三江平原主产小麦大豆,该地区分布较广的土壤有草甸白浆土、草甸土和草甸黑土,由于经常发生小麦不孕而影响农业生产,研究其发生原因和防治措施,对提高和稳定小麦产量,有重要意义。根据我们调查,小麦不孕病常发地块及其发生程度,是与土壤类型、气象变化、耕作质量乃至施肥和品种都有关系,它们之间又是互相联系,致使小麦不孕病十分复杂。多年试验证明,引起小麦不孕主要是土壤中有效硼铜锌等微量元素供应不足所致,而气候、耕作、施肥以及品种的更替是其外界条件。
Sanjiang Plain, the main production of wheat and soybeans, the distribution of the wider areas of the soil are meadow albion soil, meadow soil and meadow black soil, due to frequent occurrence of wheat infertility and affect agricultural production, to study the causes and prevention measures to improve And to stabilize the wheat yield is of great significance. According to our survey, the frequent occurrence of wheat infertility land and its occurrence is related to soil type, meteorological change, tillage quality and even fertilization and variety, and they are also interrelated with each other, making the wheat infertility complex . Years of testing have shown that the main cause of wheat infertility is due to insufficient availability of trace elements such as boron, copper and zinc in the soil, while climate, farming, fertilization and the replacement of varieties are the external conditions.
