What is the appropriate soil pH value for planting zelkova trees?

Nutrients such as phosphorus, calcium, potassium and magnesium are most easily absorbed by plants when the soil pH is in between. Under strong acidity (low pH) conditions, these nutrients are insoluble and relatively not easily absorbed by plants. However, some plants, such as rhododendrons, grow more vigorously in more acidic soils.

A high pH of the soil can also reduce nutrient absorption. When the pH of the soil is higher than 8, phosphorus, iron and many trace elements cannot be dissolved and cannot be absorbed by plants.

What are the types of requirements for soil pH?

The basic requirements of flowers for soil There are many types of flowers, which are suitable for their growth and development, and the characteristics of the soil are also very different.

In general, most flowers require humus-rich soil, loose and fertile soil, good drainage, and strong air permeability. The vast majority of open-field flowers require a pH of the soil to be around the limit, while greenhouse flowers require acidic soil.

1. The soil characteristics required by flowers The aggregate structure is good, and the drainage and ventilation aggregate structure is the size of the aggregate formed by the bonding of humus and mineral value in the soil. There are capillary pores inside the aggregate, which can store water and fertilizer, and there are large pores between the aggregates, which can be drained and breathable, and are not compacted after watering or rain.

The soil with poor aggregate structure is mostly heavy, compacted, and poorly drained, and the cultivation of flowers can easily lead to rot of flower roots, yellowing of leaves, and even drying and death. Humus is abundant and long-lasting, and humus is the organic matter formed by the decay of animal and plant residues and excrement.

The content of humus is abundant, and the content of available nutrients is abundant, which is conducive to the absorption of flower roots. The method of increasing the humus of the soil mainly relies on the addition of fully decomposed organic fertilizer.

The pH value should be suitable for most open-field flowers and most greenhouse flowers require acidic soil. A plant's adaptability to acidity and alkalinity in the environment is determined by the plant's root characteristics.

According to the adaptability of plant roots to environmental acidity and alkalinity, they are divided into: acidic soil plants; weakly acidic soil plants; near-neutral (acidic) soil plants; Weakly alkaline soil plants.

Beech trees do not have high requirements for soil, and are adaptable, as long as the soil is permeable and breathable, whether it is acidic, alkaline, neutral or mildly saline-alkali soil, zelkova trees can grow well.

The zelkova tree is a masculine species, light-loving and hardy.

Hope it helps.

Summary. Hello dear, zelkova trees only need to apply a small amount of organic fertilizer or farm fertilizer in the spring. Excessive fertilization can cause the root system of the plant to burn in the soil, resulting in root rot.

Beech trees are generally planted in spring, and the soil already contains fertilizer when planting, so there is no need to apply too much fertilizer.

Hello dear, beech trees only need to apply a small amount of organic fertilizer or farm fertilizer in the spring season. Excessive application of mid-skin fertilizer will cause the root system of the plant to burn in the soil, resulting in the phenomenon of root cavity rot. Beech trees are generally planted in spring, and the soil already contains fertilizer when planting, so there is no need to apply too much fertilizer.

In summer, it is necessary to apply fermented oil meal water or nitrogen and phosphorus fertilizer to zelkova trees at a concentration of 1 2 times every other week. The summer sleepiness key silver season is the period when the beech trees are bright and vigorous, and the amount of nutrients required is large, and it is necessary to apply fertilizer to improve the nutrients.

Nitrogen fertilizer can not be applied in autumn, and the amount of phosphorus and potassium fertilizer needs to be increased, which is conducive to the formation of lignified cherry blossoms and improves the cold resistance of plants. In autumn, it is not necessary to increase the growth rate of plant ridges such as celery branches and leaves, but only to increase the formation of xylem.

In winter, it is necessary to apply farmhouse fertilizer or organic fertilizer as the base fertilizer to return to brightness, and then apply potassium dihydrogen phosphate or superphosphate. Fertilizer only needs to be applied once in winter, which can provide effective and prudent filial piety for the plants and play a role in soil insulation.

Growth habits: Positive tree species or air dissipation, like light, like warm environment. It is suitable for growing in deep, fertile and moist soils, and has strong adaptability to soil, and can grow in acidic, neutral, alkaline soil and mild saline-alkali soil.

Deep-rooted, with wide lateral roots and strong wind resistance. Avoid stagnant water, intolerant of drought and barrenness.

Slow growth and long lifespan. Sowing and propagating, picking fruits in late autumn and storing them in the shade, sowing in early spring of the following year, soaking seeds with water for 1 2 days before sowing. Generally, strip sowing is used, with a strip spacing of 20 25 cm and a seed amount of 6 10 kg per mu.

In that year, the height of seedlings could reach 60 to 80 cm. Seedlings used for urban greening should be kept in the nursery for 5 8 years, and can only be planted when the dry diameter is about 3cm. Beech trees.

The roots of the seedlings are slender and tough, and the surrounding roots should be cut off with a shovel before digging to avoid tearing the root bark.

The fertilization time for red beech seedlings is as follows:

1. In spring, autumn and winter, top dressing can be often combined with watering, and fermented meal water or compound chemical fertilizer can be applied about once every 1 2 weeks. The concentration of chemical fertilizer should be about and should not be too concentrated, otherwise it is susceptible. The types of fertilization, different seasons should be emphasized, generally in autumn to apply some nitrogen fertilizer, such as soybean cake water, in order to facilitate the growth of leaves, and in winter and spring, apply more phosphorus and potassium fertilizers, such as hemp seeds, sesame, bone meal, etc., to facilitate the formation of leaf veins and the improvement of brightness.

In addition, potassium dihydrogen phosphate or superphosphate can also be used to spray the foliar surface for root topdressing, which can make the seedlings grow fast, draw more arrows, and have large flowers.

2. In autumn, nitrogen fertilizer should be stopped, phosphorus and potassium fertilizer should be increased to improve the lignification degree of plants and improve the cold resistance of seedlings. In winter, it is advisable to apply farmhouse organic fertilizer as base fertilizer, which not only provides effective nutrients for the growth of seedlings, but also plays the role of heat preservation and soil improvement. With the growth of seedlings, the amount of fertilizer should be gradually increased to meet the nutrient demand for seedling growth.

The amount of top dressing should be less for the first time, 2500g to 3000g of nitrogen fertilizer per mu, and then apply fertilizer every 15 days, and the amount of fertilizer can be slightly larger.

Red beech tree, also known as big-leaved beech, blood beech, chanterelle tree, etc., is a beech plant in the family Elmaceae. Red beech tree is a precious hard-leaved timber tree species in China, the material is hard and elastic, less elastic, not easy to warp, the texture is beautiful and shiny, the structure is fine, yellow-brown or light red. Strong pressure resistance, water moisture resistance, decay resistance, is used in buildings, bridges, vehicles and high-quality furniture; Its stem bark fiber is strong and can be used as a raw material for rayon ropes.

In addition, its canopy is conical, strong wind resistance, smoke and dust resistance, has a good windproof and air purification effect, and is also an excellent tree species for urban and rural greening and farmland shelterbelts. Due to the high economic value, especially the timber value, the red beech tree has become increasingly scarce due to excessive logging in recent years, and has been listed as a national second-class key protected plant.

When creating a general timber forest, use 1-year-old seedlings, and the size of the tree hole is 50 50 60 cm; The size of the tree hole for urban greening seedlings is 80 80 100 cm, and 10 30 kg of organic fertilizer is applied to the hole.
