What is the use of the latest garlic film mulching

Garlic is an important side dish in our daily life, and garlic is grown in almost every household in the countryside. Home farming may not be much regulated, but many people will cover the surface with a film, either plastic film or straw. It is said that this can increase the yield and quality of garlic. So what's the use of plastic mulching when growing garlic? Let's take a look at it.

1. Control insects and weeds

Now everyone planting garlic will use new high-fat membrane and appropriate amount of herbicides after sowing, which can effectively prevent insect pests and control the growth of weeds. And after spraying, covering it with a layer of straw can weaken the growth of pests and reduce the living space of pests and weeds. Because after mulching, the light in the field was reduced, the growth of weeds was inhibited, and herbicides were sprayed, and the growth of weeds was hindered by two defenses. The same is true for pest control, to prevent the loss of new high-fat membranes and strengthen the efficacy.

2. Shading and water conservation

The planting time of garlic varies from region to region, and it is usually planted from August to September in the south. But at this time, the sun is still relatively strong at noon, the rate of water evaporation will also accelerate, and too strong light will also inhibit the germination of garlic seeds. Timely plastic film mulching after sowing can not only effectively reduce the intensity of solar radiation, but also prevent excessive sun from accelerating soil water evaporation and affecting soil moisture and seed germination. And the germination of seeds is directly related to the growth and growth in the later stage.

3. Increase the temperature and keep warm

The ripening season of garlic is generally in winter and spring, and the temperature is lower in winter and spring, especially in the north. In the process of garlic growth, if the temperature is lower than five degrees below zero, it is easy to produce freezing injury, which has a great impact on the growth. Therefore, plastic film mulching can increase the temperature in the field, slow down the rate of temperature decline, and ensure that garlic can safely survive the winter. After the safe overwintering temperature gradually rises, because of the good heat preservation measures, the green rate of garlic will also become faster, which is conducive to the later growth and quality.

4. Keep fat and moisture

Garlic is a fertilizer-loving crop, especially when it lasts for a long time during the rainy season. The long-term erosion of the soil by Rain Water will lead to the loss of a large amount of fertilizer, which will not only increase the cost of planting, but also affect the growth of garlic. Due to the lack of fertilizer in the soil, the soil is easy to solidify after the rain stops, which is extremely disadvantageous to the germination and root nutrition absorption of garlic. Plastic film mulching can effectively prevent Rain Water from scouring, reduce fertilizer loss, protect the soil and prevent Rain Water from destroying the growing environment of garlic.

The above is the role of planting garlic film mulching, I think we all know why planting garlic should be covered with film on it. It not only protects the growth environment of garlic, but also can effectively promote the growth of garlic. However, when covering, we should also pay attention to that the straw should not be too thick, otherwise it can not only inhibit the growth of weeds, but also hinder the germination of garlic.
