Time and method of fertilization for vegetables in summer

Summer is a vigorous period for the growth of vegetables. There are many kinds of vegetables growing in summer, and the temperature in summer is also very high. The absorption of vegetables after fertilization will be different from other seasons. It is rainy and bright in summer, and these environmental factors will affect the fertilization time of vegetables. Specific aspects should also be changed according to these conditions, so differential fertilization is needed. For more details, let's learn about it.

1. Classified fertilization

The main common vegetables in summer are beans themselves with nodules, which can fix nitrogen fertilizer, but other fertilizers need to be supplemented, beans need calcium fertilizer, phosphate fertilizer, and potassium fertilizer is also needed for rhizome growth. Leafy vegetables need enough nitrogen fertilizer to ensure that the leaves are tender and green, with less potash fertilizer and more phosphate fertilizer. Root vegetables, mainly grow roots, so need a lot of potassium fertilizer, combined with the use of phosphate fertilizer, summer is the time to grow roots, so nitrogen fertilizer should be applied less. The root system of eggplant fruit is stronger than that of other vegetables, and summer is the main fruit period of fertilization. it is necessary to apply more phosphorus and potassium fertilizer and increase trace element fertilizer.

2. Temperature influence

Early summer temperature is low and warm is the appropriate time for fertilization, soil temperature is not so high, midsummer temperature increase fertilization is best combined with watering dissolved use, it is best to use after the afternoon, do not use chemical fertilizer, the use of a small amount should be carried out in stages. Don't apply less fertilizer in dog days, it's best not to apply fertilizer.

3. Weather influence

Sunny days, do not fertilize, fertilize in cloudy days, or fertilize after the afternoon, rainy days are very suitable for fertilization, but it is often heavy rain in summer, so do not apply fertilizer before the heavy rain, after the rain, the soil gradually dries up and can be fertilized later. If light rain does not apply fertilizer for days, the fertilizer will be washed away and the roots will not be able to absorb it. Or the root system absorbs too much water and the fertilizer is useless.

4. Use fertilizer

Generally use farm manure, livestock fertilizer, straw compost, vegetable leaf compost, a small amount of chemical fertilizer, no poultry fertilizer, high heat and damage to the root system. It is more suitable to use fertilizer with low heat after complete ripening treatment. The concentration of fertilizer should not exceed the concentration of soil solution, otherwise the fertilizer can not be absorbed.

5. Fertilization period

Eggplant fruits are in the fruiting stage in summer, mainly for fertilization to promote fruit and ensure plant nutrition. Legumes are mainly in the podding stage and need to ensure nutrition to avoid plant yellowing. Leafy vegetables, during the period of exuberant leaves, ensure that the fertilizer keeps up with the growth. Root vegetable fertilization should not be too prosperous, it is easy to crack the root.

Summer fertilization for vegetables is mainly based on the types of vegetables and environmental impact, to determine the specific amount of fertilizer, what kind of fertilizer. Also pay attention to the fertilization period, appropriate fertilization.
