When is the best time to fertilize trees?

Autumn application is best applied before and after the autumn equinox, when the root system is at another peak of growth, and it is easy to heal after the root is injured, and new roots can be generated; Organic matter also takes longer to decay and decompose, which can provide nutrients for tree growth in the following year. Spring application of basal fertilizer, if the organic matter is not fully decomposed, the fertilizer effect is slow, early spring can not supply the root system to absorb, to the late growth of the fertilizer effect to play a role, often cause the secondary growth of new shoots, especially the growth and development of the tree is not conducive to the flower bud differentiation and fruit development. 3. Application period of top dressing:

When trees need fertilizer urgently, fertilizer must be supplemented in time to meet the needs of tree growth and development. The specific topdressing time is related to the tree species, variety habits and climate, age, use, etc., and it is necessary to carry out topdressing strictly according to the characteristics of each growth period, such as the topdressing of flowering and fruiting trees, the flower bud differentiation period and the topdressing after flowering is more important. For most garden trees, topdressing during the peak growing season of the year is essential.

The number of topdressing, for the flowering trees, shade trees, street trees and key ornamental tree species within 2 to 3 years of initial planting, it is necessary to carry out topdressing 1 2 times a year during the growth period. As for the specific period, it must be reasonably arranged and flexibly grasped according to the situation. When the tree has symptoms of fertilizer deficiency, top dressing can be carried out at any time.

There are five periods of fertilization for fruit trees.

1. Autumn base fertilizer: This period is the third growth peak of fruit trees, which is generally carried out in October, with comprehensive nutrient requirements and can provide nutrients evenly and for a long time.

2. Germination fertilizer, pre-flowering fertilizer: 2-4 weeks before germination, this period is the first growth peak of the root system of fruit trees, the tree body mainly consumes stored nutrients, and the fast-acting nitrogen fertilizer is the main fertilizer, which can improve the fruit setting rate and the uniformity of the branches.

3. Fruit-preserving fertilizer, flower bud fertilizer: used when the new shoots stop growing, usually in early June, nitrogen, phosphorus, potassium, and micro-supplementation.

4. Fruit expansion fertilizer: the fruit expands rapidly, and the new shoot growth stops when it is used, this period is the second growth peak of the fruit tree, which is generally carried out in July; The purpose is to enrich the new shoots, promote fruit expansion, improve fruit quality, and promote the continuous differentiation of flower buds.

5. Post-harvest fertilizer, yang fertilizer: the fruit is used after harvesting, mainly nitrogen fertilizer, and phosphorus and potassium fertilizer.

There is a proverb in agriculture, "Autumn fertilizer is gold, winter fertilizer is copper, and spring fertilizer is rotten iron." "Autumn is the best time of year to apply fertilizer.

The fertilization period is also different for different trees. Generally, fertilizer is applied once every half month, and fertilizer needs to be applied during the peak growing season and the flowering and fruiting period. Try to avoid rainy days and dry soil fertilization.

Hello, a few suggestions for you are as follows:

Autumn foundation is the most important thing to lay a good foundation. Autumn is also the time of year when the nutrients begin to absorb the reserves after the harvest of the fruit trees. Generally, after the tree falls leaves and is implemented before freezing, it is mainly rotten farmhouse fertilizer, and compound fertilizer can also be applied without this condition, and the amount can be determined according to the size of the tree and the amount of hanging fruit.

Before and after Qingming, top dressing. Mainly in the sea and Weihai fertile nitrogen fertilizer, because the liquid nitrogen consumption of the tree after flowering is serious, if the nitrogen is not replenished in time, it will fall flowers and fruits, and the irrigation conditions can be topdressed with water

1. Fertilization is applied according to different tree species and different growth periods, nitrogen is the main one in the long leaf stage, and phosphorus and potassium are the main ones in the flowering and fruiting stage.

2. Apply less in the dormant period, apply basal fertilizer before tree germination, and apply water-soluble fertilizer to fertile leaves in the later stage.

In fact, it mainly depends on what tree, the difference is too big, it is not easy to generalize.

Generally, fertilization is applied at the stage when the tree is more vigorous, and the tree grows more vigorously from March to September, so you can choose this time period!

If it is a newly planted seedling, it is not suitable to fertilize immediately after planting. After the seedlings survive (manifested as growing new roots and sprouts) there are 2-3 new leaves, organic fertilizer can be applied thinly, and fertilizer topdressing can be carried out after the seedlings grow normally, a small number of times, and the normal dose of topdressing can be carried out regularly after the growth enters the vigorous period, generally 25-30kg mu.

1. Planting time.

Poppies prefer warm growing conditions, and the best time to sow seeds is in spring or autumn. It depends on the region, but in the northern region, the best time to sow seeds is in the spring, so that the flowers will bloom around July after planting. If you are in a warm region in the south, you can choose to sow seeds around September to October in autumn, so that the flowers will bloom around April in the following spring.

Second, land selection and land preparation.

Poppies are very light-loving plants, and in order to ensure their normal growth, they should choose a plot with plenty of sunlight and easy drainage. It is best to plough the land once before planting to ensure that the soil is soft and delicate, which is conducive to the later germination of seeds.

3. Sowing method.

Poppy seeds are relatively small, and it is best to water them thoroughly before planting to avoid watering and washing away the seeds after planting. It is best to mix the seeds with the sand before sowing and then spread them on the surface of the soil. After the seeds are sprinkled, cover them with a thin layer of soil so that the seeds will sprout quickly.

Summary. It is best to fertilize during the growth period of trees, generally in spring and autumn, so as to ensure that the trees have enough nutrients when they grow, and the trees can grow better and faster.

When is the best time to fertilize the tree.

It is best to fertilize during the growth period of trees, generally in spring and autumn, so as to ensure that the trees have enough nutrients when they grow, and the trees can grow better and faster.

What fertilizer to apply in the autumn season of greening big trees.

Autumn is generally the peak period for tree root growth, and it is generally suitable to apply some nitrogen, phosphorus and potassium compound fertilizers.

1. When is the best time to fertilize trees.

2. The best time for tree topdressing.

3. What season is it good to fertilize trees?

4. The best time to fertilize shrubs.

1.The best time to fertilize trees is during the growing season, and when basal fertilizer is applied, it is mostly done in spring and autumn.

2.When top dressing, that is, when it grows relatively fast, the tree generally does not need to be fertilized when it is dormant.

3.If it is a fruit tree, it is necessary to carry out top dressing in the spring germination, flowering and fruiting periods, mainly nitrogen fertilizer during the budding period, and phosphorus and potassium fertilizer during the flowering and fruiting period.

Fertilization can be applied all year round. In order to better achieve the purpose of fertilization, Oasis puts forward the following suggestions:

1. Because the absorption of nutrients and water is all in the fibrous roots, fertilization should be around the roots, not close to the trunk.

2. For trees with strong roots and far-reaching distribution, fertilization should be deep and large; Trees with shallow root systems should be fertilized shallowly and the range should be small.

3. Nitrogen fertilizer is highly mobile in the soil, and shallow application can penetrate into the root layer and be absorbed by trees; The mobility of potassium fertilizer is poor, and the mobility of phosphate fertilizer is even worse, so it should be applied deeply to the most distributed root system.

4. The basal fertilizer effect is slower and should be applied deeply, and the top dressing fertilizer effect is faster, so it should be applied shallowly. However, it is recommended that after fertilization, it is necessary to irrigate the fertilizer in time to stimulate the fertilizer to penetrate into the soil.
