认识和掌握小麦叶蘖在不同肥力、不同密度条件下的同伸关系,及其生长与水热条件的关系,不仅有一定的理论意义,而且还有一定的实际意义。本文通过1977—1979三个年度、四个播种期(历年均为9月26日、10月1日、10月6日和10月11日)共24块地的冬小麦(泰山四号)试验资料,用数理统计的方法,着重分析和总结了小麦在高肥(亩产800斤以上)、中肥(400—800斤)和低肥(400斤以下)条件下不同密度叶蘖同伸关系及在不同肥力条件、不同密度间(当然品种间也有所异,这里未作分析)其叶令、分芭与热量(温度)、土壤水份之间的关系,提出分蘖对土壤含水率所要求的适宜指标。
Understanding and grasping the relationship between the extension and extension of wheat leaf tiller at different fertility and different densities and the relationship between its growth and hydrothermal conditions not only have certain theoretical significance but also have some practical significance. This article through the three years 1977-1979, four seeding period (calendar year on September 26, October 1, October 6 and October 11) a total of 24 fields of winter wheat (Taishan IV) test data , Using mathematical statistics method to analyze and summarize the relationship between the tiller and tiller of wheat with different densities under the condition of high fertilizer (more than 800 kg per mu), medium fertilizer (400-800 kg) and low fertilizer (400 kg) In different fertility conditions, between different densities (of course, there are also differences between varieties, not analyzed here), the relationship between leaf decoction, callus and heat (temperature) and soil moisture, Suitable indicators.
