去年,我省遭受了历史上罕见的洪涝灾害,使大面积的低洼耕地遭受水害,既造成当年严重减产减收,又给今年春耕播种带来了一定的困难。对这些水淹的耕地,采取哪些措施,才能保证适时地种上种好,做到一次播种拿全苗,这是关系到今年农业增产增收的一个至关重要的大问题。水淹地的主要特点 (一)土壤含水量大,有些低洼地块一直被水泡着: (二)土壤被洪水冲刷严重,各种养分流失较多,致使地力大大下降; (三)土壤板结,通透性能差;杂草多,易造成草荒; (四)土壤冷浆,地温低,易造成坏种; (五)春季土壤返浆重,煞浆迟,给适时播种带来很大困难。对水淹地采取的措施 (一)利用冬春季节,刨出田间冻水。有些低洼地的积水已结冰,可利用冬春闲季,
Last year, our province suffered a rare flood disaster in history, causing large areas of low-lying arable land to suffer water damage, which not only resulted in a serious reduction in production and reduction in the current year but also brought certain difficulties in planting this spring. What measures should be taken on these flooded cultivated land so as to ensure timely planting of all kinds of seedlings so that the whole plantation can be sown once and for all? This is a crucial issue concerning the increase of agricultural output and increase of output this year. Main Features of Flooded Land (i) Large soil moisture content, some low-lying land blocks have been blistered with: (2) The soil is seriously washed by the flood and more nutrients are lost, resulting in a great decrease in soil fertility; (3) (4) soil cold slurry, low ground temperature, easy to cause bad species; (5) the spring soil back to heavy pulp, late pulp evil, timely sowing to bring great difficulties. Measures taken for the flooded ground (a) the use of winter and spring, planing field frozen water. Some low-lying water has been frozen, available winter and spring leisure season,
