半干旱区影响春小麦产量的关键因素及其调控措施
- Title:
- Analysis and Adjustment on Impact Factors of Spring Wheat in the Semi-arid Area
- Keywords:
- drought; spring wheat; adjustment measures
- 摘要:
- 春小麦是干旱半干旱区的主要粮食作物之一，大力引进推广优良春麦品种；提高播种量，增加成重穗数；充分利用自然降水，保水保墒，是取得春麦高产的重要措施.同时应增加肥料的投入量，特别是磷肥的投入，改当前的施肥方式秋季基肥的施肥方法为“施足底肥适当追肥”的方法，追肥要以叶面喷施液肥为最好，仍是提高春麦产量的突破口.
- Abstract:
- Spring wheat is a main crop in the semi-arid area, and the following measures should be done to ensure its yield.They are respectively: Selecting improved varieties and then popularizing; Increasing seedrate; Utilizating rainwater efficiently; Increasing fertilizer, specially phosphorus fertilizer; Also they include improvement methods of fertilizer.Using liquid fertilizer to spread on leaf would raise wheat production greatly.
