“麦收胎里富,种好是基础。”这就是说,在播种时就要为实现“既要保证一定的每亩穗数,又要获得大穗大粒”打下基础。在播种这个环节上,我们着重处理好四个关系。一、土壤与根系小麦是一种深根作物,特别是密植高产时,根量增多,更需要加深耕层。浅耕则土壤板结,透气不良,根系不下扎,不但不能培育壮苗,而且会造成头重脚轻根底浅,遇大风雨就倒伏。群众说:“土地不深翻,麦根无处钻”。同时,高产的小麦需要较多的底肥,如果浅耕,松土层薄,施肥量大,就会因肥料过于集中而影响麦根深扎,甚至使麦苗枯黄死,造成减产。所以,壮苗需要壮根,壮根必须深耕。在整地上,我们采取了“三犁九耙、 “Wheat is rich in seeds and good seeds are the foundation.” This means laying a foundation for “achieving a certain amount of spikes per acre while obtaining large ears and large grains” at the time of sowing. In sowing this aspect, we focus on handling the four relationships. First, the soil and roots Wheat is a deep-rooted crop, especially close planting high yield, the root volume increased, but also need to deepen the topsoil. Shallow tillage soil compaction, poor ventilation, root no less than bar, not only can not cultivate strong seedlings, but also will cause top-heavy shallow, heavy wind and rain lodging. The masses said: “The land is not deep, McGan nowhere to drill.” At the same time, high-yield wheat needs more base fertilizer, if shallow tillage, loose soil thin, large amount of fertilizer, fertilizer will be too focused on the impact of wheat root deep bar, or even wheat seedlings dead yellow, resulting in reduced production. Therefore, strong seedlings need strong roots, strong roots must be plowed. In the preparation of land, we adopted the "Sanli Ji rake,
