Method for comprehensively raising various types of aquatic livestock and cultivating paddy in paddy field

Abstract

The invention relates to a method for comprehensively raising various types of aquatic livestock and cultivating paddy in a paddy field, in particular to the raising of Chinese soft-shelled turtles, crawfish and carassius auratus gibelio in the paddy field and the cultivation of paddy. The method comprises the steps of paddy field preparation, aquatic plant transplantation, live food feeding, paddy transplantation, young aquatic livestock placement, bait feeding, daily management, aquatic livestock fishing and paddy harvest. The method for comprehensively raising various types of aquatic livestock and cultivating paddy in the paddy field has the advantages that the various types of aquatic livestock can be raised and paddy can be cultivated in the same field comprehensively, the difference between the period for paddy cultivation and the period for raising aquatic livestock is small, the use rate and the comprehensive efficiency of the field can be effectively improved, and economic benefit can be improved to a large extent; meanwhile, any chemical fertilizer, herbicide and insecticide are not used in the process of production, the produced products can meet the standard of organic food, and finally, edible safety of the products is achieved; the whole process of production is beneficial to conservation of water and soil of the field and the surrounding environment and effectively facilitates the protection of natural ecology.

Description

technical field [0001] The invention relates to a method for comprehensively cultivating various aquatic animals and planting rice in a paddy field, in particular to the cultivation of soft-shelled soft-shelled turtle, crayfish, and heterogeneous gibel crucian carp in a medium paddy field and the planting of rice, belonging to animal breeding and The field of rice cultivation technology. Background technique [0002] Existing methods for carrying out aquatic animal breeding and rice planting in paddy fields are as follows: [0003] The first is fish farming in rice fields. Its disadvantages are: single aquatic animals, short growth period, low yield, poor economic benefits, and some contradictions between rice and fish in drying fields, fertilization, and pesticide application. [0004] The second is the continuous cropping of shrimp (crayfish) and rice. Its disadvantage is that there are only a few aquatic animals, and there is a large gap between the rice planting period ...

Problems solved by technology

[0003] The first is fish farming in rice fields. Its disadvantages are: the aquatic animals are single and the growth period is short, the yield is low, and the economic benefits are not good. There will also be certain contradictions when rice and fish are drying the fields, fertilizing, and applying pesticides.

[0004] The second is the continuous cropping of shrimp (crayfish) and rice. The disadvantage is that there is a single aquatic animal, and the time period for rice planting and aquatic animal breeding is quite different, 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

Due to the lack of guarantee of seedlings, the output is unstable and the economic benefits are not ideal

[0005] The third is to raise crabs in rice fields. The disadvantages are that the rice output is limited, the growth rate of river crabs is slow, and the phenomenon of precocious maturation is serious, which leads to small size and low price of commercial crabs, and the overall economic benefits are not ideal.
