温州蜜柑刚进入结果的树,有许多果实皮厚、贪青、味淡,果农俗称“青皮疙瘩”,我们暂称为青浮皮果。近年来,笔者从7月份株施氮75克、100克、150克、225克、350克,450克和不施氮的试验中发现,氮素用量过多是诱导产生青浮皮果的主要原因之一。 我们将试验结果中株产10-19公斤这一段产量的青浮皮果率加以平均,经统计分析看出,青浮皮 Wenzhou Satsuma just entered the results of the tree, there are many thick fruit, greedy, tasteless, fruit growers commonly known as “green skin lumps,” we tentatively referred to as green-skinned fruit. In recent years, the author found that 75% of nitrogen applied in July was 100 grams, 150 grams, 225 grams, 350 grams, 450 grams and no nitrogen application. It was found that the excessive use of nitrogen was the main reason one. We will test results in strains produced 10-19 kilograms of blue-green peel rate of the average yield, the statistical analysis shows that the green skin
