国营大曹庄农场地势低洼,土质粘重,不利于农业生产水平的提高。为此,1978年引进美国大型喷灌机8台,国产喷灌机9台。可浇地1.3万亩,占耕地70%以上。经多年调试观察证明,喷灌不仅具有省地、省工、省水、省时等优点,同时还能改变农田小气候和土壤物理性质,为作物的生长发育创造一个良好的农业生态环境。一、对农业生态环境的影响(一)减轻干热风危害,提高小麦产量。干热风是小麦生育后期的一种主要农业气象
Large state-owned Caozhuang farm low-lying, soil sticky, is not conducive to raising the level of agricultural production. To this end, in 1978 the introduction of the United States large-scale irrigation 8, 9 domestic irrigation machine. Can be irrigated 1.3 million mu, accounting for more than 70% of arable land. After years of commissioning, it has been proved that sprinkler irrigation not only has the advantages of saving land, saving labor, saving water and saving time, but also can change the microclimate of farmland and the physical properties of soil to create a good agro-ecological environment for crop growth and development. First, the impact on agricultural ecological environment (A) to reduce dry-hot wind hazards, improve wheat production. Dry hot air is a major agricultural meteorology in the later stages of wheat growth
