Garlic using mulching film cultivation technology has a significant effect on increasing yield. The effect of mulching film. After the garlic is covered with the mulch, it has the following obvious effects: 1 Improved environmental conditions. After the mulch film is covered, the ground temperature at 5 cm can be increased by 2 to 3 °C before winter. Therefore, the growth of garlic seedlings before winter is accelerated, the seedlings are strong and the cold resistance is strong. In addition, the winter ground temperature is higher, so the wintering rate due to low temperature is greatly reduced, about 5 times less. Hunchun, due to the high ground temperature of 2.6 ~ 3.7 ° C, garlic seedlings return to early, fast growth, large plant growth, large leaf area, laid the foundation for high yield. The impermeability of the mulch film reduces the amount of soil water evaporation, which is conducive to soil moisture conservation and drought prevention. Therefore, after the mulching of garlic, the number of watering can be reduced, the soil moisture is suitable, and the early spring avoids the disadvantages of watering and lowering the ground temperature, which creates favorable conditions for plant growth. After the mulching film is covered, the soil water retention and fertility are enhanced, the nutrient utilization rate is improved, the soil is loosened, the floor slab which is excessively watered is prevented, and the soil environmental conditions are effectively improved. Garlic coverage of the mulch also reduces the occurrence of pests and diseases. The mulch prevents the breeding flies from laying around the roots of the garlic, reducing the damage of the roots. Film mulching also inhibits the occurrence and damage of weeds. 2 promoted the growth and development of garlic. Due to the improvement of environmental conditions, under the condition of garlic mulching, the plants grow robustly, the roots are developed, and the leaf area is large. The leaf area index can be increased by 0.025. 3 premature and high yield. Due to the temperature effect of the mulching film, after the garlic mulching film is cultivated, the twitching period can be 6 to 10 days in advance, and the maturity period is 5 to 8 days in advance. Early maturity creates conditions for early tempering, which can effectively regulate the cultivation period of the sorghum crops. Covered with plastic film, garlic can increase the production of garlic by 55.35% and increase the yield of garlic by 44.8%. (2) Cultivation techniques 1 Soil preparation and fertilization. Fine soil preparation can improve the coverage of the film. After the mulching film is covered, the garlic absorbs more fertilizer, so the organic fertilizer should be added to reduce the labor trouble of the top dressing. Small sorghum is generally used for mulching. The width is determined by the width of the mulch film. 2 cover film. Generally, the seed is first sown and the film is covered. The film is tightly covered and pressed. Make the film close to the ground; no gaps, no wrinkles in the film, and holes in the soil in time. 3 sowing. Due to the prolongation of the growth period after the plastic film is covered, the autumn sowing garlic can be properly broadcasted for 5 to 7 days. The density should be appropriately dilute, and 35,000 to 38,000 plants per mu are suitable. The sowing method is the same as autumn. 4 seedling management. Immediately after sowing the film, water is poured to promote the rooting of the garlic clove. When the seedlings are near, the water is poured once more to facilitate the emergence of the seedlings, breaking the mulch and continuing to grow. The young shoots that have no film on top can help them to artificially break the membrane. The smaller the mouth of the artificial membrane is, the better. In the seedling growth stage, the seedling water is irrigated once, and in winter, the wintering water is poured once. During the growth period, it should be patrolled frequently. When the seedlings are pressed under the membrane, they should be immediately removed from the membrane to prevent the seedlings from growing under the membrane. 5 middle and late management. In the flower bud and bud differentiation stage, the mulch film should still be protected. The heat preservation effect is exerted until the mulch film is removed before the convulsion. Other management is cultivated with autumn sowing garlic.
