Cultivation Techniques of Chinese Medicinal Plant Hawthorn and Prevention and Control Technique of Anthrax

Hawthorn is an alias for Zaopi and Yam meat. It is a plant of the family Hawthorne. It uses the flesh of the seeds to remove the medicine and has the functions of tonifying the liver and kidney and astringent antiperspirant. It is one of the main cash crops in Huoshan County.
I. Cultivation techniques
1, characteristics and growth habits. Hawthorn is a deciduous tree or shrub, 2-10 meters high, single leaves alternate, leaves oval, acuminate, base cuneate, umbellate axillary, leaf anterior flowering, yellow flowers. Drupe oblong, red at maturity, flowering 2-3 months, fruiting period from April to October. Hawthorn is generally distributed in the low-humid hills of 250-800 meters above sea level in gentle slopes with thicker humus in limestone soil. There are few wild hawthorns in barren lands. Hi warm and humid climate. Frost damage during flowering will severely reduce production.
2, selection and preparation. Choose sandy loam with good drainage and deep soil. After the house front, the idle land beside the Tianbian Canal can also be planted. The organic fertilizer is applied at a rate of 4,000 to 5,000 kilograms per 667 square meters.
3, breeding methods (1) seed nursery. Choose fruits that are large in shape, full in size, free of pests and diseases, peel the flesh, soak in human urine for 15-20 days, dig a deep hole in the sunny place in November, apply organic fertilizer at the bottom of the hole, spread the seeds, and then use Pig cow manure or miscellaneous fertilizer covers 15-20 centimeters. It will be dug and opened at the beginning of April of the next year. All kinds of sub-embryos have sprouted and they can be taken out and sown. The nursery should choose moist, fertile, loose soil, deep plowing, in addition to the net weeds, Shizu base fertilizer, flat pods, lotus root width 1.4-1.7 meters, in the pod on the depth of 20 cm, spacing 35 cm, width 25 The centimeters of the ditch, the ditch and then the base fertilizer, apply 1500-2000 kilograms per 667 square meters, broadcast the seed on the base fertilizer, the seed distance 3-5 centimeters, after the broadcast cover with the fire and earth dust and cover the fine soil level. After sowing, it prevents humans and animals from stepping on it. If seeds that have not been treated with basal germination are broadcast directly on the seedlings, they will not emerge in the first year. They will not be able to emerge until April of the second year, and the seedlings will not be neat. After emergence, we should timely cultivating and weeding, and fertilize properly. When the seedlings are about 1 meter tall, they can be transplanted.
(2) cutting seedlings. Choose strong, disease-free and fruitful mother plants, cut branches of about 66 centimeters in length in February and February, and soak in soil with 1:20000 sodium nattoacetate solution. Insert soil by spacing 33 centimeters and spacing 10-13 centimeters. In about 13 centimeters, the branches shall be ploughed into the ground and the base bed fertilizer shall be applied to the seedbed to keep it moist. Conditional use of a small shed can cover the moisturizing and heat preservation. After the branches have grown to survive, they can be transplanted.
(3) Colonization. Seed nursery and cutting seedling transplanting planting time is winter and spring, with high survival rate in winter. Choose sunny, fertile, deep soil land planting. The depth of the opening hole is determined by the length of the main root of the seedling. When planting, the roots of the seedlings are required to be comfortable, do not bend, and do not harm the roots. Each plant is 2.7-3 meters apart. Generally, 60 plants per 667 square meters of mountainous area are planted, covered with soil, and poured with appropriate amounts of water and water.
4, field management. The management of field crops in Hawthorn must be done in the same way as the four-divisional ones, that is, diligent weeds, hard-soiled earth, diligent pruning, diligent fertilization, and prevention of pests and diseases. Specific can be divided into.
(1) Seedling management. Before the emergence of the seedlings, we should always keep the soil moist and prevent the ground from being hardened and covered with grass. Watering when dry. After the seedlings have been unearthed, cover grass is removed and weeding is often done. The seedling height is about 15 centimeters and topdressing dilute manure once to accelerate seedling growth. If the seedlings are too dense, when the height of seedlings is 12 cm, the seedlings will be planted. When the seedlings did not reach the height of colonization, they were covered with weeds and pig cow dung before winter, in order to facilitate heat preservation and moisturizing, so that the seedlings could safely pass winter.
(2) Management after planting. After planting, cultivating and weeding should be done 4-5 times a year to keep the weeds around the plants. When transplanting, if the base fertilizer is sufficient, it may not be top-dressed in the same year, and then top dressing once in the spring and autumn. The amount of fertilization depends on the age of the tree. Small trees will be used less, and large trees will be applied more. For trees older than 10 years, 10-15 kilograms of livestock manure can be applied to each tree. The method is to open the ditch around the tree, apply the fertilizer after it is watered, etc., so that the ditch is covered with water. Watering should be noted during the first year after the planting and the fruiting period. If the flowering period or the drought in summer occurs, it will result in falling flowers and fruit. The top branches were cut off before the second year of February in the second year of planting to promote the growth of lateral branches. The saplings at the base of the tree were cut off each year in early spring to promote trunk growth. Pay attention to the renovation of the tree canopy and the sparse shearing of the lower branches, so that the canopy branches are evenly distributed to facilitate ventilation and light transmission and improve the rate of results. Saplings should be earthed 1-2 times a year. Adult trees can be earthed once every 2-3 years. If roots are found on the surface, roots should be used in time.
Second, hawthorn anthrax prevention and treatment. Hawthorn anthracnose, also known as black fruit disease, the disease rate of up to 50%, and the decline in tree vigor, the results of the second year decreased, affecting the yield and quality.
1, the symptoms. The incidence of young fruit, bacteria and more invasion from the top of the fruit, lesions spread downward, the disease is black, red-brown edges, lesions gradually extended to the whole fruit, and black shrinkage, and more do not fall off. The onset of the disease was initially a brown-red dot, which expanded into a round or oval black depression spot. The lesion was red-brown with a red halo surrounding the lesion. Under humid conditions, the diseased part produced small black spots and orange-red spore masses. Lesions combined to make the whole fruit black and dry off.
2, the incidence of law. The pathogenic bacteria used hyphae and conidia discs to overwinter on diseased fruits, and conidia infested in the middle and late April. During the growth period, conidia are produced and spread by wind and rain to expand damage. The incidence of fruit anthracnose is from July to September. In those years where the number of overwintering bacteria is large, rainfall is heavy, and humidity is high, the onset is early and heavy; the old age, the growth and decline are heavy, and the onset is vigorous; the onset is extensive, and the incidence of pruning and fertilization is light.
3, control methods (1) agricultural control. After the harvest of the autumn fruit, the diseased branches were cut off, and the diseases on the ground were buried to reduce the source of overwintering bacteria; the field management was strengthened, and pruning, watering, and fertilizing were used to promote robust growth and enhance disease resistance.
(2) Chemical control. In the early stage of disease, spray 25% SPK Emulsion 1,000 times or 50% SPW 1000-2000 times to prevent and cure.
