大豆产量除与品种有直接的关系外，与密度、种植形式、施肥、田间管理等诸多因素也有密切关系。笔者在大豆常规栽培技术的前提下，于１９９７年进行了大豆超稀植高产栽培试验，旨在通过稀植达到大豆产量突破。一、试验过程试验地设在所内试验地，面积为１．８亩。土壤为沙... In addition to the soybean yield has a direct relationship with the species, and density, planting forms, fertilization, field management and many other factors are also closely related. Under the premise of conventional soybean cultivation techniques, the author conducted a trial of ultra-thin planting and high-yielding cultivation of soybean in 1997, aiming to achieve a breakthrough in soybean yield through sparse planting. First, the test process The experimental ground in the test site, an area of ​​1.8 acres. Soil is sand ...
