After the cabbage rains, the seedlings don t grow long, what kind of mediation?

If the cabbage seedlings are stiff and do not grow after the rain, it may be because the soil is too wet, resulting in a lack of oxygen and nutrients in the roots. To improve the situation, the following measures can be taken:

1.Drainage: If the soil is too wet, it needs to be drained as soon as possible. Drains can be dug to let excess water flow out.

2.Fertilization: Lack of nutrients may lead to stiff seedlings, which can be fertilized in moderation to provide nutrients. Nitrogen and phosphate fertilizers are recommended.

3.Loosening the soil: Loosening the soil improves soil permeability, which is conducive to root growth.

4.Pest control: If pests and diseases occur, control measures should be taken in time.

If the above measures do not solve the problem, it is advisable to consult an agricultural expert or professional.

Overview:Spray nutrients plus growth-promoting plant hormones.

Elaboration:When the stiff seedlings do not appear, spray brassin3% potassium phosphate monobasic plus urea solution.

Cabbage seedlings are beaten by rain, and they may not be able to recover.

Cabbage propagation and cultivation techniques.

Methods of reproduction. Fertilization and land preparation: 2000 to 3000 kg of organic fertilizer per mu, 60 kg of potassium sulfate compound fertilizer as base fertilizer.

Deep ploughing 30 to 40 cm, leveling and raking fine after ridge spacing, ridge spacing 60 cm, ridge standard for the bottom width of 35 to 40 cm, neck width of 20 to 25 cm, ridge height of 20 cm. The soil ridges are compacted to facilitate sowing.

Watering to create moisture: When the soil moisture is insufficient, it is necessary to water and create moisture before preparing the land after applying basal fertilizer.

Fine sowing: The main sowing method of Chinese cabbage in autumn is live broadcasting, which is divided into two methods: strip sowing and hole sowing.

Strip sowing: open a shallow ditch to a centimeter depth in the middle of the ridge, sprinkle the seeds evenly in the ditch and then cover the soil with liquid pressure to prepare for finesse, with a seed amount of about 120 grams per mu. You can also use cabbage seeding machine, sowing in the middle of the top of the ridge, with a seed amount of 80 to 100 grams per mu, and the seeding machine should be equipped with soil covering facilities.

Hole sowing: at the top of the ridge according to about 55 cm hole spacing, and the soil ridge perpendicular to the length of 10 to 15 cm, deep to centimeter of the ditch, each ditch sowing 5 to 6 seeds, after sowing cover fine soil centimeter compaction, per mu with 100 to 120 grams of seeds.

Cultivation techniques. Seedlings: 5 to 6 days after the emergence of seedlings, the first seedlings, to the weak and strong, strip sowing seedlings spacing 2 to 3 cm; When the Chinese cabbage has 3 to 4 leaves, the seedlings of the strip sowing plot are 8 cm, and about 3 plants are left in each hole when the hole is sown; After another 5 to 6 days, the third seedling is sent.

Seedling: Seedlings grow for about 25 days to reach the cluster stage, according to the plant spacing of 50 to 60 cm seedlings, leaving about 2,000 seedlings per mu. If the lack of seedlings is found, it should be replanted in time, and the seedlings should be watered in the afternoon or cloudy day on a sunny day.

Cultivating and weeding: 3 times of tillage, respectively after the second seedling, after seedling setting and in the middle of the rosette. Cultivating combined with weeding.

Reasonable watering: If the bottom moisture is insufficient, water in time after sowing to ensure that the seedlings are strong and strong. After thinning seedlings and setting seedlings, water 1 water each. Initial watering promotes the growth of trees. During the balling period, watering should be carried out in combination with top dressing, and the amount of watering should be large and uniform. In the later stage, appropriate water control promotes the core wrapping.

Timely top dressing: 15 to 20 acres of nitrogen, phosphorus and potassium compound fertilizer per mu at the rosette stage. At the beginning of balling, 30 to 40 kg of nitrogen, phosphorus and potassium compound fertilizer were applied per mu.

No more topdressing within 20 days before harvest. Combined with spraying, spray foliar dust fertilizer every 7 to 10 days at the rosette stage, a total of 2 to 3 times, using a mixture of urea and potassium dihydrogen phosphate, sprayed after 16 o'clock.

Harvest: After mid-November, Chinese cabbage basically stops growing and enters the harvest period. After the beginning of December, it should be harvested in time to prevent frost damage.
