摘要
该文探讨了驻马店市小麦生长季干旱特点,降雨量和土壤渗透深度的关系,小麦各生育阶段对人工增雨的精细化需求指标。结果表明:驻西部、西北部干旱较重,东部、东南部干旱较轻。以春季干旱最重,秋季次之,冬季最轻。1mm的降水量平均土壤渗透深透对应为0.76cm。沙土的透水性最强,壤土次之,粘土最差。一次积雪过程,待积雪完全融化后,1mm的降雪对应的土壤渗透深度为1cm。播种期:9月10日至10月10日期间,适宜人工增雨量不少于60mm或10月1—10日增雨量不少于30mm,累计适宜增雨量为60~80mm;越冬至返青期:单次人工增雨量为30 mm或累计增雨量不超过80mm,增雪过程,在当前的气候条件下,不设上限;拔节至抽穗期:单次降水量不能大于50mm或累计降水量在80~100mm;灌浆期:5月5日前或5月5日后只要出现过30mm的降水过程,则不建议人工增雨。累计降水量少于30mm,则就需要人工增雨,适宜增雨量30~50mm。
In this paper,the relationship between the drought characteristics of wheat growth season and the depth ofsoil infiltration in the wheat growing season in the city of zhumadian was discussed. The results show that the droughtin the western and northwestern areas is heavier,and the eastern and southeastern parts are less arid. The springdrought is the heaviest,the fall is the second and the winter is the lightest. The average soil penetration of 1 mm was0.76 cm. Sandy soil is the most permeable,the loam of loam,the worst clay. Once the snow is completely melted,thesoil penetration depth of 1 mm is 1 cm. Planting period：during the period from September 10 th to October 10 th,it issuitable for artificially increasing rainfall not less than 60 mm or October 1—10. The rainfall is not less than 30 mm,and the accumulated rainfall is 60~80 mm. During the winter and Qing period：single artificial rainfall increase of30 mm or cumulative rainfall not exceeding 80 mm,increasing snow process,under current climate conditions,no up-per limit;The single precipitation cannot be greater than 50 mm or accumulative precipitation of 80~100 mm. Grout-ing period：after May 5 or May 5,the precipitation process of 30 mm is not recommended. The accumulated precipita-tion is less than 30 mm,then it needs artificial precipitation,suitable for increasing rainfall 30~50 mm.
