The growth of cabbage preferred temperature in 25-30 ℃, the best planting time in the spring and fall. Pick a rich, airy sandy loam to plant, configure the soil before planting, apply some organic fertilizer. Select suitable seeds, soak in warm boiled water before sowing, encapsulate in damp gauze, and subsequently put into the environment of 30 ℃ to germinate. Sow the seeds down, and after sowing, apply fertilizer, spray water to maintain moisture, and keep them under abundant sunlight.

PlantingTime

Cabbage is a very good vegetable to grow, is not harsh on the growing environment, and can be planted in all parts of the country. For the hollow cabbage, the growth of the preferred temperature in 25-30 ℃ or so, the best planting time in the spring and fall 2 seasons, these two seasons of the climate is suitable for planting can be as early as possible after the sprouting period of growth, the survival rate is also very high.

Preparing the soil

It can't hold water at the root, so it can't be planted in a low-lying area where water is stored, so you can pick a rich, breathable sandy loam to plant. If it is a small amount of potted plants, you can configure the soil yourself. After the soil is clear, you also need to apply a certain amount of organic fertilizer as a base fertilizer.

Soak the seeds to germinate

Selecting the right seeds beforehand ensures good growth and improves efficiency. Hollow cabbage seeds are thicker and harder, so before sowing the seeds should be soaked to promote germination, soaked in warm boiled water for a period of time, so that the seeds can completely absorb the water. Encapsulated in damp gauze, and subsequently placed in conditions of 30 ℃, for this reason to promote germination.

Sowing

Dig a hole in the soil and sow the seeds, cover them with fine soil, spray them with water to maintain the humidity, and wait for them to germinate.

Care and management

Immediately after sowing the seeds, fertilize, spray water to maintain humidity, and keep them in full sunlight, and when the seedlings grow to about 17 centimeters, the tops can be removed to resolve the problem. After 30 days after sowing, when the hollow cabbage grows to about 35 centimeters, it can be picked.

Biological characteristics and planting characteristics

Hollow hearted cabbage, fibrous rootstock shallow, reconstructive function, stem nodes short oblate or nearly round, hollow, dense to light green. Cotyledons opposite, elliptic, out leaves **** born, long ovate, apical leaves cardiovascular or lanceolate, entire, leaf blade glossy, dense or light green. Leaves 13-17 centimeters long, 8-10 centimeters wide, leaf stems 12-15 centimeters long, hollow and concave. Seeds are sub-circular, thin-skinned, dark brown, and weigh 32-37 grams per thousand grains. Hollow cabbage to seed or young stem reproduction.

Cabbage prefer warm, hot and humid environment

Seed germination needs more than 15 ℃, trailing leaf growth preferred temperature of 25-30 ℃, higher temperatures, trailing leaf growth is more plentiful, the shorter the interval between harvesting time. Cabbage can withstand high temperatures of 35-40 ℃, 15 ℃ the following trailing leaf growth retardation, 10 ℃ the following trailing leaf termination of growth, not resistant to frost, frost leaves and stems that wither. Cabbage like higher air humidity and moist soil, the environment is too dry cane chemical fiber increase, take quality reduction. Hollow cabbage also like sunshine abundant, but the adaptability of sparse planting is also strong. Hollow cabbage to the more viscous, locking water and fertilizer efficiency of the soil is good, fertilizer, fertilizer tolerance, especially in the base fertilizer demand is relatively large.
