Gall nut cultivation

Gall nut cultivation

Galla chinensis is a dry worm that is formed on the leaves of arboreal plants such as Rhus chinensis, and is an important Chinese medicinal material and industrial raw material. It is widely used in medicine, chemical engineering, petroleum, metallurgy, construction and other fields. High economic value. Now its artificial production technology is introduced as follows:
? 1 Cultivation of rhodamine
Rhus chinensis is the main parasite wood of gall gall aphids. There are two methods for its cultivation:
1.1 seedlings transplanting: with 40 ~ 50 °C warm water into the grass ash into a paste, rinse the seeds of salt skin. Then mix the water with 10% lime water and mix well. Put the seeds in, soak them for 3 to 5 days and spread them on the pot. Cover the grass curtains and pour the water once a day until the seeds are white. The time is generally from March to April, with a seed quantity of 12 kg per 667 square meters. Seeds are evenly spread on the seedbed and fine sand is added to cover the seeds. The thickness of seeds is not suitable. Then covered with straw or pine needles, chaff, and then spraying manure water until the wet seedbed. Before the seedlings are excavated, they are often watered to keep the seedbeds moist. After a large number of seedlings have been unearthed, the coverings are removed on cloudy days. To cultivate healthy seedlings and improve the survival rate of transplanting.
1.2 Root propagation: The root of old Saussurea vulgaris is excavated, cut into 33cm long sections, and the cut tree roots are planted and the roots are exposed to the ground at 10 to 13 cm. This method has a high survival rate and rapid growth. It can be forested within 2 to 3 years.
2 Lightning cultivation
Lanterns are the wintering hosts of gall and are mostly distributed along the shady, wet side of the ditch. Artificial light bulbs are used to select ample groundwater sources, and it is better to place them north and back. In the spring, the collected lanterns were placed in a well-grounded area. Keep moist after planting, pay attention to watering during drought, and often clean the surface of debris and other debris. Under normal circumstances, every 667m2 of Yanfumulin has 1~3m2 lanterns.
3 artificial reproduction of the angle
Angular folds breed 2 or 3 generations in 1 year. When matured, it bursts in certain areas. At this time, the size of the locust has grown into a winged type (called the autumn migration cricket). This winged locust flew out of the bursting group and flew over the winter to raise the lamp. The wintering larvae emerged into the winged type (known as the spring migration cricket) in the next year, and they also bleed on the linalwood to form gall times. Cycle back and forth to continue their descendants. Artificially introduced seed oysters, each 667m2 salt seedlings can be seeded and weighed 1 to 1.5kg. The artificial propagation method is as follows:
3.1 Inoculation and harvesting for autumn harvesting: When the greens turn yellow from green to unbroken, take several times and then place them in moisturized and ventilated containers, such as cardboard boxes and wooden boxes. It stayed around 90%, causing it to break naturally in the container, allowing winged autumn migration to fly out. This kind of use of container moisturizing species, can be placed in the forest to spread, but also transported to other places introduced. When the larvae start to multiply in the container, they will be inoculated to the overwintering host lantern in the autumn, and the offspring will be able to reproduce. After the emergence of the larvae, it will fly to the knot on the next day. It is worth noting that it is best to make the larvae have a layer of white wax powder in the container body (1 level 7 to 10 days), and then put it on the host overwintering, such inoculation, introduced more successful.
3.2 Artificial protection for spring migration and sex lice: In the spring, wintering plagues are feathered into winged spring migration lice, which fly from lanterns to chinks and begin to reproduce (female and male). After sexual mating, the wingless dry mother was born. Due to the heavy rainfall in spring and the damage to pests, the loss of sex lice is large. For this reason, artificial conserving defects must be used. The method is to collect the spring trout on the tree and place it in a box or wooden box with a vent and ventilation, and put it in a dark place to let it produce dry maternal mating in the box (about 1 month). The carton or wooden box was hung from the budding rhododendron branches and allowed the dry mother to crawl out of the tree. This kind of use of non-fed sex protection is the most effective protection measure.
3.3 Multiple times of transport and protection of overwintering cubs: The protection and transport success of the multiple times depends on the moisturizing and ventilation of the container. The humidity of the container should always be maintained at about 90%. After the wintering cubs are on the tree, avoid direct rains. Can be covered with straw in the early stage of inoculation, and use plastic sheeting in a place where it is exposed to direct sunlight to protect the early overwintering cubs. After the wax balls are formed by the cubs, the coverings are left to leave for natural wintering.
4 Gallic Harvesting Processing
The gallic grain is harvested in late summer and early autumn. It is best when gall has grown and the locust inside has not yet crossed the wall. At this time, gallnuts resemble full-bodied olives with a brownish or yellow appearance with a small amount of gray, white hairy hair, a wall thickness of about 1 cm, and a gray worm with winged or winged buds. The fresh picked times should be scalded with boiling water in time. When the fire is large, water is high, and the water boils, doubly and rapidly scald. When the surface of the gallnut turns from yellow brown to gray, remove and dry it immediately. The moisture content of the finished product does not exceed 14%, and the shell-like substance is hard and brittle, and the hand pressure can be broken into pieces to be sold.
