唐山属于北方冬麦区,这一地区的小麦在越冬期间,由于气候条件及栽培方面的种种原因,容易发生冻害死苗现象,从而造成减产。加强越冬管理,保苗安全越冬,是夺取小麦增产丰收的重要一环。如何做好越冬管理,其措施是以浇好冻水为主要环节,其次补施冬肥,铺沙盖土,防止小牲口哄啃麦苗等措施。那么,怎样浇好冻水呢?据我们多年的实践经验,要注意以下几点:一、浇冻水要适时。过早,蓄墒防冻效果差;冻水浇的过晚,容易地表结冰,使麦苗窒息死亡,那么何时为好呢?应掌握在日消夜冻的时段浇冻水为好,就是在“小雪”前后进行。二、对麦苗要分类指导,不要千篇一律。对 Tangshan belongs to the northern winter wheat area, wheat in the region during the winter, due to climatic conditions and cultivation of various reasons, prone to frostbite dead phenomenon, resulting in reduced production. Strengthening winter management, ensuring seedling safety and winter, is an important part to seize the yield increase of wheat. How to do a good job of winter management, the measure is to pour frozen water as the main link, followed by make-up winter fertilizer, sand cover soil, to prevent small animals coax nibble and other measures. So, how to pour frozen water? According to our many years of practical experience, we should note the following: First, pour frozen water to timely. Premature storage of moisture antifreeze effect is poor; frozen water pouring too late, easy surface freezing, wheat seedlings suffocate death, then when is it good? “Little snow” before and after. Second, to classify wheat seed guide, not stereotyped. Correct
