Description

Ecological co-culture method for rice and shrimp
Technical Field
The invention relates to the field of crayfish breeding, in particular to a rice and shrimp ecological co-breeding method.
Background
The crayfish has the advantages of fast breeding, short breeding period, delicious meat, rich nutrition, large market demand, wide development prospect and high economic benefit, and is widely used in fresh water ponds in China. However, the quality of the wild crayfish is seriously influenced due to serious water pollution; meanwhile, over-fishing of wild resources and laggard artificial breeding technologies cause germplasm resource degradation and yield reduction. In order to meet market demands, more and more people begin to try ecological breeding, but the existing paddy field breeding method and mode are not proper, so that the produced crayfishes generally have smaller individuals, poorer colors and more diseases, the survival rate and the yield of the crayfishes are affected, and farmers cannot obtain corresponding economic benefits.

(4) And (3) putting the shrimp larvae: in 3-4 middle-ten days, putting high-quality shrimp seedlings into the shrimp ditches and the rice fields, putting 40-60 jin/mu, feeding 60-120 jin/jin of the shrimp seedlings, wherein the ratio of male and female is 3:1, feeding artificial compound feed according to 4-6% of the weight of the shrimp seedlings every day, feeding for the first time at 5-7 o 'clock in the morning, wherein the feeding amount accounts for 30% of the total daily feeding amount, and feeding for the second time at 6-7 o' clock in the afternoon, and the feeding amount accounts for 70% of the total daily feeding amount.
(5) Rice and shrimp joint cropping: in the late 6 th month, the water plants in the rice field are ploughed as green manure, and 700kg of high-quality organic fertilizer is applied to each mu of rice field 7 days before transplanting of the seedlings and the rice; seedling planting density: the row spacing is 30-40cm, and the plant spacing is 25 cm; the rice planting density is 1.5 ten thousand holes/mu; performing shallow water service irrigation on seedlings and rice; after the seedlings turn green, soaking the shrimp ditches in water to enable the shrimp seedlings to enter the rice field for breeding, and appropriately supplementing the shrimp seedlings.
(6) And (3) putting the second shrimp larvae: harvesting rice, then putting shrimp seeds in the second season, wherein the shrimp seeds are 60-100 catties/catty, the stocking density is 30-40 catties/mu, feeding artificial compound feed according to 2-3% of the weight of the crayfish every day, feeding for the first time at 5-7 am, wherein the feeding amount accounts for 30% of the total daily feeding amount, and feeding for the second time at 6-7 pm, and the feeding amount accounts for 70% of the total daily feeding amount.
(7) And harvesting the second-season adult shrimps.
The invention has the beneficial effects that: by adopting the method, finished shrimps and rice in two seasons can be harvested every year, and continuous shrimp and rice cropping and shrimp and rice cropping are organically combined; the artificial compound feed is used in different growth stages, so that the requirement of crayfish on nutrient substances in the rapid growth stage is met, the utilization efficiency of nutrient components of the feed is improved, and the pollution of residual feed and excrement to the culture water body is reduced; the rice planting method has the advantages that the rice planting method is used for planting the crayfishes in a row-by-row and empty-by-row mode, sufficient space and places are provided for the crayfishes to enter the rice field to move, forage and eliminate weeds and pests, marginal effects are fully utilized, the growth of the rice field is facilitated, the pesticide consumption of the rice field is reduced, the planting cost is reduced, and green rice is produced; meanwhile, after the crayfishes are caught, the metabolic products of the crayfishes add organic fertilizers for the rice production, so that rich organic fertilizers can be provided for the rice growth, the use amount of chemical fertilizers and pesticides in the rice planting process is reduced, the growth is mutually promoted, meanwhile, the space of a rice field is effectively utilized, and in the aspect of water quality maintenance, organic components in soil and feed are decomposed into ammonia, so that the content of ammonia nitrogen in a water body is increased, and the water quality is easily eutrophicated; the crayfishes bred by the method have the advantages of quick growth, regular specification, no influence on normal production of rice, dual purposes in one field and great improvement on income.
