Antifreeze Mechanism of Fish Protein Organic Fertilizer and lts Application on Fruit Trees

Abstract: The problem of fruit tree freezing damage is a big problem that has always plagued fruit farmers. Fruit tree freezing damage directly affects the yield and quality of fruit, and the economic benefits of fruit farmers will also be adversely affected. As a high-quality organic fertilizer, fish protein organic fertilizer has the function of anti-freezing. When it is used in fruit tree fertilization, it can effectively improve the cold resistance of fruit trees and protect the quality of fruit products.

1. Antifreeze mechanism of fish protein

Fish protein organic fertilizer is based on modern biochemical technology, uses fish as raw material. It is a natural organic fertilizer prepared after biochemical reaction extraction. Due to the particularity of its composition, there are more unsaturated fatty acids in the interior. Using these fats, plants can withstand severe cold, and even in cold weather, plants will not be frozen. Moreover, the fish protein organic fertilizer also contains more proline, which plays an effective protective function on the plant cell membrane and prevents it from being damaged. When the alpine and high temperature weather comes, the crops can still grow healthily.

2. Application of fish protein in fruit trees

By applying fish protein fertilizer on apple trees, the most obvious characteristics of fruit trees are that the leaves are wide and thick, and the water is sufficient. Compared with those before fertilization, the thickness, freshness and dry weight of the leaves have increased by 27%, 35% and 26% respectively. The fruit trees basically do not have the phenomenon of peduncles falling off, and the fruit set rate has reached 99%. After the test, other growth indicators of the fruit trees have also been significantly improved, and the fruit trees have reached the qualified standard. Among them, the size of the leaves has increased by 12%, the length of branches has increased by 43%, and the yield of apples per plant has increased by 22%. Most importantly, the freezing injury rate of apples was significantly reduced, the freezing injury of apples decreased by 81%, and the soluble solids of apples increased by 1.3%, which also met the standard of high-quality fruit products.

In summary, after fertilization observation, it is concluded that fish protein organic fertilizer has antifreeze function. The application of fish protein in fruit trees can improve the frost resistance and cold resistance of fruit trees, provide a good growth environment for fruit trees, and reduce the adverse effects of climate, temperature and other factors on fruit trees. Thus, the quality of fruit trees is guaranteed, and the yield and quality of fruit products are guaranteed.
