A method for stocking carp in rice fields with full mechanized operation

Abstract

The invention discloses a method for breeding cyprinoid in a fully-mechanized operation rice field. The method comprises the following steps: disinfecting the rice field and applying a base fertilizer; forming a water inlet and a water outlet of the rice field and arranging an escaping-proof instrument; providing a fish pit and a harvest basin after rice transplanting for 2-3 days; mounting a sterilizing lamp; setting a natural enemy-proof measure; breeding fish fries; managing at a large field period; draining the rice field and harvesting cyprinoid. By adopting the method, dual harvest of cyprinoid and rice can be realized, and the overall economic benefit of an enterprise in rice planting is increased; breeding of cyprinoid contributes to green and organic rice production, the use of chemical fertilizers and pesticides is reduced, and the activities of cyprinoid also contribute to production of rice; cyprinoid eats weed sprout in the rice field continuously, plays a good role in controlling easy growth of weed at the early stage of the mechanical transplanting rice field, and eats weed seeds to reduce future growth of weed in the cyprinoid breeding rice field; fishes can eat a large quantity of imagoes and eggs, even sclerotium in the rice field, so that harm of diseases and pests to the growth and development of the rice can be reduced effectively, and a good ecological benefit is achieved.

Description

technical field [0001] The invention belongs to the technical field of carp breeding, and in particular relates to a method for stocking carp in paddy fields with full mechanized operation. Background technique [0002] Raising carp in paddy fields is the most successful breeding project in hilly and mountainous areas and even high mountainous areas where water sources are guaranteed. Farmers manually transplant rice seedlings and harvest rice fields by hand. Traditionally stocking carp and fish fry in rice fields can increase the income of commercial carp by more than 600 yuan / mu, which is very important for increasing farmers’ income. The effect is obvious. With the rapid aging of the rural labor force in our area, the rural labor force is rapidly decreasing, and it is an inevitable road for rice production to rapidly move towards full mechanization and enterprise. Raising carp in rice fields with full mechanized operation is of great significance for improving the overal...

Problems solved by technology

The bottleneck in realizing the mechanization of rice production is the cultivation of machine-transplanted rice seedlings, that is to say, the lack of mechanized rice seedling transplanting cannot be regarded as full-scale mechanized production.
