What is vegetable Italy?

Feeding methods and matters needing attention

1, select high yield, high quality and disease-resistant varieties. Italian lettuce belongs to special vegetables, which has high commodity, good growth, heat resistance, disease resistance and bolting resistance.

2. sow at the right time? .

3. Seedling raising: seed amount 100 ~ 120g/ mu. The cultivated autumn lettuce is in the high temperature season. Germinate the seeds at low temperature before sowing, wrap them with emery cloth and soak them in cold water for 5-6 hours. Under the cold and wet conditions of 15 ~ 20℃, accelerate germination for 2 ~ 4 days, sow after germination, cover with sunshade net after sowing to prevent strong light and rain, sow evenly in time after two real leaves grow, with the seedling spacing of 3 ~ 4 cm, topdressing 2 ~ 3 times at seedling stage, and then plant 4 ~ 5 real leaves in the field? .

4. Fine soil preparation and application of base fertilizer: lettuce should be planted in fertile and loose soil, requiring fine leveling, with organic base fertilizer 1, 500-2,000 kg/mu and compound fertilizer 1.7 kg.

5. Reasonable close planting: Reasonable close planting is the foundation of high yield and high quality. Italian lettuce should be planted with 65,438+0,000 plants/mu, with row spacing of 40cm×20cm, and the best planting time is sunny and evening. Water frequently after planting to promote rooting and survival. [2]。

6. Timely fertilization: Italian lettuce has a short growth period and strict requirements for nutrients at each stage. Base fertilizer 1500 ~ 2000 kg/mu, compound fertilizer 17 kg. On this basis, the technical measures of "promoting before and controlling after" are adopted for topdressing, with nitrogen fertilizer applied in the early stage to promote growth, digging fertilizer in the middle stage to prevent futile growth, and applying chemical fertilizer in the later stage. But you can't water too much in the later stage to prevent soft rot. It can be harvested and put on the market 30-35 days after planting.
