How to plant green seeds in Shanghai?

Field land planting:

1. Variety selection

Summer varieties choose varieties with high temperature resistance, disease resistance and high yield, such as Xia Di and Xia Fei, with a growth period of 30 days. Autumn, winter and spring varieties select varieties with low temperature tolerance, disease resistance and high yield, such as Jinpin, Huaguan, Huajin, growth period 50d~60d.

2. Land preparation and trenching

The deep ploughing is divided into a long border (35m) with a width of 1.6m, a height of 0.2m and a width of 0.3m. The length and width are neat and beneficial to management. The soil of the border should be fine, uniform and flat, which is beneficial to seed germination and high seedling emergence rate. At the same time, dig a good drainage ditch around, the ditch width is 0.3m, the ditch depth is 0.3m, the ditch is connected with the ditch, which is beneficial to drainage.

3, sprinkler irrigation, inter-seedling

Sprinkler irrigation should be carried out twice a day in the morning and evening before emergence, and once a day in the morning or evening, from 2 leaves to 1 heart stage to 3 leaves and 1 heart. L0~15cm should be carried out between seedlings, which is beneficial to plant growth and increase yield.

5. Scientific fertilization

Re-apply base fertilizer and topdressing for many times. Base fertilizer per 667m applied 48% ternary compound fertilizer (15) 25kg, 12% calcium superphosphate 50kg. Topdressing was carried out at 4 leaf 1 heart stage, 6 leaf 1 heart stage and 8 leaf 1 heart stage, respectively. 48% ternary compound fertilizer 20: 46% urea 10kg was applied each time, and then pumped and sprinkled irrigation to prevent fertilizer from falling on the leaves and causing seedling burning.

6. Harvest

Ten leaves and one heart can be harvested and sold, if sold in other provinces, stop spraying water one day before harvest, which is beneficial to long-distance transportation. When harvesting, use a special harvesting knife to cut from the 1 / 2 leaves of the base, put the vegetables neatly into the basket and sell them.

Balcony planting:

1. Choose fresh seeds that have not passed the shelf life.

2. Prepare the flowerpot. If the pot is not enough, you can also plant it under the chili, under the rose, without taking up space. Rotten leaf soil is the best, fertile and soft. Make the soil as loose as possible.

3. If the temperature is higher, it will sprout in four or five days. At this time, less water, often bask in the sun, no fertilizer. Otherwise, it is easy to grow and the leaves will turn yellow.

4. Under the condition that the leaves are bigger and stronger, fertilizer can be applied. Mash chicken manure or other organic manure to soak in water and apply thin fertilizer frequently.

5. As the sowing is relatively dense, it can be eaten by the seedlings, which leaves more space, and the rest of the seedlings grow better.

6. Shanghai green is suitable for transplanting. If you have more flowerpots or extra space at home, you can plant the seedlings from time to time and pour some water on them. It is easy to survive, and if you apply enough fertilizer, you can grow a big one.

7. As long as more fertilization, watering and basking in the sun, ventilation and ventilation, Shanghai green is very good, and other vegetables can be mixed together to sow seeds. Save more space.
