池塘施绿肥常引起浮头,这是因为在植株分解的生化过程中,氧化反应消耗水中大量溶解氧。绿肥分解的最初几天,容易矿化的有机质先行氧化,这一过程尤其强烈。我们的试验是将腐烂分解过程移到池外进行,而后再作为富菌腐屑施入。根据萨马林和B_1A阿基莫夫用细菌饵料~*喂鲤鱼和植食性鱼类幼鱼的实验资料,可以推测即使池塘内投入数量不大的细菌饵料(30天的投饵量为40—45公斤/公顷),浮游动物生物量一般就能提高2倍。
Pond green manure often cause floating head, which is because the decomposition of plants in the biochemical process, the oxidation reaction consumes a lot of dissolved oxygen in water. The first few days of decomposition of green manure, easy mineralization of organic matter first oxidation, the process is particularly strong. Our experiment is to move the decay decomposition process to the outside of the tank, and then put it as rich bacteria decay. According to the experimental data of Samarin and B_1A Akimov using bacterial bait * to feed carp and herbivore juveniles, it can be inferred that even if a small amount of bacterial bait was put into the pond (the feeding amount for 30 days was 40 - 45 kg / ha), zooplankton biomass can generally be increased by 2 times.
