嘉荫农场地处高寒地区,土壤多为岗地白浆土,渗水不良,十年六春涝。因此,抗春涝保春种已成为这个场春播阶段的重要工作。1988年严重春涝,机车不能下地,整地作业迟迟不能进行,到4月末,小麦仅播5.4%。在这种情况下,我们改顺垄深忪为斜向深松散墒。先在十四、十五、十七队示范,效果十分理想。接着通过电视在全场推广。每个班次作业量平均为225亩,昼夜都可进行作业。全场用此法散墒面积共7.7万亩,占小麦播种面积的75%。一、具体方法1.主要应用在头一年垄作大豆茬或田间清理较干净的玉米茬上。用拖拉机液压悬挂深松机与垄向保持45°角进行斜向行走。2.深松铲的距离可视墒情而定。土壤含水量大时,可用70厘米铲距,避免堵塞;土壤含水量较小
Jiayin Farm is located in the alpine region, the soil is mostly white clay soil, poor water seepage, ten years of six spring floods. Therefore, spring and flood protection spring species has become an important part of this spring sowing stage. In 1988, severe floods and floods, locomotives could not go to land, and land preparation work was delayed. By the end of April, wheat only sows 5.4%. Under such circumstances, we have modified the ridge depth to slash loose soil moisture deeply. First in the fourteen, fifteen, seventeen team demonstration, the effect is very satisfactory. Then through television to promote the audience. The average workload of each shift is 225 mu, which can be carried out day and night. The audience scattered soil with a total area of 7.7 hectares, accounting for 75% of the area planted with wheat. First, the specific method 1. The main application in the first year of ridge crop stubble or field clean up more clean corn stubble. Tractor hydraulic submersible subsidence with the ridge to maintain a 45 ° angle for walking obliquely. 2 deep shovel distance depending on the amount of moisture may be. Soil moisture is large, available 70 cm shovel to avoid clogging; soil moisture content is smaller
