First, rational rotation of planting vegetables, full use of soil nutrients Different vegetables absorb different nutrients, the need for more nitrogen, the need for more phosphorus and potassium need more vegetables rotation, or deep-rooted vegetables with shallow root vegetables Rotation can make full use of nutrients at all levels in the soil. Second, pay attention to the prevention and control of pests and diseases Rational rotation of different vegetables, planting, can cause parasitic pathogens or change their living environment to achieve the purpose of reducing or eliminating pests and diseases. Such as cucumber wilt, aphids, etc. can also invade other melon vegetables. If you change other kinds of vegetables, it will reduce or eliminate the effect of pests. Another example: After onion, garlic harvested after the kind of cabbage, can significantly reduce the soft rot. If food and vegetable crop rotation is implemented, the rotation of paddy and dry crops is more effective in controlling soil disease in the soil communication room. Third, pay attention to the impact of various vegetables on soil pH and fertility Potatoes, cabbage, etc. will increase soil acidity, and corn, pumpkin, etc. will reduce the acidity of the soil; Therefore, the acid-sensitive onions as corn, pumpkin after use, can With high yield, leguminous vegetables can increase soil organic matter content and increase soil fertility. Long-term planting of leafy vegetables that require more nitrogen will make the nutrients in the soil unbalanced and lead to a deficiency of vegetables. Therefore, it is necessary to properly grow and grow the vegetables with a long growing period and a short growing period, which require more fertilizer and less fertilizer. Fourth, pay attention to the inhibitory effect of previous crops on weeds Some rapid growth or planting density, long growth period, large leaf coverage on the ground, vegetables, such as melon lamps, cabbage, beans, potatoes, etc., have obvious inhibition of weeds The role of carrots, celery, etc., slow seedlings, small leafy vegetables, easy to breed weeds, the rotation of these vegetables planted, can significantly reduce the damage.
