A Detailed Guide to the Off-Season Vegetable Planting Schedule

The planting time for each off-season vegetable is different. For example, summer and autumn spinach is sown from June to August; celtuce is planted from late July to early August; amaranth is sown in February.

Off-season vegetable planting techniques:

1. Build a greenhouse for management

Choose a flat area with a convenient water source and sufficient sunlight where the wind is not too strong to build a greenhouse, preferably in plains or hilly areas. Greenhouses are mainly divided into winter-warm greenhouses and spring-autumn greenhouses; winter-warm greenhouses are for winter planting, while spring-autumn greenhouses are suited for late autumn and early spring planting.

2. Land preparation and fertilization management

Before planting, first mix nutrient soil in the greenhouse, then apply organic and inorganic fertilizers along with land preparation. Pay attention to timing and method when fertilizing. Fertilizing should be done one month before planting, and pay attention to the amount of fertilizer applied when fertilizing. In addition, before fertilizing, it must undergo fermentation treatment, applying thoroughly decomposed fertilizer, so as to avoid fermentation in the soil producing toxic gases that harm the growth of lettuce.

3. Choose vegetable varieties

Not all vegetables can be grown as off-season vegetables; choose varieties that are cold-tolerant, highly disease-resistant and early-maturing, so as to reduce the impact of low temperatures on the vegetables, such as zucchini, tomatoes, peppers, eggplant, cucumbers, loofah and other vegetables.

4. Field management

After the vegetables are planted, promptly water them to help them recover from transplanting and maintain soil moisture; different vegetables have different water requirements. Control the frequency of watering and regularly loosen the soil and remove weeds. Also, promptly remove diseased and weak plants and strengthen pest and disease control work.

5. Heat preservation, moisture retention and cold protection work

The key point of off-season vegetable planting is to do a good job of heat preservation, moisture retention and cold protection. According to the situation, do a good job of maintaining soil moisture; regularly loosen the soil to prevent soil compaction; regularly spray foliar fertilizer to increase plant nutrition; regularly ventilate to reduce the emission of carbon dioxide and other toxic gases.

Off-season vegetable planting can not only ensure a year-round supply of vegetables, but also bring more income to growers, killing two birds with one stone.
