摘要
山西农业增产的出路在于提高旱作农业的生产力,而旱作农业必须改变过去“以作物为主去找水”的办法,实行“以自然降雨为主定作物”的办法。出路何在提高旱作农业的生产力,之所以是山西农业增产的出路,主要有两方面的原因:1.
This paper suggests that the way out for increasing upland agricultural production is tochange the conventional method “searching for water according to crops” into the method“selecting crops according to natural rainfall”,synchronize water requirement of crops withrainfall,make full use of the aggregated precipitation in July-Sept.,grow short-season andhigh-yield crops,recommend plant-transfering cultivation and develope the method of waterreservation in tillage layers.At the same time,attentions should be paid to mulching filmpollution,timely relief for drought and water adjustment inside plant body.
