华北地区,经常春早,大部分棉花种在旱地(如河北省棉田的四分之三是旱地),因此播种前的保墒工作,是旱地耕作的重要技术措施。但在保墒技术执行方面,还存在着一些问题。如武安伯延村1953年的7.868亩棉田中,由于保墒不良,播种前下等墒棉田(麦层干土厚度在4.5—6.0厘米)占49.3%加上播种技术不好,出苗很差,以后毁掉重种的达五千多亩。根据1953年在河北南宫、成安、武安等地的调查,在整地保墒方面,主要应掌握以下两个环节:
In North China, most of the cotton is often planted in dry land in early spring (for example, three-fourths of the dry land in cotton fields in Hebei Province). Therefore, soil moisture conservation before sowing is an important technical measure for dry farming. However, there are still some problems in the implementation of moisture conservation technology. For instance, in the area of 7.868 mu of cotton fields in Buyan village of Wu’an County in 1953, 49.3% of the soil moisture before sowing (the thickness of dry soil of wheat layers was 4.5-6.0 cm) was poor due to poor soil moisture, poor planting techniques and poor emergence. Destroyed more than 5000 acres of heavy. According to a survey conducted in 1953 in Nangong, Cheng’an and Wuan in Hebei, the following two links should be mastered in soil preparation and soil conservation:
