Method for improving yield of chinensis gallnuts by adjusting occurrence time of stem mothers by using accumulated temperature

Abstract

The invention discloses a method for improving yield of chinensis gallnuts by adjusting occurrence time of stem mothers by using accumulated temperature. According to the biological characteristic of chinensis gallnut aphides, a gall formation mechanism and a growth rule of a host tree, galla chinesis aphids are cultured in land blocks of different altitudes or collected spring migrant aphids arestored at places of different altitudes by using accumulated temperature difference of different altitudes to adjust progress of the stem mothers produced by sexuales, so that the occurrence of the stem mothers forms time difference and is increased from original one-time on-tree gallnut formation to two-time on-tree gallnut formation, the stem mothers form gallnuts on different leaves, and further the number of gallnut formation leaves is increased, and the gallnut yield is increased. The method has the characteristics of scientific and rational properties, high operability, obvious production increase effect, high benefit and the like; the gallnut yield can be scientifically and efficiently improved; the gallnut formation potential of a gallnut forest is fully utilized; and the method is suitable for large-area promotion and application.

Description

technical field [0001] The invention belongs to a method for cultivating insects, and in particular relates to a method for increasing gallnut yield by using accumulated temperature to adjust the emergence time of dry mothers. Background technique [0002] Gallnut is a general term for various galls formed by certain aphids of the family Aphididae parasitizing on the leaves of Salmonella, Red Bran Populus, and Green Bran Poplar, stimulating the proliferation and expansion of leaf tissue cells. It is an important forest special product in my country and Export foreign exchange earning commodities. Gallnut is not only an important traditional Chinese medicine, but also the main raw material for the production of chemical products such as tannic acid, gallic acid and pyrogallic acid. It is widely used in other industries. Chinese gallnut production accounts for more than 95% of the world's total production. It is famous for its high tannic acid content, high quality and large ...

Problems solved by technology

This method can significantly improve the yield of beizi, but there are also the following problems. One is that the time for the dry mother to go up the tree is only once, and a large number of dry mothers are concentrated on the adjacent compound leaves to feed, generally only in 1-4 leaves. Double seeds are formed on the compound leaves; the second is that the time for the dry mother to climb the tree is too concentrated, and the temperature in early spring is unstable. If there is a drastic change in temperature, it will cause a large number of dry mothers to die, resulting in reduced or even no harvest, making it difficult to achieve high and stable yields

This not only affects the economic benefits of Beilin, but also restricts the further popularization and application of gallnut artificial cultivation technology
