How to manage Chinese toon seedlings? These key points must be mastered
Chinese toon is a tree-type vegetable, and its market price is very high. Right now is also the peak market season for Chinese toon, and market demand is relatively high. The edible part of Chinese toon is the young sprout, which contains very rich nutrients. When planting Chinese toon, the management work during the seedling stage is very important, directly determining the yield of Chinese toon. So how should Chinese toon be managed during the seedling stage? Let's take a look together below!
1. Remove the film in time
When sowing Chinese toon seeds, a layer of film needs to be covered to improve the soil's heat preservation and moisture retention. This can effectively improve the seed germination rate, but after the seeds germinate, emerge, and break through the soil, we must remove the film in time. This prevents some seedlings with poor soil-breaking ability from being unable to emerge. And if the film is not removed in time, it will also affect the seedlings' light absorption and affect their normal growth. So removing the film in time is the key to ensuring the normal growth of the seedlings, and after removing the film we should also pay attention to watering once to keep the soil moist and promote the seedlings' water absorption.
2. Thinning and final thinning of seedlings
After the seedlings emerge, their growth progress will differ due to various factors such as nutrients and weather. Therefore, when the seedlings grow to about 1-2 leaves, we should pay attention to doing the thinning work well, removing weak seedlings such as those with poor growth and pests or diseases. And they should be distributed evenly to avoid overly dense planting, keeping the spacing between healthy seedlings at about 4 cm. Then do the weeding work well, and combine it with fertilization, mainly diammonium phosphate. After watering thoroughly, shallowly hoe the soil once, and when hoeing the soil, pay attention to the force to prevent damaging the seedling roots.
3. Final thinning and transplanting
When the seedlings grow to about 3 true leaves, they can be appropriately singled out, and then until early June, when the seedlings grow to 5 true leaves. When they reach about 9 cm in height, they should be transplanted in time. This is because the nutrient conditions of the seedling bed can no longer meet the nutrients needed for the growth of Chinese toon seedlings. When transplanting, pay attention to controlling the plant and row spacing, keeping it at about 12-14 cm. Some weak and dead seedlings should be eliminated, and thick, strong seedlings should be retained. One day before transplanting, water appropriately to prevent the roots from being damaged during transplanting due to being too dry, then transplant in time, and water to promote survival.
4. Management after planting
After the Chinese toon seedlings survive, management should be strengthened, and fertilizer and water work should be done well according to the growth of the seedlings and soil fertility. Meet the nutrient and water needs for seedling growth, then weed appropriately to prevent affecting the normal growth of the seedlings. And in the middle and late stages of seedling growth, it is also necessary to do the pinching work well to prevent the central growing point from growing too strongly and causing excessive vegetative growth. Then appropriately spray agents such as paclobutrazol to inhibit the growth of the seedlings, control the plant height well, and adjust the tree shape of the Chinese toon tree. Improve the accumulation of nutrients in the tree body and promote the growth of the terminal buds.
The above is a brief introduction to the key points of Chinese toon seedling-stage management. The seedling-stage management work of Chinese toon is very important, and everyone must pay close attention to it, otherwise it will have a relatively large impact on planting benefits.
