When will the seedlings of Sapium sebiferum be transplanted?

1. Seedling grading

When raising the seedling, dig a circular ditch around the seedling plant, protrude the root system of the seedling plant, and then use a shovel to raise the seedling. Sapium sebiferum has strong vitality. If it is planted locally, there is no need to bring soil to the seedlings, and the seedlings planted in the garden are best planted along with them. The root system should be kept intact as far as possible, and the main root is about 25 cm long. Sapium sebiferum grafted seedlings can be divided into three grades. The height of the seedling is more than 150 cm and the ground diameter is more than 1.5 cm. The seedling height is 100-150 cm, the ground diameter is 1.0-1.5 cm, the seedling height is 70-100 cm, and the ground diameter is 0.6-1.0 cm. Different levels of seedlings are planted separately, which is beneficial to management. After raising seedlings, if they cannot be planted in time, they should be pseudo-planted immediately. When the seedlings are ready, you can choose a suitable site for planting.

2. Land selection and preparation

The soil adaptability of Sapium sebiferum is particularly strong, and it can grow on red loam in low mountains and hills, yellow loam in mountains, or saline-alkali land with a salt content of less than 0.3% for mountain afforestation or shelterbelt. As long as the pH value of the soil is between 5 and 8.

3. Retting fertilizer

We need to get the fertilizer ready before we open the hole. Sapium sebiferum trees like to use organic fertilizer as base fertilizer. We prepare 1000 kg of farm organic fertilizer and add 100kg of calcium superphosphate. It would be better if we mix some lime of 20kg. Mix these fertilizers and stir well. After mixing, cover the compost with plastic film and ferment for 10 days. When the retting is done, you can open a fixed planting point.

4. Opening holes

Before digging the hole, we marked the planting point and measured the size. The density of afforestation is 3 meters between plants and 4 meters between rows. Do not open the hole until it has been measured. Planting holes are generally square, with a depth of 60-70 cm. It is required that the topsoil and soil should be separated and stacked in an orderly manner, with a width and length of 80-100 cm, and the planting hole should be opened, followed by the application of base fertilizer.

5. Planting with base fertilizer

Before planting, the prepared fertilizer is applied at the bottom of the hole. We prepare 20-30kg fertilizer for each planting hole, and then mix the soil evenly. After filling, apply fertilizer for the second time, return to the soil and mix well. When the soil is returned to 5-10 cm above the ground, put in the seedlings. At this time, another person is needed to hold the seedling. The person who helps the seedling will lift the seedling up and cover the soil, which is conducive to the expansion of the root system during growth. It is also necessary to build a round tree plate with four sides high and low in the middle on the planting hole. To facilitate the pouring of root water. The root water must be watered thoroughly this time. Each seedling is drenched with 50 kg of water. Water again in three days. Because Sapium sebiferum trees are large, planting Sapium sebiferum trees in gardens is generally the most suitable for planting about 30 trees per mu. If it is interplanting, it is OK to plant 15 plants per mu.

What are the seedling raising and afforestation techniques of Sapium sebiferum?

1. Sowing and raising seedlings

(1) selection of nursery land. The land with gentle topography, deep soil layer, loose and fertile, good drainage and sufficient light is selected as the seedling land, and the mountain nursery can choose the gentle slope with good water and fertilizer conditions to make the bed along the contour line.

(2) to prepare the ground and make the bed. Turn deeply once in the winter of the first year, combined with the application of ferrous sulfate 30~45kg/hm2 for soil disinfection. In order to control underground pests, carbofuran 15kg/hm2 can be used for soil treatment. At the same time, the rotten farm manure 15t/hm2 was used as base fertilizer, and the border bed was made into east-west direction after ploughing and harrowing. The seedling bed was 15~20cm high and 1.2m wide.

