我区十年九旱,去冬今春以来雨雪又少,因此,如何抗旱保墒把地种好,已成为当前农事活动的关键一环。综合以往的经验,要注意抓好以下7项技术措施: 1.实地调查,掌握墒情。播种前要逐地块查看墒情,根据各地块的墒情安排播种顺序,确定具体播种时间和播种方法。对墒情好或易跑墒的地块,要提前抢墒播种,防止跑墒失水;对二阴地、冷浆地适当推迟播种期;对墒情不好的地块则要采取各种措施,抗旱播种。 2.细致整地保住墒。整地与不整地,整地质量的好环,对保持土壤水分、提高播种质量都有密切关系。实践表明,精细整地比一般整地的耕层土壤含水量高2～5％。整地时要抓住两个
Therefore, how to plan the drought-resistant soil moisture has become a key link in the current agricultural activities. Based on past experience, we should pay attention to the following seven technical measures: 1. Field survey to grasp the moisture content. Sowing plots before planting to see the moisture content, according to the plots of soil moisture scheduling arrangements for planting to determine the specific planting time and sowing methods. Moisture is good or easy to run moisture plots, to grab moisture sowing in advance to prevent running moisture loss of water; on the two overcast, cold slurry to delay the sowing period; the plot is not good for the water to take a variety of measures, Sowing drought. 2. Careful soil preparation to keep moisture. Soil preparation and irregularity, the good quality of the soil preparation ring, to maintain soil moisture, improve the quality of planting are closely related. Practice shows that the fine soil preparation than the average preparation of topsoil soil moisture content of 2 to 5%. When grading to seize the two
