近年来,科研人员对多个小麦品种的灌浆速度进行了研究,发现在小麦蜡熟末期千粒重为最大值。之后3天开始收获,每千粒重平均每天减少0.3-0.4克,而到第4-5天开始收获,每千粒重平均每天减少1-1.2克。若每亩按35万-40万穗、每穗35粒计算,千粒重每降低1克,每亩减产13-15公斤。研究表
In recent years, researchers have studied the grain filling rate of several wheat cultivars and found that the 1000-grain weight is the maximum at the ripening stage of wheat wax. After three days, the harvest started, decreasing by 0.3-0.4 g / day on average, while harvesting started on days 4-5, decreasing by 1-1.2 g / day on average. If 350,000-40,000 spikes per acre, 35 grains per spike, 1000 grams per weight reduction of 1 grams per acre cut 13-15 kg. Study Table
