Embodiment Construction

[0012] Rice field culture hybrid lobster of the present invention also needs to pay attention to the following steps:

[0013] (1) Sun-drying: Rice sun-drying should be lightly roasted. The field water cannot be completely drained. The water level should be lowered until the surface of the field is exposed.

[0014] (2) Fertilization of paddy fields: The basal fertilizer of paddy fields should be fully applied, and decomposed organic fertilizer should be applied to achieve the purpose of long-lasting and long-lasting fertility. Bio-compound fertilizers should be applied every 10 kg / mu. It is strictly forbidden to use chemical fertilizers, such as ammonia water and ammonium bicarbonate. Lobsters are very sensitive to pesticides. When it is necessary to apply pesticides to rice, we can properly choose high-efficiency and low-toxic pesticides without pests, and spray rice leaves as much as possible without spraying them into the water.

[0015] (3) Grass planting: transplant aqua...

Abstract

The present invention is technology of cultivating hybrid fresh water crayfish in rice and lotus field. The technology includes selecting rice and lotus field, sterilizing, applying basal fertilizer, transplanting rice or lotus, raising young crayfish, filtering to avoid escape and field management. The present invention has simple method, high crayfish yield, low cost and other advantages.

Description

Technical field: [0001] The invention belongs to the technical field of cultivation, and in particular relates to a freshwater hybrid lobster hatching cultivation technology. Background technique: [0002] As we all know, the existing lobster farming is grown in rivers, lakes and seas, and it is difficult to improve its output and quality to meet people's food needs. People hope to find a technology that can "use" rice fields to widely breed lobsters. . Invention content: [0003] The purpose of the present invention is to provide a kind of hatching culture technique of freshwater hybrid lobster utilizing paddy field cultivation according to the above-mentioned deficiencies. Because hybrid lobster has low requirements on water quality, feed, and field conditions, and there are paddy field cultivation in many areas, the utilization of paddy field is not enough. Plant rice and raise shrimps to increase the economic benefits per unit area of ​​rice fields. Raising freshwater...
