What fertilizer should be applied to make old dead trees grow vigorously?

What makes trees grow quickly is organic fertilizer rich in nitrogen, phosphorus and potassium. Nitrogen fertilizer can make tree branches and leaves grow quickly, phosphate fertilizer can increase fruit yield and promote tree growth, and potassium fertilizer can improve the disease resistance of trees.

If you want to make the old dead tree grow more vigorously, you can eat some**, because ** will make the tree grow more nutritious and will make it flourish, so you can eat some potassium dihydrogen phosphate.

Generally, compound fertilizer can be used, potassium fertilizer first strengthens the root system, and nitrogen fertilizer raises leaves.

To make the old dead tree grow vigorously, it is best to recommend fertilizing fertilizer with sufficient energy, which can be more conducive to its growth and provide it with enough energy to make it grow healthier and stronger.

In fact, it should be the nutrient solution that is better, and you can add a little bit every time you water it, so that the growth is better and more vigorous.

It is very important to apply basal fertilizer, and the basal fertilizer is sufficient and can be applied less top dressing. The organic fertilizer made after full fermentation is suitable for the base fertilizer of potted plants. The usage is to mix one to three percent of the fertilizer in the culture soil, keep it moist, make the fertilizer and the soil fully integrated, and use it after 2 to 3 months in the winter or high temperature season.

According to different ingredients, they can be used for potting, potting or repotting of different flowers. Hoofhorns and poultry feathers are used as base fertilizers, which can be placed directly on the bottom of the pot when the flowers are potted. Soybean cake and other oil meal fertilizer and bone meal are used as base fertilizer in the same way as manure, and the dosage is 3% 5% when mixed into the culture soil.

When the flowers and trees are not repotted, they can also open a circular ditch along the edge of the pot when the flowers and trees are dormant, apply some fermented organic fertilizer, and then cover with new culture soil, which can also replace the application of base fertilizer. Inorganic fertilizers such as phosphate fertilizer can use superphosphate and phosphate rock powder, nitrogen fertilizer can use ammonium sulfate urea, potassium fertilizer can use potassium sulfate and potassium chloride, and two weeks ago mixed into the culture soil as base fertilizer.

The effect of dead leaves directly used as fertilizer is equal to zero, and the following methods need to be used to make fertilizer:

Dig a pit and pile up dead leaves in it and bury it.

Use tree branches to create a support structure around the pit to allow air to circulate.

It's better to turn it over after a few weeks, and you can get a few earthworms in.

If you want better nutrition, you can also bury some rotten vegetable leaves, peels, bones, fish bones or something.

Just put it in a pile, put some water, and rot the leaves.

1. Purging of leaves and weeds. In general, leaves and weeds are high in nitrogen. Such as fresh poplar leaves, nitrogenous fresh elm leaves, fresh locust leaves, fresh purple locust leaves, fresh dogtail grass, fresh Xanthus, fresh thorns, fresh mixed weeds.

Fresh leaves and weeds should be dried for half a day, and then 30 of the amount of fresh grass should be added to the fine soil. When making, a layer of raw materials can be spread on the spot, sprinkled with a layer of human feces according to the amount of raw materials in the layer of 10, and then sprinkled with a layer of 2 3 inches thick fine soil, layer by layer to 5,000 6,000 pounds, sealed with mud outside, soaked for 30 35 days, smash the compost pile and then seal it, and the fertilizer will be completely decomposed after 50 days.

2. Crop straw making. Sun-dried corn, sorghum, wheat, straw and other straws contain an average nitrogen. Because the crop straw contains high cellulose and cuticle, it is not easy to rot, so the "three-in-one" method of straw, manure and fine soil can be used when making fertilizer, and the proportion of the three is:

60% straw (1 day before soaking with water), 1000 well-rotted manure, 30% fine soil, when making, first lay a layer of 3 5 inches thick soil, then spread a layer of 1 foot thick dry stalks, and sprinkle about 1% lime water and ammonia to supplement the nitrogen source required for microbial activities and adjust the pH in the compost pile. Then spread a layer of 3 4 inches thick manure (donkey, horse manure is the best), pile up in turn, 5,000 6,000 pounds per pile, seal with mud outside, turn over the compost pile in about 40 days, splash an appropriate amount of water, continue to make after mud sealing, and then after about 20 days can be decomposed.

3. Preparation of aquatic plants in lakes and rivers. The average nitrogen content, phosphorus and potassium content of aquatic weeds is equivalent to 24 kilograms of ammonium sulfate, 20 kilograms of superphosphate, and 13 kilograms of potassium sulfate per kilogram of fresh grass. The proportion of raw materials is 30% finely crushed dry lake mud, 60% dried aquatic weeds, and 10% manure or donkey and horse manure.

Use these raw materials to pile up a layer of lake mud, a layer of aquatic plants, and a layer of manure, and the mud seal is drunk, and it is manually turned over once after 1 month, and then the mud is sealed for about 20 days to rot.

4. The preparation of fishy fertilizer in the lake and sea. The main raw materials are lake snails, clams and other animals. Most of the nitrogen contained in this kind of fishy fertilizer is protein, and phosphorus is mostly organic phosphorus, which can not be directly absorbed by crops, and must be converted into fast-acting nitrogen and phosphorus by microbial decomposition through fermentation before being absorbed and utilized by crops.

The method of making the fishy fertilizer of the lake and the sea is: first, the collected snails and clams are pressed into a paste with stones, and the raw materials are made according to the ratio of 1 kg of fishy fertilizer and 2 3 kg of fine soil, and after mixing, put it into the pit of 3 4 cubic meters, splash a small amount of water on the top, and then seal it with mud, and it can be decomposed after 40 days.

Bury it in the soil near the roots of the tree.

Pile them tightly together, and after a long time, it's fine.
