1980年渠县良种场在进行甘蔗春育春栽的同时,作了春育夏栽试验,收效很好。春育春栽“川蔗6号”3.27亩,亩有效茎5000株,平均株高300.21厘米、茎径2.75厘米、茎重3.05斤、亩产7.68吨。春育夏栽甘蔗1.37亩(前作为板地小麦,亩产430斤),亩有效茎5350株,亩产6.17吨。1981年育苗移栽12.5亩,其中春育夏栽9亩(前作油菜,亩产218斤),经地县有关部门验收,甘蔗亩产5.6吨。加上国家补助粮食(亩产蔗茎基数1.5吨,每多产1吨甘蔗补助粮食200斤)800多斤,以及前作油菜,每亩折合粮食1000—1200斤左右。育苗移栽的优点:一是节约蔗种。育苗移栽甘蔗,每亩大田仅用种500—600斤,比秋植
In 1980, Quxian variety breeding farm was planted in spring and summer and summer planting with good results. Chunyu planted “Sichuan Cane 6” 3.27 acres, 5000 acres of effective stems, the average height of 300.21 cm, stem diameter 2.75 cm, stem weight 3.05 kg, per mu 7.68 tons. Spring and summer planting sugarcane 1.37 acres (formerly as a plate wheat, yield 430 kg), 5350 acres of effective stems, 6.17 tons of mu. In 1981 transplanted seedlings 12.5 acres, of which 9 acres planted in spring and summer (before the rapeseed, 218 kg per mu), the prefectural county acceptance, 5.6 tons of sugarcane per mu. Plus the state subsidies for food (mu cane base 1.5 tons per mu yield of 1 ton of sugar cane subsidies 200 pounds) 800 kilos, and before the rape, equivalent to 1000-1200 pounds per acre grain. Advantages of transplanting seedlings: First, save sugar cane. Seedlings transplanted sugarcane, only 500-600 kg per acre field, planting more than autumn
