Living environment of harvestmen: estuary or high intertidal zone, especially the benthic diatoms are rich in the area, the water quality is required to be free of industrial pollution and chemical pesticide residues, and the salinity is generally not more than 3%.
Organic fertilizers: According to the soil condition, put 500 to 1000 kilograms of fermented and rotted organic fertilizers per mu (dung of cows, sheep, chickens, ducks, geese and pigeons, piggery methane residue, etc.), to improve the structure of the soil.
Water
Water security: there are sufficient independent water supply sources throughout the year, to ensure that the grass bugs, rice growth during the water requirements, to prevent the upstream of other farmers, industrial pollution, pay special attention to kill snails, insecticidal pesticides contaminate the water source.
Harvest worm seedling placement: natural nauplii (splash seedling, the survival rate is low and affected by the climate), can also be manually replenish the seedling (100,000-200,000 tails of standardized rough seedling per mu).
