我国城镇、道路、工矿、企事业的拓展,使原有的菜地外移缩小。当前我国已成为蔬菜生产的大国,蔬菜生产是创汇、平衡外贸和农业、农村、农民致富的手段。在产业结构的调整中常压粮扩菜,侵占粮田,后果堪忧。提出了蔬菜栽培内部的间套轮作技术,移植拓宽到蔬菜与多种农作物的间套轮作上去,即蔬菜与粮、油、花、林、果、桑、畜、禽、鱼等相互间套轮作,可以大幅度地提高土地的复种指数,稳定粮田。它既可以生产多种农作物,又可增加蔬菜的品种、产量、产值,满足国内外对蔬菜的需求。该项措施如能广泛地应用于农业生产中,则具有重要的战略意义和经济价值。
China’s cities and towns, roads, industrial and mining, enterprises and the expansion of the original vegetable outreach. At present, our country has become a big country in vegetable production. Vegetable production is a means of foreign exchange earning foreign exchange and balancing the foreign trade with agriculture, rural areas and peasants. Atmospheric pressure in the adjustment of industrial structure expands the food, invades the grain field, the consequence is worrisome. The paper puts forward the intercrop rotation technique in vegetable cultivation. The transplantation extends to the intercrop rotation between vegetables and various crops, that is, the rotation between vegetables and grain, oil, flowers, forest, fruit, mulberry, livestock, poultry and fish , Can greatly raise the index of multiple crop land and stabilize the grain crop. It can produce a variety of crops, but also increase the variety of vegetables, production, output value, to meet the domestic and international demand for vegetables. This measure, if widely used in agricultural production, has important strategic and economic value.
