Planting garlic by means of mulching film can increase the time for garlic to be put on the market in advance, increase production, and generally increase yield by more than 10%. Below, will introduce the cultivation of garlic mulch in autumn, for the reference of garlic farmers.
First, choose good varieties. Cangshan garlic and Jinxiang garlic were selected. These two varieties are excellent garlic varieties in Shandong Province and are also important export varieties. Each garlic has 7 to 8 petals, a slightly purple skin, thin skin, garlic hypertrophy, spicy taste, good quality, belong to a species. Strong growth, strong cold resistance, high convulsions, good resistance to storage, suitable for autumn planting.
Second, the appropriate sowing. Garlic must be properly sown, too early, low emergence rate, and prone to flap cloves; too late, short pre-winter growth period, seedlings are too small, susceptible to frost damage, and affect the garlic yield and quality. In order to ensure that the number of leaves before the winter of garlic reaches 4 to 5 leaves, the suitable sowing date is generally from late September to early October in the central region of our province.
Third, soil preparation and fertilization. Garlic has a wide range of adaptability to the soil, sandy soil, loam and nocturnal land can be, but it is better to use slightly acidic soil with rich organic matter, deep soil, and good drainage. Planting garlic on this kind of soil has a well-developed root system, returns to early morning, twitches early, and has a large garlic head. It also has a strong spicy taste and is easy to grow garlic. Fine soil preparation and application of organic fertilizers are of great significance in improving garlic yield and improving quality. The land on which garlic is grown needs deep turning to improve the permeability of the soil, which is conducive to the activity of soil microorganisms and the transformation of soil nutrients, and is conducive to the development of roots and bulb hypertrophy. After harvesting, the upper crops should be ploughed and ridged as soon as possible, and the cultivated land should be turned 20-30 cm deep. Due to the cover film, it is not suitable to top-dress during the growth of garlic. Therefore, before sowing, it should be combined with a one-time application of base fertilizer at a single site. The quality circle fertilizer should be 5000 kg per mu, the cake fertilizer should be 80 kg, and the nitrogen, phosphorus and potassium ternary compound fertilizer should be 40 kg. Zinc sulfate 1.5 kg.
Fourth, seed cover film. Choose garlic heads that are big, garlic is large and neat, garlic is hard, and the color is white and fresh. The general requirements of 100 grams of garlic 100 grams weight, the local temperature stability at 18 ~ 19 Â°C, you can sow, so that when the winter up to 25 cm above the garlic, is conducive to safe winter. Planting requires spacing of 15 centimeters, spacing between 6 and 8 centimeters, ditching depth of 10 centimeters, arranging the species in the furrows, and keeping them upright, with a density of 40,000 to 50,000 plants per mu and then covering. Earth covered. When the film is covered, it is required that the film be flat on the surface without wrinkling, and there is no gap below the film, so that the film is tightly adhered to the surface so as to prevent weeds from breaking when the garlic is more than 50% seedlings. The film is broken with a sharp wire. On the hole, the diameter of the orifice is about 1 cm.
Fifth, field management. Immediately after sowing, one-time permeable water shall be poured. After the seedlings are discharged, the second water shall be poured and the antifreeze water shall be poured before the soil is frozen. Cover grass curtains or corn stalks several days later to prevent cold and drought and ensure safe wintering of garlic sprouts. Before and after the â€œSpring Equinoxâ€, the ground cover shall be cleared and water shall be selected in sunny and warm weather to promote the growth of garlic sprouts as early as possible. From the beginning of April to the end of April, according to the waterlogging situation, one tree was watered, and the other was 2 to 3 times with water. Generally, 15 kilograms of urea was topdressed and watering was stopped 3 to 4 days before the picking. After harvesting, garlic sprouts should always keep the soil moist and promote the rapid growth of garlic until watering is stopped 2 to 3 days before harvest.
Six, pest control. When the garlic grows up to 2 leaves and 1 heart, use highly efficient and low-toxic pesticides such as beta-cypermethrin to control pests such as garlic thrips and garlic flies. In mid-March, attention was paid to the prevention and treatment of garlic sprouts and garlic sprouts. Use 50% polymyxin or 65% triamcinolone 1000 times to control garlic leaf blight.
Seven, timely harvest. In the central and southern regions of our province, mulching garlic is harvested in mid-to-late May under normal weather conditions. At this time, most of the plant leaves have dried up and the pseudo-stem becomes soft. This is the best time for harvesting. You can seize the favorable time and higher prices to sell fresh garlic in time. If the market is not good, it can be dried and sold in the wrong season. Dried garlic or garlic yellow production in winter.
