我省西瓜生产因气候条件的限制和栽培技术较差,单产和总产均不高,优质高档瓜所占比例小。为寻求适合我省气候条件的品种及相应的高产栽培技术,有利于改变我省西瓜产量低品质差的落后局面。我们于1988年在丹棱县唐河乡进行了无籽西瓜丰产栽培试验,并取得初步成功。无籽西瓜亩产4250公斤,平均单瓜重4.25公斤。瓜质上乘,不空心,可溶性固形物11.5％,脐部、蒂部皮厚0.8厘米,中部1.2厘米,肩部1厘米,瓜不开裂,耐贮运。其经济效益显著,商品瓜亩产4250公斤,均价0.70元/公斤,亩收入2975元,扣除种苗费200元,肥料费70元,农药费10元,地膜费40元,人工费155元,每亩纯收入2500元。创造了我省西瓜亩产值近三千元的高产纪录,为四川的西瓜生产提供了经验。主要技 Watermelon production in our province due to climatic conditions and poor cultivation techniques, yield and total production are not high, high-grade high-grade melons accounted for a small proportion. In order to seek suitable climatic conditions in our province varieties and the corresponding high-yielding cultivation techniques, is conducive to changing the low-quality watermelon yield in our poor backwardness. We conducted a test of high yielding seedless watermelon cultivation in Tanghe Township, Danling County in 1988, and achieved initial success. Seedless watermelon 4250 kilograms per mu, average weight of 4.25 kilograms of melon. Melon quality, not hollow, soluble solids 11.5%, umbilical, pedicle 0.8 cm thick, 1.2 cm in the middle, shoulder 1 cm, melon is not cracking, storage resistance. Its economic benefits are obvious. The output value of per mu of agricultural products is 4,250 kilograms, the average price is 0.70 yuan per kilogram, the income of mu is 2,975 yuan, the deduction of seedling cost is 200 yuan, the cost of fertilizer is 70 yuan, the pesticide fee is 10 yuan, the film fee is 40 yuan and the labor cost is 155 yuan. , 2,500 yuan per mu net income. The province has created a record high yield of nearly 3,000 yuan per mu of watermelon, providing experience for the production of watermelon in Sichuan. The main technique
