What measures can be taken to improve the overall efficiency of mulberry fish ponds?

1.Build a mulberry fish pond: the specifications of the newly opened mulberry fish pond require a pond base ratio of 1:

1。The pond should be rectangular, 60 80 meters long or 80 100 meters, 30 or 40 meters wide, deep meters, slope ratio 1 Strengthen the management of the pond base: the growth of the mulberry tree in the pond base, the amount of leaves, and the quality of the leaves directly affect the yield and quality of cocoons, silk and fish.

Therefore, cultivating and managing the pond-based mulberry trees and increasing the leaf production are the keys to improving the overall efficiency of the mulberry fishpond. The high-yield cultivation technology of Tangji mulberry orchard should adhere to the cross measures of "soil modification, more fertilizer, improved seeds, dense planting, and fine management" to achieve the purpose of fast, high-quality and high-yield, so as to achieve the cultivation of mulberry in the current year, the raising of silkworms in the current year, and the benefit of the current year. 3.

Soil modification:. Digging the fish pond makes the original fertile and loose topsoil and tillage layer become the subsoil layer, and the original subsoil layer is filled on the surface of the pond foundation, as the new cultivated soil layer, although the organic matter content has increased, but the reducing substances are also increasing. Therefore, before planting mulberry, all the soil on the pond foundation should be ploughed once, with a depth of 10 15 cm, to enhance the permeability of the soil, and improve the soil water and fertilizer retention capacity.

4.More fertilizer: The principle of increasing the application of organic fertilizer and intercropping green manure should be mastered.

First, it is necessary to apply enough base fertilizer for mulberry planting, apply 100 200 quintals of soil miscellaneous fertilizer mixed with 30 40 kilograms of phosphate fertilizer per mu, and then apply 10 20 quintals of manure and urine, or 150 200 kilograms of cake fertilizer, and cooperate with the application of 25 50 kilograms of lime to improve acidic soil. Second, after the mulberry tree survives and grows new roots, apply a fast-acting nitrogen fertilizer from late April to early May, apply 20 kg of urea or 50 kg of ammonium carbonate per mu, and it is best to apply 50 80 quintals of decaying human feces. Third, the growth and development stage of mulberry requires a silkworm to be raised and fertilized.

And pay attention to reasonable intercropping, a variety of leguminous green manure, timely burial. Fourth, in combination with the clear pond in winter, dig a layer of silt on the foundation. 5.

Improved seeds: Tangji mulberry planting, should be selected high-quality and high-yield grafted mulberry varieties, such as Hu mulberry, Tuantou lotus leaf white and 7920, etc., should also be planted about 15 early and middle mulberry varieties. 6.

Dense planting: The pond gene has been artificially modified to soil, the soil layer is loose, and a shallow ditch can be dug to plant mulberry. Due to the high groundwater level of the pond base, the root distribution of mulberry trees is shallow, so it is suitable for dense planting.

When planting mulberry, the fixed row dense plant is used, and the row spacing of the plant is 33 cm 132 cm or 50 cm 100 cm is good, and the mulberry is planted 1000 1300 plants per mu. The mulberry planting place must be 70 100 cm from the water surface of the fish farming, and the main trunk of the mulberry tree should be 20 30 cm high, and it should be cultivated into a low and medium trunk tree type. 7.

Fine tube: After the pond base is planted, mulberry cultivation, weeding, fertilization, pest control, reasonable felling and other cultivation must be done well to ensure the high and stable yield of the pond base mulberry orchard and improve the leaf quality.

You can strengthen the planting of mulberry trees, but also to ensure the health of mulberry trees, because the leaves of mulberry trees can feed silkworms, silkworm sand can feed fish, that is to say, in the final analysis, only mulberry trees are healthy, fish ponds have better economic benefits!

Scientific management and smooth operation.

The mulberry fishpond is conducive to maintaining the ecological balanceThe mulberry fishpond ecosystem is more complex and perfect, and there are many advantages, the main advantages are: "mulberry mao, silkworm strong, fish hypertrophy; Tang Ran envy fertilizer, good base, silkworm cocoons". This fully demonstrates the interrelationship between the circular production of "mulberry fishponds".

In this circular production system, "mulberry" is the producer, which uses sunlight, water and carbon dioxide to photosynthesize and produce organic matter to produce mulberry leaves. Mulberry leaves are fed to silkworms, so that the nutrients and energy of mulberry leaves are first transferred to silkworms along the food chain, and silkworms are first-class consumers. After the silkworms eat the mulberry leaves, the silkworm sand and silkworm pupae are released and put into the pond as feed for the fish.

In this food chain, fish is a secondary consumer. The microorganisms in the fish pond can decompose fish, algae and various organic substances, so that they can be converted into simple inorganic substances, such as nitrogen, phosphorus, potassium and other elements, mixed in the pond mud, and then restored to mulberry with the pond mud. In this food chain, microorganisms become decomposers and reducers of organic matter.

