Mustard planting: how to grow heart mustard in autumn?

How do you plant mustard seeds in autumn? What should I pay attention to? Please also ask netizens to point out that planting heart mustard in autumn can refer to the following methods for planting: 1. Cultivation season of mustard seed: The seeds can be sown from July 20 to July 25 by seedling transplanting and from July 25 to the end of July by direct seeding. It is usually planted in late August and harvested from late October to early November. 2. Selection of mustard planting fields: Select neutral, convenient irrigation and drainage, good water quality farmland planting. Fine soil preparation, deep and high ridge, ridge width (continuous ditch)1.2~1.3 meters. 1500~2000 kg decomposed organic fertilizer and 30~40 kg NPK compound fertilizer are applied per mu as base fertilizer when soil preparation and cultivation. 3, seed and seedling of the heart mustard: There are two ways to seed the heart mustard: one is seedling transplanting, the amount of seed used per mu is 25~40 grams, and the seedbed is 30 square meters; the other is direct seeding, sowing 2~5 seeds per hole, covering the hole after sowing to prevent rain washing or sun exposure. It is best to cover with sunshade net, strive to sow whole seedlings, and timely do a good job in field management such as thinning seedlings, watering and weeding. 4. Transplantation of heart mustard: Double row planting, row spacing 65 cm, plant spacing 25 cm, about 4000 plants per mu. Seedlings cultivated by seedling transplanting method should be transplanted with soil, and stiff seedlings, weak seedlings and sick seedlings should be eliminated. After planting, 0.5% urea aqueous solution was applied in time to improve survival rate and accelerate early onset of rejuvenation. 5. Daily management of heart mustard: Timely supplement seedlings: after planting, in case of high temperature and dry weather, it is easy to appear sick seedlings, stiff seedlings and dead seedlings, so it should be supplemented in time to strive for comprehensive balance and early development. Fertilization and watering: due to the rapid growth of cabbage mustard, it needs constant fertilizer and water supply. Fertilize once every 10 days or so before ball formation (from planting to ball formation), drench 750~1000 kg of human excrement per mu, or drench with 8 ~ 10 kg of ammonium bicarbonate and 8~10 kg of calcium superphosphate mixed with water for 3~4 times. When the heart rate of wrapped mustard reaches about 5%, it can be re-applied with 20~30 kg urea and 15 kg potassium chloride dissolved in water per mu. For fields with fast growth and low fertility, ammonium bicarbonate and calcium superphosphate can be added to water every 7~10 days. 6, mustard pest control: 50% phoxim 1000 times solution was used to control underground pests when sowing. After emergence to harvest, the main control methods are: 20% fenvalerate 2000 times solution plus 3% 5% Xinqike 1000~1200 times solution, or 5% chlorpromazine 1500 times solution, or 0.6% insecticide 1500~2000 times solution. At the initial stage of seed wrapping, 200 mg/kg streptomycin was sprayed to control soft rot, once every 7~10 days, and continuously sprayed 2~3 times.
