去年我组在晚红薯上进行了钼肥不同施用方法的试验,取得不同的增产效果。现将试验情况介绍于下。试验地是早稻收获后肥力较差的粘土稻田,面积1.13亩,分为钼酸铵浸藤、拌火土盖藤、叶面喷雾和对照等五个小区。红薯品种为标心红。具体作法:浸藤每亩用钼酸铵100克,兑水溶解,栽插前浸1—2分钟;拌火土的亩用钼酸铵200克拌火土20担于栽插时盖藤;叶面喷雾的分
Last year, my group conducted experiments on different methods of application of molybdenum fertilizer on late sweet potato and achieved different stimulation effects. The test situation is introduced below. The test site is a paddy rice field with poor fertility after harvesting of early rice with an area of 1.13 mu. It is divided into five areas including ammonium molybdate dip vine, fire stalk vine, foliar spray and control. Sweet potato varieties as standard heart red. Specific practices: Baptist vine with ammonium molybdate 100 grams, watered dissolved, planted before dipping 1-2 minutes; mixed with fire Molybdenum ammonium molybdate 200 grams of mixed soil 20 Tam in planting plug vine; Foliar spray points
