为提高复种指数,增加单位面积产量和产值,1998年我们承担了东营市科委下达的“黄河三角洲薯瓜(菜)间作套种高产高效开发试验”课题,其中对马铃薯套种西瓜的高产栽培模式进行了田间小区试验。一、供试品种马铃薯选用脱毒种薯鲁引1号,西瓜选用墨玉。二、套种方式 (一)四二式以3.8m为一种植带,带内播种四行马铃薯两行西瓜。马铃薯行株距为70cm×20cm,每亩3500株。西瓜两行间距40cm,株距45cm,西瓜与马铃薯间距为65cm,每亩780株。 (二)三二式(对照) 以3.1m为一种植带,带内播种三行马铃薯两行西瓜,马铃薯
In order to increase the multiple cropping index and increase the yield and output per unit area, in 1998 we assumed the task of “High Yield and High Efficiency Development Experiment of Intercropping Potato (Cucumber) Intercropping in the Yellow River Delta” issued by Science and Technology Commission of Dongying City, in which high-yielding cultivation of potato intercropping watermelon Mode of field plot test. First, the test varieties of potato detoxification seed selection Lu Lu No. 1, selection of watermelon jade. Second, intercropping methods (a) four two to 3.8m for a planting belt, sowing four rows of potatoes with two rows of watermelon. Potato line spacing 70cm × 20cm, 3500 acres per acre. Two rows of watermelon spacing 40cm, spacing 45cm, watermelon and potato spacing of 65cm, 780 per acre. (B) three two-type (control) Take 3.1m as a planting belt, three rows of potato sowing two rows of watermelon, potato
