水稻高产栽培技术的发展过程，都是围绕当前、当地影响产量的关键技术问题，针对水稻生长发育过程中稻株与环境条件，水稻的群体和个体及个体内部各器官间的３对矛盾，重点协调好个体内部穗数与穗重的矛盾开展多层次、多内容的技术改革，促使水稻生长发育过程达到苗壮、株健、穗齐、粒多、粒饱，实现高产、高效、优质、低耗的目的．其发展过程可分为５个阶段：１）改革稻田耕作制度，扩大双季稻，应用传统技术经验；２）推广矮秆品种及相应的高产栽培措施；３）推广杂交水稻及稀播、少本插等配套栽培技术；４）总结推广高产栽培模式及中低产田配套增产技术；５）开展吨粮田工程的农业技术及杂交水稻规范化栽培．研究立足水稻高产，关键技术主要是调节水稻与环境相适应，以实现高产．而高产必须正确处理产量因素关系，群体个体关系，生理生态关系以及技术措施的关系．促进水稻生产，改革技术主要抓３条措施：１）改革育秧技术，提高秧苗素质；２）推广合理密植，协调苗、株、穗粒；３）改进施肥方法，注意灌溉技术
The development of high-yielding rice cultivation techniques are the key technical issues around the current and local yield. In response to the three pairs of contradictions between rice plants and environmental conditions, rice populations and individuals and various internal organs, and key coordination Good individual internal ear number and ear weight of the contradiction to carry out multi-level, multi-content technical reform, promote rice growth and development process to achieve Miao Zhuang, Jian Jian, Su Qi, grain and more, full, to achieve high yield, high efficiency, high quality, low consumption the goal of. Its development process can be divided into five stages: 1) reforming paddy field farming system, expanding double cropping rice and applying traditional technical experience; 2) promoting dwarf varieties and corresponding high-yielding cultivation measures; 3) promoting hybrid rice and thinning and less sowing 4) summarize and popularize high-yielding cultivation mode and middle and low-yielding field supporting stimulation technology; 5) carry out agricultural technology of ton grain field project and standardization cultivation of hybrid rice. Research based on high-yielding rice, the key technology is mainly to adjust rice and the environment to adapt to achieve high yield. The high yield must correctly handle the relationship between yield factors, group individual relations, ecological and ecological relations and technical measures. Promote rice production, the reform of technology is mainly focused on three measures: 1) the reform of seedling raising techniques to improve the quality of seedlings; 2) to promote the rational close planting, seedlings, strains and spikes; 3) to improve fertilization methods, pay attention to irrigation techniques
