1. 1 plot selection

Choose sandy loam with deep plough layer, soft soil, good water permeability and good fertility.

1.2 Fine soil preparation

After selecting the plot, thoroughly remove the roots and weeds of the previous crops, dig deep and sun thoroughly, so that the soil is fine and flat, and plow and rake.

2. Apply base fertilizer, grasp the season and sow in real time.

2. 1 Apply base fertilizer. Before sowing, apply decomposed farmyard manure 1000- 1500 kg/mu, spread it evenly in the ground, and turn over till the fertilizer and soil are fully mixed.

2.2 Select improved varieties. Select varieties with disease resistance, lodging resistance, high yield and high quality. Such as: short leaves 13, large and long folds, etc.

2.3 Grasp festivals and sow in real time.

Planting festivals and methods, according to different altitudes, adopt different planting methods: generally, in areas above 2000 meters above sea level, you can adopt mixed planting methods (mixed planting of potato and radish seeds), or reserve rows for interplanting, and the best festival is around mid-September; In areas below 2000 meters above sea level, the whole plant can be used, and the best season is1early October.

Planting method: mixed planting: potatoes can be planted in the field according to the planting method in Da Chun, and then planted in the field with 2 kg/mu of seeds, or planted as needed, and then leveled; Reserve planting rows, and plant radish seeds in one meter and Da Chun corn in one meter according to a 2-meter composite belt. Radish seeds can be sown as needed or drilled, and the row spacing between plants is about three inches; After sufficient planting and soil preparation, directly spread the seeds evenly in the field, rake them flat, or plant them in the field by transplanting.

3. Strengthen on-site management.

3. 1 weeding intercropping

Weeds in the field can be cleared in time according to the growth and fertility at the seedling stage, and seedlings should be planted at intervals to achieve reasonable close planting, with about 70,000 plants (ponds) per mu.

3.2 Water and fertilizer management

Urea 5- 10 kg can be applied at seedling stage to cultivate strong seedlings; Bolting and flowering are the key stages of water and fertilizer. If it is dry land, water can be supplied properly. During this period, urea 10- 15kg/ mu can be applied topdressing to make plants grow healthily and lay a good foundation for flowering and pod setting.

3.3 Pest control

Radish seeds are prone to pests at seedling stage, mainly fleas and diamondback moths, and aphids at flowering stage, so biological and chemical control can be carried out in time.

Biological control: generally use natural enemies for control, such as ladybugs.

Chemical control: The control effect is the best at the initial stage of injury, and it is generally appropriate to control at seedling stage and full flowering stage. It can be used to clean once, kill enemies, dichlorvos, Jin Dadi, pyrethroids and other public hazard chemicals, and it is better to prevent them twice.

4, timely harvesting

More than 80% of the total area can be harvested when it is ripe. Choose to cut, dry and thresh in sunny days. Plant stalks are used as animal husbandry feed or orange stalks are returned to the field for treatment.
