农—牧—渔业系统即农牧渔业综合发展的路子,其重要性在于把农、牧、渔三者有机结合起来,充分利用资源,形成良性循环的耕作制度。江西地处中亚热带地区,气候雨量都宜发展一年多熟,粮食与多种经营综合发展,有利于实现农牧渔业系统。本文分三部分:一、发展多熟高产是江西农业增产的主要途径,介绍自然条件,作物主要复种方式,多熟制的优越性和作用。1984年比1949年耕地仅增0.7%,而粮食增加3倍,经济作物、生猪各增5倍,牛增57%,人口增1.6倍。是什么创造了奇迹?关键是发展多熟制与提高单产同时并举、双季稻面积增加4倍和单产提高1.5倍具有战略意义。一年多熟可充分利用土地和光能,是稳产的保证和高产的基础,世界人口激增,形势将迫使人们采取一切方法发展多熟制,尽量增产粮食。二、农牧结合,介绍结合的必要性、途径和优点。粮多—畜牧多—肥多—粮多,已形成良性循环。江西有丰富的农副产品和四千多万亩草山草坡,是发展畜牧的优越条件,同时又是转化粮食增收创汇的出路,结合则两利,不结合则两败。三、农渔结合,江西水面占土地面积10%,水田占耕地85%,是发展渔业的有利条件,稻田养鱼是充分利用前所未用的资源,具有投资少、见效快、效益高的优点,技术掌握好,矛盾处理得当便能鱼稻双丰收。
The importance of the comprehensive development of agriculture, animal husbandry and fishery system, that is, farming, animal husbandry and fishery lies in the organic combination of agriculture, animal husbandry and fishery, making full use of resources and forming a virtuous circle farming system. Jiangxi is located in the subtropical region, climate and rainfall should be developed more than a year, comprehensive development of food and a variety of management, is conducive to the realization of farming, animal husbandry and fishery systems. This article is divided into three parts: First, the development of multi-cropping high yield is the main way of agricultural production in Jiangxi Province, introducing the natural conditions, the main cropping methods, the superiority and role of multi-cooked. In 1984, the cultivated area only increased by 0.7% compared with 1949, while grain increased three times. Economic crops and live pigs increased by 5 times each, cattle increased by 57% and population increased by 1.6 times. What has created a miracle? The key is to develop multi-cooked and raise both yields simultaneously, double crop area doubled and doubled 1.5-fold higher yield is of strategic importance. The fact that more than one year of ripening can make full use of land and light energy is the basis for ensuring a stable yield and high yield. With the world population surging, the situation will force people to adopt all methods to develop multi-cropping systems and try their best to increase grain output. Second, the combination of agriculture and animal husbandry, the introduction of the combination of necessity, ways and advantages. Food and more - Livestock more - more fat - more food, has formed a virtuous circle. Jiangxi is rich in agricultural and sideline products and more than 40 million mu of grassy hills and grass slopes are excellent conditions for the development of livestock husbandry. At the same time, it is also a way out of converting grain to foreign exchange earnings. If we combine both, we will lose both. Third, the combination of agriculture and fishery, Jiangxi Province, 10% of the land area of ?? land, paddy fields account for 85% of arable land, is the favorable conditions for the development of fisheries, rice farming is to make full use of resources that have never been used, with less investment, quick, high efficiency Advantages, good technical mastery, contradiction can be handled properly double harvest of fish and rice.
