1982年我场9个基层生产单位,应用地膜覆盖技术栽培西瓜的面积达233亩,占全场西瓜种植总面积的18.5％。应用技术掌握较好的单位,增产效果显著,经济收入大幅度增加。据农科站、副业队和12队3个定点单位的记载,地膜覆盖栽培的西瓜平均亩产5881斤,比露地栽培平均亩产3840斤增产53.2％。但也有2队和14队,因蔓枯病严重危害,前期地膜覆盖所促进的营养生长优势,未能转化为增产效果,造成减产。这说明地膜覆盖栽培西瓜的前促优势如后期掌握不当就不能发挥作用。因此,地膜覆盖栽培仅是夺取西瓜优质高产的诸多综合措施之一。
In 1982, I field nine grassroots production units, the application of plastic film mulching watermelon covering an area of 233 acres, accounting for 18.5% of the total area of watermelon planting. Application of technology to master a better unit, a significant yield increase, a substantial increase in economic income. According to the agricultural station, sideline team and 12 units of 3 fixed-point records, the average yield of plastic mulching watermelon 5881 kg, more than the average yield of open-field cultivation 3840 kg 53.2% increase. However, there are also 2 teams and 14 teams. Due to the serious damage caused by the disease, the preponderance of vegetative growth promoted by plastic film mulching did not translate into increased yield and reduced yield. This shows that the advantages of plastic film mulching watermelon before the late grasp of improper can not play a role. Therefore, mulching is only one of the many measures to seize the high quality and high yield of watermelon.
