The early spring sowing of carrots is easy to convulsions. Too late sowing will make the meat roots expand in a high temperature period above 25°C, resulting in a large number of malformed roots. The suitable temperature for the expansion of carrot flesh roots is 18-25°C. According to the experience in production, under the premise of selecting spring-resistant varieties that are resistant to bolting, they can be sown at a daily average temperature of 10°C and a night-average temperature of 7°C. South China can be planted in early March.
2. Soil preparation and soaking and germination.
Carrots are root vegetable crops and they should be selected for their deep soil, fertile soil, and well-drained sandy loam soil or loam soil. Deep plowing before sowing, farming depth of not less than 25 cm. Combine ploughing, 5,000 kg of farmyard manure per acre, and 15 kg of phosphorus and potash fertilizer and available nitrogen fertilizer. Carrot seeds are not easy to absorb water and breathable, coupled with the low temperature of spring sowing, resulting in slow seed germination and emergence. In order to promote early germination and emergence, soaking and germination should be carried out before sowing by soaking in warm water of 30-35°C for 3 to 4 hours, removing it and putting it in a wet towel or bag to moisturize it, and placing it at a temperature of 25-30°C. ~ 4 days, regular stirring and rinsing, until 80% to 90% of the seeds can be mixed with wet sand. After sowing, it is evenly covered with a thin layer of soil and covered with a plastic film. It can also be replaced by straw or grass.
3. Field management.
To keep the soil moist after sowing, watering or watering immediately after suppression should be carried out to create conditions conducive to seed germination and emergence. After the seedlings are released, the cover should be removed in the morning without wind. Seedlings 2 times during seedlings, the first time in 1 to 2 true leaves, remove the bad seedlings, weak seedlings and too dense seedlings; the second time in the 3 to 4 true leaves, after the seedlings will be fixed, the seedling spacing 9 cm, spacing 15 to 18 cm. Cultivated weeding is the key to carrot production. In addition, pay attention to soil during the cultivator to prevent the top of the fleshy root from forming the green shoulders.
In order to produce carrots with high yields, the whole growth period should be top dressing 2 to 3 times. The first time in the 5 to 7 days after the start of seedlings, combined with water per acre ammonium sulfate 3 kg, 3 kg of phosphorus and potassium fertilizer. The second time in 8 to 9 true leaves, the initial stage of fleshy root enlargement, that is, the period of maximum water and fertilizer, combined with watering per acre, 7.5 kg of ammonium sulfate, 3.5 kg of phosphorus and potassium fertilizer.
4. Timely harvest in phases.
Most of spring sowing carrots in Guangdong were sown at the beginning of March and generally harvested at the beginning of June. When mature, the leaves showed no longer growing, no new leaves were seen, and the lower leaves turned yellow. Harvesting too early and late will affect the properties of carrots and thus affect the yield. If there is 0 ~ 3 °C cold storage, storage after harvest, which can supply the entire summer.
Decommissioning
the ingredients of the Self-Heating Rice heating package: Inventing a
multi-purpose self-heating bag, mainly using roasting diatomaceous
earth, iron powder, aluminum powder, coke powder, activated carbon, salt
to form a bag, which can be heated to 60 °C It
can be used for heating in winter, medical hot compress, adding
quicklime, sodium carbonate and water. The temperature can be raised to
120 °C to heat meals or steamed food. The temperature is kept for 20
minutes to 100 ° C for 60 minutes and 60 ° C after 60 minutes. The
material used in the winter heating and hot compressing can be
repeatedly used, and after being used, it can be mixed with quicklime
and sodium carbonate, and then heated to heat the food.
