我国作物栽培科学的发展

作物栽培科学是直接服务于农业生产的一门应用科学。建国后在总结我国丰富的栽培经验的基础上，广泛吸收现代科学技术，逐步建成了独立的科学体系。近十几年来，在区域化、指标化、规范化栽培；周年综合利用自然资源、开拓增产增收途径；提高作物群体光合利用效率及高产栽培；作物高产需肥规律及配方施肥；作物抗逆综合栽培技术；作物栽培机械化、除草化学化、地膜覆盖栽培以及“良种良法”配套栽培等方面取得了很大进展。

THE DEVELOPMENT OF CROP CULTIVATION RESEARCH IN CHINA

Crop Cultivation is an applied science for agricultural production directly. An independent scientific system has been established step by step with widely applying modern science and technology based on summarizing the abundant farming experience in China since 1949.During recent ten years and more, big progress has been made in the following main research aspects: the farming system carried out with regionalization, indexation, standardization and a model using"leaf age index" ; a parth for increasing yield and income through the integrative utilization of yearly natural resources; increasing crop population photosynthetic efficiency and crop production; formularizing fertilizers supplied and the rules for high yield; the integrative techniques for increasing stress resistance; the mechanization, herbicides and plastic-sheet-covered cultivation; and suitable farming techniques for improved varieties, etc.
