Method for increasing yield of Chinese gallnut through forest moss planting, aphid breeding and natural migratory flight

Abstract

The invention discloses a method for increasing the yield of Chinese gallnut through forest moss planting, aphid breeding and natural migratory flight. The aphids are bred by artificially planting the moss in the forest, the natural growth characteristics of moss are combined, and the requirement for agricultural production intensive management is met. On one hand, the safe and effective living environment can be provided for the overwintering aphids, the survival rate of the overwintering aphids is improved, the number of spring migratory aphids on the tree next year and the number of fundatrixes in the next year are increased, and therefore the yield of the Chinese gallnuts is improved. A container is used for containing sandy and stony soil, the container is covered by the soil, the moss is planted on the container, and the four side walls on the lower portion of a container opening are provided with drainage holes. When rainwater is large, the water can overflow through the drainage holes, and water cannot be accumulated at moss branches. When rainfall is less or drought occurs, a certain amount of water can be kept at the bottom of the container and can rise to the soil layer through the capillarity action, the growth requirement of the moss branches can be continuously met, the survival rate of the aphids on the moss can be improved, and the excessive dependence of the schlechtendalia chinensis migratory flight and tree attaching on the weather is reduced. Meanwhile, surrounding weeds can be effectively prevented from invading through the container, the growth space of the moss branches is kept, the service life of the moss branches is prolonged, each moss block can be continuously used for 3-4 years, and production cost is reduced.

Description

technical field [0001] The invention belongs to the cultivation technology of economic forests, and in particular relates to a method for naturally cultivating and migrating galla aphids in the field to increase galla production. 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 lar...

Problems solved by technology

Galla aphids live in different hosts throughout their life cycles. They will experience aphid types such as wingless stem females, winged stem females, overwintering nymphs, winged migratory aphids (sexual females), male and female aphids, and dry females. and moss hosts alternately change their lives. Among them, due to the protection of galls on trees, the survival rate is higher, but on moss hosts, there are only wax filaments, and the protection ability is limited, and it has to go through autumn, winter and spring. Due to the temperature and humidity changes, the survival rate is very low. Some research data show that: from autumn migratory aphids to dry mothers, the average survival rate under natural conditions is less than 5%.

This method can significantly increase the yield of beizi, but there are also the following problems. First, the production process includes collection and planting of moss seeds, scattering of aphids in autumn, management of aphids, collection of aphids in spring, bagging and hanging. , the time is long, the production process is relatively complicated, the technical requirements are high, farmers are difficult to master, and the production cost is high. The time is highly concentrated, resulting in insect harvesting and bag hanging often depending on the weather conditions of those days, and the effect of multiplication is greatly affected by climate change, making it difficult to achieve stable production

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