我们这里地处丘陵山区,几乎年年发生春旱。有些坡度大,离水源较远的地块,很难做到抗旱播种保苗。近几年来,我们在一犁左右没墒或略有墒情而种子很难发芽的地块,采用巧夺底墒的播种方法,取得了很好效果。 具体做法如下: 1.第一犁开沟。事先在犁铧上绑个小草把,开沟时将表层干土推向两边,并防止干土复回沟内(见图1)。 2.第二犁在第一犁走过的沟内用新柳铧深开沟(不带推土草把), Here we are located in hilly areas, spring drought occurs almost annually. Some steep slopes, far from the water plots, it is difficult to do drought planting seedlings. In recent years, we did not sip soil moisture or a slight moisture content and the seeds are difficult to sprout plots, using the seizure of sowing seeding methods, and achieved good results. Specific practices are as follows: 1. The first plow ditch. Plowshare in advance tied a small grass, when the ditch will push the dry soil surface to both sides, and to prevent dry soil back into the ditch (see Figure 1). 2. The second plow in the first plow through the trench with the new Liuhua deep trench (without soil to grass),
