甘蔗大多在春天种植,即2～4月份,此时用种量大,种茎大多为头年春植蔗。由于种茎茎径大、重、芽老化发芽率较低,一般一吨蔗种约有7000～8000个芽,每亩用种量大约在0.7吨左右。如种茎为头年夏(秋)植蔗,种茎小、发芽率高,一般一吨蔗种约有12000～15000个芽,每亩用种量0.3～0.4吨即可。近年来北海、钦州等地的蔗农正是利用综上所述这一特点,大力发展夏植蔗 Most of the sugar cane is planted in the spring, that is, from February to April, at this time with a large amount of seed, mostly in the first year of planting stem cane. As the stem stem diameter, weight, bud aging germination rate is low, generally about a ton of sugarcane 7000 ~ 8000 buds, with about 0.7 tons of seed per mu. If the stems for the first year summer (autumn) planting sugarcane, small stems, germination rate is high, generally a ton of sugarcane about 12,000 ~ 15,000 buds, the amount of 0.3 ~ 0.4 tons per mu can be. In recent years, Beihai, Qinzhou and other places of sugarcane farmers is the use of the above summary of this feature, vigorously develop summer sugarcane
