— —Nanjing as an Example
Abstract: It is well known that the planting industry is the foundation of our existence and provides an effective guarantee for people's development. This is especially true for our country, our country is an agricultural production power, and with many people, this means that our country has a higher demand on planting should be. In order to safeguard our country's economic development, the efficient production of planting industry is very important. The structure of the planting industry is crucial. At present, the structure of the planting industry is optimized to ensure that the efficient production of agriculture becomes an important task of agricultural production in China. The optimization of farming in agriculture is a requirement to make farming more satisfying and make it more efficient. But about how to develop the direction of the structure of planting industry, how to carry out adjustment, to make it more be scientific, has been plagued by people, also have not been able to completely solve this issue. The goal of this article main research methods in the process of planting industry adjust optimization and perfection, using crop development advantage degree evaluation model, rational analysis to the crops.
