为改变我县甜菜历年地硬、肥少、垄大、苗稀、防灾能力不强等粗放栽培方式,我们在三个大队进行了3万亩综合丰产试验。平均亩产高达3,931斤,比这三个大队前三年平均亩产2,131斤增产84.2%,比春订亩产指标3,000斤增加了31.2%。其中亩产超过2吨的为326亩,平均亩产4,467斤;超过亩产2.5吨的有165亩,平均亩产为5,067斤。甜菜含糖率分别达到了18.6—19%,比常规田提高0.3—1.0%。高产的经验概括起来是“两深、两增、两防”。 In order to change my county beet over the years hard, fat, big ridge, sparsely populated, strong ability to prevent such extensive cultivation, we conducted a comprehensive yield test of 30000 mus in three brigades. The average yield per mu is 3,931 kg, an increase of 84.2% from the 2,131-kg average mu yield in the first three years of these three brigades, an increase of 31.2% over the 3,000-kg per mu yield index. Among them, more than 2 tons of mu produce 326 mu, with an average mu yield of 4,467 kg; more than 2.5 tons of mu produce 165 mu, the average mu yield of 5,067 pounds. Sugar beet sugar content reached 18.6-19%, 0.3-1.0% higher than conventional fields. High-yielding experience can be summed up as “two deep, two increases and two defenses.”
