Secondary Film covering Technology of garlic

The cultivation technology of garlic with double-layer plastic film mulching can increase the yield, put on the market earlier and increase the benefit. The following editor will introduce the secondary covering technology of garlic for you.

First, garlic secondary film covering technology.

When mulching plastic film, the plastic film is required to spread flat on the border surface without wrinkles, and there is no gap under the plastic film, so that the plastic film is close to the border surface so as not to breed weeds. When the garlic seedling is more than 50%, the film is broken, and the sharp wire is used to pierce the hole in the film, and the diameter of the hole is about 1 cm.

2. Key points of planting techniques of garlic in greenhouse

1. Select garlic species

The varieties with large petals, high yield, short dormancy period, seedling emergence and fast growth were selected. It is usually planted in spring and autumn.

two。 Pre-broadcast preparation

The varieties with large petals, high yield, short dormancy period, seedling emergence and fast growth were selected. Soak the garlic seeds in 30 ℃-50 ℃ warm water for about 30 hours to make the garlic absorb water and expand. Then remove the drained water and pile it up for about 12 hours, and then dig out the garlic stalks. If the sowing area is large and the soaking amount is large, it can also be sowed one week in advance without digging the stem.

3. Put garlic to press the soil

About 15 kilograms of garlic cloves are buried per square meter, and the tighter the better between the cloves and cloves, and the larger gap is filled with smaller cloves. After the garlic cloves were set up, the garlic cloves were covered with fine sand with a thickness of 3 cm, and the surface was sprayed with 600-fold liquid of new high-fat membrane to improve the seedling emergence rate.

4. Water management

The garlic seedlings were watered with a new high-fat membrane diluent with a temperature of not less than 15 ℃, followed by heavy water from cultivation to the early growth stage, reclaimed water in the middle stage with a height of about 15 cm, and small water in the late growth stage 3-4 days before harvest. The frequency of watering depends on the dryness and wetness of the soil on the bed.

5. Temperature and light

It is necessary to keep the film surface of the greenhouse clean and improve the light transmittance so as to obtain more light time. Spraying photosynthetic nutrient film fertilizer can help garlic seedlings absorb a lot of light energy, and have the nutrition of conventional fertilizers, so that the growth and development of garlic seedlings is better.

6. Timely harvest

When the garlic seedlings grow to a height of about 35 cm and the leaves tilt slightly, it is the right time for harvest and should be harvested in time. After the stubble garlic seedlings are harvested, using the same management method mentioned above, new garlic seedlings can grow after 20 days. When the new garlic seedlings grow to about 30cm, they can be harvested and sold again. With such circular management and harvest, 3-4 crops can be harvested continuously.

Garlic is not difficult to grow and can grow everywhere, with high yield and good quality. Such as Shandong Linyi and other places large-scale planting, the economic benefit is considerable.
