When it comes to transplanting seedlings, which time is better in autumn or spring?

Nowadays, seedling greening has become a bright spot of development, and the number of economic forests such as gardens is also increasing, and the development is always good, but the key point is to carry the seedlings alive first, and the important thing to transplant seedlings is how to choose the right time. Many people understand that autumn and spring are important times for transplanting seedlings, but that season can better improve the survival rate of seedlings.

Transplanting seedlings in autumn: there is still plenty of sunshine in autumn, and there is still a lot of heat radiated to the ground, which can greatly increase the soil temperature and promote the activity of soil microorganisms. if transplanting in autumn, soil temperature can accelerate the activity of seedling roots, can quickly adapt to the soil, and the activities of microorganisms can also help roots integrate into the soil. The seedlings have gone through a low temperature climate in winter, and the self-protection of seedlings strengthens their own adaptability, that is, the low temperature helps the seedlings to adapt to the environment quickly after the beginning of spring, sending out new roots and buds, waiting for flowering. Although the leaves of the seedlings transplanted in autumn withered quickly, this is the sign of the enhanced awareness of self-protection of the seedlings, although it is not handsome, but its adaptability is quite strong.

Transplanting seedlings in spring: the sun radiates less heat to the ground in spring, the soil temperature is very high, and the microorganisms in the soil are also dormant. Transplanting seedlings at this time is to put the root system in a low temperature environment. The root system is dormant at this time. Low temperature will accelerate root respiration, decompose root cell nutrients, weaken the internal structure of the root system, it is difficult to adapt to this environment, only when the soil temperature rises. The root system adapts slowly, and the leaves of the seedlings will not fall off naturally in the lower temperature environment, but the internal nutrients of the leaves are decomposing.

Generally speaking, transplanting seedlings in autumn is better than Spring Festival, and the survival rate is also higher. although the leaves of seedlings transplanted in autumn withered, on the surface, the seedlings are not dead, in fact, they are not dead, just to protect themselves. in order to better adapt to the performance of the environment.

Pay attention to these points in transplanting, there are many fewer diseases in the later stage.

When transplanting seedlings, pay attention to the following specific technical points, which will play a significant role in the prevention of later diseases.

Before transplanting

① strengthens the management of refining seedling stage

Seedling emergence in nursery land is generally non-toxic and disease-free, but there are many ways to produce diseases after transportation, seedling refining and human contact. Therefore, it is necessary to strengthen the management of the seedling stage to avoid the existence of diseases in the seedling stage.

Such as: pay attention to fertilizer management, avoid the situation of de-fatting, can avoid the emergence of "disease-prone" physique due to de-fatting in the seedling stage. Another example: excessive fertilizer in the seedling stage is very likely to lead to root damage, and the probability of root black rot after transplanting is geometrically increased. For example, if the growth environment in the seedling stage is too poor (near the livestock enclosure; near the fallen oil, pollen and other trees, etc.), the probability of contracting virus disease is significantly increased after transplanting. Pay attention to the management at the seedling stage and avoid improper management, which can effectively avoid root black rot, mosaic disease and various virus diseases in the later stage.

②, do not omit the disinfection of Qiantian block.

Many farmers omitted the step of field disinfection before transplanting. In fact, whether it is the winter fallow field or the former cropping field, there are inevitably various types of viruses, germs and even pests in the field. Before transplanting, some necessary pest control measures should be taken according to local conditions.

When transplanting

Strict row direction, row spacing and plant spacing of ① field

Uniform row direction, row spacing and plant spacing are actually effective measures to ensure field ventilation and light uniformity, which can avoid all kinds of diseases caused by poor ventilation and uneven light.

② does a good job of rational fertilization

Improper application of fertilizer during transplanting can easily cause fertilizer to burn seedlings. The seedlings burned with heavy fertilizer can directly lead to the death of seedlings after transplanting, and the lighter ones may also lead to the "burn" of rhizomes due to fertilizer, resulting in short-growing or even late plant death.

③ does a good job of hygiene during transplanting.

In the process of contact with seedlings transplanting, it is necessary to fully do a good job in disinfection of relevant operators and tools, and smoking is strictly prohibited in the process of transplanting.

④ select strong and transplant, weak seedlings are trained again

Selection and transplanting will be done, but it is very undesirable to discard the remaining relatively weak seedlings. On the one hand, it is a waste of bought seedlings, and on the other hand, it is impossible to guarantee the number of transplants. If the weaker seedlings continue to refine the seedlings in the seedling pool for one or two days, they can also reach the standard of high-quality seedlings, and all the seedlings should be transplanted.

After transplanting

Everything you want to know about transplanting seedlings is here.

After transplanting, the field should be inspected regularly to check whether there are early signs of diseases and insect pests. If there are early symptoms, it should be in line with the concept of "prevention first, prevention and control combined" and "green ecological quality". Early treatment can be done early, and those who can use biological, physical and green means should use less chemical means to detect and control field diseases and insect pests early.
