At present, alpine cabbage has been cultivated in many places in China. The most suitable elevation for the cultivation of Chinese cabbage in the alpine region of Hubei is above 1200m, and it will be listed from June to October. Different climates at different altitudes, the suitable sowing date, planting period and marketing period of Chinese cabbage are also different. Gradient should not be used for seeding, staggered at the peak of the market to facilitate balanced market supply and stable vegetable prices. I. Problems and countermeasures of Chinese cabbage in alpine production 1. Unreasonable farming methods make soil degradation and pest control difficult, and affect the full potential of synergy, which requires scientific combination of breeding and breeding. Due to the relatively simple variety of vegetables and sputum, serious cropping, coupled with unreasonable ratio of chemical fertilizers and pesticides, low application rate of organic fertilizers, lack of medium and trace elements, and unreasonable fertilization methods, the soil fertility is degraded and the efficiency of fertilizer utilization is reduced. Obstacles (root swollen disease, soil acidification, new disease appearing constantly) are gradually increasing, and the difficulty of prevention and control is increasing, which affects the full potential of synergy. Promote scientific breeding under the premise of stable production and increase production, select disease-resistant and stress-resistant varieties and high-efficiency mouthwash mode, use precise formula fertilization and organic fertilizer to replace part of fertilizer technology, use pest control green control, pesticide precision and efficient application technology and functional microbial soil micro-ecology Remediation technology, soil acidification improvement technology, overcoming the obstacles of continuous cropping of vegetables, achieving sustainable development of coordinated vegetable yield, quality and safety, and agro-ecological environmental protection, while reducing agricultural production costs and promoting farmers' cost-effectiveness. 2, the occurrence of clubroot disease limits the production of alpine Chinese cabbage, and advocates the application of comprehensive biological control technology The pathogen of clubroot disease is Rhizoctonia solani, a genus of the genus Tumorus of the protozoa. The dormant sporangium remains in the soil over the winter with the diseased residue, and can survive for more than 6 years in the soil. It has strong infectivity and many transmission routes. It can pass the diseased seeds, seedlings, soil, diseased plant debris, running water, Insects, farm tools, personnel activities, etc. The cruciferous vegetables are highly specialized, and can be harmful to the cruciferous seedlings or adult plants. The field with heavy disease causes no harvest; and there are many physiological races, which are easy to produce resistance. Promote the application of integrated biological control technology. Pay attention to isolation, change with non-cruciferous crops; adjust soil pH; add organic fertilizer, use biological preparation "NBF-926", calcium cyanamide to disinfect soil; use anti-root disease varieties. 3. The unprocessed Chinese cabbage has no effect on the environment, and promotes the utilization of tail vegetables. Only the alpine vegetable industry in Changyang County produces more than 200,000 tons of tail (discarded) vegetables every year. The throwing of the tail vegetables will seriously pollute the environment and cause pests and diseases. It is recommended to use the functional microbial fermentation process to process the tail vegetables into organic fertilizer and return to the field to achieve the purpose of resource utilization and soil fertility. Second, the potential variety recommended Every year, for the demand of alpine varieties, the special varieties of alpine vegetables are screened in the alpine vegetable producing area and promoted in the production area. Alpine Chinese cabbage planting varieties require medium maturity, the plant is resistant to low temperature and resistance to convulsions, disease resistance, especially resistance to madness (viral disease), white spot disease, black spot disease, edge blight, and anti-root disease in areas of clubroot disease; Good commodity, shell shape, single ball mass 1.5kg, leaf color dark green, petiole flat, yellow ball inside, short heart column, tight ball; high yield, 667m2 output 4000kg or more; resistant to storage and transportation Not easy to defoliate. Japanese and Korean varieties have advantages in cold tolerance and anti-root disease, and they occupy a dominant position in the alpine cabbage seed market. However, in recent years, domestic research on anti-root disease varieties has been strengthened and many excellent varieties have been selected. The following two varieties have been tested and demonstrated in Yichang and Enshi for many years, and they have performed well in production. 1 Lucky Ruyi Chinese Cabbage Hubei Vegetable Valley Co., Ltd. distributes varieties and is resistant to root disease. It is resistant to low temperature in early spring and high temperature in early summer. It is suitable for planting in early spring greenhouses and high cold ground. Plant type erect, compact, leaf color green, leaf number, good quality, good commodity, shell-shaped, yellow heart, single ball mass 1 ~ 2kg, ball height 25 ~ 30cm, ball transverse diameter 15 ~ 20cm, ball tight In fact, it is not easy to defoliate when transporting, and can be sown above 13 °C. It is currently the leading species in the Changyang area. 2 anti-518 Chinese cabbage Distribution of Changxing Vegetable Seeds Business Department of Jiayu County, Hubei Province. Early-maturing varieties can be harvested 60 days after planting. Strong disease resistance, special resistance to clubroot disease. Strong resistance to stress, strong growth potential, straight cylindrical, deep yellow heart, single ball quality 2 ~ 3kg, late convulsions. The high vegetable rate is suitable for late spring, summer cold and autumn planting. The above are the problems and countermeasures in the alpine production of Chinese cabbage prepared by Hui Nong. I am a kind of vegetable that has higher nutritional value and taste than ordinary cabbage. Farmers who have the idea of ​​planting alpine cabbage Friends can refer to it!
