October Red 1 No.2 and No.2 are used for mid-late purple flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering, China flowering. Because the climate is suitable, dry seeds can be sown without any facilities. In the seedling stage, the seedlings should be pulled out in time, the seedbed should be kept moist, and the diluted decomposed manure 1 ~ 2 times should be applied to remove pests frequently.

2. Mustard: potherb mustard was planted in batches from mid-August to1early October. 10 Mustard is bred from late August to early October. Mustard for fresh stems is cultivated in Dashitou, Chengdu and Ji 'an, Jiangxi from mid-August to early September, and harvested from 1L to 65438+February. Mustard (mustard tuber) is used to process stems. The improved varieties are grass kidney and three-story building in Sichuan, and the semi-broken leaves in Zhejiang are short heads. There are two varieties of mustard, Jixin mustard in Guangdong and Bao Bao Qing in Sichuan, which were bred in September and harvested in February-March of the following year. Mustard seeds per mu100g, others 50-70g. The seedling age is 30 ~ 35 days.

Field planting

1. The row spacing of lettuce, lettuce, Chinese cabbage and celery is (17 ~ 23) cm× (10 ~17) cm. Fully water after planting, water L ~ 2 times a day on the second and third days, and reduce watering after survival (the same below) autumn lettuce by 33 cm × 27 cm; Early-maturing purple flowers bloom in China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China, China and China. China blooms, China blooms, China blooms, China blooms, China blooms (40-50) cm× 30 cm, and China blooms, China blooms, China blooms, China blooms, China blooms, China blooms, China blooms, and China blooms (50-60). Purple moss can also be planted in the fields and boundaries of other vegetables.

2. The row spacing of mustard, mustard and fresh stem mustard is (53 ~ 67) cm× (40 ~ 50) cm, and mustard tuber is planted in four rows (30 ~ 33) cm× (15 ~ 20) cm; Potherb mustard (27 ~ 33) cm× (17 ~ 27) cm.

3. Cabbage and cauliflower (broccoli) in autumn and winter crops are mostly mid-late maturing varieties, so they should be planted thinly, and the row spacing is (53 ~ 73) cm× (40 ~ 53) cm.

The leek planted in April will be planted in September at the beginning of 10. The base fertilizer is suitable for applying decomposed organic fertilizer, with long fertilizer efficiency and soil improvement. Before planting, cut off the long fibrous roots, leaving only 2 ~ 3 cm leaves, and cut off a section of the top to reduce the evaporation of leaves. The row spacing is (27 ~ 40) cm× 26 cm, and each cluster 15 ~ 20 plants. It is not advisable to plant too deep or too shallow, just bury the leaf sheath. In order to facilitate intercropping, every two rows of leeks are a group with a spacing of 66 cm.

5. Oenanthe javanica is planted from late August to September and harvested from mid-February to mid-April. In the first ten days of August, seed stems with a stem diameter of 1cm (600 kg per mu) were selected to accelerate germination (piled in the shade, covered with grass, watered and moisturized), and after germination, the seed stems were cut into small pieces with a length of 30 cm, and planted around the border, with the base of the seed stems facing the border and the tip inward, with a distance of 5-6 cm. In the middle of the border, spread the seeds evenly with bamboo poles, without crossing, with a spacing of 3 ~ 6 cm. The stem can neither enter the mud nor float on the water, so it should be stuck in the mud.

operate

1. After autumn, when the outdoor maximum temperature is stable below 28℃, remove the sunshade net on the shed to enhance the lighting in the shed. When melons start to pull vines, when tomatoes fall, they should be inserted into word stands or hung with plastic ropes. Prune tomatoes, mostly cucumbers, keep 2 ~ 3 vines for watermelons, and pick other branches (vines) in time; Picking the side branches of eggplant and pepper below the first branch; Pick old yellow leaves from eggplant. Water management should keep the soil moist and avoid excessive water and sudden dryness and wetness. Avoid watering, but ditch irrigation (water can't drown the surface of the border). Avoid too much nitrogen fertilizer, and apply fertilizer to raise seedlings as appropriate before fruiting.

2. Root vegetables, radishes and carrots should be interplanted and hoed (pulled) in time. Don't water too much and too often, or you will grow lateral roots or fleshy roots with black hearts; It should be wet and dry, watered thoroughly and aired for a while. Top dressing should not be too much, especially too much nitrogen fertilizer, otherwise the leaves will grow white; Potassium moon bar should be supplemented during the expansion period of fleshy roots. Generally, topdressing is 1 ~ 2 times after "broken belly".

5. Other autumn vegetables and green leafy vegetables should be watered frequently, L ~ 2 days 1 time, and some fertilizers should be applied after 5 ~ 7 days. Garlic (seedling) is basically the same as green leafy vegetables, but the interval between watering and topdressing is slightly longer. Cabbage and mustard should be watered with plenty of water every time, with an interval of 4-5 days. Water should be controlled during the heading stage of Chinese cabbage, with emphasis on topdressing at the budding stage and the initial stage of product formation. Autumn potatoes should keep the soil moist.

Pest control This month is the outbreak period of various pests. For pest species and control methods, please refer to garden cultivation in July and August. If Spodoptera exigua harms Plutella xylostella and Pieris rapae at the same time, pesticides such as Diji and Cai Xi can be used for control.
