早茬麦一般在10月下旬播种,这时气温高,土壤供肥能力强,出苗和冬前分蘖的条件均比晚茬麦优越,有利于丰产。1967年,我们在徐行公社调查早茬麦与晚茬麦的产量结构,也证实了这一点。测产结果,早茬麦亩产847.2斤,比晚茬麦增产90斤。(表一) 表1.早晚茬麦产量结构比较(品种;扬麦一号) 据研究,在水分适宜的情况下,小麦从 Early crop of wheat is generally planted in late October, when the temperature is high, soil fertility, emergence and pre-winter tiller conditions are superior to late crop wheat, is conducive to high yield. In 1967, we investigated the yield structure of early wheat and late wheat in Xuhang Commune. This is also confirmed. Measured results, stubble early yield of 847.2 kg of wheat, wheat yield than late crop of 90 pounds. (Table 1) Table 1. Early and late crop yield structure comparison (variety; Yangmai No. 1) According to the study, in the case of water suitable, wheat from
