Everyone should be familiar with vegetables and eat them every day. Vegetables have rich nutrients such as protein and amino acids. There are many kinds of vegetables, especially in the cultivation of vegetables, we must pay attention to the application of fertilizers of different vegetables.
The common types of vegetables are mainly leafy vegetables, fruits, and roots, and the fertilization methods used for each vegetable are of course different. Here are some tips on how to fertilize these three vegetables:
1. Fertilization of leafy vegetables
Leafy vegetables refer to vegetables that use the leaves and petioles of the plants as edible parts.
Characteristics: The planting density is large, mostly shallow root vegetables, so the demand for available nutrients in the soil is sensitive and urgent. If the nutrients are not supplied in time, the leaves will turn yellow and grow slowly.
Fertilization tips:
The base fertilizer is mainly applied with organic fertilizer, and the top dressing is mainly applied with quick-acting nitrogen fertilizer, combined with application of phosphorus and potassium fertilizer, and other elemental fertilizers should be properly applied;
The application of base fertilizer should be sufficient, and the topdressing should be reasonable: the slow-acting fertilizer should be added in the early and middle growth period, and the accelerated growth of ammonium bicarbonate should be carried out in the late growth stage;
Vegetables should be mainly applied with nitrogen fertilizer during the period of vigorous growth, and appropriate application of phosphorus and potassium fertilizer should be applied;
It is strictly forbidden to use organic fertilizer made from harmful municipal waste and sludge as raw materials. Fertilizer should not be used as top dressing during vegetable harvesting.
2. Fertilization of fruit vegetables
Fruit-based vegetables are vegetables that have a long growing period and that will bloom, with the plant's reproductive organs as the edible part.
Characteristics: The vegetative growth period and reproductive growth period of fruit vegetables are carried out at the same time, which takes a long time and requires a large amount of three elements.
Fertilization tips:
Seedlings need more nitrogen fertilizer, but excessive application of nitrogen fertilizer is easy to cause long, prolonging flowering results, leading to falling flowers and fruit;
During reproductive growth, the demand for phosphate fertilizer has increased significantly, but the demand for nitrogen fertilizer has decreased. Therefore, phosphorus and potassium fertilizers should be added to reduce the amount of nitrogen fertilizer;
The base fertilizer and top dressing of fruit vegetables are very important. The base fertilizer should be applied and the top dressing should be applied early. Immediately after the fruit is harvested, the quick-acting nitrogen fertilizer should be applied to promote the growth of the next wave of fruit.
3, root vegetables
Rhizome vegetables refer to vegetables that use the roots or tubers of plants as edible parts.
Characteristics: After the roots and vegetables are formed into a strong period, the leaves will gradually stop growing.
Fertilization tips:
It should be mainly applied with organic fertilizer, and the main fertilizer should be applied with phosphorus and potassium fertilizer, and combined with NPK;
Nitrogen fertilizer should be applied in the early stage of vegetable growth, and potassium fertilizer should be added in the middle and late growth stages, but the amount of nitrogen fertilizer should be reduced;
Control fertilization during flowering to avoid falling flowers, falling fruits and fallen leaves;
In the young fruit period and during the harvest period, it is necessary to topdress it in time to promote fruit enlargement;
It is strictly forbidden to apply high-concentration fertilizer, and the soil is prohibited from topdressing when it is wet. Concentrated fertilization is strictly prohibited.
