What kind of fertilizer is good for planting garlic? Do these four points well to harvest high yield and high yield garlic

Garlic is one of the most common food in our daily table dishes, which can be eaten raw or seasoned. At the same time, it is also a good crop to feed, as long as good fertilization management, high-yield garlic can be obtained. So, what kind of fertilizer should be used to grow garlic? The following four points must be grasped.

What kind of fertilizer should be used to grow garlic?

1. The fertilization of garlic is mainly based on base fertilizer, supplemented by topdressing, mainly high-quality organic fertilizer and supplemented by chemical fertilizer.

two。 Garlic base fertilizer: 3000-3500kg/ mu of rotten farm manure, 50kg/ mu of calcium, and 30kg/ mu of special compound fertilizer for garlic should be applied during soil preparation. Fertilizer and soil should be evenly mixed.

3. Topdressing of garlic: according to the fertilizer characteristics and growth trend of garlic during the whole growth period, garlic with garlic head and garlic moss as the target product generally needs topdressing for 2-3 times.

4. For the first time, N fertilizer was the main fertilizer in the mother stage (4-5 leaves), and urea 15-20kg was applied per mu.

5. The second time in the bulb expansion stage (9-10 leaves), that is, the garlic mu will be exposed to bud again, urea 10-15kg per mu, potassium sulfate compound fertilizer (15:15:15) 30-40kg.

6. The third time, about 50% of moss was applied with potassium sulfate compound fertilizer (15:15:15) 15-20kg/ mu. Garlic with garlic seedlings as the target product is only treated with mother fertilizer, and topdressing is prohibited 30 days before garlic seedlings are harvested. Each fertilization is combined with irrigation.

7. In addition, in the first ten days of April in the second year of garlic planting, combined with watering strong seedlings, urea 10kg, a quick-acting fertilizer, was applied every 667m2. In the middle of April, every 667m2 was sprayed with 0.5kg potassium dihydrogen phosphate dissolved in 50kg water.

Four-point harvest of high-yield and high-yield garlic

1. For soil preparation and fertilization, fertile fields with sunny, leeward, convenient drainage and irrigation, strong water and fertility conservation should be selected, the residues of previous crops should be removed, the sun should be ploughed in time, the bottom water should be irrigated, and the basic fertilizer should be applied (5000kg / mu of high-quality organic fertilizer and 20kg / 30kg of phosphorus and potash fertilizer), and the border surface should be kept flat and soft before sowing.

two。 Sowing and raising seedlings should be timely sowing, reasonable close planting, and seed dressing with new high-fat membrane before sowing (which can ward off underground diseases and insects, isolate virus infection, strengthen seed respiration, and improve seed germination rate). Generally, the suitable depth of sowing is 3-4 cm. Watering thoroughly after sowing, in order to prevent drought, 800-fold liquid of new high-fat film was sprayed to keep heat and preserve soil moisture, prevent soil plate and improve seedling emergence rate.

3. In field management, according to the growth needs of garlic, timely watering and topdressing, ploughing and weeding, spraying Zhuangtuanling in the growing period, and spraying Diguo Zhuangtieling during the pregnant bolting period should also thicken the nutrient transport ducts of underground fruits, improve the swelling vitality of ground fruits, and enhance plant disease resistance. increase the yield of garlic.

4. Disease and pest control, garlic is prone to leaf blight, dry rot, gray mold, virus and other diseases during the growing period. According to the requirements of plant protection, targeted agents (such as 20% virus nemesis, 40% Shijiale suspension, 50% Duofu wettable powder) should be sprayed in time to kill the fungicides, while spraying 800-fold solution of new high-fat film to enhance the efficacy.

The efficacy and function of garlic

1. Strong sterilization, sulfur compounds in garlic have strong antibacterial and anti-inflammatory effects, inhibit and kill a variety of cocci, bacilli, fungi and viruses, which is the strongest antibacterial activity in natural plants found at present.

two。 Reducing blood sugar, garlic can promote the secretion of insulin, increase the absorption of glucose by tissue cells, improve human glucose tolerance, rapidly reduce the level of blood sugar in the body, and kill various bacteria that cause diabetes caused by infection. thus effectively prevent and treat diabetes.

3. To prevent colds, garlic contains a kind of capsaicin called propylene sulfide, which has a good killing effect on pathogens and parasites. It can prevent colds and relieve cold symptoms such as fever, cough, sore throat and stuffy nose.

4. To protect the liver, the trace element selenium in garlic can protect the liver by participating in the aerobic metabolism of the blood, removing toxins and reducing the detoxification burden of the liver.

5. Detoxification and clearing intestines, garlic can effectively inhibit and kill Helicobacter pylori and other bacterial viruses that cause gastrointestinal diseases, remove gastrointestinal toxic substances, stimulate gastrointestinal mucosa, promote appetite and accelerate digestion.
