我们大队在绥化县西郊,有耕地6,961亩,主要种植蔬菜,其中马铃薯种植面积2,100亩左右,约占总播种面积的30%。每年向国家交售马铃薯600余万斤,其中种薯占20%。无产阶级文化大革命以来,我们积极开展群众性科学实验活动,在马铃薯生产上采用“株系选,整薯播,夏播留”综合保种措施,有效地防止了种性退化,使单位面积产量迅速提高。从1966年起,连续十年不从北部调种,亩产由1,000多斤提高到3,000多斤,比文化大革命前的1965年增加近1倍。同时,第一生产队还创造了小面积亩产8,267斤的高产纪录。夏播留种,提高种性
Our brigade has 6,961 mu of arable land in the western suburbs of Suihua County. It mainly grows vegetables, including about 2,100 mu of potato plantation area, accounting for about 30% of the total planted area. Every year to sell more than 600 kilograms of potatoes, of which 20% of seed potatoes. Since the Great Proletarian Cultural Revolution, we have actively carried out mass scientific experiments and implemented integrated seed conservation measures such as “selecting plants from the whole strains of potatoes and sowing them in summer,” effectively preventing the degeneration of species and making the output per unit area Rapid increase. From 1966 onwards, no planting was carried out from the north for 10 consecutive years. The yield per mu was raised from 1,000 to 3,000 kilos, nearly double that of 1965 before the Cultural Revolution. At the same time, the first production team also created a record high yield of 8,267 pounds per mu. Summer sowing to increase species
