山东小麦高产栽培体系与配套技术

山东小麦高产栽培分精播、半精播、旱作和晚茬麦四大技术体系与八项配套技术（精播、千斤规范、半精播、中产变高产、旱作、晚茬四补一促、独秆栽培和稻茬盖播）。这些高产体系和配套技术是指在一定的播期范围内和不同的土、肥、水等生产条件下，以冬前积温为依据，以调整合理的群体起点为开端，以建立合理的群体动态结构为中心，以提高光能利用率，求得穗、粒、重最大乘积为目的，以相应的综合配套技术为手段，来协调小麦高产生育与环境条件关系的统一。其中控制小麦的叶蘖生长与合理的群体动态结构，掌握栽培体系的技术特点是高产栽培的关键。本文较详细地介绍了适期播种的冬小麦叶蘖生长规律、群体结构及四大栽培体系的技术特点。

Establishing Cultivation Systems and Comprehensive Techniques to Get High Yield of Wheat in Shandong Province

In Shandong Province, four cultivation systems and eight comprehensive techniques had been put forward, which could be used to increase efficiency of light energy utilization thus getting the maximum yield by adjusting population size according to different conditions such as soil,fertilization, irrigation, seeding time,accumulated temperature before winter and so on.The key technique for high yielding was to control the growing of leaf tillers, rationalize dynastic population structure and grasp the culture techniques. Here,growth regularity of leaf tillers and population structure of winter wheat seeded on suitable time, and the four cultivation systems are introduced in detail.
