一、夏播作物播前整地的特点: l、夏播作物早种一天即可增产,因此,一切措施必须在保证及时早播的前提下进行。 2、夏播整地时间短促,必须在最短时间内完成全部整地保墒作业。 3、夏播时气温高,土壤蒸发量大,必须及时保墒刻不容缓。二、夏播保墒技术: 1、在水利和劳力条件较好的地区,夏收后应立即进行耙地保墒灭茬,晚耙一天,板结的土层即会造成土壤水份大量流失,结合施基肥进行翻耕,改善土壤的板结状态,给作物造成良好的生育条件。耕后湮地,可采用小畦灌或开沟灌的方法,以节约用水并
First, the summer sowing sowing before planting the characteristics of land preparation: l, sowing crops as early as one day to increase production, therefore, all measures must be carried out under the premise of ensuring timely and early sowing. 2, Summer sowing time is short, all the land preparation must be completed in the shortest time. 3, summer sowing when the temperature is high, the soil evaporation, the timely preservation of moisture without delay. Second, summer sowing moisture conservation technology: 1, in water conservancy and labor conditions better areas, after the summer harvest should be rake to soil moisture stubble, late rake one day, the compaction of soil that will cause a large loss of soil moisture, combined with the base fertilizer Tillage, to improve soil compaction status, causing good crop conditions. Plowed land after plowing, can be used to ditch irrigation or ditch irrigation method to save water and
