我省丘陵旱地约占丘陵总耕地面积的60％,如何进行耕作制度改革,是值得很好研究的问题,现仅就我们的实践,提出两点建议。一、关于三台地的改制问题我省丘陵三台旱地近600万亩,土薄怕旱,结构差.养分缺,坡度大,冲刷严重。据水文部门测定,5—15度的坡地,每年每亩被雨水冲走泥沙4—11吨、氮素3.85斤、磷0.29斤、钾2.12斤。由于旱、薄、瘦、冲刷等原因,这些地一般只能种一些小杂粮或薯类作物,产量很低。
Hilly dryland in our province accounts for about 60% of the total cultivated land in the hills. How to carry out the reform of the farming system is a question that deserves a good study. Only two suggestions are made regarding our practice. First, on the reform of the three sets of problems In our hilly three dry land nearly 6 million mu, soil thin, afraid of drought, poor structure, lack of nutrients, slope, serious erosion. According to the hydrological department, 5-15 degrees of slope, each mu per year was washed away 4-14 tons of sediment, nitrogen 3.85 pounds, 0.29 pounds of phosphorus, potassium 2.12 pounds. Due to drought, thin, thin, scour and other reasons, these areas generally can only grow some small grains or potato crops, the yield is very low.
