针对吉林省中部松辽平原台地旱情日益加重 ,黑土区培肥问题日趋严峻 ,采用玉米宽窄行轮换种植、条带深松、留高茬耕作新技术。通过 3年对土壤理化性状的分析表明 ,该项技术可以有效地提高土壤蓄水能力 ,建立土壤水库 ,更重要的是可以增加秸秆还田量 2 0 % ,增加土壤有机质 ,培肥地力 ,增加产量。因此是当前推广旱作节水农业技术中有效的办法。
Due to the increasing drought in Songliao Plain in central Jilin Province, the problem of fertilizing in black soil area is becoming more and more serious. Through three years of soil physical and chemical properties of the analysis shows that the technology can effectively improve soil water storage capacity, the establishment of soil reservoirs, more importantly, can increase the amount of straw 20%, increase soil organic matter, fertility, increase Yield. Therefore, it is an effective way to promote water-saving agricultural technology in dry farming.
