坝上地处我省北部高寒区,气候冷凉,昼夜温差大,适合马铃薯生长。历年播种面积较大,是全国马铃薯产区和种薯基地之一。为进一步提高马铃薯产量,在海流图职中农场选择2亩沙壤地进行了试验,平均亩产达2500公斤,其栽培技术措施是: 一、精细整地。在秋耕地的基础上,早春土壤解冻时及时进行耙耱镇压,创造良好的土壤环境。 二、选用良种。据试验,可选用高产、优质、抗逆性强的“克星一号”旱地马铃薯。 三、施足底肥。亩施腐熟圈肥5000公斤,过磷酸钙20公斤作基肥。15公斤碳酸氢铵作种肥。种肥一定要掌握在空犁施或点施在两穴之间,以防化肥烧苗。 四、把好播种关。为了获得健壮幼苗,
Bashang is located in the northern alpine region of our province, cold climate, large temperature difference between day and night, suitable for potato growth. Sowing a large area over the years, is the country’s potato producing areas and seed base. In order to further improve the yield of potato, we selected 2 mu of sandy soil from the farm of Hailuogou for an average of 2,500 kg per mu. The cultivation techniques and measures are as follows: 1. Finely ground the soil. On the basis of autumn cultivated land, raking and repression of soil in early spring thawed in time to create a good soil environment. Second, the selection of seeds. According to the test, you can use high yield, high quality, strong resistance “nemesis” dry land potato. Third, Shi enough base fertilizer. Mushi rotten circle fertilizer 5000 kg, 20 kg of superphosphate as a base fertilizer. 15 kg of ammonium bicarbonate as seed fertilizer. Kind of fertilizer must be grasped in the air plow or point between the two points in order to prevent chemical fertilizer burn seedlings. Fourth, good sowing off. In order to obtain robust seedlings,