In the process of planting mulberry, a part of mulberry leaves and dead branches fall to the base or fish pond, and after microbial decomposition, the organic matter is converted into simple inorganic salts, which are released into the soil, and the nutrients of mulberry trees or other crops (vegetables, sugarcane, fruits) are absorbed and utilized, and another new material cycle begins. It can be seen that the model of "Sankey Fishpond" is a complete ecosystem integrating a variety of cycle types

1. The combination of mulberry planting and silkworm raising, fish and pigs, there is a close connection in the production of rolling shirts, and through recycling, the economic benefits of "two benefits, ten times the grain" have been obtained.

2. Plants and animals are mutually nourishing, forming a virtuous circle of mulberry, silkworm, fish and mud that are interdependent and mutually promoting.

3. The pond and the base are reasonably distributed, and the water and land resources are combined. It avoids waterlogging, creates a very ideal ecological environment, obtains ideal economic benefits, and reduces environmental pollution at the same time.

Production method :

Starting from mulberry planting, through silkworm farming and ending in the production cycle of fish farming, it constitutes a close relationship between mulberry, silkworm and fish, forming a relatively complete energy flow system of mulberry planting, mulberry leaf silkworm raising, silkworm cocooning, silkworm sand, silkworm pupa, silk reeling wastewater collapse macro fish farming, fish manure and other mud fertilizer mulberry. In this system, silk is an intermediate product and no longer enters the material cycle.

Fresh fish is the ultimate product, providing people with food. The quality of any production link in the system will also affect other production links. It fully illustrates the connection between the various links in the circular production process of mulberry fish ponds.

The ecological principle of the <> mulberry fish pond is to plant mulberry trees on the ridge or near the pond, raise silkworms with mulberry leaves, use silkworm sand and silkworm pupae as bait for fish, and use pond mud as fertilizer for mulberry trees, so as to form a production structure or production chain of pond ridge mulberry, mulberry leaf silkworm raising, silkworm pupae feeding fish, and pond mud fertilizer mulberry. The significance of the mulberry fishpond is that it plays a role in the symbiotic relationship between material cycle, energy flow and transformation and living organisms in the ecosystem.

First, the principle of mulberry fish pond

1. Mulberry fish pond is a production and operation model that combines mulberry silkworm farming and pond fish farming, and its ecological principle is: planting mulberry trees on the pond ridge or near the pond, disadvantage or loss of mulberry leaves to raise silkworms, silkworm sand, silkworm pupa, etc. as bait for fish, and pond mud as fertilizer for mulberry trees, so as to form a production structure or production chain of pond ridge mulberry, mulberry leaf silkworm raising, silkworm pupae feeding fish, and pond mud fertilizer mulberry. In this way, the two can use each other and promote each other to achieve the effect of taking both fish and silkworms.

2. The significance of mulberry fish pond is to play the symbiotic relationship between the material cycle, energy flow and transformation of the ecosystem and the rental of gods, and it can also promote the mutual circulation of animal and plant resources, which is conducive to maintaining the ecological balance, and is a production mode with very good production effect.

3. When planting mulberry trees by the pond, we must choose saplings with strong growth and strong resistance, and then dig a planting hole of suitable size, prune the branches and leaves of the sapling, and then put it into the hole, and then slowly fill the soil and compact. Finally, it should be covered with a layer of straw, which will help the mulberry tree quickly adapt to the new environment.

Second, the advantages of mulberry fish ponds

1. The proportion of biomass at each trophic level in the food chain inside the mulberry fish pond is very appropriate, and the input and output of material and energy are very balanced, which can promote the recycling of animal and plant resources and maintain ecological balance.

2. Before breeding, it is necessary to choose fish species suitable for breeding in local stagnant ponds, such as catfish, carp, crucian carp, grass carp and other more common fish can be cultivated, and the method of multi-species polyculture is generally adopted, which can play a role in water quality regulation.

Mulberry fish pond is a common fishery farming model in Jianliang. The scale of development of this model is influenced by many factors. Among them, the most important factors are as follows:

1.Land and water resources: Sankey fishponds require a certain amount of land and water resources for fish farming, so these two resources limit the scale of development of Sankey fishponds.

2.Market demand: The scale of development of mulberry fish ponds is also affected by the demand of the city's collapsed state farms. If the market demand increases, the size of the mulberry fish pond will also increase.

3.Technical level: The technical level of the mulberry fish pond affects the development of its scale. With advanced technology, scientific management and efficient breeding, it can improve production.

In short, the development scale of mulberry fish ponds is affected by many factors, and the developers need to consider various factors and formulate corresponding development strategies in order to improve the development efficiency.

The production mode of "mulberry fish pond" is: silkworm sand feeding fish, pond mud fertilizer mulberry, mulberry planting, silkworm raising, and fish farming, forming a virtuous circle of mulberry, silkworm, fish, and mud interdependence and mutual promotion, avoiding waterlogging, creating a very ideal ecological environment, receiving ideal economic benefits, and reducing environmental pollution at the same time

Therefore, the answer is: silkworm sand feeds fish, pond mud fattens mulberry, mulberry planting, silkworm raising, and fish farming are combined to form a virtuous circle of mulberry, silkworm, fish, and mud code chain that is interdependent and mutually reinforcing
