Fertilization Technology of Strong Gluten Wheat in Sand, Sandy Loam Soil for Good Quality and High Yield
摘要
Abstract
In order to produce strong gluten wheat of which quality meet the national standard in Yudong sand and sandy loam ecological zones, under the current production, ecological and technological conditions, the field experiment was conducted. In the condition of equal nitrogen, two nitrogen fertilizers in the jointing stage and booting stage resulted in production increase of 23. 2% compared to CK. In the sand land,a heavy urea dressing of 225 kg/ha in the jointing stage made grain crude protein content increase by 2. 55 percentage points, with a relative increase of 22. 3%粀et gluten content increase by 5. 2 percentage points,with a relative increase of 21. 5%, dough stability time increase by 11. 2 min,and the softening degree reduce from 61 to 12. If the period of nitrogen application was retarded appropriately, the protein, wet gluten content and dough stability time continued to increase and the softening degree got lower. The test results showed that nitrogen topdressing in the middle and late period was the key measure to improve the yield and quality of strong gluten wheat in sand soil. In addition,application of the new excellent agent could improve the quality of strong gluten wheat in sand and sandy loam soil,especially could extend the dough stability time.关键词
