Rice and lobster co-cultivation method

Abstract

The invention discloses a rice and lobster co-cultivation method. By establishing a rice and lobster ecological co-cultivation system, through feeding activities of crayfishes, cooperated with the application of solar insect seducing insecticidal lamps, weeds and rice pests and diseases of rice fields are greatly reduced, the dosages of insecticides and pesticides are reduced, and rice flowers inthe flowering period can also be eaten by the crayfishes. The method also uses natural bait waterweed, tape grass, hydrilla verticillata and live snails as the food of the crayfishes, and improves thenutrient content of the crayfish, the taste and the nutrient components of the crayfishes are improved, the breeding cost is low, and natural baits of a rice field ecosystem and micro-ecological fodders are used for achieving the recycling of rice field materials, thereby not causing environmental pollution of an aquaculture water body.

Description

technical field [0001] The invention relates to the field of polyculture, in particular to a method for coculture of rice and shrimp. Background technique [0002] Rice and shrimp comprehensive farming is essentially an evolution and development of traditional rice field fish farming, and the agricultural sector also calls it "rice field comprehensive farming". Comprehensive rice and shrimp farming refers to the cultivation of aquatic animals (fish, shrimp, crab, etc.) It is an ecological agricultural method to produce rice and aquatic products by using internal nutrients and supplementing fertilizer and feed. However, the existing shrimp-rice continuous cropping method has a large gap between the rice planting period and the aquatic animal breeding period, which fails to effectively improve the utilization rate and overall efficiency of farmland. The short growth period leads to small size and poor plumpness of commercial shrimp. The seedlings are not guaranteed, resultin...

Problems solved by technology

However, the existing shrimp-rice continuous cropping method has a large gap between the rice planting period and the aquatic animal breeding period, which fails to effectively improve the utilization rate and overall efficiency of farmland. The short growth period leads to small size and poor plumpness of commercial shrimp. The seedlings are not guaranteed, resulting in unstable production and unsatisfactory economic benefits.
