The survival rate and the opening rate of the bottom box of the seedlings have been puzzling the farmers. How to improve the survival rate and the opening ratio is an urgent problem to be solved in the industry.
Survival rate and opening rate and water quality, climate, time of unloading, quality of seedlings, stocking, transport, grading, aquatic plants in cages, water body maintenance, carcass maintenance, tame concept, tame food, check box and food table There is a big relationship. The following describes the work that the seedlings should pay attention to before stocking and when they are stocked.
1. Water quality Dianchi water quality must be tender, live, and cool. Oxygen content exceeds 5 mg/l. The pH is between 7.2 and 7.6. Water toxic ammonia does not exceed 0.02 mg/l, hydrogen sulfide does not exceed 0.1 mg/l, and nitrite does not exceed 0.05 mg/l. Water quality testing must be performed before going down. If it exceeds the limit, it must be adjusted. Pool water depth is controlled at about 40 cm.
2. The water temperature of the next box is stable at 25°C. The temperature difference between day and night does not exceed 5°C. Staggering the spawning and spawning period of the scutellaria baicalensis, the maximum water temperature does not exceed 34°C, and the above conditions can reach the seedlings.
3, climate seedlings before close to pay close attention to climate change, it is best to order long-term weather forecast messages, there is a sunny day before the next box, after the box to ensure there are four sunny days. The temperature difference between day and night does not exceed 5°C.
4. The revolutionary grass in the aquatic cages of the cages must be lush and the seedlings in the lower box have a good environment for inhabitation, so as to reduce the occurrence of stress response to jaundice. The revolutionary grass is best mixed with 5% oil grass.
5. The quality of seedling quality seedlings has a lot to do with fishing methods, seed sources, holding time, holding methods, and transportation methods. Be sure to investigate clearly when purchasing. Seeds are best in their own land. The best choice for field seedlings is to have a close geographical environment. Seedlings must be vibrated (electrolyzed seedlings that have been soaked with electrolytes for a period of time. The vigor is particularly good for a period of time. This kind of seedlings is an illusion, and it must be remembered that no use is needed). You do not need to keep mucus in your hands. Head "less (dizziness, brain tissue due to anoxia and necrosis, irreversible damage.) Do not stun when coma, it is best to use a net to knock off the surface jaundice. Correctly recognizing the mountain bar, the hill bar is more difficult to discern on the appearance, you can see the degree of fullness of the muscle, the seedlings in the lake area are relatively fat, and the bar is thinner.
6. The seedlings of the temporary seedlings must be smooth, otherwise it is very easy to scratch the callus and make the seedlings sticky. Seed conservation can not use well water, tap water, and contaminated water, it is best to choose the more clear water in the natural environment. The temperature difference between the new water added should not exceed 2°C, the ratio of fish to water should not be less than 1:2, the water should be changed at least four times a day, and the time of raising should not exceed four days.
7. Seedlings for transporting seeds should be light, fast, and good during transportation. The ratio of fish and water is listed as a strong recommendation of 1:2 or more. Povidone iodine must be used for water maintenance during transportation. The dosage is 6 drops/100 kg (fish + water). Seedlings should not be transported as long as possible and must be transported over long distances. The time should not exceed 10 hours.
8. The seedlings brought back from the lower box should be adjusted to the water temperature and slowly injected into the water in the Dianchi Lake so that the temperature of the seedlings and the water temperature in the Dianchi Lake will be the same. Seedlings can be divided into three grades, preferably four grades, must be lighter, faster, better, and accurate when grading, shortening the time to choose the seedlings as much as possible, knocking out dizzy heads and traumatic seedlings. If the medicine bath is transported, no medicine bath is required. Instead of the electrolytic multidimensional medicine bath, the electrolysis multidimensional can only activate the body potential for a short time, which will reduce the physical fitness of the seedlings and reduce the immunity. At the same time, attention should be paid to the delivery record.

Nuts can generally be divided into two types: one is seeds, such as sunflower seeds, pumpkin seeds, peanuts, etc.; the other is tree nuts, such as pistachios, hazelnuts, cashews, walnuts, pine nuts, walnuts, chestnuts, almonds. And the macadamia and pecans that have been very hot in the past two years. These nut foods contain more protein, calcium and a variety of vitamins, which can provide the body with a variety of nutrients needed by the brain and body.
In general, a nut is a closed fruit classification of a nutrient-covered woody or leathery hard shell. The skin is hard and contains one or more seeds. It includes two types of tree nuts and fruit seeds, walnuts, chestnuts, pistachios, almonds, etc., melon seeds, which belong to the fruit seed class.
