砂礓黑土,占王桥公社粮田面积的60％以上,是影响农业高速度发展的坠脚田。其低产原因是“涝”、“旱”、“瘦”、“礓”。1975年以来,采取以改土治水为中心的综合农业技术措施,收到了明显的效果。我站400亩粮田,在原来亩产小麦百斤左右的基础上,去年突破了300斤,今年播种270.4亩,平均亩产达到了423.5斤,其中50亩丰产田达到640斤,并出现小面积800斤以上的地块。试验方内的各生产队小麦产量也创历史最好水平,一般增产2—3成。我们采取的主要措施是:
Sand 礓 black soil, accounting for more than 60% of Wangqiao commune grain area, is the impact of agricultural development of the high-speed foot-field. The reason for the low yield is “waterlogging”, “drought”, “thin”, “礓.” Since 1975, the adoption of comprehensive agro-technical measures centered on the improvement of soil and water has received significant results. I station 400 acres of grain, in the original yield of about 100 kilograms of wheat, last year exceeded 300 pounds, 270.4 acres planted this year, the average yield reached 423.5 pounds, of which 50 acres of high-yield fields reached 640 pounds, and the emergence of small Area of more than 800 pounds of land. The wheat production in each production team in the trial side also hit a record high, with a general increase of 2-3%. The main measures we take are:
