窄行稀条播对小麦生长发育的影响

Study on Growth and development of Winter Wheat under Narrow Line Sparse Distribution

通过窄行稀条播与常规条播两种栽培方式,对山农9-1和山农9801两个小麦品种的生长发育、形态特征及产量结构进行研究。结果表明;采用窄行稀条播方式能增加小麦的分蘖数、次生根数以及旗叶、倒二叶和倒三叶的叶面积;多穗型品种更适合于窄行稀条播。

The growth and development, main physical characteristics and production output structure of Shan Nong 9-1 and Shan Nong 9801 were studied using narrow line sparse distribution seeding technique and regular distribution seeding technique. The results showed： The number of tillering,secondary root and the area of flag leaf, last second leaf and last third leaf were increased through narrow line technique; wheat of multi-spike is better used for this technique.
