Problems solved by technology

Rice that has had its husk and bran removed is called polished rice or white rice; there have been examples of polyculture of lobsters during the rice planting period, but there are still some problems that need to be solved. One of the key problems is that in the rice planting period, some poisonous Killing pesticides, which obviously have a certain impact on the growth of crayfish

Embodiment 1

[0019] Embodiment 1, a kind of method of polyculture lobster during rice planting period, specifically:

[0020] (1) Select the rice seeds produced in the previous year, spread them on the screen in a single layer, and set the ozone generator directly above the screen 10-12cm away. The outlet of the ozone generator is facing the rice seeds, and the ozone generated by the ozone generator will The output is 40g / h, and the processing time is 48 minutes;

[0021] (2) Sow the treated rice seeds in the black soil in the seedling pot. During the seedling raising period, after the rice seedlings emerge, pour 2000 times of phenylurea into the black soil to keep the black soil humidity at 80%;

[0022] (3) Transplant the rice seedlings treated for 38 days into the paddy field;

[0023] (4) The selected shrimp seedlings with a size of 0.5-0.7cm are sent to the culture pond for preliminary cultivation. The cultivation time is 10 days. The cultivation method adopts dry method and wet meth...

[0026] Embodiment 2, a kind of method of polyculture lobster during rice planting period, specifically:

[0027] (1) Select the rice seeds produced in the previous year, spread them on the screen in a single layer, and set the ozone generator directly above the screen 10-12cm away. The outlet of the ozone generator is facing the rice seeds, and the ozone generated by the ozone generator will The output is 41g / h, and the processing time is 49 minutes;

[0028] (2) Sow the treated rice seeds in the black soil in the seedling pot. During the seedling raising period, after the rice seedlings emerge, pour 2100 times of phenylurea into the black soil to keep the black soil humidity at 81%;

[0029] (3) Transplant the rice seedlings treated for 39 days into the paddy field;

[0030] (4) Select the shrimp seedlings with a size of 0.5-0.7cm and send them to the culture pond for preliminary cultivation. The cultivation time is 12 days. The cultivation method adopts dry and wet cycle cu...

Embodiment 3

[0033] Embodiment 3, a kind of method of polyculture lobster during rice planting period, specifically:

[0034] (1) Select the rice seeds produced in the previous year, spread them on the screen in a single layer, and set the ozone generator directly above the screen 10-12cm away. The outlet of the ozone generator is facing the rice seeds, and the ozone generated by the ozone generator will The output is 42g / h, and the processing time is 50 minutes;

[0035] (2) Sow the treated rice seeds in the black soil in the seedling pot. During the seedling raising period, after the rice seedlings emerge, pour 2200 times of phenylurea into the black soil to keep the black soil humidity at 82%;

[0036] (3) Transplant the rice seedlings treated for 40 days into the paddy field;

[0037] (4) The selected shrimp seedlings with a size of 0.7cm are sent to the culture pond for preliminary cultivation. The cultivation time is 13 days. The cultivation method adopts dry method and wet method c...

Abstract

The invention belongs to the technical field of aquaculture and particularly relates to a method for polyculture of lobsters in a rice planting season. Particularly, rice seeds are selected, are subjected to ozone disinfection and then are sown in black soil in a seedling culture basin; during a seedling culture period, after rice seedlings emerge, 2000-2200-fold liquid of phenylurea is poured into the black soil to maintain the black soil humidity at 80-82%, the rice seedlings obtained by seedling culture are transplanted into the paddy fields; young lobsters are subjected to sequential circulation and alternation through dry method culture and wet method culture and then are placed in the paddy fields; and after the stocking, the lobsters are fed once every 5 days. The lobsters are subjected to polyculture in a rice planting pond, not only can the planting and culture cost be reduced, but also the planting and culture earnings are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for polyculture of lobsters during the rice planting period. Background technique [0002] Rice is one of the main food crops in my country. Nearly half of the world's population, including almost the entire population of East Asia and Southeast Asia, feed on rice. Rice is grown on flooded lands in coastal plains, tidal deltas and river basins in tropical, semi-tropical and temperate regions. The harvested grains, called paddy rice, have a husk that is often removed during milling along with the bran layer, sometimes with a thin layer of dextrose and talc to give the grains a glossy finish. Rice that only removes the husk during milling is called brown rice, which is rich in starch, contains about 8% protein and a small amount of fat, and contains thiamin, niacin, riboflavin, iron and calcium. Rice that has had its husk and bran removed is called polish...
