正阳县农场地处豫南,气候温和,雨量充沛,地势平坦,土地肥沃。全场粮食作物面积8400亩,每个农工负担耕地近40亩,是我省机械化程度较高的农场之一。从1985年开始农业经营,由原来的商品粮生产,逐渐转变为商品种子生产,目前种子生产已初具规模。现已发展成为我省南部较大的商品种子基地之一。我场在开展商品种子生产中,为了提高产量,保证优良品种的质量,从1980年开始推广化学除草新技术,至1984年在小麦、大豆等主要作物田全面实行了化学除草,取得了良好效果。化学除草与人工除
Zhengyang County farm is located in southern Henan, a mild climate, abundant rainfall, flat terrain, fertile land. The audience covers an area of 8,400 mu of grain crops and each agricultural laborer pays nearly 40 mu of cultivated land, one of the most mechanized farms in our province. Since 1985, agricultural management has gradually shifted from commodity grain production to commodity seed production. At present, seed production has begun to take shape. Has now developed into the southern province of one of the larger commodity seed base. In the field of commodity seed production, in order to increase the yield and ensure the quality of fine varieties, we started to promote the new chemical weeding technology in 1980. By 1984, we implemented chemical weed control in major crop fields such as wheat and soybean and achieved good results . Chemical weeding and artificial addition
