Green three-dimensional planting method of rice and shrimp symbiotic defense against natural enemies

Abstract

The invention provides a symbiotic natural-enemy-preventing green stereoscopic planting and culturing method for paddy rice and lobsters. The method comprises the following steps: (A) carrying out field preparation: excavating interpenetrating trenches around a rice field, and laying limiting frames in the trenches, wherein the limiting frames are divided into a plurality of different functional areas; (B) injecting water into the trenches, and separately planting a variety of aquatic crops in the functional areas; (C) sowing paddy rice seedlings in the rice field; (D) adding juvenile lobsters of a first season; (E) carrying out a field management stage, of which a main job is to add a feed for the juvenile lobsters, carry out water surface management and complete the fishing of adult lobsters of the first season and adding of juvenile lobsters of a second season in good time; and (F) carrying out paddy rice harvesting, and fishing adult lobsters of the second season. According to the method, the symbiotic growth of the paddy rice, the lobsters and the aquatic crops can be achieved, and a primary environment is simulated; a green stereoscopic protective screen can be created so as to keep away natural enemies of the juvenile lobsters; and paddy rice insect pests can be controlled through biological means so as to reduce pesticide application, and aquatic ornamental crops and aquatic economic crops can be planted simultaneously so as to achieve yield increase and income increase.

Description

technical field [0001] The invention relates to the field of crayfish cultivation, in particular to a green three-dimensional cultivation method for symbiosis of rice and shrimp to prevent natural enemies from increasing bait. Background technique [0002] Crayfish belong to Arthrophyta, Crustacea, and Procambarus genus. The scientific name is Procambarus clarkii. Its meat is delicious and nutritious, and it is deeply loved by consumers. Crayfish have a variety of food habits and strong environmental adaptability. An ideal variety for increasing production and income. [0003] In the prior art, crayfish are generally stocked in shallow water ponds, and the amount of bait put in is large, which is not conducive to reducing the cost of cultivation; in addition, crayfish are omnivorous animals, and the bait artificially put in is mainly protein feed, which is different from the food raw materials in the natural living environment of crayfish. There is a large difference in the...

Problems solved by technology

[0003] In the prior art, crayfish are generally stocked in shallow ponds, and the amount of bait put in is large, which is not conducive to reducing the cost of cultivation; in addition, crayfish are omnivorous animals, and the bait artificially put in is mainly protein feed, which is different from the food raw materials in the natural living environment of crayfish. There is a large difference in the ratio, resulting in an unbalanced intake of plant-based and animal-based nutrients in crayfish, which affects the yield and quality

Crayfish need to shed their shells during their growth and development. They grow in a shallow water environment and have weak self-defense capabilities against natural enemies such as water birds.
