50年代至今,驻马店地区小麦生产水平得到大幅度提高,但由于气象灾害影响,产量波动较大。气象条件对产量影响关键时段在4月下旬到5月份,主导因子是降水,光照居第二位。小麦灌浆期光温水协调是高产的基本条件。小麦产量波动大的根本原因是科技水平较低,抗灾能力脆弱。当前应解决的问题是选用对路良种,提高播种质量,加强田间管理,合理施肥,提高抗灾能力。
Since the 1950s, the wheat production in Zhumadian area has been greatly improved, but due to the meteorological disasters, the output fluctuates greatly. Meteorological conditions on the yield of the key period in late April to May, the dominant factor is precipitation, light second place. Coordination of light, temperature and water during wheat filling is the basic condition of high yield. The fundamental reason for the large fluctuations in wheat production is the low level of science and technology and vulnerability to disasters. At present, the problem to be solved is to choose the right species to improve the quality of sowing, strengthen field management, fertilize rationally and improve resilience.
