Garlic is native to Central Asia and the Mediterranean region, in our country has more than 2,000 years of cultivation history, China is the world's main garlic production, consumption and exporters, garlic annual output accounts for about 90% of the world's total output.
Garlic is rich in nutrients, has high therapeutic and medicinal value, and is widely cultivated in various parts of China. Soon to enter the winter, the average daily temperature in various parts of our country is getting lower and lower, the growth rate of garlic after winter is very slow, if we strengthen the management of garlic before entering winter, the seedlings will not only grow thick, but also have strong frost damage resistance, and garlic yield in the coming year is high and not dry.
<h1 class="pgc-h-arrow-right" data-track="4" before the > overwintering, garlic seizes the time to do 3 o'clock, and the output will double in the next year</h1>
First, timely chasing overwintering fertilizer
Garlic is a shallow root plant, and the root group is mainly distributed in the soil layer 5 to 25 cm deep, and the ability to absorb nutrients is not strong. The key to whether garlic can safely overwinter and whether the yield is high lies in "rooting and protecting roots". Timely topdressing before winter can supplement nutrition for garlic seedlings, which is conducive to promoting the development of garlic root system, preventing garlic from appearing dry-tip yellow leaves, and garlic will grow thicker in the coming year, and the yield will be greatly improved.
We can topdress garlic in the 5 to 6 leaf stage before winter, 10 kg of urea per mu, 1000 kg of decomposed farm manure to promote the growth of seedlings and the development of roots, rotten farm manure can be ditched and applied, farm manure fertilizer has long efficiency, can continue to provide nutrition for the growth of garlic seedlings, in addition, farm manure has a certain thermal insulation effect, can enhance soil temperature, can enhance the wintering ability of garlic seedlings.
Note: Farm manure must be fully decomposed before application to avoid raw fertilizer fermentation and burn garlic roots, and cause the occurrence of insect pests such as garlic maggots. In addition, in order to prevent garlic from being frozen to death in the cold winter, the garlic head planted should try to choose varieties of large, less cloves, and garlic weighing more than 50 grams, and the garlic cloves that are moldy, softened, dry, and insect-moth are not suitable for planting.
In addition to soil topdressing, we would do another foliar topdressing. Garlic is a nitrogen-loving, potassium-loving crop, we are best sprayed potassium dihydrogen phosphate + brassica, potassium dihydrogen phosphate can supplement nutrition for garlic seedlings and improve the quality of garlic seedlings. In addition to increasing production, brassica can also significantly enhance the stress resistance of garlic seedlings (drought resistance, cold resistance, disease and pest resistance, etc.), which is conducive to the safe overwintering of garlic seedlings. We can spray with 100 g of potassium dihydrogen phosphate + 10 ml of brassicalin, mixed with 30 kg of water.
Second, after fertilization, water the wintering water
Garlic seedlings in the early stage of growth of the root system is not developed, the ability to absorb water is not strong, keeping the soil moist can not only promote root development, but also conducive to the cultivation of strong seedlings.
Watering garlic seedlings before wintering can irrigate warmer water into the farmland, which can slow down the decline of soil temperature (the specific heat capacity of water is large, and the decrease in water temperature will release heat energy), so as to achieve the purpose of anti-frost. The overwintering water of garlic seedlings can be carried out together with topdressing, generally irrigated 1 to 2 times.
Third, the prevention and control of diseases and insect pests
Garlic is susceptible to insect pests such as thrips, garlic maggots, whiteflies, easy to suffer from leaf blight, soft rot, rust, white rot, etc., diseases and insect pests will affect the growth and development of garlic seedlings stems and leaves and roots, and have a great impact on the improvement of garlic yield. We must focus on prevention of pests and diseases, so as to minimize losses.
Pest control: we can sprinkle grass and wood ash on garlic leaves and roots, the main component of grass and wood ash is "potassium carbonate", which is a natural high-quality potassium fertilizer, sprinkling grass and wood ash on garlic seedlings in addition to supplementing nutrition to garlic, but also inhibiting diseases and insect pests, maggots, aphids, red spiders, powdery mildew, rust have control effects. In addition, sprinkling grass and wood ash on the garlic seedling plot can also enhance the cold resistance of the garlic seedlings, which can help the garlic seedlings to overwinter safely.
Disease control: For the prevention and control of garlic diseases, we can spray 75% Bacillus Qing wettable powder 600 times liquid, or spray 500 times carbendazim wettable powder 500 times liquid. If the garlic seedlings have rust, we can spray 15% rust rather wet powder 500 times liquid.
<h1 class="pgc-h-arrow-right" data-track="23" > Considerations for high-yield garlic planting:</h1>
1. Control of sowing depth. As the saying goes, "dark onion and light garlic", garlic is suitable for shallow planting, the most suitable depth for sowing is 3 to 5cm, and the sowing depth will affect the emergence of garlic seedlings.
2. The choice of planting soil. For harvesting garlic from underground bulbs, we should choose sandy loam soil with loose soil, rich organic matter content, strong water retention and fertilizer retention ability to plant, and the loose soil is conducive to the full expansion of underground bulbs and the high yield of garlic.
3. Garlic elongation is the maximum efficiency period of potassium fertilizer. Potassium deficiency in the late stage of garlic has a great impact on yield, so we should apply potassium fertilizer 7 days before garlic extraction. At the same time, when the garlic is bent, it should be picked in time, if the garlic is picked too late, the garlic will consume a lot of nutrients, which will affect the expansion of the underground bulb.
The elongation of garlic and the early growth of garlic overlap, the expansion volume of underground garlic has approached the maximum amount of 50%, at this time the plant's nutrient requirements reach the maximum, so it is necessary to increase potassium fertilizer in time before critical garlic extraction. Water the garlic immediately after harvest to promote rapid expansion and weight gain of garlic head.
4, small full of garlic, left in the ground rotten. The meaning of this sentence is that if the garlic is not dug up during the small full season, then the garlic is easy to rot in the ground. This is due to the fact that the garlic has been fully expanded during the small full season, and the rain will become more after the small full, and the soil is too wet to easily lead to the rotting and blackening of the bulbs of garlic, which will seriously affect the quality of garlic.
In summary, garlic is an important spice and vegetable, the most common ingredient on the table of every household, and growing garlic has high economic value. It is about to enter winter, we should seize the time to do a good job of applying pre-winter fertilizer, watering overwintering, and preventing diseases and insect pests in advance, so that garlic seedlings will grow thicker and stronger in the coming year, and the yield of garlic will be higher.
