去年春小麦丰产实验,继续采用领导、工人、技术人员和师生相结合的组织形式,深入探索春小麦高产的生育规律。103.34亩丰产试验田,平均亩产862.77斤,其中26.59亩平均亩产911.32斤。为了研究小麦高产规律,对同品种不同处理下群体结构、植株形态和生理等方面的高产指标进行观测:单株叶面积、叶面积系数;茎叶干重,分蘖消长及成穗;苗、茎、穗动态及适宜比例。同时为了促进穗大粒多,观测不同品种和同品种不同处理间麦穗发育过程;为增加穗粒数和提高粒重,对麦穗不同部位籽粒形成和灌浆过程进行系统观测;于小麦不同生育期内对土壤水分动态、植株体内有效养分及土壤供肥能力进行了速测;从而对小麦高产规律及相应栽培技术措施有了进一步认识。
In spring last year, the experiment of high yield of wheat continued to use the combination of leaders, workers, technicians and teachers and students to conduct in-depth exploration of the law of reproductive growth of high-yielding spring wheat. 103.34 acres of high yield test field, the average yield of 862.77 kg per mu, of which 26.59 mu average yield of 911.32 kg. In order to study the law of high yield of wheat, the high yield index of population structure, plant morphology and physiology under different treatments of the same species were observed: single leaf area, leaf area coefficient; stem and leaf dry weight, tillering growth and panicle; , Panicle dynamics and appropriate proportion. At the same time, in order to promote the growth of spikelets and large grains, the process of wheat development was observed under different treatments and different treatments. In order to increase the number of grains per spike and increase the grain weight, the grain formation and filling process in different parts of wheat were systematically observed. Within the dynamic changes of soil moisture, plant effective nutrients and soil fertility were measured; thus the law of high yield of wheat and the corresponding cultivation techniques and measures have been further understanding.
