河西沿祁连山冷凉灌区春小麦气候生态的研究

河西冷凉灌区春小麦增产潜力大,具有光能丰富、温度适中、光温配合好、降水相对集中、有效风速大等气候优势,它可成为我国又一个小麦高产地区。限制该区春小麦生产潜力发挥的气候因素是分蘖—拔节期的干旱和开花—灌浆期的光照不足。本文还提出了相应的提高气候生产潜力的途径。

A STUDY ON CLIMATIC ECOLOGY FOR SPRING WHEAT IN COLD-COOL IRRIGATING AREA OF HE-XI ALONG THE QI-LIAN MOUNTAIN

There are so many climatic potentials to increase the yield of spring wheat in cold-cool irrigating area of He-Xi, such as sufficient light, suitable temperature, light in tuna with temperture, relatively concentraed rainfall and moderate effective wind speed. We are sure that it must be another higher yield area of wheat in our country. Analysis shows that the climatic factors which limit the development of productive potential for spring wheat are drought in tillering-jointing stage and lack of sunshine in blooming and milkfilling stages. Some ways to develop the climatic potential in this district are discussed.
