豫西地区常年种植小麦700万亩左右,约占全省麦田面积的10%,其中大部分为丘陵旱地小麦。由于该区十年九旱,致使小麦产量低而不稳。是全省小麦的低产区之一。小麦产量的高低与气候条件的关系十分密切。依据原洛阳地区1950—1986年37年的小麦实际亩产与气候的关系进行分析,表明:气候最差年份,小麦减产率达54.6%(1961年),气候最好年份,小麦增产率为39.9%(1956年)。在37年中,因气候不良造成小麦减产在5%以上的年份有14个,因气候较适宜小麦增产在5%以上的年份有12个。由此可见,不同年份的气候条件对小麦产量的影响是很大的。为此,我们在1985—1989年开展了丘陵旱地小麦耗水规律及看墒栽培技术研究。
In western Henan, about 7 million mu of wheat are planted year on year, accounting for about 10% of the province’s wheat field area, most of which are hilly dryland wheat. Due to the drought in the region over the past ten years, the yield of wheat is low and unstable. One of the province’s low-yielding wheat. The level of wheat yield and climate conditions are very closely related. According to the analysis of the relationship between the actual output of wheat and climate in the past 37 years from 1950 to 1986 in Luoyang, it shows that in the worst climate year, the wheat yield reduction rate reached 54.6% (1961), the best climate year and the wheat yield increase rate was 39.9 % (1956). In 37 years, there were 14 in a year where wheat production was more than 5% due to poor weather, and 12 in more climatically-suitable crops with a 5% or more increase in wheat. Thus, the climatic conditions of different years have a great impact on wheat yield. To this end, we carried out in 1985-1989 the law of wheat water consumption in hilly dry land and see moisture cultivation techniques.
