摘要

摘要:以濮阳市39年气象资料中的温、水、光为分析依据,分析了气象条件对濮阳市玉米生产的正负影响 。认为气象条件对当地玉米生产的有利影响为:① 5月25日—9月9日≥10℃活动积温在2700℃.日以上,满足早、中、晚熟玉米品种的需要。② 6月中下旬日平均日照时数为8小时,是全年日平均日照时数最多的时段,对玉米幼苗生长有利。③ 灌浆期降水量大,满足于物质积累所需水分。气象条件对玉米生产的不利影响为:① 麦收前后多晴热天气,出现干旱少雨的年份较多,给夏玉米播种带来一定困难。② 拔节到抽穗容易形成“卡脖旱”。③ 玉米拔节到开花期光照强度和日照时数不足,易造成授粉不良,果穗秃尖。

Abstract

Abstract: Take the Puyang city 39 year meteorological data in warm, the water, the light as the analysis bases, has analyzed the meteorological condition to the Puyang city corn production positive and negative influence. Thought the meteorological condition to the local corn production advantageous influence is: ①On May 25 - on September 9 ≥10℃ the active accumulated temperature above 2700℃. the date, meets early, the late-maturing corn variety needs. ②Mid-June daily average sunshine hour is 8 hours, is whole year daily average sunshine hour most time intervals, is advantageous to the corn seedling growth.③The grouting time precipitation is big, satisfies accumulates in the material needs the moisture content. The meteorological condition to the corn production adverse effect is: ①Around the wheat harvest is clear the hot weather, appears arid few rain the year to be many, brings certain difficulty for summer corn sowing seeds.②Joints the earing easily to form “the drought just when the ears of corn are about to come out”.③The corn joints the florescence strength of illumination and the sunshine hour is insufficient, easy to create the pollination not to be good, cob bare point.
