在小麦生育期间,选择一个经济高效的最佳补水期进行补水,以便夺取小麦高产。我们在进行区划工作中,发现小麦确实存在一个经济高效的最佳补水期,特提出供参考。据统计资料,睢县、杞县、通许、尉氏、鹿邑、太康、扶沟、西华、鄢陵、许昌、长葛、郾城、临颖、襄县、郏县,1966年小麦单产54～118.5公斤,15个县平均83.7公斤,而1950—1965年16年中各县单产为43.5～60.5公斤,15县平均52.5公斤。1966年各县小麦较前16年平均每亩增产10.5～58公斤,
During wheat growth, choose a cost-effective optimal replenishment period to replenish water in order to capture high yields of wheat. During the zoning exercise, we found that there is indeed a cost-effective optimal water-supplementing period for wheat, especially for reference. According to the statistics, the yields of wheat in 1966 in Lixian, Qixian, Tongxu, Weishi, Luyi, Taikang, Fugou, Xihua, Yanling, Xuchang, Changge, Gaocheng, Linying, Xiangxian and Juxian 54 to 118.5 kilograms, an average of 83.7 kilograms in 15 counties, and from 1950 to 1965, the yield of each county was 43.5 to 60.5 kilograms and that of 15 counties was 52.5 kilograms. In 1966, the average output of wheat in each county increased 10.5 to 58 kilograms per mu compared with the previous 16 years,
