Importance of plastic mulching in vegetable crops

What is mulching?

Land or plants to create favorable conditions for plant growth, development, and efficient crop production. The process of covering is called mulching. The common denominator is "covering the mother".

Advantages of mulching

• It prevents direct evaporation of moisture from the soil. Groundwater does not come in direct contact with the atmosphere and also does not fall directly on the ground due to sunlight. The bottom of the plastic stays inside in the form of drops. And again it is absorbed into the soil. So in this way the wastage of water in the soil stops.

When it is very difficult to control weeds in vegetable cultivation, mulch prevents weed germination from light so that weeds do not grow.

Since the plastic cover is spread on the ground, direct sunlight does not fall on the ground. But the plastic falls on and the plastic heats up. According to the scientific rule, since plastic has low thermal conductivity, sunlight softens the plastic.But the heat of the sun cannot bring the high temperature of the soil. Due to this plastic coating and the air coating in the space between the plastic layer and the ground acts as insulator. So it is very important to maintain the temperature even at night. Thus the direct effect of summer heat and winter cold on the soil can be avoided with plastic.

This is a beneficial and simple, optimal and robust method to remove viruses, bacteria or other harmful elements from the soil i.e. to disinfect the soil and to prevent the destruction of essential elements by solar energy.

Prevents soil erosion caused by wind and water.

According to research, seeds germinate 2-3 days earlier than mulch.

Reduces the amount of worms in the soil.

Prolonged moisture retention increases the duration between two waters.

Disadvantages

It costs a lot in the beginning

The need of men arises.

Black film is more likely to burn at higher temperatures.

On standing crops, intercropping, weeding and manure spraying are difficult.

Damage to reptiles and mice.

Used plastics should be collected from the field after disintegration and disposed of properly

It is not advisable to cover plastic in areas with high humidity, where waterlogging occurs.

A variety of plastics are used for mulching such as polyvinyl chloride (PVC), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE). ) In all these plastic malls LLDPE. This means that linear low density polyethylene plastics have become more prevalent.

Its demand among farmers remains high. Because it has two distinctive features. What is very important compared to other plastics is that although they are very thin, they are strong and do not rupture quickly and since they are thin they can be mulched on high ground with low weight and low cost.

And since it is more resistant to falling holes, the weeds stop growing by cracking or piercing the plastic. This type of plastic mulching uses a plastic sheet 0.05 mm thick.

1. Black mulch
2. Transparent mulch
3. Two Side Color Mulch (Yellow / Black, White / Black, Silver / Black, Red / Black)
4. Degradable mulch (photo degradable, biodegradable)

Basic properties of plastic mulch:

Should be air proof so that no moisture or steam is retained.
 
Thermal proof for temperature maintenance and prevention of evaporation

It needs to be durable for at least one harvest season.

Selection of plastic based on inertia
Mainly available in the market up to 5-120 microns but for vegetables 15-7 microns
It is advisable to use (60-100 gauge).

Selection based on the width of the plastic
This is based on the inter-row spacing. Generally 1 to 2 meter wide film can be easily adapted in different situations

Points to consider when using plastic

Plastic does not crack by making round holes instead of squares.

The cover only collects moisture. The full crop water requirement cannot be met,

Cover is more effective when there is moisture in the soil.

Apply a thin layer of clay over its edges or press its edges into the ground to give the plastic a proper grip.

Make sure there is as little air as possible between the soil and the plastic.

Method of application of mulching in vegetable crop

To be done while making mulching bed for vegetable crop.
First make lines in the field
To prepare the bed.
 Mix manure and organic manure while making the bed
