【摘要】 1979—1983年在所内和克山县北联公社万亩以上的面积上进行了大豆生产开发性试验。在土壤有机质不低于4％的丘陵漫岗黑土地上,选用比当地无霜期早熟5—7天的优良品种,每亩保苗2.3—2.6万株。行距45—50厘米的“早、窄、密”为主体的综合高产栽培法。经受了严重干旱和低温寡照等自然灾害不同的年份考验,连续获得了亩产超三百斤的产量,为黑龙江省克拜丘陵黑土区大豆大面积创高产、稳产开辟了新的途径。更多还原

【Abstract】 The experiment had been conducted in Keshan Agricultural Research Institute and the ten-thousand mu soybean experimental base which located in the Beilian People’s Commune, Keshan County from 1979 to 1983. The experimental feild is on hilly land. The black soil in the experimental feild contains more than 4% organic matter The soybean cultivar used in the experiment was high-yield and 5-7 days earlier mature before local frost-free period. The full stand of seedlings kept in a hectare was 350-400 thousand. The row spacing was 45-50cm, Above mentioned technique is the main point of the complex high-yielding cultivation method named "early, narrow and close". Standing up to severe drought, low temperature, insufficient illumination and other nature calamities, the yield was continuouslly over 300 jin per mu. This technique opened up a new way to high and stable yield of soybeans in large area of hilly black soils in Keshan-Baiquen region of Helongjiang Province.更多还原
