我县耕地土壤大部分为丘陵红壤坡地,普遍缺乏微量元素。因此,在农业生产中广泛应用微量元素肥料。是提高稻麦作物产量和品质的有效方法。近年来,在全县进行了钼酸铵、硼砂、以及硫酸锰的对比试验和大面积示范推广,取得一定效果。现将有关资料报告如下: 一、施用微量元素的增产效果近年来,对上述三种微肥先后进行了十七次试验获得增产的13次,平均每亩增产50.1斤,增产率达10.7％左右。 1.钼肥: 对小麦等作物使用钼肥有一定的增产作用。一般每亩可增产24.3斤,增产5.9％。水稻每亩增收稻谷22-90斤,平均每亩增产
Most of the cultivated soils in our county are hillsides of red soil in hilly areas, and the trace elements are generally lacking. Therefore, trace element fertilizers are widely used in agricultural production. It is an effective way to improve the yield and quality of rice and wheat crops. In recent years, the county conducted a comparison test of ammonium molybdate, borax and manganese sulfate and large-scale demonstration and promotion, and achieved some results. Now the relevant information is reported as follows: First, the application of trace elements of the yield effect In recent years, the above three kinds of micro-fertilizer has conducted seventeen trials to increase production of 13 times, an average yield of 50.1 kg per mu, yield rate of 10.7% . 1. Molybdenum fertilizer: the use of molybdenum fertilizer on crops such as wheat has a certain role in increasing production. Generally increase yield per mu 24.3 kg, an increase of 5.9%. Paddy rice 22-90 pounds per acre increase, the average yield per mu
