Abstract:

In order to select a reasonable fertilization pattern suitable for high-yielding and high-quality production of rice stubble weakly glutenous wheat,this experiment was conducted with weakly glutenous wheat Ningmai 13 and Wanximai 0638 as the test varieties,with no fertilization(CK),conventional fertilization of compound fertilizer+urea(T1),slow-release blended fertilizer(T2),loss-control fertilizer(T3),humic acid compound fertilizer(T4),and wheat formula fertilizer(T5),under the same conditions of nutrient supply,the effects on dry matter distribution and transport,filling,yield and quality of weakly glutenous wheat were analyzed.The results showed that slow-release blended fertilizer and wheat formula significantly increased the post-flowering dry matter production,and increased wheat grain filling rate,effective filling days,and grain weight compared with conventional fertilizer application.The grain yield increased by 9.27%—24.30% and 11.64%—22.98% respectively compared with conventional fertilizer.Slow-release blended fertilizer 2 years two varieties than conventional fertilization treatment of nitrogen fertilizer agronomic efficiency increased by an average of 23.14%, 36.88%, wheat formula fertilizer two years two varieties than conventional fertilization increased by an average of 36.31%, 39.35%. Wheat formula fertilizer treatment of two wheat varieties for testing grain quality had reached the national standard of weak gluten wheat. In summary,wheat formula fertilizer can be used as one of the fertilization patterns for high-yielding and high-quality production of rice stubble weak-gluten wheat in the test area,or appropriately reduce the application amount of slow-release blended fertilizer as the fertilization pattern for high-yielding and high-quality production of rice stubble weak-gluten wheat.