(3) seed treatment. The seeds of Sapium sebiferum mature from October to November and can be harvested when the black-brown shell naturally cracks and the white seeds are exposed. The harvested fruit is dried and stored after threshing, impurity removal and drying. The outer skin of Sapium sebiferum seeds is waxy and it is difficult to absorb water and germinate, so it is necessary to carry out degreasing treatment before sowing. The method is to put the seeds into a container, soak them in hot water of 50: 60 ℃ and detergent, stir them while pouring water, let them cool naturally, then soak for 24 hours; after the outer wax skin of the seed is soft, scrub the seed coat waxy, and then wash the seed clean. After disinfecting the seeds before sowing, the seeds can be soaked with 0.5% potassium permanganate for 2 hours; spring sowing must be accelerated, but autumn and winter sowing need not.

(4) sowing seeds. Generally sowing in the spring and autumn 2 seasons, such as in order to avoid busy agriculture can also be sown in winter. When sowing, open a sowing ditch perpendicular to the seedbed to 10cm wide, the furrow distance is 20~25cm, the plant distance is 10cm, sowing on demand or sowing, the sowing rate is 112.5kg/hm2, and the soil is covered with 1~2cm after sowing.

(5) Seedling emergence and seedling management. After sowing, the water management of the nursery was strengthened, and the seedlings were unearthed after spring sowing for about 50-75 days. During the growth of seedlings, the weeding was strengthened by ploughing and weeding, which was usually carried out 3 or 4 times a year. When the seedling height reaches 10cm, the seedlings should be interspersed, fixed and replenished in time according to the requirements of row spacing. At the same time, the tending and management measures such as fertilization, irrigation and pest control should be strengthened to promote the healthy growth of seedlings. Generally, the seedling height can reach 60~100cm in the same year, and the seedling can produce 18 ~ 225000 plants / hm2. After falling leaves in autumn, you can go out of the nursery for afforestation.

2. Grafting and raising seedlings

(1) scion collection. The scion should choose the strong fruiting branches of one to two years in the middle and upper part of the crown of the mother tree as scions, and the seedlings of one to two years as rootstocks, and the thickness should be above 1cm. The main varieties of Sapium sebiferum in southern Shaanxi are grape tallow and chicken tallow. The scion was picked in early spring, sealed with wax and stored in a cool place indoors. (2) grafting and post-grafting management. The cutting method is commonly used. When grafting, cut off the rootstock at 5cm from the ground, and flatten the cut, and then cut the scion into 3~5cm with more than 2 full buds. One side of the scion is cut into a 2.5cm long left and right slope, and a small slope with a 45 °angle and a long 0.8~1.0cm is cut on the back tip of the slope, then the length of 3cm is cut vertically on the smooth side of the rootstock, reaching to the xylem, and then the scion is inserted inward into the rootstock incision to align the two cambium (for example, the rootstock notch is larger than the scion notch, at least one side of the cambium is dense), and finally wrap it with plastic strips. The best time for grafting is spring, which is usually carried out before and after waking. After the grafting survived, only one stout shoot was retained, the rest was erased, and the sprouts on the rootstock were removed in time.

3. Afforestation technology

The main results are as follows: (1) Sapium sebiferum, which likes light, warm climate and deep and fertile soil, has a certain ability to resist drought, moisture and wind, and can withstand intermittent flooding. It is often planted on the edge of fields and streams, and it can also be planted in the wind shield of mountainous areas. It can adapt to a wide range of soil, can grow on sandy soil, clay soil and gravelly loam, and can adapt to acid soil, calcareous soil and saline-alkali soil with salt content less than 0.25%. Sapium sebiferum can shoot three times a year, the main root is well developed, the wind resistance is strong, and the growth rate is fast.

(2) Sapium sebiferum seedlings can grow about 1 meter high and vary in diameter from 0.5 centimeters to 1 centimeters in diameter. They should be planted according to one row, with a row spacing of 40 centimeters. The following spring, cut off 10 centimeters above the root, the stubble can grow more than 2 meters in height, and the tree stem is straight, after the stubble should be fertilized and managed diligently.

(3) planting for one year, stubble for one year, planting separately in the third year, and the row spacing should be determined according to the sale plan. It takes 5 to 8 years to cultivate high-quality Sapium sebiferum seedlings, and the time is long and the return is high. At present, there are not many fine Sapium sebiferum seedlings that can be bought, and now there is a bright future for development. Insect pests include silkworms, diamondback moths, coir moths and other larvae that eat leaves and twigs, so attention should be paid to prevention and control.
