遵化市地处冀东北地区,属于冬小麦种植北部边缘带,秋、春气温较低、越冬期长,返青晚、穗分化时间短,不易形成大穗,严重制约产量水平的提高。近年来,我市在不断提高小麦播种质量、越冬期管理的基础上,狠抓春季管理,形成了一整套针对不同麦田的管理技术,显著提高了小麦单产水平。其技术要点如下:一、中耕锄划中耕锄划可以起到提高地温、促苗早发、保持土壤墒情、促使根系生长和消灭杂草。一般麦田应以浅锄细划为主,对有旺长趋势的麦田锄划
Zunhua City is located in the northeast of Hebei Province, belonging to the northern margin of winter wheat planting, autumn and spring temperature is low, long winter, returning late, spike differentiation is short, not easy to form big spike, seriously restricting the level of yield increase. In recent years, the city continues to improve the quality of wheat seeding, wintering management, pay close attention to spring management, formed a set of management techniques for different wheat fields, significantly increased the level of wheat yield. The technical points are as follows: First, cultivating hoe draw rowing hoe draw can play to improve ground temperature, promote seedling early hair, soil moisture to promote root growth and eliminate weeds. General wheat field should shallow shallow hoe thin plank, there is a long trend of wheat field hoe draw
