Benefits of technology

This patented technology allows creation of crops that have stronger roots, resistant against harmful fungi, better nutritional value, longer life span than other types of vegetables grown on land. Green Prawnes grow well even at deeper waters without causing problems like soil erosion caused by rain falls during winter months. They use diktatery root plants called Diagridium spp., which helps keep their stalk upright while they form seedlings. By growing these seeds into large spaces around an area where there're no natural sources of contamination, this process makes up one clean source of indoor garden production.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency of raising fish populations while reducing their cost compared to other methods like feedings or artificially controllable crops for commercial use.

Abstract

The invention discloses a method for ecologically cultivating freshwater shrimps in a paddy. The method includes the following steps that the paddy is fertilized and then raked, a communicated cultivating ditch is excavated in the raked paddy, a field ridge is built around the cultivating ditch with excavated soil, the height of the field ridge ranges from 45 cm to 70 cm, and the width of the field ridge ranges from 60 cm to 90 cm; the cultivating ditch is provided with a water inlet and a drainage opening, the water inlet and the drainage opening are respectively provided with a device preventing the freshwater shrimps from escaping, a pond occupying 5%-8% of the area of the whole paddy is excavated on the water inlet, and the depth of the pond ranges from 80 cm to 110 cm; the paddy is sterilized through calcium oxide; seedlings of a rice variety are inserted into the sterilized paddy, wherein the stalks of the seedlings are thick and strong, the seedlings are resistant to lodging, diseases and fertility and grow in deep water, and the yield is high; the freshwater shrimps are fed after the seedlings turn green; bait is thrown during cultivating according to the freshwater shrimps in different growth stages, and meanwhile water keeps clean. The freshwater shrimps cultivated in the method are natural and free of pollution and are pure green food.
