四川渠县花龙、静边等乡农民,为发挥办沼气的效益,用沼液浸种,沼渣地膜育秧代替药液浸种,温室育秧,取得了好效果。此法有耗能少、成本低、操作简单、节省用工、管理方便、不烂种、发芽快、出苗整齐、秧苗粗壮、成秩率高等优点,深受欢迎。一、沼液浸种与发芽3月8—15日,将优良的杂交稻种,晒两天,3月16日,用塑料编织袋装好稻种(每袋不超过5公斤),吊在正常产气的沼气池出料口的沼液中层。3月19日,取出用清水洗净,用26℃的温开水浸2—3分钟,然后用纱布包好放入青杂草堆(60公斤左右)内发芽,温度不超过38℃,20—24小时谷种破胸后,用25—30℃温开水过两次,20小时后,当根长到一粒谷长,芽长到半粒谷长时,立即播入秧床,以防断芽。二、沼肥地膜育秧修建秧床。1公斤谷种需秧床3.6平方米,选在背风向阳的地方建造,宽0.5米、深0.2米、埂宽0.15米,长度据需要定,四周夯实,床面要求细碎、平整。制作营养土。取沼渣,去粗壳,晒干粉碎;取菜园土,晒干,
Sichuan Quxian spent dragon, static and other township peasants, to play the benefits of doing biogas, soaking with biogas slurry, biogas residue film instead of liquid seedling soaking, greenhouse nursery, and achieved good results. This method has the advantages of low energy consumption, low cost, simple operation, labor-saving, convenient management, non-rotten, fast germination, emergence and tidiness, seedling robustness and high rank rate. First, biogas slurry soaking and germination March 8-15, the excellent hybrid rice, sun two days, March 16, with a plastic woven bags of rice (not more than 5 kg per bag), hanging in the normal Production of biogas digesters at the outlet of the middle of the biogas slurry. March 19, remove the wash with water, soaked with warm water at 26 ℃ for 2-3 minutes, and then wrapped with gauze into the green weed heap (60 kg or so) germination, the temperature does not exceed 38 ℃, 20- Twenty-four hours after threshing chest, with 25-30 ℃ warm water twice, 20 hours later, when the root length to a grain length, bud length to half a grain length, immediately sow seedlings to prevent bud. Second, biogas film seedling cultivation seedling cultivation. One kilogram of seed need seedbed bed 3.6 square meters, the election leeward sunny place, width of 0.5 meters, 0.2 meters deep, width of 0.15 meters, according to the need to set the length, surrounded by compaction, the bed requires crushing, smooth. Making nutritious soil. Take biogas residue, to the coarse shell, dried crushed; take garden soil, dried,
