Crop cultivation is a branch of agriculture. In order to study the relationship between the growth and development of crops and the environmental conditions, the regulation and control technology and its principles as the main task, it is a comprehensive technical science. Its research and application is of great significance to improve the quantity and quality of crop products, reduce production cost, and improve labor efficiency and economic benefit.
Crop cultivation studies the crop growth and development, yield and quality formation rules and relationship with environmental conditions, to explore through cultivation and management, growth regulation and optimization decision and other ways to realize the theory, method and technique of high-yield, high-quality, efficient and sustainable development of science. Crop cultivation is the most basic and important part of agricultural science.
Crop production is the process of the combination of natural reproduction and economic reproduction. Development focus and research progress of crop cultivation science lies in the general rules and key technology of integrated and refined on crop cultivation and crop cultivation in the general theory of basic framework and content system construction. The relationship between crop growth and product formation, crop and environment, crop cultivation and management technology, the three major modules, the general regularity and general applicability of the basic theory and key technology of crop cultivation.

Classification of crop cultivation
Crop species, characteristics vary widely, crop organs that humans need are not the same, and crop production has obvious seasonal (time) and regional (spatial) and crop cultivation technology not only depends on the type of crop, with a crop often different between time and space condition and different characteristics.
In addition to generally dividing into edible crop cultivation, cultivation of economic crops, forage and green manure crop cultivation, cultivation of medicinal crops science, crop cultivation is often further subdivided into rice cultivation science, wheat cultivation, cultivation of cotton, etc.
1) The relationship between crop and environmental conditions
2) The relationship between the individual and the group
3) The relationship between the crop individual organs
3. Cultivation Plants
After artificial cultivation, wild plants have certain production value or economic traits, genetic stability, can be suitable for human needs of the plant. Includes almost all of the crop, which food crops, such as rice, wheat, corn, sorghum,; fiber crops, such as cotton, hemp and so on; oil crops, such as peanuts, rapeseed, sesame etc.; most of the fruit trees, such as apple, peach, pear and so on; vegetable crops, such as Chinese cabbage, radish, cabbage, etc.; and various ornamental flowers. Agronomics is the technology and principle of crop production, field crop cultivation, breeding, soil management, fertilization, plant protection harm prevention, agricultural application, farmland irrigation and drainage, agricultural products of preliminary processing and storage and agricultural production management, etc.
During the germination of crop seeds; crop seed emergence process ; the relationship between the morphology and structure of crop seed and germination and emergence, crops abnormal root roles; the formation process of legume nodules; causes and prevention of lodging and leggy growth period, rape root crop stems produced; dynamic change, growth period of rapeseed and material of cotton removal of fruit branches and occurrence and main difference; cotton, rapeseed, soybean plant type and branch relationship, gramineous crops and dicotyledonous crop leaf morphology difference; leaf growth period and the main crop leaf survival; high yield cultivation should be how to regulate the growth of crop growth center, leaf blade; each packet and leaves of rice and wheat crops function; cotton stem leaf and fruit branch leaf photosynthetic characteristics of brassica product transportation; Each rape leaf function period and function, the paddy rice, the wheat spike differentiation stages; the developmental process of the cotton flower bud differentiation period, gramineous grain crops, seeds of gramineous crop development of and reasons for the uneven phenomenon, beans crops seed formation process, rape seed growth and development and its weight and oil content changes, relationship between the growth of the main stem and branch growth.
