Research On Annual High-quality, High-yield And High-efficiency Technology Of Rice And Wheat In Jiangsu Coastal Reclamation Area

Rice and wheat are two major food crops in China,and Rice-wheat rotation system is the basic planting system in southern China and Jiangsu Province.In Jiangsu Nongken Group Co.,Ltd.,almost 95%of the planting area uses rice-wheat rotation system,the rice and wheat planting area in coastal reclamation area accounts for about 65%of Jiangsu's agricultural reclamation.Therefore,it is of great significance to study the annual high-yield and high-efficiency production of rice and wheat.However,In recent years,the popularization of small seedling mechanical transplanting technique and bowling seedling transplanting technique,the application of late-maturing rice varieties,and the late sowing of rice and wheat have resulted in greedy and late-maturing of rice and wheat,increased pests and diseases,increased risk of ear sprouting and lodging,great difficulty in drying and drying,and aggravated the tension of the growing season of rice and wheat and affected the high and stable yield of annual rice and wheat.Taking the annual high yield and high efficiency of rice and wheat in coastal reclamation area as the research content,taking the utilization of rice and wheat varieties in different ecological regions as the core,Based on the cultivation tests of rice and wheat,this study referred to the technical summary of the high-yielding production of rice and wheat in the reclamation area of Jiangsu Province and makes comprehensive utilization of quantification of rice-wheat growth process and organ-building diagnosis,quantification of dynamic index of high-yielding population and quantitative cultivation technology to form a production technology to ensure that the whole process of rice and wheat production control technical indicators are precisely quantified:(1)According to the growth characteristics of rice and wheat varieties,the varieties of rice and wheat in different ecological regions should be popularized reasonably.(2)The high yield and high efficiency cultivation pattern of rice and wheat with different ecological conditions in Jiangsu reclamation area are constructed with the emphasis on planting pattern,variety,continuous cultivation,optimization of cultivated land.(3)With high yield,high efficiency and timely stubble as the core,mechanization and simplification and precision as the methods to establish rice and wheat annual high-yielding cultivation techniques.
