小麦穗行圃是小麦“三田”(即穗行圃、原种田、良种田)建设的基础。通过有组织、按计划、分步骤的“三田”建设,恢复了当地主栽骨干品种的纯度和种性,充分挖掘了良种的增产潜力,从而达到小麦增产增收的目的。笔者根据小麦穗行圃生产技术操作规程标准,总结多年来建设小麦穗行圃的实践,就建设技术与同行们探讨。1 选穗穗,打基础1.1 确定数量一般按当地万亩小麦生产大田,依照1:20:600的“三田”繁育比例,确定穗行圃建设面积。再按每亩1200～1500穗,计算需要选穗
Wheat ear nursery is the foundation for the construction of wheat “Mita” (ie spike nursery, original farming, good farming). Through the organized, planned and step-by-step construction of “Mita”, the purity and species of the main cultivars in the local area have been restored and the yield potential of improved varieties has been fully tapped so that the yield and income of wheat can be increased. The author according to wheat ear row nursery production technology standards, summarize the practice of building wheat ear sprouts over the years, on the construction technology and colleagues to explore. 1 selected spike, laying the foundation 1.1 to determine the amount of the general production of local acres of wheat field, in accordance with the ratio of 1: 20: 600 “Mita ” breeding, to determine the construction area of spike nursery. Press 1200 ~ 1500 acre per acre, calculate the need to choose ear
