自从改革农村经济体制后,农业生产形势很好,粮食生产和农业经济效益均稳定增长。但因各种原因,粮食生产仍不平衡。以我县为例,还有三分之一农田每亩年产量仍停留在千斤以下,甚至有16.7%的农田年亩产仅在800斤以下,与高产农田有着“一年不及一造粮”的差距。就土地的经济效益而言,不但低产田处于高消耗低效益的亏损窘境,高产田也普遍有高耗 Since the reform of the rural economic system, the situation of agricultural production has been very good with both the steady growth of grain production and the economic benefits of agriculture. However, food production is still uneven due to various reasons. In my county, for example, there are a third of the annual output of farmland per acre still remain below the kilogram, or even 16.7% of the farmland in only 800 kg per mu yield, with high yield farmland has a “less than one grain for a year” difference. As far as the economic benefits of land are concerned, not only are low-yielding fields in a predicament of high consumption and low efficiency, but also high consumption of high-yielding fields
