What is the reason for the slow emergence of garlic and how to solve it?

The reason of slow emergence of garlic? In the autumn planting area of mulched garlic in Qixian county, Henan province, garlic will also emerge slowly after planting. What is the reason for the slow emergence of garlic after planting? Let's analyze from the following two points.

First, high temperature leads to slow emergence of garlic. Some people may ask what the appearance of garlic has to do with high temperature. Of course, the seeds of garlic are garlic cloves. When the ambient temperature is high, garlic seeds enter a dormant state, so that the germ in garlic cloves does not germinate. This is why garlic is stored in a cool and ventilated place when storing seeds.

The suitable temperature for garlic germination is 15~25℃. Too high or too low temperature will affect the germination and emergence of garlic seeds. It is required that the local temperature shall prevail when planting garlic, and the specific planting season and time are only a reference time. When the temperature is still high, garlic planting time should be postponed.

The local stable maximum temperature is below 26~27℃. At this time, garlic seeds have broken dormancy and can start planting garlic. The weather and temperature are abnormal this year. 654381October 2, the local maximum temperature is 32 degrees. Such a high temperature has a great influence on the germination and emergence of garlic after planting. Some farmers planted garlic before 65438+1 October1National Day, and the emergence of garlic was slow to varying degrees. Some farmers have planted garlic for half a month or even a month.

The main measure to avoid the slow emergence of garlic under the influence of high temperature after planting is to choose a good time when planting garlic, which is based on the local stable maximum temperature and the suitable temperature for garlic seeds to germinate and emerge.

Second, excessive planting leads to slow emergence of garlic. There is a saying in rural areas that garlic is planted shallowly and onion is planted deeply, indicating that when planting garlic, the depth of planting garlic should not be too deep.

If garlic is planted too deeply, the permeability of garlic seeds in deep soil will be reduced, and the respiration of seeds will be blocked, which will slow down the germ development and nutrient transformation of seeds, inhibit the growth and development of garlic seeds in deep soil, and slow down the emergence speed. On the other hand, after the seeds germinate, new buds grow out again, which is resisted by too many soil layers.

The main measures to avoid the slow emergence of garlic seeds are simple. It is a kind of shallow garlic. How shallow is it? Generally, it is appropriate to cover the terminal buds of garlic seeds with 1 cm soil layer in autumn.

To sum up, the emergence of garlic is mainly related to the temperature and depth of planting. The most important factor is the temperature when planting garlic, which has nothing to do with the nutritional conditions in the soil, because the nutrients needed for garlic germination and emergence are provided by seeds.

Grasp the suitable weather and temperature conditions and reasonable planting depth when planting garlic, avoid the slow emergence of garlic, and make garlic emerge quickly, strongly and neatly.
