1983年我们在仁义公社以小蚕共育室补光育秧作了试验,收到明显效果。3月13日至4月10日,育秧三次,一次用种1,200—1,500斤,共用“汕优2号”种子3,865斤,移、直栽面积2,000余亩。育秧成本由该社1982年简易温室每斤种1.5元左右,降低为0.4元。小蚕共育室育秧的主要优点:①保温性能好。育秧一次只烧火三天多就停火,使温度保持自然下降,比简易温室节约烧火时间一半以上;②温差小。据测定,室内平均温度只相差0.32—0.71℃,前、后温度调节好后一般不超过2℃;③耗燃料少。育秧每斤种子仅消耗燃料1.12斤,比简易温室节约燃料7—8倍;④省工。育秧用种100斤花工11个,比简易温室节约人工3—4倍;⑤耗电费少。育种用种100斤花电费1.7元;⑥育秧后不影
In 1983, we renovated the seedlings of small silkworm reproductive nursery in Renyi Commune to make experiments. The results were obvious. From March 13 to April 10, the seedlings were planted three times with 1,200-1,500 catties at a time, sharing 3,865 catties of “Shanyou 2” with a total area of more than 2,000 acres. The cost of raising seedlings by the club 1982 simple greenhouse per kilogram of 1.5 yuan, reduced to 0.4 yuan. Small silkworm breeding room nursery main advantages: ① insulation performance. Raising seedlings once only burn more than three days to stop the fire, so that the temperature to maintain a natural decline, saving more than half of the time than the simple greenhouse burning time; ② small temperature difference. According to the determination, the indoor average temperature difference of only 0.32-0.71 ℃, before and after the temperature is generally not more than 2 ℃; ③ less fuel consumption. Raising seedlings per kilogram of seeds consume only 1.12 pounds of fuel, saving 7-8 times more fuel than the simple greenhouse; ④ provincial workers. Seedlings planted with 100 pounds of flower 11, 3-4 times more labor-saving greenhouse simple; ⑤ less power consumption. Breeding 100 kg spent electricity 1.7 yuan; ⑥ after the seedling does not affect
