小麦是我国北方的主要粮食作物,1979年小麦面积为43494万亩,单产达到247斤。小麦增产的原因很多,有品种改良的作用,也有生产条件改善与作务技术提高的作用,而本文的目的则在于探讨小麦品种改进在武功地区增产中的作用。认识这一问题有利于正确评价品种的作用,即不把丰产都归功于品种,也不把减产都归罪于品种;有利于既重视品种的作用,又重视生产条件改善与作务技术改进的作用;还有利于改进育种工作,正确控制育种目标,便于培育能充分利用当地条件与发挥当地生产优势的品种。一、资料来源与估算本文所用资料除1950年为武功头道塬品种示范资料外,其它资料均取自西北农学院
Wheat is the main food crop in the north of our country. In 1979, the wheat area was 434.94 million mu, with a yield of 247 kg. There are many reasons for wheat yield increase, there are varieties to improve the role, but also improve the production conditions and improve the role of business technology, and the purpose of this paper is to explore the improvement of wheat varieties in the martial arts area production. Recognizing this issue is conducive to the correct evaluation of the role of cultivars, that is, neither attribution of high yields to cultivars nor blame on the reduction of cultivars. It is beneficial to both emphasize the role of cultivars and to emphasize the improvement of production conditions and improvement of occupational techniques ; But also conducive to improving the breeding work, the correct control of breeding objectives, to facilitate the cultivation of varieties that make full use of local conditions and give full play to local production advantages. I. Data Sources and Estimation The data used in this paper are except for the demonstration data of Wugongduode Plateau Varieties in 1950. All other data are taken from Northwest Agricultural College
