Mainly heat-resistant leafy vegetables with short growth period;

Such as Chinese cabbage, Chinese cabbage, summer cabbage, gourd, bitter gourd, Chinese cabbage, celery, dill, coriander, strawberry and many others can be planted.

Planting lettuce in summer:

1. Soil selection. Should choose fertile, rich in organic matter, strong water and fertilizer conservation, good air permeability, convenient irrigation and drainage soil for planting.

2. Variety selection. Lettuce varieties such as glass lettuce, bulbous lettuce, mosaic lettuce and Caesar are better.

3. sow and raise seedlings. The sowing date is generally from August to February of the following year, but the best sowing date is from the end of 10 to the middle of February of 12. In summer, sunshade nets or shade sheds can be planted.

In summer, small and high beds are generally planted, with a width of 70 cm, and two rows are planted in each bed, with a spacing of 25-30 cm. Planting can be done in sunny afternoons or cloudy days with soil. The best planting depth is that the clods are flush with the border surface and cannot cover the heart leaves. After planting, water it in time, cover the sunshade net and reduce the ground temperature. Covering the sunshade net should master the principles of covering during the day, uncovering at night, covering in rainy days and uncovering on cloudy days, so as to create suitable growth temperature for lettuce and prevent rain erosion. After slowly planting seedlings, intertillage and control water for 7- 10 days to promote rooting and prevent overgrowth, but never squat seedlings to affect yield. Summer cultivation, generally less intertillage, to prevent the ground temperature from rising. Surface weeding should be the main method for those who are not covered with plastic film. Weeding is usually done 2-3 times in the early growth stage. When the temperature drops, you can take off the sunshade or sunshade net and enter the natural growth state.
