1, crop layout is also called "crop configuration". Refers to the types of crops planted in a country, a region or a production unit, their area ratio and regional allocation or field allocation.
2. Crop layout is the main content of planting system, which is related to multiple cropping, rotation, continuous cropping, intercropping and interplanting.
3. Reasonable crop layout depends on natural conditions (such as heat, moisture, topography, etc. )? And social and economic conditions (such as the national, collective and individual demand for agricultural products, per capita arable land, water and fertilizer conditions, etc. )? Based on. It plays an important role in agricultural development.
4. Crop layout should pay attention to economic benefits, increase production and income, pay attention to reasonable rotation, adhere to the combination of land use and farming, and seek advantages and avoid disadvantages, which will ultimately benefit the all-round development of agricultural production.
Principles of crop distribution:
1, concentrated in areas with suitable natural ecological conditions, rich land resources and great production potential; Try to concentrate on areas with good production technology foundation, easy transformation and construction of production basic conditions, less investment and quick results.
2. While planting cash crops in concentrated areas, we should consider the reasonable rotation of crops with grain crops and green manure or leguminous crops, the combination of land use and farming, commodity production and subsistence production, and the degree of food self-sufficiency or the possibility of adjustment.
3. Gradually and appropriately expand the scale of operation, and connect the planting areas of similar cash crops as much as possible, so as to facilitate the adoption of advanced technology, improve management level and organize processing and transportation, and gradually develop in the direction of regionalization and specialization.
