Autumn vegetable growing technology
1. Variety Selection Long-stemmed cabbage is planted. The plant stands upright and the plant height is 45-50 cm. The leaves are long and oval, and the leaf color is light green, with smooth leaf surface, white petiole and flat stem. When young, it can be eaten as a cabbage, and it can also be processed and listed as pickle. After fully matured, it is exclusively for marinating. Adaptability, high yield, plant weight up to 0.75-1.0 kg, per mu up to 3,000 pounds. 2. The preparation of Chinese cabbage seeds is small and requires a flat topography and fine crushing of soil particles in order to ensure high seedling rate and uniformity of emergence. In order to enhance the soil's ability to retain water and fertility, the soil will be soft, the roots will develop well, and the range of water and nutrients will be increased to require deep plowing. More local rainwater should be used for sorghum to ensure smooth drainage. 3, Shiji Chinese cabbage has a long growth period, a large amount of growth, and requires more nutrition. Due to the organic fertilizer (the seedlings have the effect of promoting the development of the root system and improving the resistance of Chinese cabbage, it is necessary to reappropriate the base fertilizer mainly composed of organic fertilizer. Generally, 3000-4000 kg of manure with better quality per mu can be used, or compost 5000-6000 Kg, 100 kg of plant ash, 15-25 kg of superphosphate, and 10-15 kg of potassium chloride if conditions permit.
4.1, sowing time and the amount of seeding time is generally sowing in early September, the seedling period of 20 days, the amount of seed used per acre of 100 to 150 grams. 4.2. Seed Treatment Before sowing, Chinese cabbage is sown with seeds. The seeds, seeds, and seeds will be eliminated. The seeds with full seeds, uniform and viable seeds will be sown. Seed disinfection with seed dressing, with 1% concentration of 50% thiram, 90% of phosphorus aluminum 1:1 mixed powder dressing for 15 minutes. 4.3. Seeding method The method of sowing seedlings is used. Firstly, in accordance with the prescribed spacing of 25 centimeters and 35 centimeters, the pods should be used as shallow holes of 1 to 1.5 centimeters, and seeding seeds of 8 to 10 seeds per hole. 4.4 After sowing management After sowing, use fine soil leveling points, and then slightly suppress, so that the seeds and soil are closely connected. If the soil is dry at the time of sowing, it can be watered in the hole first, and then soaked in the soil after soaking in the soil. The amount of seeds used per acre is 100-150 grams. 5, field management
Intertillage and weeding work in conjunction with seedlings. Usually after watering in the thinning, the manure is set and the roots are planted in a timely manner after watering or raining to prevent ground panel knots, promote soil aeration, and remove weeds. At this time, the cultivator should be shallow. Generally, the degree of topsoil is broken and the depth is about 3 cm. The cultivator weeding after the seedlings has a depth of about 5 cm. It is necessary to grasp the principle that the distance should be deep and the seedlings should be shallow. With deep ditch sorghum growers, they should loosen the bottom of the ditch and the sides of the sorghum and loosen the squats on the sloping side or sampan surface so as to facilitate the smooth passage of the ditch to facilitate drainage and irrigation. 6, pest control 6.1, disease control disease 1 downy mildew. It was sprayed with 64% antivirus WP 500 times. 2 soft rot and black rot. Spray 3000-4000 times of streptomycin sulfate or 70% of agricultural streptomycin sulfate. 3 black spot. Spray 500% 75% chlorothalonil or 70% dexamethasone zinc 500 times. 4 virus disease. To control aphids mainly to control the occurrence of diseases, the choice of 10% imidacloprid 1500 times, or 50% wards 1500-2000 times spray fog, after the onset of disease can be used 1.5% plant disease Ling 1000 times spray. 6.2, pest control 1 cabbage caterpillar, diamondback moth can be used 1000 times BT preparations or 25% diflubenzuron 500-1000 times spray. 2 soil, earthworms, can be sprayed 4% enemy horse powder or 4% enemy powder 1.5-2 kg per mu. 7. Harvesting can be harvested gradually from mid-November.
