1. Planting method: respectively bag the seeds of Rhus verniciflua, Populus davidiana and soak them in running water, then soak them in warm water at about 50℃ for 24 hours, dry them and sow them. Before sowing, the soil should be leveled and raked, and the seeds should be evenly scattered in the ditch and covered with soil for transplanting in winter or next spring. After that, we should do a good job in topping and pruning, protecting vegetation, preventing defoliation in summer, and controlling pests and diseases. 2. Precautions: The growth of gallnut must meet the three conditions of gall aphid, summer host tree and winter host moss. When breeding, it is necessary to determine what kind of moss is the overwintering host of aphids in the planting area before collecting moss.

First, the planting method of gallnut and matters needing attention

1, planting environment

Galla chinensis is not strict with soil, and all the soil that can grow crops can be used to grow Galla chinensis. It likes warm and humid climate, and can resist certain cold and drought, barrenness and moisture, so there should be no relatively low-lying places for planting.

2. Planting method

The seeds of Rhus sumac, Populus deltoides and Populus deltoides were bagged respectively, and then soaked in running water for 6-7 days. After taking out, the residual pulp and wax layer were rubbed off by hands, and then soaked in warm water at about 50℃ for 24 hours, and then dried to sow. Before sowing, the soil should be whole, the rake should be flat and thin, and shallow flat ditches should be drilled at a spacing of 30-40 cm. Finally, the seeds are evenly scattered in the ditch and covered with soil, which can be transplanted in winter or the next spring.

3. Tian Tuan management

(1) Topping and pruning: After the gallnut is planted, the tree vigor should be controlled in time, the terminal buds of young trees should be removed, and the tree height should be controlled at about 2 meters. At the same time, it is necessary to prune branches reasonably, mainly pruning diseased branches, dead branches, dense branches and overgrown branches.

(2) Vegetation protection: In order to avoid destroying the growing environment, it is necessary to protect vegetation and destroy the growing conditions of overwintering hosts. Galla chinensis does not need intertillage weeding, but only needs to prune shrubs and tall grass that grow too high, so the yield and quality will be better.

(3) Anti-defoliation in summer: In addition to topping and pruning, defoliation and nutrient transport can be controlled by cutting leaves of gallnut fruit trees.

(4) Pest control: The main diseases of gallnut are anthracnose and black spot, which can be controlled by mancozeb, and carbendazim and thiophanate-methyl are also effective. The main pests of gallnut are Euonymus spinosus, elephant with broad shoulders, midge of tree, weevil and so on. The main control method is killing.

(5) stocking aphids migrating in autumn: hanging aphids, collecting mature aphids that have not exploded, hanging them on the branches of aphids or putting them on the moss under the forest, so that they naturally burst and release aphids; Collect insects and put aphids, collect mature plovers, put them in wooden boxes or urns, overlap them, cover them with a layer of pine needles or straw and a layer of plovers tightly; Artificial rearing of insects means that aphids migrating in autumn will give birth to overwintering young aphids on the moss cultivated in the insect rearing room. By the next spring, aphids migrating in spring will be collected artificially and placed on double trees, or naturally fly from the insect rearing room to double forests.

4. Harvest and processing

The harvesting time of gallnut is when the gallnut has grown up and the aphids inside have not broken through the gallbladder wall, probably in late summer and early autumn. At this time, the gallnut looks like a full olive, with brown or yellow appearance, a small amount of gray silk hairs, a skin wall thickness of about 1cm, and gray aphids with wings or wings are hidden inside. Blanch it with boiling water in time when it is fresh. After picking, some large and strong diploids should be left as insect species in the coming year.

5. Preventive measures

To plant gallnut, three conditions must be met at the same time: gall aphid, summer host tree and winter host moss, that is to say, the growth of these aphids and parasitic plants should be paid attention to in the planting area, so that gallnut can be planted successfully. It should also be noted that gallnut aphids are selective to overwintering hosts, and it is necessary to determine what kind of moss is the overwintering host of aphids in planting areas before collecting moss for reproduction.

Second, is gallnut the same as Schisandra chinensis?

1, Galla chinensis and Schisandra chinensis are two different plants. Among them, gallnut is gall on the leaves of Rhus verniciflua, Populus deltoides or Populus deltoides, which is mainly parasitic by gallnut aphids; Schisandra chinensis is a dried and mature fruit of Schisandra chinensis of Magnoliaceae.

2. The scientific name of gallnut, also known as Baicongcang, Baiyao Decoction and Xunzi, is widely used as Chinese medicine. Schisandra chinensis, divided into Schisandra chinensis and Schisandra chinensis, Schisandra chinensis is better than Schisandra chinensis.
