop database includes a suitable value of a crop environment index and a weight occupied by the index. The soil environment information is collected so as to form a soil environment database. According to the data of the two and through a weight index and a method, a suitable degree value of the soil environment information to crops is calculated so as to guide agriculture production. Data support and a scientific basis are provided for programming, protection, management and decision making of farmland environments of a poor rural area and other areas. A long-term mechanism that rural poor people become rich through their labor is realized.

Description

technical field [0001] The invention relates to a crop planting evaluation method for guiding rural cultivated land, in particular to a crop suitability evaluation method based on environmental information. Background technique [0002] More than 30 years of reform and opening up have enabled hundreds of millions of Chinese people to shake off the label of poverty, but China's poverty alleviation still faces an arduous task. According to the latest data, according to China's poverty alleviation standards, there were still 82.49 million rural poor people in China by the end of 2013, and the problem of lagging development in poverty-stricken areas has not fundamentally changed. When it comes to people's livelihood issues, groups in need often have more and stronger demands, so they need more attention and assistance. In recent years, the problem of "precise poverty alleviation" for the rural poor has become increasingly prominent. Poverty alleviation work must start with solv...

However, the poor rural people who have not yet escaped poverty have land in their hands, and most of them have low production efficiency. They have not really found an effective way to grow high-yield value on limited land! Therefore, in order to improve production efficiency and effectively realize "precise poverty alleviation" for the poor in rural areas, the optimal matching evaluation of soil environment information and crop suitable environment information is carried out in combination with relevant analysis techniques, and the crops suitable for arable land are obtained through scientific calculation methods. It is of great practical significance to guide the evaluation methods of agricultural production and establish a long-term mechanism for rural poor people to get rich through their own labor, and it is also one of the hot spots of current research

[0003] The choice of crops to be planted in rural arable land is generally based on the farmers' own experience or their own needs to choose which crops to plant. There is no scientific guidance method for crop selection. Often the selected crops or varieties do not match the soil properties well, and most of them are due to low production efficiency. , have not really found out how to grow high-benefit value in a limited field.

At present, in China, there are only studies on the estimation of crop planting area and production estimation methods based on the theory and method of crop planting area extraction based on remote sensing and GIS. Although a few places have carried out studies on crop suitability maps of soil based on GIS, It not only obtains the crops suitable for cultivated land from the soil environment information and the suitable environment information of crops through scientific calculation methods, but also obtains the areas suitable for planting crops through the scientific matching method based on the soil environment information and the suitable environment information of crops, so as to combine the two Combined with scientific research, no institution has conducted in-depth discussion and research
