1990年河北省植棉面积恢复到90.7万公顷。由于平均每公顷产量不足630公斤,皮棉总产只有57万吨,低于“七五”期间平均690公斤的水平。棉花单产水平较低,原因是多方面的,棉田投入减少,用地质量降低,是影响产量的重要因素。因此,提高棉田质量,增加物质投入,应是当务之急。 In 1990, the cotton area in Hebei Province was restored to 907,000 hectares. Since the average yield per hectare is less than 630 kg, the total lint output is only 570,000 tons, which is lower than the average level of 690 kg during the “Seventh Five-Year Plan” period. Low yield of cotton, due to many reasons, reduced input in cotton, land quality is reduced, is an important factor affecting the yield. Therefore, to improve the quality of cotton fields and increase material inputs should be top priorities.
