The use of plastic film covering for cultivation can improve the temperature and moisture conditions of the soil and near ground, playing a role in increasingtemperatureMaintain soil moisture, improve soil properties, enhance soil nutrient supply, andFertilizer utilization rateImproving lighting conditions and reducing the harm of weeds and pests.
1. Keep warm and promote the decomposition and release of soil nutrients
2. Moisturize and improve survival rate
The soil moisture in fields mainly comes from rainfall, in addition to irrigation. After covering with plastic film, on the one hand, the obstruction of the film reduces the evaporation of soil moisture, resulting in slow loss; And it forms water droplets inside the membrane before falling onto the soil surface, reducing the loss of soil moisture and playing a role in retaining soil moisture. On the other hand, plastic film can also prevent a large amount of rainwater from entering the ridges during heavy rainfall, which can play a role in flood prevention.
3. Promote growth and development
The application of plastic film covering increases the temperature and humidity of the soil, which is beneficial for early growth and rapid development, and promotes the growth and development of plants. The growth period of fields covered with plastic film is shortened to about one week compared to those without plastic film.
4. Reduce the harm of weeds and aphids
Plastic film covering can inhibit weed growth. Generally, weeds covered with plastic film are reduced by more than one-third compared to those not covered with plastic film. When combined with herbicides, the effect of weed control is more significant. After spraying herbicides, the weeds covered with film can reduce the number of weeds compared to those without film89.4-94.8%. Plastic film has a reflective effect and can partially repel aphids, inhibit their breeding and reproduction, reduce harm and spread of diseases.
5. Negative effects of plastic film covering
Plastic film covering has both positive and negative effects. For example, although plastic film covering has the function of water retention, it hinders external precipitation from entering the ridges. If corresponding ridge types or other measures are not taken in some areas, it may lead to water deficit in tobacco plants during the vigorous growth period, affecting normal growth; If continuous rainfall occurs, it can easily cause severe water damage, deteriorate soil permeability, hinder water evaporation, and also affect the growth of tobacco plants. Therefore, combining with the local production reality to seek benefits and avoid harm, developing practical and feasible plastic film covering production technology, fully utilizing the role of plastic film, and adopting corresponding supporting technical measures are the basis for the successful planting of plastic film covering.
