Master vegetable cultivation rotation skills to make your vegetables stable and high yield!

Vegetables are the same as field crops, reasonable crop rotation is also an important part of vegetable cultivation. It refers to in a certain number of years, in the same vegetable field, according to the predetermined type and order of vegetables for rotation. Thus, it can improve the soil structure, improve the soil fertility, reduce the harm of diseases, pests and weeds, increase the multiple cropping index, ensure the stable and high yield of vegetables and improve the economic benefits. The following basic rotation techniques should be mastered in cultivation.

The main results are as follows: 1. The vegetables with different absorption of soil nutrients and different root depth will rotate each other. For example, the leafy vegetables that consume more nitrogen fertilizer and the root vegetables that consume more potash fertilizer or the fruits and vegetables that consume more phosphate fertilizer, and the deep-rooted eggplant fruits, melons, beans and shallow-rooted leafy vegetables, onions and garlic rotation.

2. Rotation of vegetables that do not transmit diseases and insect pests, that is, the rotation of vegetables from different families every year, such as Solanaceae and Gramineae, Gramineae and Liliaceae.

3. Leguminous nodules can fertilize the soil, onions and garlic have a certain bactericidal effect, paddy fields can inhibit weeds in dry land, and rotation with the above-mentioned crops can improve soil structure, improve fertility and reduce the harm of diseases, pests and weeds.

4. Pay attention to the requirements of different vegetables on soil acidity, such as lotus white and potato can increase soil acidity after cultivation, later cropping is not suitable for planting acid-sensitive onion and spinach, while corn and pumpkin can reduce soil acidity after planting. Spinach, onion and garlic can be arranged, legume nodules leave more acid in the soil, continuous cropping often leads to reduced yield.

Generally speaking, leafy vegetables, green leafy vegetables, spring onions and leeks can be cropped continuously, but organic fertilizer should be applied. The intervals between potatoes, ginger, cucumbers and chili peppers should be 2-3 years; tomatoes, melons, peas and water melons should be 3-4 years apart; and watermelons should be 6-7 years apart.
