一、改革种植措施,实行“八改八增” 1.改串种穴播为足墒开沟抢时直播,增施基肥,奠定高产基础。以往在麦收前10天串种母本107,不仅共生期长造成苗弱苗瘦,而且收麦时机械损伤苗子,易造成缺苗断垄。为此,实行麦收后及时造足墒情,施足基肥,亩施入有机肥2500公斤,磷肥30～40公斤,氮肥(折纯氮)10公斤,与土壤充分混和开沟抢时直播。 2.改白种下地为富胎播种,增施种肥,保苗全苗壮。夏播配制杂交玉米种,由于玉米自交系具有生长势弱、抗逆性差,单株生产力低,生长发育进程较快等特点,播种时改以往白种下地为增施种肥磷酸二铵3公斤,优质农家肥200公斤,搞好幼苗环境,确保苗全苗壮。
First, the reform of planting measures, the implementation of “Eight changes eight by” 1. To change the series of seed sowing for moisture ditch grab live broadcast, increase base fertilizer, laying a high yield basis. In the past in the first 10 days of wheat harvesting female parent 107, not only symbiotic period caused by weak seedling thin, and mechanical damage when harvesting wheat seedlings, easy to cause lack of seedlings broken ridge. To this end, the implementation of the wheat harvest in a timely manner to create enough moisture, Shizujifei, Mushi 2,500 kilograms of organic fertilizer, phosphate fertilizer 30 to 40 kilograms, nitrogen fertilizer (pure nitrogen) 10 kg, fully mixed with the soil to broadcast live and broadcast. 2. Change to the white seed for planting rich seeds, increasing fertilizer, seedling seedlings Zhuang strong. Summer maize hybrid maize hybrids, maize inbred lines due to the growth of weak, poor resistance, low productivity per plant, rapid growth and development and other characteristics of the sowing to change the past under the white seed dressing fertilizer DAP 3 Kg, 200 kg high-quality farm fertilizer, improve seedling environment, to ensure that the whole seedlings Miao Zhuang.
