A Detailed Guide to the Latest Planting Time and Methods for Tatsoi
Tatsoi is a high-quality crop with edible and ornamental value, one of the main vegetables in winter, and one of the more popular vegetables. So when is the best time to plant tatsoi? How should it be planted? Let's take a look.
1. Planting time
Tatsoi has extremely strong cold resistance, and its growth period is generally about 70-80 days. The suitable growing temperature is between 10-25 degrees, and it can be planted for most of the year. The autumn sowing time is generally in August-September, when the temperature allows direct open-field cultivation. If planting in winter, it can be brought to market before the Spring Festival for better returns, and is generally sown around November.
2. Variety selection
The choice of tatsoi variety should be determined according to local soil, climate and other conditions as well as the planting time. If autumn sowing is chosen, it is best to select varieties with strong cold resistance, late bolting time and strong market quality. For example, Shanghai Small Eight-Leaf and Medium Eight-Leaf are both good varieties.
3. Selection of planting site
Before planting tatsoi, the plot needs to be plowed and fertilized. Deeply plow the soil about 15 cm, and apply fertilizer according to the actual fertility of the soil. Apply 3000-4000 kg of decomposed organic fertilizer per mu, together with 5-8 kg of urea, about 50 kg of superphosphate, and about 12 kg of potassium sulfate. After fertilizing, prepare the land according to the terrain. For higher ground, make beds; for lower ground, form ridges.
4. Sowing and seedling raising
Tatsoi can be either direct-sown or raised as seedlings and then transplanted. For autumn open-field cultivation, the direct sowing method can be used. After sowing, cover with about 1 cm of soil, and keep the soil moist before sowing. Tatsoi emerges extremely quickly, generally within about three days. After emergence, pay attention to thinning the seedlings in time to avoid excessive watering that causes the seedlings to grow leggy. Thin to a final stand 30 days after the seedlings emerge, keeping plant spacing at about 15 cm and row spacing at about 30 cm.
5. Field management
Tatsoi has a short growth cycle, and the number of fertilizer applications during the growing stage is also relatively small. Generally, after final thinning, apply one light fertilizer dressing, with about 8 kg of compound fertilizer per mu. Later, topdress according to the growth of the seedlings, each time with 5 to 8 kg of urea. The soil should be kept moist, but not too dry or too wet. In addition, pay attention to the prevention and control of pests and diseases. The pests and diseases of tatsoi are generally aphids, soft rot, whiteflies, etc. For insect pests, imidacloprid, acetamiprid, etc. can be used for control, while for soft rot, chlorothalonil and daconil can be used for control.
