BASIC PRINCIPLES OF DESIGN OF RECLAMATION SYSTEMS FOR THE CULTIVATION OF ROTATION CROPS WITH RICE
Design of reclamation systems has always been one of the main factors to ensure the stability of rice growing. Rice is considered to be one of the most valuable and useful products, which feeds a third of the world's population. Rice is the leader in yield among many crops and the second place on the planet - in acreage. The cultivation of flooded rice is mainly in floodplain lands. Rice is well adapted and coexists in different soil and climatic conditions and can be fertile on lands of different relief. One of the important factors of low fertility of rice production is the lack of constructive component of rice systems and the lack of proper compliance with all technological parameters in the cultivation of rice in crop rotation. An important and quite significant problem of obtaining a high-quality rice crop without reducing the agro resource potential of rice fields, as well as the correct use of all rice products in circulation is based on the General consideration of factors and parameters that create high rates of rice fertility. A review of the design of the network of rice systems of the main rice-growing zones shows their fragmentation, the lack of industry regulation and a unified approach to addressing the issues of rice irrigation. The article gave a General overview of rice irrigation structures, considered the General methods and principles of design, as well as the analysis and the General collection of experience in the design of rice systems reclamation.
