我場位于黄河故道堤南脚下,全部耕地原来都是低洼易涝的碱荒。从1956年建場起,每年都种植了一定数量的棉花,历年来棉花产量直綫上升,比附近人民公社优質高产。我場棉花年年丰产的原因是多方面的,而改碱保苗則是其中的一个重要經驗。对改碱保苗采取了以下的几种措施。一、整地保墒,防碱保苗:每年于封冻前,将全部棉田翻耕九寸至一尺二寸,光耕不耙,让其冻垡,使土表盐分随冬季雨雪向下渗透,減輕表层含盐量。在早春提早耙地六到八遍保墒,防止盐碱随土壤水分
My field is located at the foot of the Yellow River's old course, all cultivated land was originally a low-lying flood-prone alkali shortage. Since its establishment in 1956, a certain amount of cotton has been planted every year. Over the years, cotton output has risen linearly and is superior to the nearby people's commune. There are many reasons for the high yield of cotton in my field every year, and one of the important experiences is to change alkali and seedlings. Alkali seedlings to take the following measures. First, the preparation of soil moisture, anti-alkali seedlings: Each year before freezing, the entire cotton fields nine inches to one foot two inches inch, light rake, let it freeze, so that the soil surface salt with winter rain down snow infiltration, reduce Surface salt content. Rake early in early spring to harrow six to eight times soil conservation, to prevent salt and alkali with soil moisture
