荞麦在我国广泛分布,全国各地都有不同生态类型的荞麦栽培。但由于荞麦属小宗作物,比较分散,且多作为填闲复种,所以长期以来并未受到足够的重视。为了探索荞麦合理的种植密度,为荞麦栽培提供一定的依据,我们进行了这项试验,可供参考。材料与方法试验在清水县永清镇进行。试验地海拔1400米,塬地,土壤含有机质1.06％,全氮0.0639％,水解氮0.00731％,速效磷0.83mg/100g±,速效钾9.34mg/100g±, pH值为7.80。播前每亩施有机肥1000公斤。硝酸铵7.5公斤,过磷酸钙20公斤。以北海道荞为材料,试验共设5个处理,每亩保苗分别为4万株、6万株、8万株、10万株、12万株。随机排列,
Buckwheat is widely distributed in our country, all over the country have different ecological types of buckwheat cultivation. However, because buckwheat is a small number of crops, relatively scattered, and more as a reclamation, it has long been not enough attention. In order to explore the reasonable planting density of buckwheat, to provide a basis for the cultivation of buckwheat, we conducted this test for reference. Materials and Methods The experiment was carried out in Yongqing Town, Qingshui County. The experiment site was 1,400 meters above sea level with soil organic matter content of 1.06%, total nitrogen content of 0.0639%, hydrolyzed nitrogen content of 0.00731%, available phosphorus 0.83mg / 100g ±, available potassium 9.34mg / 100g ±, pH value 7.80. Before planting sowed organic fertilizer 1000 kg. 7.5 kg of ammonium nitrate, 20 kg of superphosphate. In Hokkaido buckwheat for the material, the experiment a total of five treatments, seedlings per acre respectively 40,000, 60,000, 80,000, 100,000 and 120,000. Randomly arranged,
