黑龙港沧州平原区位于黑龙港平原北部,占黑龙港平原总面积的34.9%。沧州平原区是河北省重要冬小麦产区,常年播种面积约为36.7万hm2,占全省冬小麦播种面积的1/6。合理施肥是作物高产栽培的重要环节,尤其是对于冬小麦这种需肥较多的作物而言,科学合理的施肥对于保证小麦正常生长发育,促进小麦高产具有重要意义。实际上,合理施肥的重要性是众所周知的,但在生产实践中,却依然很难做到“科学合理”。具体来
The Cangzhou Plain in Heilongjiang is located in the northern part of the Heilonggang Plain, accounting for 34.9% of the total area of the Heilonggang Plain. Cangzhou Plain is an important winter wheat producing area in Hebei Province. Its perennial planting area is about 367,000 hm2, accounting for 1/6 of the sown area of winter wheat in the province. Reasonable fertilization is an important part of high-yielding crops, especially for winter wheat, which needs more fertilizer. Scientific and reasonable fertilization is of great significance to ensure the normal growth and development of wheat and to promote high-yield wheat. In fact, the importance of proper fertilization is well known, but it is still hard to be “scientifically sound” in production practice. Specifically
