Penaeus vannamei Feeding Techniques

(1) Requirements for feed. The different growth stages of Penaeus vannamei have slightly different food requirements. In the larval stage (within 5cm), the requirement for protein and unsaturated fatty acids is high, and it should reach 35%; In the shrimp stage (5-12cm), protein and unsaturated fatty acids can be reduced accordingly, and the protein can be in 22%; (12-23cm) The requirements for protein and unsaturated fatty acids in foods should be high. Protein should be mentioned as 25%, especially in the period of gonadal development. However, in general, Penaeus vannamei can grow normally with low dietary protein content (20-25%). Now there is already a certain amount of feed for South American white prawns on the market. Moderate food can be. (2) Feeding amount. The amount of bait should be determined according to the weather, survival rate, amount of residual baits, health conditions, water quality environment, shelling, medication, and the amount of biological feed. Under normal circumstances, the survival rate of the shrimp in the pool can be determined according to the following formula: Survival = Average number of traps per net Acquisition area Shrimp pond product K (K is the escape coefficient Depth of water is 1.2-1.5 Water depth is 1.5m 1.3-2.0, when the water depth is 2.0m, it is about 2-3, and there are many empirical algorithms and methods to determine the liveness, which can also be determined by the prey conditions.The following table can be used for reference.(3) Feeding Techniques Feeding Management To be relatively reasonable, it is necessary to ensure that shrimps are eaten and eaten well, but also take into account the breeding environment and cost savings. The techniques for feeding bait are: 1. Adhere to diligent feeding (less than 4 feedings a day); Feed more in the evening and before dawn, feed less under the conditions of the sun; 3. Feed more than 30% of the empty stomach after feeding for 1.5 hours. 4. If the water temperature is lower than 15°C or higher than 32°C Feed less; 5, when the wind and the sun will feed more, heavy storms (7 or more), cold invasion (cooling above 5 °C) when feeding or not feeding; 6, a large number of prawns on the same day less feed, shell 1 Days later, more feeding, 7, more competition in the pool, suitable for more feeding, 8, when the water quality is good, feed more, when the water quality is worse 9, when the pool of biological feed is adequate, it can be fed less.The amount of feed, feed time to be due to the time, due to the flexibility to grasp, the general culture in the early basin-based bait-based, not feeding or less feeding; The basic bait in the pool is basically depleted, and it should be changed to feed with bait. The shrimp in the later period is close to harvesting. In order to promote growth, some fresh shellfish can be fed in appropriate amounts.

Field Management Of Goji Berry

1.Weeding

It is necessary to weed twice a year, people should weed in spring in April and autumn in September, firstly, people should dig the soil with 20cm deep, then people should weed to plant goji berries in wide area, therefore, people weed by machine in modern production, which can not only achieve the purpose of weeding, but also loose the soil to improve the growth environment. In some cases, generally for the goji berries planted in that very year, people can grow some beets or melons among goji berries, which can only be done in the same year.

2.Fertilizer and water management

Goji berries bear fruits in summer and autumn, during planting, the management of water and fertilizer is very important, which can directly improve the yield and the quality of fruit. During the fertilizer spraying, the fertilizer cannot be sprayed on leaves, during fertilizing, people should cover the fertilizers with soil and water them, people always fertilize in autumn and choose the amount of fertilizer by planting area.

3.Pruning

Regular pruning on goji berry plants can ensure better absorption of nutrients and faster growth, generally speaking, the yield will be higher with time goes by, the plants grow faster year by year, people should choose the brunches grown in second year to prune. At the same time, during pruning, people should shape and prune in a scientific way to ensure the branches can be exposed to the sunshine and have better breathing, also to let the branches grow faster, so as to achieve the goal of high yield, and ensure the stable development of branches, improve fruit quality.

4.Harvesting and processing

1) As for drying of goji berry, goji berries should be poured into lye and soaked for a time, then coupled with aqueous alkali which is mixed with water and dietary alkali with the ratio of 10:1, and the put out goji berries to rinse out wax on the surface and dry them in a short time, usually for 5 days. Also, after soaked in aqueous alkali, goji berries can be protected if they have some fruit wounds, the sugar in the fruit can be avoided to evaporate and the fruit color can be maintained.

2) Reasonable drying: goji berries should be dried on the screen, goji berries can not be exposed to too bright sunshine and can not be touched and stirred to avoid damage.

3) Processing: the root of goji berry is also a good medicine, so people should dig out the roots out at the beginning of spring to separate the root and skin and dry them after shredding.

4) Fruit drying: fruit drying can be divided into three stages, the standard of judging final drying is to hold goji berries in hand and observe the dispersed state.

Above all, through a series of measures, with time goes by, people can obtain a good harvest and have high yield and quality orchard, by the way, there are still some technical promotion space that should be found by staff to maintain high yield and quality in the cultivation.
