Composite planting and cultivating method for rice, procambarus clarkii and soft-shelled turtle

Abstract

The invention relates to a composite planting and cultivating method for rice, procambarus clarkii and soft-shelled turtle, comprising the following seven steps: neatening the preliminary rice field; catching the procambarus clarkii of the last year; catching the soft-shelled turtle of the last year; putting and cultivating the soft-shelled turtle of the year; seeding paddy rice; cultivating the procambarus clarkia of the year; and harvesting the paddy rice. In the invention, a planting and cultivating region is constructed by excavating ditches in a paddy rice field; after harvesting the paddy rice, the zooplankton in the water cultivated through straw return is used as the bait of crayfish; the growth and reproduction of the crayfish are guaranteed by combining the ditches with the paddy rice field; the crayfish is capable of eating a part of the insect pest of the rice so as to guarantee the growth of the paddy rice; the physique of the turtle is guaranteed through eating fresh crayfish; the excretion of the crayfish and the turtle is decomposed through micro-organism preparation, is changed into nutrient substance and is absorbed by the paddy rice; and since the crayfish is high sensitive to chemical pesticide, the use of the chemical pesticide under the production mode in the invention can be eliminated, and the safe agricultural product is produced.

Description

technical field [0001] The invention relates to a planting and cultivating method of grains and freshwater aquatic products, in particular to a combined planting and cultivating method of rice, procambarus graminis and soft-shelled turtle. Background technique [0002] Paddy rice (Oryza) is an annual gramineous plant. The fruit of rice is paddy rice, which is called rice or rice after husk. Nearly half of the world's population, including almost all of East and Southeast Asia, eat rice. It is widely planted in our country. During the planting process, ~quantity of chemical fertilizers and pesticides are applied. [0003] The scientific name of crayfish is Procambarus clarkii (Procambarus clarkii), which is a kind of freshwater shrimp. In the 19th century, some countries in Europe and the United States began to develop and utilize Procambarus clarkii. artificial breeding. Especially in the United States, the aquaculture output of Procambarus clarkii accounts for more than...
