河南省临颖县土壤80％以上是黄土(粉砂壤土)与黑土(粘壤土)。黄土地区小麦的前作以晚粟为最多,黑土地区以晒旱地为最多,因此,确定以这二类小麦地为调查和总结整地保墒经验的重点对象,并兼顾到二合土(粉砂粘壤土)以及其他茬子地的整地保墒经验的总结工作,兹将调查结果分述如下: 黄土、两合土。黑土早茬地与晚茬地的整地保墒关键 (一)1953年秋季奇旱,自8月20日到10月29日相隔二个月零九天未降雨,是十年来未见过的旱象。临颖县小麦播种面积的35％由於土壤水份不足,种不下麦子,经政府号召浇水抢播。未浇水播种的小麦地,一般缺苗率达16％左右。据本组检查分析结果,缺苗的主要原因是土壤保墒不良
More than 80% of the soil in Linying County of Henan Province is loess (silty loam soil) and black soil (loam loam). In the loess area, the amount of evening millet was the highest in the pre-crop and the dry-land was the most in the black soil area. Therefore, the two types of wheat land were selected as the key objects to investigate and summarize the experience of soil- ) And other stubble ground preparation for soil moisture conservation experience, we will survey results are as follows: Loess, two combined soil. The Key to Soil Preparation and Preservation of Premature Cropland and Late Cropland in Black Soil (I) Unusual autumn in 1953, with no rainfall after two months and nine days from August 20 to October 29, is a drought phenomenon that has not been seen in a decade. Linying County, 35% of the area planted with wheat due to lack of soil moisture, planted wheat, the government called for watering broadcast. Not watered sown wheat, the general lack of seedlings rate of about 16%. According to the inspection results of this group, the main reason for the lack of seedlings is that soil moisture is poor
