夏玉米侧深种肥同播技术

播种是夏玉米生产的最关键技术环节，种肥同播技术一次作业完成多项任务，近年来得到推广应用。该项技术在应用过程中存在着肥害烧苗，增产效果达不到预期等问题。为解决诸类问题，提出了侧深玉米种肥同播技术。侧就是侧施肥，实现种肥分离，解决肥害烧苗问题。同时，5厘米的种肥距离是保证肥料就近供应的理想位置，达到防肥害、增肥效的优化布置。深的要求是深施肥，垂直方向上，肥料比种子要深5厘米以上。肥料就施在地表下8-10厘米的位置。满足玉米生长发育需求，随着养分溶解下渗，诱导根系向深层发育，促根壮秆。侧深种肥同播技术的关键就是选好品种，用好种子，以测深施肥为抓手，测土配方，单粒精播，提高播种质量，通过有害生物绿色防控，精细管理，实现肥效利用率高，产量高，品质好，收益高。

Summer Corn Simultaneous Sowing Technology of Fertilizer and Seed with the Side and Deep

Sowing is the most critical technical link in summer corn culture. The simultaneous sowing of seed and fertilizer can accomplish many tasks in one operation, and has been applied in recent years. There are some problems in the application of this technology, such as fertilizer damage to seedling, unexpected yield lost. In order to solve these problems, the side and deep fertilizer with seed simultaneous sowing method was put forward. Side is to separate the seed and the fertilizer, to avoid the fertilizer damages the seed. At the same time, the 5cm distance between the fertilizer and the seed is the ideal location to ensure the suitable supply of the fertilizer. Deep is sowing fertilizer deeper 5cm more than the seed, so that fertilizer is applied just 8-10cm below the soil surface. It can meet the needs of maize growth and development, and make the roots deeper and strong, at the same time to strengthen the stalk. The key of the side and deep simultaneous sowing technology if fertilizer and seed is to select good varieties, use high quality seeds, use side and deep fertilizing as the effective means, soil test to determine fertilizer, single precision seed sowing, ensure high sowing quality, pest weed and disease control, fine management, make sure to achieve high yield, high quality, high income.
