强筋小麦新麦19号种植模式研究

Studies on the Plant Models of Strong Gluten Wheat Xinmai 19

在强筋小麦单位面积播量既定时,生长前期小行距的单株生长有一定优势,拔节期以后减弱;小行距使基部节间长度增加,植株偏高,抗倒性下降。随着行距增大,单位面积的成穗数呈现先增后减的趋势,行距偏小时千粒重降低。在豫北高产麦区,强筋小麦新麦19号以23 cm等行距种植产量最高,行距偏小或行距过大时都会造成减产。

Strong gluten wheat Xinmai 19 in the sowing rate on the unit area decided, the plant growth of small row spacing contains certain advantage in initial growing stage and dies down after elongation stage;The small row spacing makes length of lower stanza and plant height increase, and counteracting lying flat descend. Along with the row spacing becoming larger, the ears of wheat on the unit area reduces after it increases first, 1000 - grain weight of the smaller row spacing reduces. In high -yield cornfield in north I-Ienan province, Strong gluten wheat Xinmai 19 ,the yield of 23era equal row spacing plant mode is the highest, the yield of smaller row spacing or bigger row spacing reduces.
