大麦栽培中合理的基本苗数是创造理想群体结构的起点 ,也是获得适宜有效穗数的基础。若基本苗过少 ,遇到烂冬或旱冬年份 ,可能造成年内苗偏少、有效穗不足 ,很难获得高产。然而基本苗过多 ,再遇上暖冬年份 ,致使分蘖过旺、最高苗数难以控制 ,增大倒伏危险性 ,产量不稳。高产栽
The reasonable basic seedling number in barley cultivation is the starting point for creating an ideal population structure and also the basis for obtaining a suitable effective panicle number. If the basic seedlings too little, encountered rotten winter or dry winter years, may result in less seedlings in the year, lack of effective spike, it is difficult to obtain high yield. However, the basic seedlings too much, and then encounter the warm winter year, resulting in tillering over, the maximum number of seedlings is difficult to control, increasing the risk of lodging, yield instability. High-yielding plants
