铜仁地区的小麦产量历来不高,解放前平均亩产只有40—50斤。解放后虽经过多年生产技术改革,使平均亩产逐步提高,但仍然属于小麦低产区之一。 造成小麦低产的原因,除耕作管理粗放,肥料不足以及病虫害严重外,气候条件也有重大影响。本文仅从气候角度对小麦低产的原因及提高产量的途径加以简述。为了便于说明铜仁地区气候条件对小麦产量的影响,这里引用我国小麦高产区之一的北京地区
The output of wheat in Tongren area has not always been high, and the average yield per mu before liberation is only 40-50 kg. After many years of post-liberation technological and technological innovation, the average mu production has gradually increased, but it still belongs to one of the low-yielding wheat areas. The causes of the low yield of wheat, in addition to extensive farming management, inadequate fertilizers and pests and diseases, the climatic conditions also have a significant impact. This article only briefly describes the reasons for the low yield of wheat and the ways to increase the yield from the perspective of climate. In order to explain the influence of the climatic conditions in Tongren on the yield of wheat, this paper cites the Beijing area, one of the high-yielding areas of wheat in our country
