Seed prices and planting methods

Gleditsia sinensis is a unique plant in China, which is a deciduous tree of the genus Leguminosae. It is widely distributed in all parts of our country and has a wide range of uses. the seed oil can be used as a lubricant and make soap. It has the effect of treating ringworm and defecation. The wood material is a fine tree for making furniture. It is also very suitable for shade trees and greening trees around. Let's take a look at the seed price and planting method of Gleditsia sinensis.

How much is the seed of Zaojiao tree per jin?

The price of Gleditsia sinensis seeds is about 40-70 yuan per jin, but it varies greatly due to the quality, variety, producing area and market of the seeds. Zaojiao trees are mostly born in plains, valleys and hilly areas, like light but slightly resistant to shade, like warm and humid climate, do not have strict requirements on soil, can grow normally in calcareous, saline-alkali and even clay or sandy soil, and grow slowly but have a long life span of up to 600 to 700 years. Seeds are commonly used in production.

Sowing method of Gleditsia sinensis

The main results are as follows: 1. Seed collection: the 30-year-old 100-year-old mother tree with straight trunk, rapid growth, good development and full seeds was collected in the middle and late October. The fruits should be spread out and exposed to the sun, and the pods should be smashed or crushed after drying. The seeds are dried and bagged.

2. Seed treatment: the seed bark of Gleditsia sinensis is thick, and its germination is slow and irregular. It is necessary to accelerate germination before sowing. The seeds can be put into human water at the end of autumn and the beginning of winter, and the seeds can be stored and germinated with mixed wet sand after they are fully absorbed. The seeds will be sown after the seeds are split in the next spring.

3. Soil preparation and fertilization: the seedling land of Gleditsia sinensis should choose a place with fertile soil and convenient irrigation for meticulous soil preparation, applying organic fertilizer of 3000kg to 5000kg per mu to build a flat bed or a high bed.

4. Sowing method: Gleditsia sinensis was sown with 10 × 15 seeds per 1 meter, covered with soil 3cm and kept moist after sowing. The seedling height was about 10 cm, and the 2-year-old seedlings were transplanted according to the row spacing of 0.5 × 0.5 m after defoliation at the end of autumn.

The planting method of Gleditsia sinensis

1. Garden selection: Gleditsia sinensis should choose loam or sandy loam with deep, fertile and moist soil as forest land, mountains and hills should be selected at the foot of the mountain with a small slope, and flat land and beach should be selected in places where water is not easy to accumulate. At the same time, there should be certain drainage and irrigation measures.

2. The method of soil preparation before afforestation is to provide a better living environment for Gleditsia sinensis. In order to improve the site conditions and improve soil fertility, the quality of soil preparation must be guaranteed, such as trenching or banded soil preparation. Large holes can be used for planting trees on four sides and sporadically.

3. Afforestation time: Zaojiao trees can be afforested in spring and autumn, but it is better to afforest in autumn and winter. Burrowing soil preparation should be carried out according to the size of seedlings before planting seedlings, and the specifications of holes are 30 × 30 × 20 cm or 60 × 60 × 40 cm.

4. Planting density: the density of Gleditsia sinensis should be determined according to the actual situation. The higher the density is, the higher the amount of thorns per unit area is, the better the economic benefit is, but it is also difficult to manage. After 3-5 years, the crown transition between trees can be considered to be dense and sparse to ensure ventilation and light transmission in the forest.

5. Planting method: properly trim the root system of the seedling before planting, "three buries, two steps and one lift the seedling" when planting, straighten the seedling, gently lift the seedling by hand when burying the soil to the root, then step on it, pour through the fixed root water after planting, and cover another layer of soil.

6. Intermediate ploughing and weeding: after transplanting, the seedlings of Gleditsia sinensis are selected to loosen the soil and weed in time on a sunny day, which should be shallow rather than deep, so as to avoid harming the roots of the seedlings and loosening the topsoil to let the sun shine. During the seedling period, the weeding was carried out 4 times a year, which was carried out in April, June, August and October, respectively.

7. Fertilization management: Gleditsia sinensis reasonably selects fertilizers according to soil nutrient status and tree species characteristics, the ratio of nitrogen, phosphorus and potassium is 3:2:1, basal fertilizer is applied before planting, topdressing 3-4 times a year, mainly ditch application and spreading, can be combined with ploughing and weeding at the same time.

8. Shaping and pruning: Gleditsia sinensis should trim the branches to make the structure and shape reasonable, regulate the growth and development of branches and balance the tree potential, and cut off the upright branches at the top in time combined with shaping and pruning. At the same time, the autumn shoots at the top of the branches should be cut off in time.

9. Pest control: the pests of Gleditsia sinensis include bean weevil and heart borer, and the main diseases are anthracnose, blight, powdery mildew, brown spot and so on.

① silviculture and control: Gleditsia sinensis strengthens tending and management, enhances tree resistance, prunes reasonably when there are diseases and insect pests, removes dead branches and fallen leaves caused by diseases and insect pests in time, and interplanting dwarf economic plants such as peanuts, legumes and medicinal materials to increase biodiversity.

② drug control: 1200 times of dichlorvos can be sprayed on soya bean weevil and heart borer, 100 Bordeaux solution can be sprayed during the onset of anthracnose, and 50% carbendazim wettable powder can be applied during the onset of blight, powdery mildew and brown spot.
