Outline
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 controlled by genetic factors of the variety, but also influenced by cultivation modes and ecological conditions. Under different ecological conditions, the high-quality cultivation mode of weak gluten wheat was based on a basic seedling of 2.40×106plants·hm-2, pure nitrogen of 180 kg·hm-2, and phosphorus 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. Under 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 requirements of high-quality weak gluten. The high-yield cultivation mode was based on a basic seedling rate of 1.80×106plants·hm-2, with pure nitrogen of 240 kg·hm-2. Phosphorus and potassium fertilizers 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.
