How to manage leeks after replanting

Generally, in the southern region, it is better to sow seedlings in early September. It cannot be sown before August 20 and after September 20, otherwise it is easy to sprout and not grow buds. If the temperature is too high, it will not form buds, and it is easy to sprout and flower.

Cabbage is generally sown in late August to mid-September, and the best time to sow is in early September.

The germination temperature of the vegetable seeds is about 20 28, and the surface of the box is moistened by splashing the rotting manure water before sowing, and the sowing is ensured to be evenly sown (can be mixed with sand), and the grass ash is covered with centimeter thickness after sparse sowing. Seedlings are seedlings 2 3 times during the whole seedling period, apply light human and animal manure 2 3 times, when the seedlings appear 4 true leaves, the seedling age is about 25 days, with * moved out of the seedbed to 10 * 15 cm plant row spacing for false planting, watering thin human and animal manure urine roots, false planting 15 20 days or so to form old strong seedlings can be planted, before false planting will be a small number of individual extra-large seedlings, mutant seedlings pulled out and thrown away.

Leek planting needs sunlight, medium light intensity, strong negative tolerance, but too weak light, less accumulation of photosynthetic products, less and weak tillers, low yield, and easy premature aging; The light is too strong, the temperature is too high, there are many fibers, and the quality is poor.

Leeks belong to the lily family perennial root vegetables, strong adaptability, cultivated everywhere in China, many areas in the south can be produced all year round, although the aboveground part of the northern winter is dead, the underground part enters dormancy, and germinates and grows after the topsoil thaws in spring.

Leeks like cold and cool, cold and heat tolerant, the suitable temperature for seed germination is more than 12, the growth temperature is 15 to 25, the underground can tolerate lower temperatures, strong adaptability to soil texture, suitable pH, large fertilizer demand, strong fertilizer tolerance.

In winter, leeks are cultivated and do not see the sun.

Water spinach planting time and month.

When to plant bracken in spring, bracken is generally planted in February and March, and the temperature should be kept at 25 degrees. Therefore, it is necessary to use relatively fertile soil when planting. When to plant spinach in the summer?

In the summer, spinach can be grown in April-May. Good ventilation is required during the maintenance period to avoid pests and diseases caused by a stuffy environment. When to plant spinach in the fall?

Autumn temperatures are relatively low, so it should be planted around September. It is not very cold-tolerant, pay attention to heat preservation measures, otherwise it will prevent the growth and development of its guess bridge. When to plant spinach in winterIn winter, you can plant spinach in the greenhouse from November to December, and the temperature should be kept above 10 degrees, otherwise it will be frostbitten.

Water spinach planting methods and steps.

The sowing date of bracken is determined according to the local climatic conditions and the characteristics of the variety. If the average daily temperature stabilizes above 15 degrees, seeds can be sown. 1.

Before planting, water spinach seeds need to be soaked in warm water at 30-40 degrees for 30 minutes, and then soaked in water for 24 hours. 2.Take out the soaked bracken seeds, wash them, put them at about 25 degrees to start germinating, and wait for the seeds to turn white before sowing.

3.Walk through a shallow trench 2 3 cm deep and 15 cm apart. Then sprinkle the seeds of the bracken evenly in the ditch, then cover with fine soil, and finally cover with plastic film.

After a week, the seedlings can appear.

Water spinach planting time.

Water spinach is a common vegetable in the southern provinces of China. It is found only on the southern slopes of the Qinling Mountains in Hanzhong, Shaanxi Province and Bikou, Wenxian County, Gansu Province, and is also cultivated in India, Sri Lanka and Japan.

Water spinach growth cycle.

The growing period of water spinach is between 35 and 45 days. Generally, seedlings can be harvested and eaten when they grow to 20 to 30 cm. Generally, after harvesting three or four times, the bracken should be re-processed, leaving only one or two buried forest nodes, because the side branches are easy to grow weak, and the growth will also deteriorate.

Water spinach cultivation costs and profits.

Water spinach has certain economic benefits and good market prospects. In general, it is cultivated out of season, 4 months earlier than conventional cultivation, and can be harvested by the end of November. This allows for higher yields.

Generally, the yield per mu is 3000-3500 catties, and the output value per mu is about 6000 yuan.

Tips for water spinach planting techniques.

Water spinach is heat tolerant, so it generally prefers a humid and warm climate. It needs more fertilizer and water, so it must be given plenty of base fertilizer. However, it should be noted that during the hot and rainy season, weeding and pest control are very important in Abel Tamata.
