What are the basic principles of vegetable rotation that must be mastered?

Rational rotation of different vegetables can not only eliminate the parasitic environment of pathogenic bacteria, but also achieve the purpose of reducing or eliminating pests and diseases. At the same time, it can also increase production and income. Let’s take a look!

1. After planting onions and garlic, plant another crop of Chinese cabbage, which can reduce plant diseases, reduce the use of drugs, and increase income.

2. Vegetables in the same family should not be rotated. For example, tomatoes, eggplants, peppers, and sweet peppers belong to the Solanaceae family, so they are not suitable for rotation.

3. Vegetable farmers must not plant cucumbers and tomatoes next to each other, or plant tomatoes after planting cucumbers. They inhibit each other and will reduce production.

4. Tomatoes can be intercropped with edamame, cabbage, bulb fennel, onions, garlic, etc. in separate borders. At the same time, interplanting tomatoes and side vegetables in autumn sheds can lower the ground temperature. Interplanting sweet corn with tomatoes can induce moths to lay eggs, achieve the purpose of centralized elimination, ensure production and increase income.

5. Eggplant can be interplanted with short-growing vegetables such as early cabbage, early-maturing cabbage, spring radish, water radish, and cherry radish, and autumn vegetables such as Chinese cabbage can be planted in the subsequent crop.

6. Peppers should not be continuously cropped with Solanaceae crops or intercropped with leafy vegetables, root vegetables, peanuts and other short-stem crops.

7. Rotating melons and leafy vegetables for 3 to 5 years can significantly increase production.

8. The first carrot crops in autumn and winter are mostly wheat, spring cabbage, spring cabbage, beans, etc. Subsequent crops can be inoculated with wheat, onions, spring cabbage, green onions, potatoes, etc.

9. Potatoes: The first crops are onions, garlic and cucumbers, followed by cereal crops and soybeans.

10. Green onions: Use green onions to cultivate Chinese cabbage and melon vegetables. Plant early-maturing radish during the period before green onions grow, and interplant with spinach and other overwintering crops in the later period.

11. Chinese cabbage and Chinese cabbage: can be rotated with melons, beans, root vegetables and field crops. Spring-planted vegetables can be interplanted with nightshades, beans, melons, etc.

Summer and autumn vegetables can be mixed with celery, chrysanthemum and carrots. In early autumn, cabbage can be interplanted with cauliflower, cabbage, autumn potatoes, etc. Intercrop with spring cabbage, lettuce, etc. in winter.

12. Shepherd's purse: The best first crop for autumn sown shepherd's purse is tomatoes and cucumbers; the first crop for spring shepherd's purse is garlic. Avoid continuous work.

13. Winter melon: 5 to 6 ginger plants are planted between the winter melon plants, kudzu is planted on one side of the border, and taro is planted on the other side. After April and May, winter melons or peppers and eggplants are interplanted with winter melons in the leek beds; winter melons are interplanted with tomatoes; bulbs, fennel, lettuce, cabbage and leafy vegetables are interplanted under the winter melon trellis; in mountainous areas, winter melons are interplanted with ginger.

14. Watermelon: Crop rotation for more than 5 to 8 years. Rotating crops include: wheat, rice, corn, radish, sweet potato and green manure.

15. Lotus root: Lotus root and rice are rotated. After the early lotus root is harvested, cress, wild rice, water chestnuts, and watercress can be planted. Lotus root is often rotated with wild rice, water chestnuts, and wild rice every other year, or intercropped with wild rice.

16. Lettuce: You can plant onions, garlic, and cucumbers in the front, and you can plant strawberries and tomatoes in the back.

Crop rotation, intercropping, and continuous cropping: three principles

1. Leafy vegetables generally require more nitrogen, and it is best to arrange solanaceous vegetables that require more phosphorus in subsequent crops. . Cucumbers, celery, and spinach that absorb fertilizer quickly are best grown in the next crop, and tomatoes, eggplants, peppers, etc. that absorb more organic fertilizer are best.

2. Pay attention to the impact of various vegetables on soil pH. Planting potatoes and cabbage will increase soil acidity, while planting corn, pumpkin, etc. will decrease soil acidity. Therefore, allium vegetables that are sensitive to acidity can achieve high yields as subsequent crops of corn and pumpkin.

3. Vegetables with long and short growth periods, and vegetables that require more and less fertilizer should be planted in a reasonable combination. Planting legumes and vegetables can increase the organic matter content of the soil and improve soil fertility. However, long-term planting of leafy vegetables that require more nitrogen will cause the nutritional elements in the soil to lose balance.

Crop intercropping is actually very popular. Reasonable intercropping can increase production and income. It is indeed worth trying. However, it is necessary to find out whether the two are incompatible before planting, otherwise it is easy to lose more than the gain.
