都昌县地处赣北鄱湖沿岸,全县共有旱地21万亩,其中红壤旱地14.6万亩,占旱地总面积的68.9％,是一个典型的丘陵红壤棉区。1981年亩产皮棉突破100斤关后,连续五年五大步,亩产皮棉增加到60.5公斤,总产皮棉5000吨,现将我县植棉经验总结如下: 一、改土治水,搞好棉田基本建设 我县棉地有80％属丘陵红壤,丘陵岗地灌水困难,要夺取棉花高产稳产,改土是基础,治水是保证。为了解决灌溉问题,全县13个集中产棉乡,从1979年开始,兴建了36.78千瓦以上的抽水站157座,近三年又机改电33座,增加灌溉面积5万余亩,使全县70％的棉地每年能灌溉水2～4次。为了改良红壤土,
Duchang County is located along the coast of Poyang Lake in northern Jiangxi Province. The county has a total area of 210,000 hectares of dry land, of which 136,000 mu of red paddy dry land, accounting for 68.9% of the total dry land area, is a typical hilly red soil cotton area. After the lint of lint broke through 100 pounds in 1981, it has made five major strides in five years in a row. The lint yield per mu has increased to 60.5 kg and the total output of lint cotton has reached 5,000 tons. Now, the experience of cotton planting in our county is summarized as follows: Capital construction 80% of cotton fields in our county belong to the hilly red soil. The irrigation in the hills and valleys is difficult. It is necessary to seize the high and stable cotton yield and soil improvement, and water control is the guarantee. In order to solve the problem of irrigation, the county has 13 centralized cotton-producing townships. Since 1979, 157 pumping stations with a capacity of 36.78 kilowatts have been constructed and 33 have been electrified by machines in the last three years, increasing the irrigated area by more than 50,000 mu, 70% of the county’s cotton can be irrigated 2 to 4 times a year. In order to improve red loam soil,
