Lichenous what is suitable unripe long requirement?
One, alga of a network of rivers looks for green ball alga, be fond of strong light and high temperature, breed of alga of a network of rivers is very fast.
2, these a few kinds lichenous belong to green alga door, be fond of the environment with C, N, tall P, the pond of eutrophication grows easily.
3, lichenous belong to battalion zoogamy, slashing to nutrient requirement; Normally the to fertilize below the circumstance grows more easily than organic fertilizer, and packets of use is big organic fertilizer promotes flagellum alga to grow again, some flagellum alga make water system easily aglow, produce alga toxin, health of harm river crab grows, it is so when control of early days fat water is lichenous, the live thing that wants employ classics to had fermented organic fertilizer (professional manufacturer produces) .
4, lichenous grow quickly after rain, at the same time algae also can grow subsequently, but liver mosses of opposite Yu Qing is some slower.

Humic acerbity natrium kind effect time is short, need to increase dosage, cause side effect so big
3) half month left and right sides is used regularly can restrain lichenous growth product.
4) hold the crucial time place with lichenous processing. Will tell grass commonly dirty on those who hang is lichenous and firm evergreen can handle when liver mosses; And lichenous grow processing of a inch of above to be met compare difficulty relatively, have lichenous not hesitant, lichenous of course arrive more more than aquatic when, did not kill, lichenous killed grass to also won't grow. Accordingly, master the optimal time with good lichenous processing, did not delay.
