我县界沟乡是全县有名的低产穷乡,土壤瘠薄,低洼盐碱,生产落后。在1979年以前,全乡小麦、玉米单产在400斤左右。土壤普查查清了农业生产中的主要障碍因素是:土壤结构不良,养分含量较低,氮磷比例失调,地势低洼不平,排灌条件较差。为此,采取了一系列培肥改土措施,取得显著效果。一、增施有机肥为主,改良土壤结构该乡潮垆土占总耕地面积的38%,质地粘重,通透性差,适耕期短,有机质含量低,多在1%左右。我们采用了以增施有机肥为主,同时深翻,掺砂、炉渣等,改良土壤结构。有机肥来源:一靠“养”,大力发展畜禽业,以畜增肥。二靠“积”,广辟有机肥源,多积、多沤。三 My county Jigou Township is the county’s famous low-yielding poor township, barren soil, low-lying saline-alkali, backward production. Before 1979, the township, wheat, corn yields about 400 pounds. Soil survey identified the main obstacles in agricultural production are: poor soil structure, low nutrient content, the proportion of nitrogen and phosphorus imbalances, low-lying low-lying, poor irrigation and drainage conditions. To this end, adopted a series of measures to improve soil fertility and achieved remarkable results. First, the main application of organic fertilizer to improve soil structure The township tideland soil accounts for 38% of the total arable land, the texture sticky, poor permeability, short airspace, organic matter content is low, mostly about 1%. We used to increase the organic fertilizer-based, deep plowing, sand, slag, improve the soil structure. Source of organic fertilizer: rely on “support”, vigorously develop livestock and poultry industry, livestock and livestock manure. Two rely on “plot”, broaden sources of organic fertilizer, more plot, more 沤. three
