平和琯溪红瓤蜜柚栽培初步研究

The Primary Study of Guanxi Red-Fleshed Honey Pomelo's Cultivation in Pinghe County

对平和县琯溪蜜柚新品种红瓤蜜柚进行了连续6 a的栽培试验,结果表明:酸柚、土柚和枳作为红瓤蜜柚的砧木对嫁接成活率影响不大,但酸柚种子的发芽率较高;酸柚种子采用果藏法最好,当年采种,当年播种、育苗;春梢夏秋单芽腹接或秋梢春季单芽切接成活率都较高;造林密度Ⅰ类地以每600株.hm-2为好,Ⅱ类地以每750株.hm-2为佳;种植绿肥加施有机厩肥比施用化肥加锄草深翻的抚育方式果实的品质更好;高接换种可有效地改造不良蜜柚品种。

6-year-continuing-long culture experiment of the Guanxi red-fleshed honey pomelo＇ s cultivation in Pinghe County was conducted, the results showed lime, and Poncirus trifoliate had small effects on the engraft survival rate as red-fleshed honey pomelo＇ s rootstocks, but lime seed germination rate was high;fruit-storage method was best for lime seed, seed was collected in current year, and insemination and seedling raising were conducted in current year; the survival rates were relatively high with 2 engraft methods introduced in this paper; the afforestation density was best, 600 treees/hm^2 for I type of land, and best, 750 trees/ hm^2 for Ⅱ type of land;the fruit quality with applying green fertilizer with organic manure was better than the quality with applying chemical fertilizer with weeding and perform deep tillage; top grafting could effectively improve bad honey pomilo variety.
