夏大豆生长期间,历经气候变化剧烈的夏季,其生长发育常常会受到干旱、渍、涝、冰雹等灾害的影响而不能稳产高产。采用如下技术,在减轻各种不利条件影响的同时,又能取得增产效果,值得推广应用。一、育苗移栽育苗移栽可使大豆提早成熟10～15天,采用此技术可种植生育期较长的品种。通常在麦收前15天进行育苗。收麦后及时移栽。该技术在大豆适播期出现连续干旱或阴雨不能适时播种时应用效果尤为显著。二、稀植稀植能充分发挥大豆根、茎发达的
Summer soybean growth, after a sharp summer climate change, its growth and development will often be drought, stains, waterlogging, hail and other disasters can not be stable yield and high yield. The use of the following technologies, while mitigating the impact of various adverse conditions, but also to achieve increased production efficiency, it is worth promoting. First, seedling transplanting Seedling transplanting can make soybean mature 10 to 15 days earlier, using this technology can grow longer varieties. Seedlings are usually harvested 15 days before harvest. Receive timely transplanting wheat after transplanting. The technology is particularly effective in the sowing sowing period of continuous drought or rainy days can not be timely sowing effect is particularly significant. Second, dilute sparse planting can give full play to soybean root, stem developed
