今年,我们进行了西瓜短、密、早栽培丰产试验,初步取得了良好效果。试验于4月15日播种,6月25日采收,7月20日拉蔓,全生育期5天。亩产西瓜5250公斤,比露地西瓜提早上市20天左右,提高产量近一倍。其中四吨西瓜实收现金729元。 7月20日割老蔓时,距地面留下15—20厘米的茎,继续加强田间管理,利用西瓜茎基部萌发潜伏芽的特性,再生新蔓,开花结瓜,9月底再生西瓜成熟,亩产1500公斤。 西瓜短、密、早栽培是我所研究的新栽培技术。它是用我所选育的短蔓无叉西瓜品系,因其节间较短(3—5厘米),可使西 This year, we conducted a short, dense and early cultivation test of watermelon, and initially achieved good results. The experiment was sown on April 15, harvested on June 25, pulled on July 20, and the whole growth period was 5 days. 5250 kilograms per mu yield of watermelon, watermelon than the open market early 20 days or so, increase production nearly doubled. Four tons of watermelon which received 729 yuan in cash. July 20 when cutting the old man, leaving 15-20 cm from the ground stems, and continue to strengthen the management of the field, the use of watermelon stem base germinating latent buds characteristics, regeneration of new vine, flowering knot, by the end of September renewable watermelon mature, mu Produce 1500 kilograms. Watermelon short, dense, early cultivation is my study of new cultivation techniques. It is with my selection of short cross-necked no-watermelon lines, because of its internodes shorter (3-5 cm), you can make West
