我县位于黄海之滨,西部、北部和山东接壤,每年种植岭麦15万亩,占三麦总播种面积的四分之一。由于岭地缺水,缺肥、土层浅、土质差,三麦产量一直较低,单产仅在300斤左右,是我县三麦生产的拖腿田。因此,总结岭麦种植经验,采取有效措施,迅速改变低产面貌,已是势在必行。一、岭麦低产原因(一) 土层浅,肥力低岭地土壤风化程度差,土粒粗,土层浅,养分含量低。据测定,包浆岭砂土、酥石岭砂土,熟土层厚度仅15厘米左右,土壤中含有机质、速效磷、速效钾、全氮分别在0.6%、6ppm、50ppm、0.05%左右。
My county is located in the Yellow Sea coast, west, north and Shandong bordering each year planting 15 million mu of ridge wheat, accounting for a quarter of the total sown area of three wheat. Due to lack of water in the ridge, lack of fertilizer, shallow soil, poor soil quality, the yield of Sanmai has been low, yield of only about 300 pounds, is the production of the county three wheat drag legs. Therefore, summarizing the experience of planting wheat and taking effective measures to rapidly change the appearance of low-yielding is imperative. First, low-yielding wheat causes (A) shallow soil, low fertility and low weathering weathered soil, coarse soil, shallow soil, low nutrient content. According to the measurement, the content of organic matter, available phosphorus, available potassium and total nitrogen in BaoLongLing sandy soil, silisslion sandy soil and mature soil layer is only about 15 centimeters, which are 0.6%, 6ppm, 50ppm and 0.05% respectively.
