| 摘 要： | 本文根据全省、运城地区以及几个典型县的从1952年起,近30年的小麦单产资■分析了我省小麦产量变异的特点和变异的原因,从而提出我省小麦大面积提高单产的可行对策:(1)立足于占麦田总面积70％的旱地,以改变我省小麦产量不高、不稳、不平衡的落后状况。(2)充分、有效地保住和利用伏雨,用以奠定小麦丰收的水份基础。其途径是加强以提高地力为中心的农田基本建设;推广传统的,久为实践证明有效的耕作保墒措施。(3)在栽培管理方面,以提高穗数为主要目标,采用培育壮苗的成套措施。(4)选育抗寒、对旱地适应性强、分蘖多、成穗率高的新品种。

An Available Policy of Improving The Total Yield of Wheat of Shanxi |
| |
| Abstract: | Basing upon the records of wheat yield per unit area of shanxi, during the period of about thirty yearts since 1949, the characteristics of the fluctuations of wheat yield/area by year and their causes are analyzed. As a result, an available policy of improving total yield of wheat within the provine is developed: (1)In order to eliminat the present situations of low level, unstable and unbalance of wheat yield, best effort must be given to the wheat field on unirrigated land which occupices about 70％ of the total area. (2)Te establish a sound base for growing of wheat seedlings, the summer rainfall must be fully preserved in the soil and effectively utilized by the plants. The only way of achieving such requirements is try to improve the soil fertilily and extending the traditional cultural practices of preserving soil moisture. (3) A set of agro-technical practices adopted for the aim of establishing healthy seedlings before winter is needed. (4) Breeding new verieties of hard-resistence, high adoptability with arid conditions, better tillering and higher rate of heading. |
