【摘要】 笔者于１９９１～１９９３年，在罗甸县兴隆基点进行了改稻田复种一季早熟蔬菜为连作复种两季蔬菜的试验。试验结果表明：１９９２年最佳蔬菜组合的亩产值、亩净产值分别比对照增长５２．１７％、８５．１６％；１９９３年最佳蔬菜组合的亩产值、亩净产值分别比对照增长４３．８５％、４８．１５％。提高了土地利用率和产出率，减轻病虫和杂草危害，为建立稻田复种轮作制作出了示范。更多还原

【Abstract】 The experiment was conducted at Luodian experimental site from 1991─1993,in which different cropping patterns with vegetable were compared for paddy,The experimental result indicated that the output value and net output value of the optimum combination of vegetables increased by 52.17%and 55.16%than that of control 1n 1992,and by 43.85%and 43.15%in 1993.It increased utilization rate and producti-vity of land.This optimum treatment also showed low damage of disease and insect pest as well as weed,therefore it was proved to be a valuable cropping pattern in paddy field to the local areas.更多还原
