Key points of seedling management of Toona sinensis

Toona sinensis is a kind of tree vegetable, its market price is very high. It is also the peak season for the market of Toona sinensis, and the market demand is also relatively high. The edible part of Toona sinensis is young buds, which is rich in nutrients. When planting Toona sinensis, the management of seedling stage is very important, which directly determines the yield of Toona sinensis. So how to manage Toona sinensis at seedling stage? Let's take a look at it with the editor.

1. Uncover the film in time

Toona sinensis seeds need to be covered with a film to improve the heat preservation and moisture retention of the soil. It can effectively improve the germination rate of seeds, but we should uncover the seedlings in time after the seeds germinate and break the soil. To prevent some seedlings from being unearthed because of their poor top soil ability. And if the film is not uncovered in time, it will also affect the light absorption of seedlings and affect the normal growth of seedlings. So even if uncovering the film is the key to ensure the normal growth of the seedlings, we should also pay attention to watering once after opening the film to keep the soil moist and promote the water absorption of the seedlings.

2. The seedlings are fixed

After unearthed, the growth process of seedlings will be different because of nutrition, weather and other factors. Therefore, when the seedlings grow to about 1-2 pieces, we should pay attention to do a good job of inter-seedling work and eliminate weak seedlings such as weak growth, diseases and insect pests. And should be evenly distributed to avoid planting too dense, the spacing between robust seedlings should be controlled at about 4 cm. Then do a good job of weeding, and combined with fertilization, mainly diammonium phosphate. After watering through the water, hoe the soil once, and pay attention to the strength when hoing the soil to prevent damage to the roots of the seedlings.

3. Fixed seedling transplanting

The seedlings can be properly fixed when the seedlings grow to about 3 true leaves, and then until the beginning of June, the seedlings grow to 5 true leaves. Transplant in time when it is about 9 centimeters high. Because the nutritional conditions of the seedling bed can no longer meet the nutrition needed for the growth of Toona sinensis seedlings. When transplanting, we should pay attention to control the row spacing and keep it at about 12-14 cm. It is necessary to eliminate some weak seedlings and retain strong ones. The day before transplanting, it can be properly watered to prevent excessive dryness from causing root damage during transplanting, and then transplant in time to promote living plants.

4. Post-planting management

After the survival of Toona sinensis seedlings, it is necessary to strengthen management and do a good job of fertilizer and water according to the growth of seedlings and soil fertility. To meet the nutrient and water needs of seedling growth, and then to weed properly to prevent the normal growth of seedlings. And in the middle and later stage of seedling growth, it is necessary to do a good job of coring to prevent the central point from growing too strong and overgrowing. Then appropriate spraying paclobutrazol and other chemicals to inhibit the growth of seedlings, control the plant height, adjust the tree shape of Toona sinensis. Improve the nutrient accumulation in the tree and promote the growth of the terminal bud.

The above is a brief introduction to the main points of Toona sinensis seedling management. The seedling management of Toona sinensis is very important, and we must pay more attention to it, otherwise it will have a great impact on the planting efficiency.
