摘要
对半湿润区无水浇条件旱薄地冬小麦增产技术进行了研究。结果表明,土层厚0.6～1m 的旱薄地低产麦田,充分利用有限的土壤水分,冬小麦亩产量可由100kg 左右增至300kg 以上。采用包括迅速培肥地力的施肥技术,有效的蓄水保墒的耕作制度,建立高产低耗的群体结构,培肥壮苗的播种技术,以及利用抗旱品种等一套综合增产措施,可有效地改善早薄条件,提高水分的利用效率,获得大面积大幅度增产放果。
Studies on techniques for increasing yields of winter wheat in nonirrigated,dry and poor landin semi—moist areas were carried out with the following results:In the dry,poor and low—yield wheat land with the soil layer as thick as 0.6～1m,with the limited water in the soil being fully utilized,the grain yield of winter wheat per mu
could be increased from about 100 kg to 300 kg above.With a set of comprehensive measures of increasing yields being used,which included the fertilizer practices for enriching the soil rapidly,the cultivation system for effectively keeping the water in the soil,setting up the population structure for high yields but low consumption,The sowing
technique for developing strong seedlings and utilizing drought-resistant varities,the dry and poor characters could be effectively improved with the increase of water utilized efficiency and a great increase in yield in vast areas could be resulted.
