Abstract

The invention discloses a method for culturing crawfish and removing weedy rice without ditching and bait casting in a plate type rice field. The method comprises the following steps: Step 1: choosinga suitable plate-type rice field and transplanting seedlings with water manually; Step 2: after harvesting rice, exposing the rice for 10-15 sunny days, and watering the field surface when the surface of standing rice stubbles becomes slightly yellow and crushed straws are all withered; Step 3: after the broken straw scattered in the field is basically decomposed, fermenting organic fertilizer inthe rice field, and harrowing the organic fertilizer evenly and leaving base fertilizer for future rice growth; Step 4: introducing water earthworms in the rice field after fertilization; Step 5: planting elodea and eyebright in strips in different areas; and Step 6: according to the degree of aquatic plant coverage and the number of early seedlings for breeding crayfish, restocking high-qualitycrayfish seeds at the right time. All the rice stalks are turned to the field after the rice is harvested without affecting the growth of crayfishes, so that the purpose of culturing the crayfishes and removing weedy rice in the plate type rice field without ditching and bait casting is achieved, and the culture efficiency of the rice field is improved.

Description

technical field [0001] The invention relates to the technical field of crayfish farming, in particular to a health-preserving rice dumpling and a preparation method thereof. Background technique [0002] Crayfish belong to Arthrophyta, Crustacea, Crawfishidae, Procambarus genus, also known as crayfish, scientific name Procambarus clarkii (hereinafter collectively referred to as crayfish), its meat is delicious and nutritious, and it is deeply loved by people. It is the main species of shrimp farming at present. In recent years, due to the sharp increase in market demand, the natural resources of crayfish have decreased sharply, and the price has gradually increased. Therefore, artificial scientific breeding is used to meet market demand. [0003] At present, rice and shrimp farming mostly uses ditches in rice fields, and bait is put inward during the breeding process, and weeds regenerate, which undoubtedly increases the cost of lobster farming and affects the growth of ric...
