China's garlic varieties can be described as very rich, there are many planting areas in the north and south, so there are many excellent garlic varieties. Because the taste of garlic is relatively strong, many people avoid it from garlic, but if garlic is used as a pickled product, it is still very good to eat. Now Xiaobian says how to grow garlic?
1, preparation before the broadcast
Before sowing, finely plan the soil to make the soil fine and the ground flat. In deep ploughing, it is necessary to plow 20 cm or so, and at the same time, it can also combine the soil preparation to control the pH of the soil within 5, 5 to 0.6. Because if the pH of the soil is too acidic, the roots of the garlic will become thicker, stop or prolong the growth, and the pH of the soil will be too alkaline, which will cause the species to rot and grow poorly. When selecting garlic varieties, you should choose fresh garlic with white color, white garlic, sturdy and hard, no injury and no disease. The requirements for garlic are generally above 400g, and 50% carbendazim wettability can be used before sowing. Soak the seeds with powder 500 times, soaking time within 12-16 hours, this can prevent the occurrence of fungal diseases.
2, sowing
The season of sowing depends on the local climatic conditions and the requirements of the outside world for different growth periods. In the south of 35 degrees north latitude, the main planting in autumn is selected; north of the north latitude and north latitude is 38 degrees, which is suitable for sowing in early spring and harvesting garlic before and after the summer solstice. The sowing cycle of garlic in spring is generally about 90 to 110 days, and the growth cycle of garlic in autumn is about 220 to 280 days. It is suitable for sowing in late August to late September.
In the cold winter season, garlic seedlings can grow to more than 25 cm, which is conducive to the safe winter of garlic. Before planting, first dig a 10 cm seeding ditch at a distance of 20 cm and apply a small amount of seed fertilizer. When planting, the garlic cloves are planted in an upright manner. The back of the petals should be parallel to the seeding line. After that, cover the soil with 3 cm for watering. You can also spray some herbicide acetochlor to prevent the weeds from growing. It is. When covering the film, be sure to cover the mulch and cover it evenly without wrinkles.
3. Scientific fertilization
Garlic prefers NPK total-effect organic fertilizer, so it is necessary to do a good job of nitrogen control, phosphorus increase, potassium supplementation and micro-fertilization. It is not suitable for top dressing during the growth of garlic. Therefore, it is necessary to apply the base fertilizer once before sowing. The zinc sulfate is 22.5kg/hm2, the fertilized high-quality organic fertilizer is 45t/hm2, the superphosphate is 1200kg/hm2, and the potassium sulfate compound fertilizer is applied. 375kg/hm2, 1200kg/hm2 of decomposed cake, 750kg/hm of urea, 375kg/hm2 of potassium sulfate compound fertilizer. Because the roots of garlic absorb weak water and fertilizer, it needs to be fertilized in time. Generally, it can be used three or four times.
4, reasonable irrigation
After the application of Qi Miao fertilizer, if the land is relatively dry, irrigation can be carried out once to promote seedling growth. In the early stage of seedling growth, it is necessary to control the irrigation, and do the drainage work in the rainy days. Before wintering, the rainfall is less. When the land is relatively dry, the irrigation is carried out once. After the winter, the temperature starts to rise, and the seedlings enter the vigorous growth. It needs timely irrigation to promote the growth of the garlic leaves and the thickening of the pseudo stems.
5, cultivating weeding
In the seedling growth period, when the weeds are just sprouting, it is necessary to carry out cultivating and weeding. The weeds that are difficult to cultivate between the plants should be removed early, so that weeds and garlic seedlings should compete for fertilizer and nutrients. Before sowing to emergence, you can spray herbicides to prevent weeds.
6, timely harvest
The green garlic can be harvested within 60 to 70 days of emergence. The specific harvest time depends on the local garlic market. After harvesting, it cannot be washed with water, otherwise it will affect the sales value of garlic.
One thing to note is that you should not wait until the leaves on the ground are all withered before you pick the garlic. It is easy to know that the garlic is not harvested in time during the rainy season. It is easy to cause the garlic petals to scatter and rot, neither in storage nor in storage. As a variety of the coming year.
