0.72倍;三是冬季比种油菜经济效益高的作物,如马铃薯比油菜增收3.57倍,大蒜增收3.75倍,蚕豆增收1.2倍,豌豆增收3倍,小麦增收0.77倍。因此,1985年春在286亩水田中种上了经济作物,比1983年50亩增长34.72倍;比1984年增长91％。如1983年西瓜面积为20亩,每户平均不到5厘,1985年发展到124亩,增长了5.3倍。1985年经济作物总收入153,512元,比1983年增长3.9倍,比1984年增长1.1倍,作物种类由5种增至16种,迈出了品种多样化的步伐。 三、引进新品种,应用新技术 1、引进良种 四年来,早稻两次更换品种。1983、1984年引进二九五、竹系26取代先锋1号、二九南。1985年引进浙辐802、二九丰、73～07取代广六矮四号、竹系26。小麦引进浙麦2号、扬麦4号取代908。花生引
0.72 times. Thirdly, crops with high economic returns in winter such as potato increased by 3.57 times than canola, garlic increased by 3.75 times, broad bean increased by 1.2 times, pea increased by 3 times and wheat increased by 0.77 times.

The number of crops increased from 5 to 16, and diversified varieties were taken. Third, the introduction of new varieties, the application of new technologies 1, the introduction of seed four years, two varieties of early rice. In 1983, 1984 introduced 295, 26 bamboo replaced Pioneer 1, 29 South. In 1985 the introduction of Zhejiang spokes 802, two nine abundance, 73 to 07 to replace Guang Liu dwarf four, bamboo 26.
