苏协粳具有穗大粒多,单位面积颖花数多的特点。我们在同一栽培条件下对苏协粳与日本晴进行对比分析,以研究苏协粳高产的库源特性,分析密度、肥料对苏协粳库源关系的影响,并据此提出苏协粳的高产栽培途径。 (一)库容特性 通常以单位面积的颖花数多少表示品种库容量大小,但有人认为品种间谷壳大小不一样,因而以单位面积颖壳重来表示品种库
Suji japonica has a large number of spikelets, spikelets per unit area number of features. Under the same cultivation conditions, the comparative analysis of SUJA and Nipponbare was carried out to study the characteristics of sink and source of high yield of Japonica japonica. The effects of density and fertilizer on the source and sink of Japonica japonica were analyzed. Based on this, Cultivation approach. (A) The storage capacity usually expressed in terms of the number of spikelets per unit area. However, some people think that the size of chaffs is different between cultivars. Therefore,
