The wormwood has the functions of warming, dehumidifying, dispelling cold, stopping bleeding, etc. The medicinal value is safe. Except for the arid and alpine regions, other places are planted. Of course, wormwood can be used only for medicinal purposes. There are more and more uses in building materials and home textiles, which has led to the inability of wild wormwood to meet the growing demand. The artificial cultivation of wormwood has also developed rapidly. Therefore, today Xiaobian says that the artificial cultivation technology of wormwood is standardized.
1 Site preparation
1.1 Site selection
Ai Cao Xiguang is drought-tolerant and cold-resistant, and has low requirements on soil. However, it is better to use neutral soil with sufficient light and good soil permeability. The surrounding land should be clean and free of dust, and there is no residential sewage nearby. Industrial water pollution, where the air quality meets the requirements of the national standard GB 3059-2012, can choose the cultivation of wasteland, roadside, riverside and hillside in the hilly area.
1.2 Site preparation
After the plot is selected, the deep cultivation of 30cm will not only loosen the soil, improve the soil conservation capacity, but also make full use of the nitrogen, phosphorus and potassium elements accumulated under the cultivated soil, and also play a part of the herbicidal action. For those who are too lyrical when they are deeply ploughed, it is necessary to carry out proper drying (drying) to prevent smashing and smashing, so that too many dead cockroaches appear, which is very unfavorable for wormwood planting.
1.3 Fertilization
In combination with the ploughshare, apply the organic farmyard manure 30-45 t/hm2 at one time, or use a layer of decomposed rare manure to spread the base fertilizer. It is used as an effective element content index for wormwood organic fertilizer: organic nitrogen, phosphorus, potassium content of more than 20%, amino acid content of more than 20%, organic matter of more than 20%, humic acid of more than 5%, sulfur content of more than 10%, no heavy metals, etc. Harmful Substance.
1.4 畦 (car)
After the soil is chopped, the whole car (car) is started, and the carton is 5 m wide, which is good for manual weeding and mechanical work. A shallow ditch is opened between every 2 厢 (car), with a groove depth of 20 cm and a width of 30 cm, which is good for flood prevention and drainage. Each 畦 (car) is high in the middle and low on both sides. The height difference is not more than 1.5 cm, which is good for irrigation. Drainage is opened around the plot, with a depth of 50 cm and a width of 60 cm. This is conducive to irrigation during drought and drainage during flooding. After the soil preparation, spray the wormwood special herbicide to kill the weeds, and plant the seedlings after about 10-15 days.
2 seedling breeding
2.1 Seed reproduction
Seeds are sown in early spring, and can be broadcast live or transplanted in 3-4 months. The live line spacing is 40-50cm, and the cover soil should be 0.5cm after sowing, or the size of the seeds should be covered. When the seedling height is 10-15 cm, the seedlings are fixed at a plant spacing of 20-30 cm.
2.2 Plant growth
The ramets propagation is the main breeding mode of artificial cultivation at present. When the seedlings grown by the rhizomes are 15-20 cm high every year from March to April, the whole wormwood is excavated after rain or after the soil is wet, according to 45 cm. × 30 cm planting, 2-3 days after planting, if there is no rain, it is necessary to drip water to protect the sputum.
3 planting
The plant spacing of wormwood was 45 cm×30 cm (75,000 plants/hm2); the planting distance was 45 cm×15 cm (150,000 plants/hm2); the reasonable planting distance was 45 cm×20 cm (10.5). 10,000 plants/hm2), the planting depth is 5~8 cm, and the planting depth of sand land or burrow land is 8~10 cm.
4 Field management
4.1 cultivating and weeding
When the average temperature reaches 9~10 °C on the day after the spring, if the Aigen bud has just sprouted and does not leave the ground, use a sprayer to cover the wormwood special herbicide for a full cover, and wait for the weeds to grow out, in March and Weeding and weeding once in April, the depth should not exceed 10 cm. After the first crop, the weeds were weeded with a small sprayer, and the second weeds were artificially weeded for a small amount of weeds after germination.
4.2 Topdressing
When the seedling height is about 30 cm, the special seedling fertilizer for wormwood is 60~90 kg/hm2 along the rainy day. On sunny days, it is dissolved by water or foliar application. Fertilizer seedlings are only suitable for the first crop that is planted in the first year. After that, chemical fertilizers should not be used, otherwise the quality of wormwood will be reduced.
4.3 Irrigation
Do a good job of clearing the ditch in rainy and rainy days to prevent stagnant water; in dry weather, foliar sprinkler irrigation is carried out for seedling heights below 80 cm; for seedling heights above 80 cm, the whole garden is flooded.
5 harvesting
The first harvest of Aiye is in June, and the harvest is to be carried out on a sunny day; the second harvest is in July, and the third harvest is before and after the frost.
Ai Cao has a role in all aspects, so the market value is naturally good, interested friends can refer to Xiaobian's explanation, try to plant wormwood, if you do not understand, you can also leave a comment below the comments, or consult the relevant information.
