小麦适期早播配合适当稀植,是近几年大力推广的一项抗灾高产栽培技术。据湖北省农业厅在7个县市连续两年试验结果,比常规栽培增产12％～16％。随州市各试验示范点均增产一成以上。 适期早播,是以满足小麦冬前形成壮苗所需的积温,而又不致引起冬季拔节为原则。这样,既能充分利用秋末的温光资源,使麦苗在冬前有足够的时间发根分蘖,形成强健的营养体,又可避免过 Suitable early planting of wheat with appropriate sparse planting, is vigorously promoted in recent years, a high-yielding cultivation techniques. According to Hubei Provincial Department of Agriculture in seven counties for two consecutive years of test results, than conventional cultivation yield 12% to 16%. Suizhou pilot sites have all increased by more than 10 percent. Suitable early sowing, so as to meet the winter wheat seedlings needed to form the accumulated temperature, but will not cause the principle of winter jointing. In this way, not only can we make full use of the late autumn light resources, so that wheat seedlings have enough time before winter root tillers to form a strong nutrition, but also to avoid
