Identification of the authenticity of hawthorn
genuine work
The dried rhizome of Kaempferia Kaempferia is processed into nearly round or oval slices, with a diameter of1.5 ~ 2cm and a thickness of 2 ~ 6mm. The outer skin at the edge is shriveled, and sometimes root marks, scales and ring marks can be seen, and the appearance is light brown or yellowish brown. The middle of the section is slightly convex, smooth and delicate, white-like and rich in powder; It smells fragrant, slightly like camphor, and tastes spicy, but it is different from ginger.
fake stamp
Bitter hawthorn is similar in size and flake to the genuine product, but its skin is brown; The section is light brown and slightly powdery; Smell it without the aroma of the real thing, and taste bitter. From these three points, we can identify the authenticity of the hawthorn.
Cultivation techniques of Rhizoma Kaempferiae
1.
Choose warm, sunny, wet land, convenient for drainage and irrigation; The soil is better on loose and fertile sandy soil and soil. After the land is deeply ploughed, finely raked and leveled, a high border with a width of 133 cm is opened, about 22,500 grams of compost is applied per hectare, and 600-750 kilograms of oil residue and calcium superphosphate are applied to the border surface, and then the soil is turned again after fertilization, raked and leveled, and it is to be planted after burrowing.
2. Breeding method
Reproduce with tubers. When harvesting, select strong Alpinia officinarum as seed, which is free from pests and diseases and is not damaged by freezing, dry the water vapor on the epidermis, and store it indoors or outdoors. The indoor storage method is: stack dry fine sand and ginger in layers in a dry place. When stacking, spread a layer of sand at the bottom first and then put seed wheat in layers, so that the stacking height is 100 cm; The outdoor storage method is: dig a pit with a width of about 100 cm, a depth of 50 cm, and a length depending on the number of seeds stored. First, put a layer of sand in the pit, and then plant ginger one layer at a time. This is done in turn, with a height of about 34 cm, and cover with fine sand13 ~17 cm.
Step 3 plant
It is best to plant it in the middle of April, and it can be planted by nest planting or horizontal ditch on the compartment, but it is better to cut it by nest. The planted ginger is divided into single branches according to its natural bifurcation. Dig a nest on the compartment according to the row spacing of 27 cm *27 cm, and the depth is about 16 cm. Plant 3 ginger in each nest, and discharge them according to the zigzag pattern. The amount of seeds used is about 3,000 grams per hectare. After planting, apply about 30,000 kilograms of human and animal manure to the nest, and then cover the compartment with soil, with the thickness of 10 cm. Otherwise, cover it with soil.
4. Field management
(1) Drainage and Irrigation The soil should be kept moist after planting, which is conducive to the normal emergence of seedlings and the achievement of Miaoqi and Miao Zhuang. The management should be flexible, so as to irrigate during drought and drain during waterlogging. (2) After weeding seedlings in intertillage, start intertillage weeding, and remove weeds if there are any, so as to keep the field basically free of weeds. Before sealing the bank, you can gently loosen the soil with a small hoe, and be careful not to damage the seedlings, so you can only pull the grass by hand.
(3) Topdressing is generally carried out for three times, the first time is in the middle and late June, when the seedlings are fully grown, and 2250-3000 kg of human and animal manure or urea 150-225 kg is applied per hectare; The second time was conducted before the leaf border was sealed in the middle and late July, and compost18750kg, oil residue 450-600kg and calcium superphosphate 750-1050kg were applied to the border. The method was to compost the above fertilizers, then apply them to the border with a hoe. For the third time, from the end of September to the beginning of 10, the seedlings of Kaempferia kaempferia have been closed, so it is inconvenient to apply dry manure, so we can only apply light human and animal manure water or add a certain amount of fermented oil residue for mixed application. Generally, about 0/5000 kg of human and animal manure water and 450-600 kg of oil residue are applied per hectare.
5. Pest control
(1) Leaf spot occurred in August ~10, and yellow round or oval spots appeared on the leaves, and then the spots dried up into white films or perforations, and the roots were thin or rotten.
Prevention and control methods: Pay attention to soil selection, arrange ditches properly when preparing soil, and drain water in time after rain, which can reduce the occurrence.
(2) From the time of rodent infestation to the time of seedling emergence, voles dig up and steal ginger at night, resulting in lack of plants.
Prevention and control methods: Put rodenticide in the infested areas of field voles to trap and kill them.
(5) The leaves are harvested in Huang Shi in the middle and late February of/kloc-0 in the planting year. Dig up the whole plant, remove the sediment, remove the overground parts and fibrous roots, and all the rest can be processed into commodities except seed. Wash the rhizoma kaempferiae to remove the soil, cut it into ginger slices with a thickness of 0.3-0.5 cm by hand or slicer, and dry it in the sun or smoke it with sulfur 1 day. Generally, the yield of fresh ginger18750 ~ 22500 kg per hectare can reach more than 30000 kg. Dry goods are 3750 ~ 4500 kilograms, and the height can reach more than 6000 kilograms.
Product quality: dry, white, fragrant, free of impurities and mildew, especially white, powdery and strong smell.
