为了阐明柑桔栽密植度与产量的关系,我们在乐清县湖务乡选择了具有代表性的二亩塘田作试验园,除去四周的保护行0.4亩,实际面积1.6亩,等分成八块,每块0.2亩,为一处理,四块为一试验小区,二个重复。选一年生枳砧兴津温州蜜柑作试材,设亩栽600株、300株、150株及50株四个处理。1984年3月进行定植,随机排列。定植前,试验园全面撒施10吨腐熟栏肥并进行深耕。技术措施,除夏秋梢适时摘心,促进枝梢粗壮,分枝多,及时整枝抹芽,调整树冠使之均匀紧凑,增加2次施肥次数,其他管理与一般桔园相同。 1984年定植当年,因管理疏忽,长势一般。1985年加强管理,落实了措施,1986年开始结果,结果树达487株,占种植总株数564株的86.3％,产量达1032.5公斤,折亩产645.31公斤,平均株产1.83公斤,其中最高株产5.3公斤。
In order to clarify the relationship between planting density and yield of citrus trees, we selected a typical two-acre pond Tian as a test garden in Huzhou Township, Yueqing County, except for 0.4 mu of protected areas in the four weeks and the actual area of 1.6 mu, which is divided into eight , Each 0.2 acres, as a treatment, four for a pilot area, two repeated. An annual selection of Citrus aurantium Wenzhou Satsuma test material, set acres planted 600, 300, 150 and 50 four treatment. March 1984 colonization, random arrangement. Before planting, the test garden fully cast 10 tons of compost column fertilizer and deep plowing. Technical measures, in addition to the summer tip of a timely manner topping, to promote stout stout, more branches, timely pruning buds, crown adjustment to make uniform and compact, increase the number of 2 times the fertilization, other management and the same orange garden in general. The year of colonization in 1984, due to management negligence, growing in general. 1985 to strengthen management and implement measures, the results began in 1986, the results of 487 trees, accounting for 86.3% of the total number of 564 plants planted, the output reached 1032.5 kg, 648.31 kg per mu yield, the average yield of 1.83 kg, of which the highest strain Produce 5.3 kg.
