Effect of Cultivation Modeand Ecological Conditions on Grain Quality of Weak Gluten Wheat
To study the effects of different cultivation modes and ecological conditions on the grain quality of weak gluten wheat,8 Yangmai series and Ningmai series weak gluten wheat varieties and 2 medium gluten wheat varieties were used as materials to analyze the stability and differences of grain bulk weight,protein content,and starch content of weak gluten wheat under different cultivation modes and ecological conditions.The results showed that the quality of wheat grains is not only con-trolled by genetic factors of the variety,but also influenced by cultivation modes and ecological condi-tions.Under different ecological conditions,the high-quality cultivation mode of weak gluten wheat was based on a basic seedling of 2.40 × 106 plants·hm-2,pure nitrogen of 180 kg·hm-2,and phos-phorus and potassium fertilizers mainly based on basal and seedling fertilizer.The nitrogen fertilizer was based on basal fertilizer:seedling fertilizer:jointing fertilizer(before 3.5 leaves)=7∶1∶2.Un-der this cultivation mode,weak gluten wheat showed low protein content,good grain bulk weight,and high starch quality.Medium-gluten varieties Yangmai 25 and Yangmai 28 could also meet the re-quirements of high-quality weak gluten.The high-yield cultivation mode was based on a basic seedling rate of 1.80 × 106 plants·hm-2,with pure nitrogen of 240 kg·hm-2.Phosphorus and potassium fer-tilizers were mainly based on basal and seedling fertilizer,and nitrogen fertilizer was based on basal fertilizer:seedling fertilizer:jointing and booting fertilizer=5∶2∶3.The tested varieties showed high protein content in their grains under this cultivation mode,and most varieties can not meet the standards of weak gluten wheat.To ensure the quality of weak gluten wheat,suitable varieties should be selected,and the first cultivation mode should be adopted based on conventional field cultivation measures,and appropriate adjustments should be made according to the local climate and ecological conditions of the year.
