在分析河套灌区春小麦生产中的春季潮塌、干热风和小麦全蚀病等农业气象灾害和病害的成因、发生时段与危害程度后,有针对性地进行了广泛调查、研究、总结和示范,重点试验推广了适时早播、选取良种、缩垅增行、优化密度和带状立体种植及适时适量、优化灌溉等一系列减灾对策与配套技术,有效地避免或减轻了灾害,促进了小麦生产持续4年攀登新台阶。单产平均每年递增29.9kg,增产13.0%,总产平均每年递增7349.0万kg,增产16.48%,获得了显著的减灾增产效果。
After analyzing the causes, occurrence periods and hazards of agricultural meteorological disasters and diseases such as spring tide collapse, dry hot wind and total eclipse of wheat in the spring wheat production in Hetao Irrigation District, we carried out extensive investigation, research, summary and demonstration, The key trials promoted a series of disaster mitigation measures and supporting technologies such as timely early sowing, selection of improved varieties, expansion of shrubs, optimization of planting density, three-dimensional planting and timely and proper irrigation, and optimization of irrigation so as to effectively avoid or mitigate disasters and promote wheat production 4 years to climb to a new level. The average annual yield increased by 29.9kg, an increase of 13.0%, with an average annual increase of 73.499 million kg of total output, an increase of 16.48%, and achieved remarkable disaster reduction and stimulation effects.
