肥料是小麦营养上必需的养分。施肥是增加土壤养分,加强小麦营养,以提高单位面积产量的主要措施之一。施肥的多寡对于产量的高低有极大的影响。所以群众反映:“收多收少在于肥”,又“巧种地必须多上粪”,以及“麦收要好,上粪要饱”等。这是群众在生产实践中,证明了施肥对于增产所起的主导作用。但因目前肥源尚未充分利用,施肥面积和施肥数量尚为不足,所以小麦产量水平一般不高。我们为了研究充分利 Fertilizers are essential nutrients for wheat nutrition. Fertilization is one of the main measures to increase soil nutrients, enhance wheat nutrition and increase yield per unit area. The amount of fertilizer has a great impact on the level of production. Therefore, the masses reflect: “income and income are more than fat,” and “cleverly must be more on the manure,” and “wheat harvest is good, on the full manure.” This is the masses in production practice, proved fertilization for the leading role in increasing production. However, due to the fact that fertilizer sources have not yet been fully utilized, the area of ​​fertilization and the amount of fertilization are still insufficient, so the level of wheat yield is generally not high. In order to study fully profitable
