What fertilizer do fruit trees need to be applied, and what fertilizer should be used for fruit tree

Fertilization principles: First, increase the application of organic fertilizer, long-term application of livestock and poultry organic fertilizer orchards to use high-quality compost or biological organic fertilizer, advocate organic and inorganic application; According to soil fertility conditions and yield levels, the amount of nitrogen, phosphorus and chemical fertilizers should be appropriately adjusted; Pay attention to the combined application of calcium, magnesium, boron and zinc. The second is to combine with high-quality and high-yield cultivation technologies such as reasonable pruning, grass mulching, film mulching, natural grass and ridge formation, refer to the suitable fruit retention amount and soil fertility index to control the total amount of nitrogen and phosphorus fertilizer applied annually, and regulate nitrogen, phosphorus and potassium fertilizers according to tree potential and tree age.

The third is to pay attention to the autumn application of base fertilizer, the best time for orchard base fertilizer autumn application is mid-September - mid-October, late-maturing varieties can be applied quickly after harvesting, and the application method is to take the ditch method or hole application. Fourth, orchards with soil acidification can improve the soil by applying soil conditioners, silica-calcium-magnesium fertilizer or hydrated lime.

From late March to early April, organic fertilizers such as well-rotted manure and soil miscellaneous fertilizer should be applied to fruit trees that have not been applied in autumn. Generally, mature fruit trees, such as pears, apples and other fruit trees, apply 60-100 kg per big tree, and each tree is mixed with 0 50-1 kg of urea, and spray new high-fat film solution at the same time to improve the absorption and utilization of fertilizer, so as to promote neat flowering, vigorous growth of new shoots, and improve fruit setting rate.

How to match the base fertilizer of apple trees in autumn? (apple tree base fertilizer, fertilizer, fertilizer, weak tree, strong tree).

Fruit trees need to use different fertilizers according to their growth stages, before planting to mix enough organic fertilizer as a base fertilizer, the early stage of growth is to use nitrogen fertilizer as the main fertilization raw material, the flowering and fruiting stage to apply phosphorus and potassium fertilizer to protect flowers and promote fruits, and appropriately add some trace elements to supplement it.

1. Base fertilizer application

Before the fruit trees are planted in the soil, it is necessary to prepare the fertilizer and nutrients used for it, that is, to add enough basal fertilizer to the soil, considering the receptivity of young plants, it is best to use organic fertilizer-based fertilizer, take the method of burying the soil to apply, and appropriately add some slow-release fertilizer as a supplement.

2. Fertilization at an early age

When fertilizing juvenile fruit trees, the main purpose is to ensure that the plant can grow tall and straight enough, can have a relatively large crown part, and the root system should grow thick and spread, so the main nitrogen fertilizer is used to promote the growth and development of branches and roots.

3. Fertilization during the flowering and fruiting period

In the flowering and fruiting period, the fertilization of fruit trees should take into account the growth and maturity of their fruits, so the fertilizer used should be mainly changed from the previous nitrogen fertilizer to the main nitrogen, phosphorus and potassium compound fertilizer, and the fertilizer used should be phosphorus and potassium fertilizer as the main component, so as to promote flowers and fruits, and strengthen flowers and fruits.

4. Fertilizer supplementation

In addition to nitrogen, phosphorus and potassium fertilizers and organic fertilizers, sometimes some fruit trees also need to add some trace elements, this is because some areas where fruit trees are planted, the organic matter in the soil is relatively small, and it is easy for fruit trees to lack trace elements, which need to be artificially added to ensure the quality and quantity of their final fruits.

Summary. Hello dear! Fertilizer for fruit tree fertilization:

1. Autumn fertilization: "autumn gold, winter silver, spring iron" illustrates the importance of base fertilizer and the urgency of time, generally buried at the end of October to the end of November, using open ring ditch, radial ditch, strip ditch and other ways to bury, adhere to the combination of organic and inorganic fertilizer, it is recommended to use "high calcium biological organic fertilizer and black tiger compound microbial ecological fertilizer, beneficial bacteria billion grams and chelated trace elements), which contains organic matter, humic acid, chelated trace elements and beneficial biological benefits, can help fruit trees recover tree potential as soon as possible, It lays a solid foundation for a bumper yield in the coming year, replenishes the organic matter content in the soil, and improves loose soil. 2. Spring fertilization:

It is recommended to use black tiger compound microbial fertilizer sulfur-based fertilizer, which can not only provide a large number of elements nitrogen, phosphorus and potassium, but also supplement the medium and trace elements required by fruit trees, reduce fruit tree deficiency disease, enhance the flowering and fruiting ability of fruit trees, and achieve the effect of flower and fruit preservation. 3. Fruit expansion period: At this time, the demand for fertilizer for fruit trees increases, because it is necessary to promote the expansion of fruits, increase the sugar content of fruits and improve the coloring of fruit surfaces.

Foliar fertilizer. It is recommended to use foliar spraying (alternately) with black tiger microbial agent and flying tiger Chinese herbal nutrient solution, which can increase the weight of single fruit, improve quality, reduce pests and diseases and degrade pesticide residues.

What kind of water fertilizer is used for pear trees and plum trees.

Hello dear! Fertilizer for fruit tree fertilization: 1. Autumn fertilization:

Autumn gold, winter silver, spring iron" illustrates the importance of applying bottom fertilizer and the urgency of time, generally at the end of October to the end of November for burial, the use of open ring ditch, radial ditch, ditch clear and other ways to bury, adhere to the combination of organic and inorganic fertilizer, it is recommended to use "high calcium bio-organic fertilizer and black tiger compound microbial ecological fertilizer, beneficial bacteria billion grams and chelated trace elements), which contains organic matter, humic acid, chelated trace elements and beneficial biological benefits, can help fruit trees recover tree strength as soon as possible, It lays a solid foundation for a bumper yield in the coming year, replenishes the organic matter content in the soil, and improves loose soil. 2. Spring fertilization: It is recommended to use black tiger compound microbial fertilizer sulfur-based fertilizer, which can not only provide a large number of elements of nitrogen, phosphorus and potassium, but also supplement the medium and trace elements required by fruit trees, reduce fruit imitation tree deficiency, enhance the flowering and fruiting ability of fruit trees, and achieve the effect of flower and fruit preservation.

3. Fruit expansion period: At this time, the demand for fertilizer for fruit trees increases, because to promote the expansion of fruits, increase the sugar content of fruits and improve the coloring of fruit surfaces, some fruit trees are also prone to fruit cracking and various physiological diseases. Foliar fertilizer.

It is recommended to use foliar spraying (alternately) with black tiger microbial agent and flying tiger Chinese herbal nutrient solution, which can increase the weight of single fruit, improve quality, reduce pests and diseases and degrade pesticide residues.
