一、浇冻水的增产作用。1976、1978和1981年,我区5个县17个单位浇冻水的试验表明:浇比不浇(对照)的普遍表现增产。三年资料统计:浇冻水的平均亩产483.3斤,不浇冻水的411.3斤。浇比不浇的平均每亩多收72斤,增产17.5%。增产的主要原因是亩穗数的增加。据其中三个单位的资料:浇冻水的每亩成穗36.3万,未浇的成穗31.3万,浇比不浇的增加5万穗。
First, pour cold water stimulation effect. In 1976, 1978 and 1981, 17 units of 5 counties in our district were drenched with water to show that the general performance of irrigating (control) increased. Statistics for three years: The average yield per mu of cold water is 483.3 kg, 411.3 kg without pouring cold water. Pouring than the average irrigated more than 72 pounds per mu, an increase of 17.5%. The main reason for the increase is the increase in the number of ears per mu. According to the data of three units: 363,000 per mu of water poured into frozen water, 313,000 into unwashed ear, and 50000 spike of water added without pouring.
