In the small helper high-yield exchange group, there are several friends who grow garlic to discuss the situation of garlic seedlings, one group friend said that the garlic planted in mid-September, now the seedlings are good, basically out of the whole seedlings, while another group friend said that the garlic he sowed in early September, it seems that there are still many unsuprown cases.
Many areas of autumn sowing garlic has been planted for a period of time, garlic seedlings slow problem, every year will receive a lot of farmers to consult, garlic seedlings slow reasons, under normal circumstances, in the temperature, humidity are appropriate, after sowing, 7-10 days can germinate seedlings, if the emergence of seedlings is too slow, but a few days later will also emerge seedlings, affecting the normal growth of garlic, if garlic seedlings are slow, eventually has not been out of seedlings, not only reduce the yield, but also missed the time of replanting.
Therefore, to understand the common reasons for the slow emergence of garlic seedlings, it is very important to take preventive measures in advance, if the garlic has been sown, for the phenomenon of slow emergence, it is also necessary to do the corresponding remedial measures to ensure the yield of garlic.
Reason 1: Garlic seed problem
It is also common for garlic seed problems to cause slow emergence or no seedlings, one of which may be that the purchased garlic seeds are not suitable for local planting, and the climate is not suitable for growth after sowing; second, the self-retained garlic, due to the long retention period, has been planted for several years, resulting in a decrease in germination rate, delaying the emergence of seedlings or will not emerge; third, some farmers' self-retained garlic seeds, not well preserved, encountered rainfall, garlic seeds tide, mold, after sowing, resulting in slow emergence or no seedlings.
In view of this situation, you can do germination experiments about a week before sowing, bury more than a dozen or twenty garlic in the soil in advance, check the germination rate, if more than 80% can germinate can be planted, if the germination rate is less than half, it is recommended to replace the garlic seed, if it has been planted, you can replace the garlic seed after replanting.
Reason two: the problem of sowing too deeply
Under normal circumstances, the sowing depth of garlic is 3-5cm, if the moisture is not very good, it can be appropriately increased to 5-6cm, garlic sowing is less than 3cm, it is easy to expose the soil, can not germinate seedlings, and if sown too deeply, it will lead to late emergence or no seedlings.
At present, sowing garlic, most of them are still artificial, in this case, it is not easy to judge the sowing depth of garlic, after all, artificial and machine are different, artificial strength is light and heavy, it is inevitable that some garlic sown too deep, resulting in too late emergence.
In this case, you can wait a few more days, under normal circumstances, a few days later seedlings do not affect the overall situation, if the sowing is too deep, such as more than 10cm, in this case, waiting a few days late may not be able to emerge seedlings, and eventually there will be a lack of seedlings and ridges. Garlic needs to be replanted in time, the sooner the better.
Reason three: the problem of moisture
When garlic is sown, the moisture in the field is too dry or the humidity is too large, which is not conducive to the emergence of garlic seedlings, and the light will delay the emergence time of garlic seedlings, and in serious cases, garlic cannot emerge normally.
The soil is too arid, and after garlic is sown, it is unable to absorb sufficient water and fertilizer, and the germination rate of garlic seeds is slowed down, and the germination rate will become slower. The soil is too humid, after garlic sowing, the air content in the soil is insufficient, garlic seeds can not get sufficient oxygen, will also delay the rate of emergence and reduce the emergence rate.
In view of this situation, if it is relatively arid, it is necessary to irrigate in time, but do not directly flood irrigation, for the situation of large soil moisture, you can wait for a few days to see, if half a month has passed, the plot that has not yet emerged from the seedlings needs to be replanted, in addition, for the garlic that has been seedlings, weak seedlings may be formed, and foliar fertilizer or plant growth regulators need to be sprayed to promote normal growth.
Reason four: temperature problems
Garlic has a suitable germination temperature, under normal circumstances, 15-25 degrees is the best, if the temperature is lower or higher than this temperature range for a long time, it may also lead to garlic germination too slow and non-germination. This is to talk about the time of garlic sowing, sowing too early, the temperature is relatively high, sowing too late, the temperature is relatively low, the best sowing period is very important.
In the case of the eastern Henan region, garlic sowing is concentrated in early to mid-September, some earlier areas can be sown in late August, and a small number of farmers sow in late September, and the sowing time should be determined according to the specific situation.
If the garlic has not been sown, you can check the local temperature, choose the right time to sow, if you have sown, encounter low temperature or high temperature weather, you can wait for ten days and a half to see the germination of garlic seedlings, if there is a lack of seedlings, timely replanting, if there is too much lack of seedlings, you can consider re-sowing.
Reason five: garlic seeds are not toppled
When planting garlic, some farmers will use self-retained seeds, you need to break the garlic into a garlic clove, and the head of the garlic will have a top cover, this thing needs to be broken off, if not broken off, it will affect the germination rate of garlic seedlings, you can observe, the purchased garlic seeds, is not the top cover, only in the time of self-retention, in order to figure out the convenience, some garlic cloves of the top cover is not removed, after sowing, than the top of the garlic cloves to the top of the seedling time.
In view of this situation, if it has not been sown, whether the garlic seed has been reduced to the top, if it has been sown, wait for a few days, check the emergence of seedlings and then make a decision, and the replanting will be replanted in time.
The above 5 points are the main reasons for the slow emergence of garlic seedlings or not seedlings, for the problem of slow emergence of garlic seedlings, there are farmers who say that soaking in water for a few hours before sowing can improve the speed of seedling emergence, which is feasible, but it is recommended that after soaking, do not forget to mix seeds and then sow seeds.
