Seedlings feeding is an important operation link in the cultivation of seedlings. In the past, we used to soak seedlings in pots for three hours with 3% pulp slurry. The purpose was to allow the seedlings to devour the smell of feed and scent feeds before stocking for rapid identification of feeds after stocking. Eat. However, after several years of practice, this method of eating has been found to have more disadvantages. One is that the feed slurry is not swallowed due to discomfort. The second is that high-density soaking in the slurry for a long time will not only cause the seedlings to scratch each other, for example, the slurry will be slightly concentrated, and the slurry will also block the nostrils of the seedlings and cause the seedlings to suffocate. The third is that in this open food operation, there was a once-injury link in which the carcass was artificially damaged. Therefore, the good or bad work done by the seedlings not only affects the survival and growth of the seedlings, but also results in a large number of deaths. For instance, in May of this year, Shaoxing Yiyechang Farm in the plastic pot soaked the high-density seedlings with high-density slurry for 5 hours and caused serious accidents of more than 2,000 seedlings to die. To this end, introduce the improved method of eating, for reference applications.
First of all, 7 days before stocking, the pool water was injected into the standard water level and fertilized. The standard of the fertilizer water is gray or light green (more of the larvae eat in this water) and the transparency is less than 20 cm. PH7-8 . The juveniles are hatched for 24 hours and then sterilized with 2% saline for 20 minutes and directly stocked in the pond. After stocking, sprinkle a pacifier soft pellet feed with a weight of 8% on the feed plate in the tank, and sprinkle a little 1% of feed slurry around the feed plate. This kind of direct stocking and eating method not only adapts the seedlings quickly but also eats well, and the survival rate is greatly improved.
Carbomer is an acrylic resin obtained by cross-linking pentaerythritol with acrylic acid. It is a very important rheological regulator. After neutralization, carbomer is an excellent gel matrix, which has important applications such as thickening suspension. According to the dry product calculation, including carboxylic acid group (-cooh) should be 56.0 % ~ 68.0%.
Common carbopol series include: Carbopol 940, 941, 934, 1342, 980, ETD 2020, AQUA sf-1, Ultrez 21, Ultrez 20, etc.
