Embodiment Construction

[0020] A method for building a greenhouse in a paddy field to cultivate lobsters, comprising the following specific steps:

[0021] (1) Select the water source with fresh water quality, no pollution sources around, and the water volume can meet the needs of breeding, so as to achieve long-term drought and long-term rain without waterlogging. At the same time, choose a clay paddy field and dig a ring ditch in the paddy field, 2m away from the ridge around the field. Dig into a ring ditch with a width of 5m at the top, 3m at the bottom and 0.8m in depth. The excavation area accounts for 10% of the total area of ​​the paddy field. When excavating, it is necessary to reserve a passage for machinery to enter the field, and set the water inlet and outlet diagonally at both ends of the paddy field. , and install a stainless steel anti-escape net to prevent crayfish from escaping when entering and exiting the water;

[0022] (2) Break up the remaining rice straw after harvesting and r...

Abstract

The invention discloses a method for cultivating lobster in a greenhouses constructed in rice fields, and the method comprises: excavating a ring groove in the middle of the rice field as a nursery pond for crayfish, arranging an aeration, water inlet and outlet equipment, and constructing a simple plastic greenhouse on the ring groove, increasing water temperature in winter by utilizing heat preservation effect of sunlight to ensure that the crayfish can safely overwinter; constructing slope protection vegetation by using water plants such as Elodea, creating suitable cave habitat for crayfish to effectively improve the survival rate and breeding rate of the parent shrimps; feeding high-quality feed for increasing the gonad development speed of female shrimps, realizing premature spawningand hatching, achieving the purpose of commercial shrimps early entering markets and improving the yield and economic benefits of shrimp farming in rice fields.

Description

technical field [0001] The invention relates to the technical field of lobster cultivation, in particular to a method for cultivating lobsters by building a greenhouse in a paddy field. Background technique [0002] Crayfish has been naturalized as an aquatic species in my country. It is an important aquatic economic shrimp species, which can expand the breeding area and alleviate the contradiction between supply and demand in the crayfish market. The implementation of paddy field cycle planting can effectively improve the water quality of paddy field wetlands, which is conducive to the protection of my country's agricultural ecological environment. At the same time, taking advantage of the crayfish's mixed feeding habits, crayfish can eliminate eggs and larvae in rice fields during the breeding process, thereby reducing the occurrence of insect pests in rice fields, reducing the amount and frequency of pesticide application in rice fields, and improving the quality and safe...
